10 @class wxGridCellRenderer
12 This class is responsible for actually drawing the cell in the grid. You
13 may pass it to the wxGridCellAttr (below) to change the format of one given
14 cell or to wxGrid::SetDefaultRenderer() to change the view of all cells.
15 This is an abstract class, and you will normally use one of the predefined
16 derived classes or derive your own class from it.

37 the style specified by the attribute and the default or selected state
38 corresponding to the isSelected value.
40 This pure virtual function has a default implementation which will
41 prepare the DC using the given attribute: it will draw the rectangle
42 with the background colour from attr and set the text colour and font.

765 Get the alignment to use for the cell with the given attribute.
767 If this attribute doesn't specify any alignment, the default attribute
768 alignment is used (which can be changed using

771 Notice that @a hAlign and @a vAlign values are always overwritten by
772 this function, use GetNonDefaultAlignment() if this is not desirable.
775 Horizontal alignment is returned here if this argument is non-@NULL.
776 It is one of wxALIGN_LEFT, wxALIGN_CENTRE or wxALIGN_RIGHT.
778 Vertical alignment is returned here if this argument is non-@NULL.

803 means that they must be initialized before calling this function and
804 that their values will be preserved unchanged if they are different
805 from wxALIGN_INVALID.

1064 Class providing attributes to be used for the grid cells.
1066 This class both defines an interface which grid cell attributes providers
1067 should implement -- and which can be implemented differently in derived
1068 classes -- and a default implementation of this interface which is often
1069 good enough to be used without modification, especially with not very large
1070 grids for which the efficiency of attributes storage hardly matters (see
1071 the discussion below).
1073 An object of this class can be associated with a wxGrid using
1074 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1075 intend to use the default provider as it is used by wxGridTableBase by
1078 Notice that while attributes provided by this class can be set for
1079 individual cells using SetAttr() or the entire rows or columns using
1080 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1084 The default implementation of this class stores the attributes passed to
1085 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1086 derived class may use its knowledge about how the attributes are used in
1087 your program to implement it much more efficiently: for example, using a
1088 special background colour for all even-numbered rows can be implemented by
1089 simply returning the same attribute from GetAttr() if the row number is
1090 even instead of having to store N/2 row attributes where N is the total
1091 number of rows in the grid.
1093 Notice that objects of this class can't be copied.
1095 class wxGridCellAttrProvider
: public wxClientDataContainer
1098 /// Trivial default constructor.
1099 wxGridCellAttrProvider();
1101 /// Destructor releases any attributes held by this class.
1102 virtual ~wxGridCellAttrProvider();
1105 Get the attribute to use for the specified cell.
1107 If wxGridCellAttr::Any is used as @a kind value, this function combines
1108 the attributes set for this cell using SetAttr() and those for its row
1109 or column (set with SetRowAttr() or SetColAttr() respectively), with
1110 the cell attribute having the highest precedence.
1112 Notice that the caller must call DecRef() on the returned pointer if it
1116 The row of the cell.
1118 The column of the cell.
1120 The kind of the attribute to return.
1122 The attribute to use which should be DecRef()'d by caller or @NULL
1123 if no attributes are defined for this cell.
1125 virtual wxGridCellAttr
*GetAttr(int row
, int col
,
1126 wxGridCellAttr::wxAttrKind kind
) const;
1131 All these functions take ownership of the attribute passed to them,
1132 i.e. will call DecRef() on it themselves later and so it should not be
1133 destroyed by the caller. And the attribute can be @NULL to reset a
1134 previously set value.
1138 /// Set attribute for the specified cell.
1139 virtual void SetAttr(wxGridCellAttr
*attr
, int row
, int col
);
1141 /// Set attribute for the specified row.
1142 virtual void SetRowAttr(wxGridCellAttr
*attr
, int row
);
1144 /// Set attribute for the specified column.
1145 virtual void SetColAttr(wxGridCellAttr
*attr
, int col
);
1150 Getting header renderers.
1152 These functions return the renderers for the given row or column header
1153 label and the corner window. Unlike cell attributes, these objects are
1154 not reference counted and are never @NULL so they are returned by
1155 reference and not pointer and DecRef() shouldn't (and can't) be called
1158 All these functions were added in wxWidgets 2.9.1.
1163 Return the renderer used for drawing column headers.
1165 By default wxGridColumnHeaderRendererDefault is returned.
1167 @see wxGrid::SetUseNativeColLabels(), wxGrid::UseNativeColHeader()
1171 virtual const wxGridColumnHeaderRenderer
& GetColumnHeaderRenderer(int col
);
1174 Return the renderer used for drawing row headers.
1176 By default wxGridRowHeaderRendererDefault is returned.
1180 virtual const wxGridRowHeaderRenderer
& GetRowHeaderRenderer(int row
);
1183 Return the renderer used for drawing the corner window.
1185 By default wxGridCornerHeaderRendererDefault is returned.
1189 virtual const wxGridCornerHeaderRenderer
& GetCornerRenderer();
1195 Represents coordinates of a grid cell.
1197 An object of this class is simply a (row, column) pair.
1199 class wxGridCellCoords
1203 Default constructor initializes the object to invalid state.
1205 Initially the row and column are both invalid (-1) and so operator!()
1206 for an uninitialized wxGridCellCoords returns false.
1211 Constructor taking a row and a column.
1213 wxGridCellCoords(int row
, int col
);
1216 Return the row of the coordinate.
1221 Set the row of the coordinate.
1226 Return the column of the coordinate.
1231 Set the column of the coordinate.
1236 Set the row and column of the coordinate.
1238 void Set(int row
, int col
);
1241 Assignment operator for coordinate types.
1243 wxGridCellCoords
& operator=(const wxGridCellCoords
& other
);
1248 bool operator==(const wxGridCellCoords
& other
) const;
1251 Inequality operator.
1253 bool operator!=(const wxGridCellCoords
& other
) const;
1256 Checks whether the coordinates are invalid.
1258 Returns false only if both row and column are -1. Notice that if either
1259 row or column (but not both) are -1, this method returns true even if
1260 the object is invalid. This is done because objects in such state
1261 should actually never exist, i.e. either both coordinates should be -1
1262 or none of them should be -1.
1264 bool operator!() const;
1268 @class wxGridTableBase
1270 The almost abstract base class for grid tables.
1272 A grid table is responsible for storing the grid data and, indirectly, grid
1273 cell attributes. The data can be stored in the way most convenient for the
1274 application but has to be provided in string form to wxGrid. It is also
1275 possible to provide cells values in other formats if appropriate, e.g. as
1278 This base class is not quite abstract as it implements a trivial strategy
1279 for storing the attributes by forwarding it to wxGridCellAttrProvider and
1280 also provides stubs for some other functions. However it does have a number
1281 of pure virtual methods which must be implemented in the derived classes.
1283 @see wxGridStringTable
1288 class wxGridTableBase
: public wxObject
1292 Default constructor.
1297 Destructor frees the attribute provider if it was created.
1299 virtual ~wxGridTableBase();
1302 Must be overridden to return the number of rows in the table.
1304 For backwards compatibility reasons, this method is not const.
1305 Use GetRowsCount() instead of it in const methods of derived table
1308 virtual int GetNumberRows() = 0;
1311 Must be overridden to return the number of columns in the table.
1313 For backwards compatibility reasons, this method is not const.
1314 Use GetColsCount() instead of it in const methods of derived table
1317 virtual int GetNumberCols() = 0;
1320 Return the number of rows in the table.
1322 This method is not virtual and is only provided as a convenience for
1323 the derived classes which can't call GetNumberRows() without a
1324 @c const_cast from their const methods.
1326 int GetRowsCount() const;
1329 Return the number of columns in the table.
1331 This method is not virtual and is only provided as a convenience for
1332 the derived classes which can't call GetNumberCols() without a
1333 @c const_cast from their const methods.
1335 int GetColsCount() const;
1339 @name Table Cell Accessors
1344 May be overridden to implement testing for empty cells.
1346 This method is used by the grid to test if the given cell is not used
1347 and so whether a neighbouring cell may overflow into it. By default it
1348 only returns true if the value of the given cell, as returned by
1349 GetValue(), is empty.
1351 virtual bool IsEmptyCell(int row
, int col
);
1354 Same as IsEmptyCell() but taking wxGridCellCoords.
1356 Notice that this method is not virtual, only IsEmptyCell() should be
1359 bool IsEmpty(const wxGridCellCoords
& coords
);
1362 Must be overridden to implement accessing the table values as text.
1364 virtual wxString
GetValue(int row
, int col
) = 0;
1367 Must be overridden to implement setting the table values as text.
1369 virtual void SetValue(int row
, int col
, const wxString
& value
) = 0;
1372 Returns the type of the value in the given cell.
1374 By default all cells are strings and this method returns
1375 @c wxGRID_VALUE_STRING.
1377 virtual wxString
GetTypeName(int row
, int col
);
1380 Returns true if the value of the given cell can be accessed as if it
1381 were of the specified type.
1383 By default the cells can only be accessed as strings. Note that a cell
1384 could be accessible in different ways, e.g. a numeric cell may return
1385 @true for @c wxGRID_VALUE_NUMBER but also for @c wxGRID_VALUE_STRING
1386 indicating that the value can be coerced to a string form.
1388 virtual bool CanGetValueAs(int row
, int col
, const wxString
& typeName
);
1391 Returns true if the value of the given cell can be set as if it were of
1394 @see CanGetValueAs()
1396 virtual bool CanSetValueAs(int row
, int col
, const wxString
& typeName
);
1399 Returns the value of the given cell as a long.
1401 This should only be called if CanGetValueAs() returns @true when called
1402 with @c wxGRID_VALUE_NUMBER argument. Default implementation always
1405 virtual long GetValueAsLong(int row
, int col
);
1408 Returns the value of the given cell as a double.
1410 This should only be called if CanGetValueAs() returns @true when called
1411 with @c wxGRID_VALUE_FLOAT argument. Default implementation always
1414 virtual double GetValueAsDouble(int row
, int col
);
1417 Returns the value of the given cell as a boolean.
1419 This should only be called if CanGetValueAs() returns @true when called
1420 with @c wxGRID_VALUE_BOOL argument. Default implementation always
1423 virtual bool GetValueAsBool(int row
, int col
);
1426 Returns the value of the given cell as a user-defined type.
1428 This should only be called if CanGetValueAs() returns @true when called
1429 with @a typeName. Default implementation always return @NULL.
1431 virtual void *GetValueAsCustom(int row
, int col
, const wxString
& typeName
);
1434 Sets the value of the given cell as a long.
1436 This should only be called if CanSetValueAs() returns @true when called
1437 with @c wxGRID_VALUE_NUMBER argument. Default implementation doesn't do
1440 virtual void SetValueAsLong(int row
, int col
, long value
);
1443 Sets the value of the given cell as a double.
1445 This should only be called if CanSetValueAs() returns @true when called
1446 with @c wxGRID_VALUE_FLOAT argument. Default implementation doesn't do
1449 virtual void SetValueAsDouble(int row
, int col
, double value
);
1452 Sets the value of the given cell as a boolean.
1454 This should only be called if CanSetValueAs() returns @true when called
1455 with @c wxGRID_VALUE_BOOL argument. Default implementation doesn't do
1458 virtual void SetValueAsBool( int row
, int col
, bool value
);
1461 Sets the value of the given cell as a user-defined type.
1463 This should only be called if CanSetValueAs() returns @true when called
1464 with @a typeName. Default implementation doesn't do anything.
1466 virtual void SetValueAsCustom(int row
, int col
, const wxString
& typeName
,
1473 Called by the grid when the table is associated with it.
1475 The default implementation stores the pointer and returns it from its
1476 GetView() and so only makes sense if the table cannot be associated
1477 with more than one grid at a time.
1479 virtual void SetView(wxGrid
*grid
);
1482 Returns the last grid passed to SetView().
1484 virtual wxGrid
*GetView() const;
1488 @name Table Structure Modifiers
1490 Notice that none of these functions are pure virtual as they don't have
1491 to be implemented if the table structure is never modified after
1492 creation, i.e. neither rows nor columns are never added or deleted but
1493 that you do need to implement them if they are called, i.e. if your
1494 code either calls them directly or uses the matching wxGrid methods, as
1495 by default they simply do nothing which is definitely inappropriate.
1500 Clear the table contents.
1502 This method is used by wxGrid::ClearGrid().
1504 virtual void Clear();
1507 Insert additional rows into the table.
1510 The position of the first new row.
1512 The number of rows to insert.
1514 virtual bool InsertRows(size_t pos
= 0, size_t numRows
= 1);
1517 Append additional rows at the end of the table.
1519 This method is provided in addition to InsertRows() as some data models
1520 may only support appending rows to them but not inserting them at
1521 arbitrary locations. In such case you may implement this method only
1522 and leave InsertRows() unimplemented.
1525 The number of rows to add.
1527 virtual bool AppendRows(size_t numRows
= 1);
1530 Delete rows from the table.
1532 Notice that currently deleting a row intersecting a multi-cell (see
1533 SetCellSize()) is not supported and will result in a crash.
1536 The first row to delete.
1538 The number of rows to delete.
1540 virtual bool DeleteRows(size_t pos
= 0, size_t numRows
= 1);
1543 Exactly the same as InsertRows() but for columns.
1545 virtual bool InsertCols(size_t pos
= 0, size_t numCols
= 1);
1548 Exactly the same as AppendRows() but for columns.
1550 virtual bool AppendCols(size_t numCols
= 1);
1553 Exactly the same as DeleteRows() but for columns.
1555 virtual bool DeleteCols(size_t pos
= 0, size_t numCols
= 1);
1560 @name Table Row and Column Labels
1562 By default the numbers are used for labeling rows and Latin letters for
1563 labeling columns. If the table has more than 26 columns, the pairs of
1564 letters are used starting from the 27-th one and so on, i.e. the
1565 sequence of labels is A, B, ..., Z, AA, AB, ..., AZ, BA, ..., ..., ZZ,
1571 Return the label of the specified row.
1573 virtual wxString
GetRowLabelValue(int row
);
1576 Return the label of the specified column.
1578 virtual wxString
GetColLabelValue(int col
);
1581 Set the given label for the specified row.
1583 The default version does nothing, i.e. the label is not stored. You
1584 must override this method in your derived class if you wish
1585 wxGrid::SetRowLabelValue() to work.
1587 virtual void SetRowLabelValue(int row
, const wxString
& label
);
1590 Exactly the same as SetRowLabelValue() but for columns.
1592 virtual void SetColLabelValue(int col
, const wxString
& label
);
1598 @name Attributes Management
1600 By default the attributes management is delegated to
1601 wxGridCellAttrProvider class. You may override the methods in this
1602 section to handle the attributes directly if, for example, they can be
1603 computed from the cell values.
1608 Associate this attributes provider with the table.
1610 The table takes ownership of @a attrProvider pointer and will delete it
1611 when it doesn't need it any more. The pointer can be @NULL, however
1612 this won't disable attributes management in the table but will just
1613 result in a default attributes being recreated the next time any of the
1614 other functions in this section is called. To completely disable the
1615 attributes support, should this be needed, you need to override
1616 CanHaveAttributes() to return @false.
1618 void SetAttrProvider(wxGridCellAttrProvider
*attrProvider
);
1621 Returns the attribute provider currently being used.
1623 This function may return @NULL if the attribute provider hasn't been
1624 neither associated with this table by SetAttrProvider() nor created on
1625 demand by any other methods.
1627 wxGridCellAttrProvider
*GetAttrProvider() const;
1630 Return the attribute for the given cell.
1632 By default this function is simply forwarded to
1633 wxGridCellAttrProvider::GetAttr() but it may be overridden to handle
1634 attributes directly in the table.
1636 virtual wxGridCellAttr
*GetAttr(int row
, int col
,
1637 wxGridCellAttr::wxAttrKind kind
);
1640 Set attribute of the specified cell.
1642 By default this function is simply forwarded to
1643 wxGridCellAttrProvider::SetAttr().
1645 The table takes ownership of @a attr, i.e. will call DecRef() on it.
1647 virtual void SetAttr(wxGridCellAttr
* attr
, int row
, int col
);
1650 Set attribute of the specified row.
1652 By default this function is simply forwarded to
1653 wxGridCellAttrProvider::SetRowAttr().
1655 The table takes ownership of @a attr, i.e. will call DecRef() on it.
1657 virtual void SetRowAttr(wxGridCellAttr
*attr
, int row
);
1660 Set attribute of the specified column.
1662 By default this function is simply forwarded to
1663 wxGridCellAttrProvider::SetColAttr().
1665 The table takes ownership of @a attr, i.e. will call DecRef() on it.
1667 virtual void SetColAttr(wxGridCellAttr
*attr
, int col
);
1672 Returns true if this table supports attributes or false otherwise.
1674 By default, the table automatically creates a wxGridCellAttrProvider
1675 when this function is called if it had no attribute provider before and
1678 virtual bool CanHaveAttributes();
1682 @class wxGridSizesInfo
1684 wxGridSizesInfo stores information about sizes of all wxGrid rows or
1687 It assumes that most of the rows or columns (which are both called elements
1688 here as the difference between them doesn't matter at this class level)
1689 have the default size and so stores it separately. And it uses a wxHashMap
1690 to store the sizes of all elements which have the non-default size.
1692 This structure is particularly useful for serializing the sizes of all
1693 wxGrid elements at once.
1698 struct wxGridSizesInfo
1701 Default constructor.
1703 m_sizeDefault and m_customSizes must be initialized later.
1710 This constructor is used by wxGrid::GetRowSizes() and GetColSizes()
1711 methods. User code will usually use the default constructor instead.
1714 The default element size.
1716 Array containing the sizes of @em all elements, including those
1717 which have the default size.
1719 wxGridSizesInfo(int defSize
, const wxArrayInt
& allSizes
);
1722 Get the element size.
1725 The index of the element.
1727 The size for this element, using m_customSizes if @a pos is in it
1728 or m_sizeDefault otherwise.
1730 int GetSize(unsigned pos
) const;
1737 Map with element indices as keys and their sizes as values.
1739 This map only contains the elements with non-default size.

1748 wxGrid and its related classes are used for displaying and editing tabular
1749 data. They provide a rich set of features for display, editing, and
1750 interacting with a variety of data sources. For simple applications, and to
1751 help you get started, wxGrid is the only class you need to refer to
1752 directly. It will set up default instances of the other classes and manage
1753 them for you. For more complex applications you can derive your own classes
1754 for custom grid views, grid data tables, cell editors and renderers. The
1755 @ref overview_grid has examples of simple and more complex applications,
1756 explains the relationship between the various grid classes and has a
1757 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1759 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1760 class. One or more wxGrid classes may act as a view for one table class.
1761 The default table class is called wxGridStringTable and holds an array of
1762 strings. An instance of such a class is created by CreateGrid().
1764 wxGridCellRenderer is the abstract base class for rendering contents in a
1765 cell. The following renderers are predefined:
1767 - wxGridCellBoolRenderer
1768 - wxGridCellFloatRenderer
1769 - wxGridCellNumberRenderer
1770 - wxGridCellStringRenderer
1772 The look of a cell can be further defined using wxGridCellAttr. An object
1773 of this type may be returned by wxGridTableBase::GetAttr().
1775 wxGridCellEditor is the abstract base class for editing the value of a
1776 cell. The following editors are predefined:
1778 - wxGridCellBoolEditor
1779 - wxGridCellChoiceEditor
1780 - wxGridCellFloatEditor
1781 - wxGridCellNumberEditor
1782 - wxGridCellTextEditor
1784 Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and
1785 wxGridEditorCreatedEvent for the documentation of all event types you can

1793 class wxGrid
: public wxScrolledWindow
1798 Different selection modes supported by the grid.
1800 enum wxGridSelectionModes
1803 The default selection mode allowing selection of the individual
1804 cells as well as of the entire rows and columns.
1809 The selection mode allowing the selection of the entire rows only.
1811 The user won't be able to select any cells or columns in this mode.
1816 The selection mode allowing the selection of the entire columns only.
1818 The user won't be able to select any cells or rows in this mode.
1820 wxGridSelectColumns
,
1823 The selection mode allowing the user to select either the entire
1824 columns or the entire rows but not individual cells nor blocks.
1826 Notice that while this constant is defined as @code
1827 wxGridSelectColumns | wxGridSelectRows @endcode this doesn't mean
1828 that all the other combinations are valid -- at least currently
1833 wxGridSelectRowsOrColumns
1837 Return values for GetCellSize().

1898 @name Constructors and Initialization
1903 Default constructor.
1905 You must call Create() to really create the grid window and also call
1906 CreateGrid() or SetTable() to initialize the grid contents.
1910 Constructor creating the grid window.
1912 You must call either CreateGrid() or SetTable() to initialize the grid
1913 contents before using it.
1915 wxGrid(wxWindow

1917 const wxSize
& size
= wxDefaultSize
,
1918 long style
= wxWANTS_CHARS
,
1919 const wxString
& name
= wxGridNameStr
);
1924 This will also destroy the associated grid table unless you passed a
1925 table object to the grid and specified that the grid should not take
1926 ownership of the table (see SetTable()).
1931 Creates the grid window for an object initialized using the default

1935 contents before using it.

1940 long style
= wxWANTS_CHARS
,
1941 const wxString
& name
= wxGridNameStr
);
1944 Creates a grid with the specified initial number of rows and columns.
1946 Call this directly after the grid constructor. When you use this
1947 function wxGrid will create and manage a simple table of string values
1948 for you. All of the grid data will be stored in memory.
1950 For applications with more complex data types or relationships, or for
1951 dealing with very large datasets, you should derive your own grid table
1952 class and pass a table object to the grid with SetTable().
1954 bool CreateGrid(int numRows
, int numCols
,
1955 wxGridSelectionModes selmode
= wxGridSelectCells
);
1958 Passes a pointer to a custom grid table to be used by the grid.
1960 This should be called after the grid constructor and before using the
1961 grid object. If @a takeOwnership is set to @true then the table will be
1962 deleted by the wxGrid destructor.

2181 void SetRowLabelValue(int row
, const wxString
& value
);
2184 Call this in order to make the column labels use a native look by using
2185 wxRendererNative::DrawHeaderButton() internally.
2187 There is no equivalent method for drawing row columns as there is not
2188 native look for that. This option is useful when using wxGrid for
2189 displaying tables and not as a spread-sheet.
2191 @see UseNativeColHeader()
2193 void SetUseNativeColLabels(bool native
= true);
2196 Enable the use of native header window for column labels.
2198 If this function is called with @true argument, a wxHeaderCtrl is used
2199 instead to display the column labels instead of drawing them in wxGrid
2200 code itself. This has the advantage of making the grid look and feel
2201 perfectly the same as native applications (using SetUseNativeColLabels()
2202 the grid can be made to look more natively but it still doesn't feel
2203 natively, notably the column resizing and dragging still works slightly
2204 differently as it is implemented in wxWidgets itself) but results in
2205 different behaviour for column and row headers, for which there is no
2206 equivalent function, and, most importantly, is unsuitable for grids
2207 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2208 mode. Because of this, by default the grid does not use the native
2209 header control but you should call this function to enable it if you
2210 are using the grid to display tabular data and don't have thousands of
2213 Another difference between the default behaviour and the native header
2214 behaviour is that the latter provides the user with a context menu
2215 (which appears on right clicking the header) allowing to rearrange the
2216 grid columns if CanDragColMove() returns @true. If you want to prevent
2217 this from happening for some reason, you need to define a handler for
2218 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2219 particular doesn't skip the event) as this will prevent the default
2220 right click handling from working.
2222 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2223 generated for the column labels if the native columns header is used
2224 (but this limitation could possibly be lifted in the future).

= true);

2574 Register a new data type.
2576 The data types allow to naturally associate specific renderers and
2577 editors to the cells containing values of the given type. For example,
2578 the grid automatically registers a data type with the name
2579 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
2580 wxGridCellTextEditor as its renderer and editor respectively -- this is
2581 the data type used by all the cells of the default wxGridStringTable,
2582 so this renderer and editor are used by default for all grid cells.
2584 However if a custom table returns @c wxGRID_VALUE_BOOL from its
2585 wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
2586 wxGridCellBoolEditor are used for it because the grid also registers a
2587 boolean data type with this name.
2589 And as this mechanism is completely generic, you may register your own
2590 data types using your own custom renderers and editors. Just remember
2591 that the table must identify a cell as being of the given type for them
2592 to be used for this cell.
2595 Name of the new type. May be any string, but if the type name is
2596 the same as the name of an already registered type, including one
2597 of the standard ones (which are @c wxGRID_VALUE_STRING, @c
2598 wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
2599 and @c wxGRID_VALUE_CHOICE), then the new registration information
2600 replaces the previously used renderer and editor.
2602 The renderer to use for the cells of this type. Its ownership is
2603 taken by the grid, i.e. it will call DecRef() on this pointer when
2604 it doesn't need it any longer.
2606 The editor to use for the cells of this type. Its ownership is also
2609 void RegisterDataType(const wxString

2614 Sets the value of the current grid cell to the current in-place edit
2617 This is called automatically when the grid cursor moves from the
2618 current cell to a new cell. It is also a good idea to call this
2619 function when closing a grid since any edits to the final cell location
2620 will not be saved otherwise.
2622 void SaveEditControlValue();
2625 Sets the editor for the grid cell at the specified location.

3062 make the cell at (@a row, @a col) span the block of the specified size,
3063 covering the other cells which would be normally shown in it. Passing 1

3080 Get the size of the cell in number of cells covered by it.
3082 For normal cells, the function fills both @a num_rows and @a num_cols
3083 with 1 and returns CellSpan_None. For cells which span multiple cells, i.e.
3084 for which SetCellSize() had been called, the returned values are the
3085 same ones as were passed to SetCellSize() call and the function return
3086 value is CellSpan_Main.
3088 More unexpectedly, perhaps, the returned values may be @em negative for
3089 the cells which are inside a span covered by a cell occupying multiple
3090 rows or columns. They correspond to the offset of the main cell of the
3091 span from the cell passed to this functions and the function returns
3092 CellSpan_Inside value to indicate this.
3094 As an example, consider a 3*3 grid with the cell (1, 1) (the one in the
3095 middle) having a span of 2 rows and 2 columns, i.e. the grid looks like
3105 Then the function returns 2 and 2 in @a num_rows and @a num_cols for
3106 the cell (1, 1) itself and -1 and -1 for the cell (2, 2) as well as -1
3107 and 0 for the cell (2, 1).
3110 The row of the cell.
3112 The column of the cell.

3137 @name User-Resizing and Dragging
3139 Functions controlling various interactive mouse operations.
3141 By default, columns and rows can be resized by dragging the edges of
3142 their labels (this can be disabled using DisableDragColSize() and
3143 DisableDragRowSize() methods). And if grid line dragging is enabled with
3144 EnableDragGridSize() they can also be resized by dragging the right or
3145 bottom edge of the grid cells.
3147 Columns can also be moved to interactively change their order but this
3148 needs to be explicitly enabled with EnableDragColMove().
3153 Return @true if the dragging of cells is enabled or @false otherwise.

3196 Notice that currently there is no way to make some columns resizable in
3197 a grid where columns can't be resized by default as there doesn't seem
3198 to be any need for this in practice. There is also no way to make the
3199 column marked as fixed using this method resizable again because it is
3200 supposed that fixed columns are used for static parts of the grid and
3201 so should remain fixed during the entire grid lifetime.

3204 the program from changing the column size.

3854 Increments the grid's batch count.
3856 When the count is greater than zero repainting of the grid is
3857 suppressed. Each call to BeginBatch must be matched by a later call to
3858 EndBatch(). Code that does a lot of grid modification can be enclosed
3859 between BeginBatch() and EndBatch() calls to avoid screen flicker. The
3860 final EndBatch() call will cause the grid to be repainted.
3862 Notice that you should use wxGridUpdateLocker which ensures that there
3863 is always a matching EndBatch() call for this BeginBatch() if possible
3864 instead of calling this method directly.
3869 Clears all data in the underlying grid table and repaints the grid.

3953 Returns the number of times that BeginBatch() has been called without
3954 (yet) matching calls to EndBatch(). While the grid's batch count is
3955 greater than zero the display will not be updated.
3957 int GetBatchCount();
3960 Returns the total number of grid columns.

3974 Returns the attribute for the given cell creating one if necessary.
3976 If the cell already has an attribute, it is returned. Otherwise a new
3977 attribute is created, associated with the cell and returned. In any
3978 case the caller must call DecRef() on the returned pointer.
3980 This function may only be called if CanHaveAttributes() returns @true.
3982 wxGridCellAttr

3985 Returns a base pointer to the current table object.
3987 The returned pointer is still owned by the grid.
3989 wxGridTableBase
*GetTable() const;
3992 Inserts one or more new columns into a grid with the first new column
3993 at the specified position.
3995 Notice that inserting the columns in the grid requires grid table
3996 cooperation: when this method is called, grid object begins by
3997 requesting the underlying grid table to insert new columns. If this is
3998 successful the table notifies the grid and the grid updates the
3999 display. For a default grid (one where you have called CreateGrid())
4000 this process is automatic. If you are using a custom grid table
4001 (specified with SetTable()) then you must override
4002 wxGridTableBase::InsertCols() in your derived table class.

4037 Invalidates the cached attribute for the given cell.
4039 For efficiency reasons, wxGrid may cache the recently used attributes
4040 (currently it caches only the single most recently used one, in fact)
4041 which can result in the cell appearance not being refreshed even when
4042 the attribute returned by your custom wxGridCellAttrProvider-derived
4043 class has changed. To force the grid to refresh the cell attribute,
4044 this function may be used. Notice that calling it will not result in
4045 actually redrawing the cell, you still need to call
4046 wxWindow::RefreshRect() to invalidate the area occupied by the cell in
4047 the window to do this. Also note that you don't need to call this
4048 function if you store the attributes in wxGrid itself, i.e. use its
4049 SetAttr() and similar methods, it is only useful when using a separate
4050 custom attributes provider.

4068 The wxDC to be drawn on.
4070 The position on the wxDC where rendering should begin. If not
4071 specified drawing will begin at the wxDC MaxX() and MaxY().
4073 The size of the area on the wxDC that the rendered wxGrid should
4074 occupy. If not specified the drawing will be scaled to fit the
4075 available dc width or height. The wxGrid's aspect ratio is
4076 maintained whether or not size is specified.
4078 The top left cell of the block to be drawn. Defaults to ( 0, 0 ).

4124 @name Sorting support.
4126 wxGrid doesn't provide any support for sorting the data but it does
4127 generate events allowing the user code to sort it and supports
4128 displaying the sort indicator in the column used for sorting.
4130 To use wxGrid sorting support you need to handle wxEVT_GRID_COL_SORT
4131 event (and not veto it) and resort the data displayed in the grid. The
4132 grid will automatically update the sorting indicator on the column
4135 You can also call the functions in this section directly to update the
4136 sorting indicator. Once again, they don't do anything with the grid
4137 data, it remains your responsibility to actually sort it appropriately.
4142 Return the column in which the sorting indicator is currently
4145 Returns @c wxNOT_FOUND if sorting indicator is not currently displayed
4148 @see SetSortingColumn()
4150 int GetSortingColumn() const;
4153 Return @true if this column is currently used for sorting.
4155 @see GetSortingColumn()
4157 bool IsSortingBy(int col
) const;
4160 Return @true if the current sorting order is ascending or @false if it
4163 It only makes sense to call this function if GetSortingColumn() returns
4164 a valid column index and not @c wxNOT_FOUND.
4166 @see SetSortingColumn()
4168 bool IsSortOrderAscending() const;
4171 Set the column to display the sorting indicator in and its direction.
4174 The column to display the sorting indicator in or @c wxNOT_FOUND to
4175 remove any currently displayed sorting indicator.
4177 If @true, display the ascending sort indicator, otherwise display
4178 the descending sort indicator.
4180 @see GetSortingColumn(), IsSortOrderAscending()
4182 void SetSortingColumn(int col
, bool ascending
= true);
4185 Remove any currently shown sorting indicator.
4187 This is equivalent to calling SetSortingColumn() with @c wxNOT_FOUND
4190 void UnsetSortingColumn();
4195 @name Accessors for component windows.
4197 Return the various child windows of wxGrid.
4199 wxGrid is an empty parent window for 4 children representing the column
4200 labels window (top), the row labels window (left), the corner window
4201 (top left) and the main grid window. It may be necessary to use these
4202 individual windows and not the wxGrid window itself if you need to
4203 handle events for them (this can be done using wxEvtHandler::Connect()
4204 or wxWindow::PushEventHandler()) or do something else requiring the use
4205 of the correct window pointer. Notice that you should not, however,
4206 change these windows (e.g. reposition them or draw over them) because
4207 they are managed by wxGrid itself.
4212 Return the main grid window containing the grid cells.
4214 This window is always shown.
4216 wxWindow
*GetGridWindow() const;
4219 Return the row labels window.
4221 This window is not shown if the row labels were hidden using
4224 wxWindow
*GetGridRowLabelWindow() const;
4227 Return the column labels window.
4229 This window is not shown if the columns labels were hidden using
4232 Depending on whether UseNativeColHeader() was called or not this can be
4233 either a wxHeaderCtrl or a plain wxWindow. This function returns a valid
4234 window pointer in either case but in the former case you can also use
4235 GetGridColHeader() to access it if you need wxHeaderCtrl-specific
4238 wxWindow
*GetGridColLabelWindow() const;
4241 Return the window in the top left grid corner.
4243 This window is shown only of both columns and row labels are shown and
4244 normally doesn't contain anything. Clicking on it is handled by wxGrid
4245 however and can be used to select the entire grid.
4247 wxWindow
*GetGridCornerLabelWindow() const;
4250 Return the header control used for column labels display.
4252 This function can only be called if UseNativeColHeader() had been
4255 wxHeaderCtrl
*GetGridColHeader() const;
4261 Returns @true if this grid has support for cell attributes.
4263 The grid supports attributes if it has the associated table which, in
4264 turn, has attributes support, i.e. wxGridTableBase::CanHaveAttributes()
4267 bool CanHaveAttributes() const;
4270 Get the minimal width of the given column/row.
4272 The value returned by this function may be different than that returned
4273 by GetColMinimalAcceptableWidth() if SetColMinimalWidth() had been
4274 called for this column.
4276 int GetColMinimalWidth(int col
) const;
4279 Returns the coordinate of the right border specified column.
4281 int GetColRight(int col
) const;
4284 Returns the coordinate of the left border specified column.
4286 int GetColLeft(int col
) const;
4289 Returns the minimal size for the given column.
4291 The value returned by this function may be different than that returned
4292 by GetRowMinimalAcceptableHeight() if SetRowMinimalHeight() had been
4293 called for this row.
4295 int GetRowMinimalHeight(int col
) const;
4301 @class wxGridUpdateLocker
4303 This small class can be used to prevent wxGrid from redrawing during its
4304 lifetime by calling wxGrid::BeginBatch() in its constructor and
4305 wxGrid::EndBatch() in its destructor. It is typically used in a function
4306 performing several operations with a grid which would otherwise result in
4307 flicker. For example:
4312 m_grid = new wxGrid(this, ...);
4314 wxGridUpdateLocker noUpdates(m_grid);
4315 m_grid-AppendColumn();
4316 // ... many other operations with m_grid ...
4319 // destructor called, grid refreshed
4323 Using this class is easier and safer than calling wxGrid::BeginBatch() and
4324 wxGrid::EndBatch() because you don't risk missing the call the latter (due
4325 to an exception for example).
4330 class wxGridUpdateLocker
4334 Creates an object preventing the updates of the specified @a grid. The
4335 parameter could be @NULL in which case nothing is done. If @a grid is
4336 non-@NULL then the grid must exist for longer than this
4337 wxGridUpdateLocker object itself.
4339 The default constructor could be followed by a call to Create() to set
4340 the grid object later.
4342 wxGridUpdateLocker(wxGrid
* grid
= NULL
);
4345 Destructor reenables updates for the grid this object is associated
4348 ~wxGridUpdateLocker();
4351 This method can be called if the object had been constructed using the
4352 default constructor. It must not be called more than once.
4354 void Create(wxGrid
* grid
);
4362 This event class contains information about various grid events.
4364 Notice that all grid event table macros are available in two versions:
4365 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
4366 two is that the former doesn't allow to specify the grid window identifier
4367 and so takes a single parameter, the event handler, but is not suitable if
4368 there is more than one grid control in the window where the event table is
4369 used (as it would catch the events from all the grids). The version with @c
4370 CMD takes the id as first argument and the event handler as the second one
4371 and so can be used with multiple grids as well. Otherwise there are no
4372 difference between the two and only the versions without the id are
4373 documented below for brevity.
4375 @beginEventTable{wxGridEvent}
4376 @event{EVT_GRID_CELL_CHANGING(func)}
4377 The user is about to change the data in a cell. The new cell value as
4378 string is available from GetString() event object method. This event
4379 can be vetoed if the change is not allowed.
4380 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
4381 @event{EVT_GRID_CELL_CHANGED(func)}
4382 The user changed the data in a cell. The old cell value as string is
4383 available from GetString() event object method. Notice that vetoing
4384 this event still works for backwards compatibility reasons but any new
4385 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4386 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4387 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4388 The user clicked a cell with the left mouse button. Processes a
4389 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4390 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
4391 The user double-clicked a cell with the left mouse button. Processes a
4392 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
4393 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
4394 The user clicked a cell with the right mouse button. Processes a
4395 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
4396 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
4397 The user double-clicked a cell with the right mouse button. Processes a

4400 The editor for a cell was hidden. Processes a
4401 @c wxEVT_GRID_EDITOR_HIDDEN event type.
4402 @event{EVT_GRID_EDITOR_SHOWN(func)}
4403 The editor for a cell was shown. Processes a
4404 @c wxEVT_GRID_EDITOR_SHOWN event type.
4405 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
4406 The user clicked a label with the left mouse button. Processes a
4407 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4408 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4409 The user double-clicked a label with the left mouse button. Processes a
4410 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4411 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4412 The user clicked a label with the right mouse button. Processes a
4413 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4414 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4415 The user double-clicked a label with the right mouse button. Processes
4416 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4417 @event{EVT_GRID_SELECT_CELL(func)}
4418 The given cell was made current, either by user or by the program via a
4419 call to SetGridCursor() or GoToCell(). Processes a
4420 @c wxEVT_GRID_SELECT_CELL event type.
4421 @event{EVT_GRID_COL_MOVE(func)}
4422 The user tries to change the order of the columns in the grid by
4423 dragging the column specified by GetCol(). This event can be vetoed to
4424 either prevent the user from reordering the column change completely
4425 (but notice that if you don't want to allow it at all, you simply
4426 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4427 but handled in some way in the handler, e.g. by really moving the
4428 column to the new position at the associated table level, or allowed to
4429 proceed in which case wxGrid::SetColPos() is used to reorder the
4430 columns display order without affecting the use of the column indices
4432 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4433 @event{EVT_GRID_COL_SORT(func)}
4434 This event is generated when a column is clicked by the user and its
4435 name is explained by the fact that the custom reaction to a click on a
4436 column is to sort the grid contents by this column. However the grid
4437 itself has no special support for sorting and it's up to the handler of
4438 this event to update the associated table. But if the event is handled
4439 (and not vetoed) the grid supposes that the table was indeed resorted
4440 and updates the column to indicate the new sort order and refreshes
4442 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
