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.

34 Draw the given cell on the provided DC inside the given rectangle using
35 the style specified by the attribute and the default or selected state
36 corresponding to the isSelected value.
38 This pure virtual function has a default implementation which will
39 prepare the DC using the given attribute: it will draw the rectangle
40 with the background colour from attr and set the text colour and font.

165 @class wxGridCellEditor
167 This class is responsible for providing and manipulating the in-place edit
168 controls for the grid. Instances of wxGridCellEditor (actually, instances
169 of derived classes since it is an abstract class) can be associated with
170 the cell attributes for individual cells, rows, columns, or even for the
176 @see wxGridCellBoolEditor, wxGridCellChoiceEditor, wxGridCellFloatEditor,
177 wxGridCellNumberEditor, wxGridCellTextEditor
179 class wxGridCellEditor
188 Fetch the value from the table and prepare the edit control to begin
191 This function should save the original value of the grid cell at the
192 given @a row and @a col and show the control allowing the user to
197 virtual void BeginEdit(int row
, int col
, wxGrid
* grid
) = 0;
200 Create a new object which is the copy of this one.

* parent
, wxWindowID id
,
208 wxEvtHandler
* evtHandler
) = 0;
213 virtual void Destroy();
216 End editing the cell.
218 This function must check if the current value of the editing control is
219 valid and different from the original value (available as @a oldval in
220 its string form and possibly saved internally using its real type by
221 BeginEdit()). If it isn't, it just returns @false, otherwise it fills
222 @a newval with the representation of the new value in the string form,
223 if necessary saves it using its real type internally, and returns @true.
225 If the user-defined wxEVT_GRID_CELL_CHANGING event handler doesn't veto
226 this change, ApplyEdit() will be called next.
228 virtual bool EndEdit(const wxString
& oldval
, wxString

) = 0;
231 Effectively save the changes in the grid.
233 This function should save the value of the control in the grid. It is
234 called only after EndEdit() returns @true.

239 Some types of controls on some platforms may need some help with the
242 virtual void HandleReturn(wxKeyEvent
& event
);
245 Returns @true if the edit control has been created.
250 Draws the part of the cell not occupied by the control: the base class
251 version just fills it with background colour from the attribute.
253 virtual void PaintBackground(const wxRect
& rectCell
, wxGridCellAttr

);
256 Reset the value in the control back to its starting value.
258 virtual void Reset() = 0;
261 Size and position the edit control.
263 virtual void SetSize(const wxRect

267 colours/fonts for it.

272 If the editor is enabled by clicking on the cell, this method will be
275 virtual void StartingClick();
278 If the editor is enabled by pressing keys on the grid, this will be
279 called to let the editor do something about that first key if desired.
281 virtual void StartingKey(wxKeyEvent

318 This method allows you to customize the values returned by GetValue()
319 for the cell using this editor. By default, the default values of the

621 @class wxGridTableBase
623 The almost abstract base class for grid tables.
625 A grid table is responsible for storing the grid data and, indirectly, grid
626 cell attributes. The data can be stored in the way most convenient for the
627 application but has to be provided in string form to wxGrid. It is also
628 possible to provide cells values in other formats if appropriate, e.g. as
631 This base class is not quite abstract as it implements a trivial strategy
632 for storing the attributes by forwarding it to wxGridCellAttrProvider and
633 also provides stubs for some other functions. However it does have a number
634 of pure virtual methods which must be implemented in the derived classes.
636 @see wxGridStringTable
641 class wxGridTableBase
: public wxObject
650 Destructor frees the attribute provider if it was created.
652 virtual ~wxGridTableBase();
655 Must be overridden to return the number of rows in the table.
657 For backwards compatibility reasons, this method is not const.
658 Use GetRowsCount() instead of it in const methods of derived table
661 virtual int GetNumberRows() = 0;
664 Must be overridden to return the number of columns in the table.
666 For backwards compatibility reasons, this method is not const.
667 Use GetColsCount() instead of it in const methods of derived table
670 virtual int GetNumberCols() = 0;
673 Return the number of rows in the table.
675 This method is not virtual and is only provided as a convenience for
676 the derived classes which can't call GetNumberRows() without a
677 @c const_cast from their const methods.
679 int GetRowsCount() const;
682 Return the number of columns in the table.
684 This method is not virtual and is only provided as a convenience for
685 the derived classes which can't call GetNumberCols() without a
686 @c const_cast from their const methods.
688 int GetColsCount() const;
692 @name Table Cell Accessors
697 May be overridden to implement testing for empty cells.
699 This method is used by the grid to test if the given cell is not used
700 and so whether a neighbouring cell may overflow into it. By default it
701 only returns true if the value of the given cell, as returned by
702 GetValue(), is empty.
704 virtual bool IsEmptyCell(int row
, int col
);
707 Same as IsEmptyCell() but taking wxGridCellCoords.
709 Notice that this method is not virtual, only IsEmptyCell() should be
712 bool IsEmpty(const wxGridCellCoords
& coords
);
715 Must be overridden to implement accessing the table values as text.
717 virtual wxString
GetValue(int row
, int col
) = 0;
720 Must be overridden to implement setting the table values as text.
722 virtual void SetValue(int row
, int col
, const wxString
& value
) = 0;
725 Returns the type of the value in the given cell.
727 By default all cells are strings and this method returns
728 @c wxGRID_VALUE_STRING.
730 virtual wxString
GetTypeName(int row
, int col
);
733 Returns true if the value of the given cell can be accessed as if it
734 were of the specified type.
736 By default the cells can only be accessed as strings. Note that a cell
737 could be accessible in different ways, e.g. a numeric cell may return
738 @true for @c wxGRID_VALUE_NUMBER but also for @c wxGRID_VALUE_STRING
739 indicating that the value can be coerced to a string form.
741 virtual bool CanGetValueAs(int row
, int col
, const wxString
& typeName
);
744 Returns true if the value of the given cell can be set as if it were of
749 virtual bool CanSetValueAs(int row
, int col
, const wxString
& typeName
);
752 Returns the value of the given cell as a long.
754 This should only be called if CanGetValueAs() returns @true when called
755 with @c wxGRID_VALUE_NUMBER argument. Default implementation always
758 virtual long GetValueAsLong(int row
, int col
);
761 Returns the value of the given cell as a double.
763 This should only be called if CanGetValueAs() returns @true when called
764 with @c wxGRID_VALUE_FLOAT argument. Default implementation always
767 virtual double GetValueAsDouble(int row
, int col
);
770 Returns the value of the given cell as a boolean.
772 This should only be called if CanGetValueAs() returns @true when called
773 with @c wxGRID_VALUE_BOOL argument. Default implementation always
776 virtual bool GetValueAsBool(int row
, int col
);
779 Returns the value of the given cell as a user-defined type.
781 This should only be called if CanGetValueAs() returns @true when called
782 with @a typeName. Default implementation always return @NULL.
784 virtual void *GetValueAsCustom(int row
, int col
, const wxString
& typeName
);
787 Sets the value of the given cell as a long.
789 This should only be called if CanSetValueAs() returns @true when called
790 with @c wxGRID_VALUE_NUMBER argument. Default implementation doesn't do
793 virtual void SetValueAsLong(int row
, int col
, long value
);
796 Sets the value of the given cell as a double.
798 This should only be called if CanSetValueAs() returns @true when called
799 with @c wxGRID_VALUE_FLOAT argument. Default implementation doesn't do
802 virtual void SetValueAsDouble(int row
, int col
, double value
);
805 Sets the value of the given cell as a boolean.
807 This should only be called if CanSetValueAs() returns @true when called
808 with @c wxGRID_VALUE_BOOL argument. Default implementation doesn't do
811 virtual void SetValueAsBool( int row
, int col
, bool value
);
814 Sets the value of the given cell as a user-defined type.
816 This should only be called if CanSetValueAs() returns @true when called
817 with @a typeName. Default implementation doesn't do anything.
819 virtual void SetValueAsCustom(int row
, int col
, const wxString
& typeName
,
826 Called by the grid when the table is associated with it.
828 The default implementation stores the pointer and returns it from its
829 GetView() and so only makes sense if the table cannot be associated
830 with more than one grid at a time.
832 virtual void SetView(wxGrid
*grid
);
835 Returns the last grid passed to SetView().
837 virtual wxGrid
*GetView() const;
841 @name Table Structure Modifiers
843 Notice that none of these functions are pure virtual as they don't have
844 to be implemented if the table structure is never modified after
845 creation, i.e. neither rows nor columns are never added or deleted but
846 that you do need to implement them if they are called, i.e. if your
847 code either calls them directly or uses the matching wxGrid methods, as
848 by default they simply do nothing which is definitely inappropriate.
853 Clear the table contents.
855 This method is used by wxGrid::ClearGrid().
857 virtual void Clear();
860 Insert additional rows into the table.
863 The position of the first new row.
865 The number of rows to insert.
867 virtual bool InsertRows(size_t pos
= 0, size_t numRows
= 1);
870 Append additional rows at the end of the table.
872 This method is provided in addition to InsertRows() as some data models
873 may only support appending rows to them but not inserting them at
874 arbitrary locations. In such case you may implement this method only
875 and leave InsertRows() unimplemented.
878 The number of rows to add.
880 virtual bool AppendRows(size_t numRows
= 1);
883 Delete rows from the table.
886 The first row to delete.
888 The number of rows to delete.
890 virtual bool DeleteRows(size_t pos
= 0, size_t numRows
= 1);
893 Exactly the same as InsertRows() but for columns.
895 virtual bool InsertCols(size_t pos
= 0, size_t numCols
= 1);
898 Exactly the same as AppendRows() but for columns.
900 virtual bool AppendCols(size_t numCols
= 1);
903 Exactly the same as DeleteRows() but for columns.
905 virtual bool DeleteCols(size_t pos
= 0, size_t numCols
= 1);
910 @name Table Row and Column Labels
912 By default the numbers are used for labeling rows and Latin letters for
913 labeling columns. If the table has more than 26 columns, the pairs of
914 letters are used starting from the 27-th one and so on, i.e. the
915 sequence of labels is A, B, ..., Z, AA, AB, ..., AZ, BA, ..., ..., ZZ,
921 Return the label of the specified row.
923 virtual wxString
GetRowLabelValue(int row
);
926 Return the label of the specified column.
928 virtual wxString
GetColLabelValue(int col
);
931 Set the given label for the specified row.
933 The default version does nothing, i.e. the label is not stored. You
934 must override this method in your derived class if you wish
935 wxGrid::SetRowLabelValue() to work.
937 virtual void SetRowLabelValue(int row
, const wxString
& label
);
940 Exactly the same as SetRowLabelValue() but for columns.
942 virtual void SetColLabelValue(int col
, const wxString
& label
);
948 @name Attributes Management
950 By default the attributes management is delegated to
951 wxGridCellAttrProvider class. You may override the methods in this
952 section to handle the attributes directly if, for example, they can be
953 computed from the cell values.
958 Associate this attributes provider with the table.
960 The table takes ownership of @a attrProvider pointer and will delete it
961 when it doesn't need it any more. The pointer can be @NULL, however
962 this won't disable attributes management in the table but will just
963 result in a default attributes being recreated the next time any of the
964 other functions in this section is called. To completely disable the
965 attributes support, should this be needed, you need to override
966 CanHaveAttributes() to return @false.
968 void SetAttrProvider(wxGridCellAttrProvider
*attrProvider
);
971 Returns the attribute provider currently being used.
973 This function may return @NULL if the attribute provider hasn't been
974 neither associated with this table by SetAttrProvider() nor created on
975 demand by any other methods.
977 wxGridCellAttrProvider
*GetAttrProvider() const;
980 Return the attribute for the given cell.
982 By default this function is simply forwarded to
983 wxGridCellAttrProvider::GetAttr() but it may be overridden to handle
984 attributes directly in the table.
986 virtual wxGridCellAttr
*GetAttr(int row
, int col
,
987 wxGridCellAttr::wxAttrKind kind
);
990 Set attribute of the specified cell.
992 By default this function is simply forwarded to
993 wxGridCellAttrProvider::SetAttr().
995 The table takes ownership of @a attr, i.e. will call DecRef() on it.
997 virtual void SetAttr(wxGridCellAttr
* attr
, int row
, int col
);
1000 Set attribute of the specified row.
1002 By default this function is simply forwarded to
1003 wxGridCellAttrProvider::SetRowAttr().
1005 The table takes ownership of @a attr, i.e. will call DecRef() on it.
1007 virtual void SetRowAttr(wxGridCellAttr
*attr
, int row
);
1010 Set attribute of the specified column.
1012 By default this function is simply forwarded to
1013 wxGridCellAttrProvider::SetColAttr().
1015 The table takes ownership of @a attr, i.e. will call DecRef() on it.
1017 virtual void SetColAttr(wxGridCellAttr
*attr
, int col
);
1022 Returns true if this table supports attributes or false otherwise.
1024 By default, the table automatically creates a wxGridCellAttrProvider
1025 when this function is called if it had no attribute provider before and
1028 virtual bool CanHaveAttributes();
1032 @class wxGridSizesInfo
1034 wxGridSizesInfo stores information about sizes of all wxGrid rows or
1037 It assumes that most of the rows or columns (which are both called elements
1038 here as the difference between them doesn't matter at this class level)
1039 have the default size and so stores it separately. And it uses a wxHashMap
1040 to store the sizes of all elements which have the non-default size.
1042 This structure is particularly useful for serializing the sizes of all

1098 wxGrid and its related classes are used for displaying and editing tabular
1099 data. They provide a rich set of features for display, editing, and
1100 interacting with a variety of data sources. For simple applications, and to
1101 help you get started, wxGrid is the only class you need to refer to
1102 directly. It will set up default instances of the other classes and manage
1103 them for you. For more complex applications you can derive your own classes
1104 for custom grid views, grid data tables, cell editors and renderers. The
1105 @ref overview_grid has examples of simple and more complex applications,
1106 explains the relationship between the various grid classes and has a
1107 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1109 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1110 class. One or more wxGrid classes may act as a view for one table class.
1111 The default table class is called wxGridStringTable and holds an array of
1112 strings. An instance of such a class is created by CreateGrid().
1114 wxGridCellRenderer is the abstract base class for rendereing contents in a
1115 cell. The following renderers are predefined:
1117 - wxGridCellBoolRenderer
1118 - wxGridCellFloatRenderer
1119 - wxGridCellNumberRenderer
1120 - wxGridCellStringRenderer
1122 The look of a cell can be further defined using wxGridCellAttr. An object
1123 of this type may be returned by wxGridTableBase::GetAttr().
1125 wxGridCellEditor is the abstract base class for editing the value of a
1126 cell. The following editors are predefined:
1128 - wxGridCellBoolEditor
1129 - wxGridCellChoiceEditor
1130 - wxGridCellFloatEditor
1131 - wxGridCellNumberEditor
1132 - wxGridCellTextEditor
1134 Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and
1135 wxGridEditorCreatedEvent for the documentation of all event types you can
1141 @see @ref overview_grid, wxGridUpdateLocker
1143 class wxGrid
: public wxScrolledWindow
1148 Different selection modes supported by the grid.
1150 enum wxGridSelectionModes
1153 The default selection mode allowing selection of the individual
1154 cells as well as of the entire rows and columns.
1159 The selection mode allowing the selection of the entire rows only.
1161 The user won't be able to select any cells or columns in this mode.
1166 The selection mode allowing the selection of the entire columns only.
1168 The user won't be able to select any cells or rows in this mode.
1175 @name Constructors and Initialization
1180 Default constructor.
1182 You must call Create() to really create the grid window and also call
1183 CreateGrid() or SetTable() to initialize the grid contents.
1187 Constructor creating the grid window.
1189 You must call either CreateGrid() or SetTable() to initialize the grid
1190 contents before using it.

1201 This will also destroy the associated grid table unless you passed a
1202 table object to the grid and specified that the grid should not take
1203 ownership of the table (see SetTable()).

1221 Creates a grid with the specified initial number of rows and columns.
1223 Call this directly after the grid constructor. When you use this
1224 function wxGrid will create and manage a simple table of string values
1225 for you. All of the grid data will be stored in memory.
1227 For applications with more complex data types or relationships, or for
1228 dealing with very large datasets, you should derive your own grid table
1229 class and pass a table object to the grid with SetTable().
1231 bool CreateGrid(int numRows
, int numCols
,
1232 wxGridSelectionModes selmode
= wxGridSelectCells
);
1235 Passes a pointer to a custom grid table to be used by the grid.
1237 This should be called after the grid constructor and before using the
1238 grid object. If @a takeOwnership is set to @true then the table will be
1239 deleted by the wxGrid destructor.
1241 Use this function instead of CreateGrid() when your application
1242 involves complex or non-string data or data sets that are too large to
1243 fit wholly in memory.
1245 bool SetTable(wxGridTableBase

1252 @name Grid Line Formatting
1257 Turns the drawing of grid lines on or off.
1259 void EnableGridLines(bool enable

1325 @name Label Values and Formatting
1330 Sets the arguments to the current column label alignment values.
1332 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1333 or @c wxALIGN_RIGHT.

1357 Returns the colour used for the background of row and column labels.
1359 wxColour
GetLabelBackgroundColour() const;
1362 Returns the font used for row and column labels.
1364 wxFont
GetLabelFont() const;
1367 Returns the colour used for row and column label text.
1369 wxColour
GetLabelTextColour() const;
1372 Returns the alignment used for row labels.
1374 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1375 or @c wxALIGN_RIGHT.
1377 Vertical alignment will be one of @c wxALIGN_TOP, @c wxALIGN_CENTRE or
1380 void GetRowLabelAlignment(int* horiz
, int* vert
) const;
1383 Returns the specified row label.
1385 The default grid table class provides numeric row labels. If you are
1386 using a custom grid table you can override
1387 wxGridTableBase::GetRowLabelValue() to provide your own labels.
1389 wxString
GetRowLabelValue(int row
) const;
1392 Hides the column labels by calling SetColLabelSize() with a size of 0.
1393 Show labels again by calling that method with a width greater than 0.

1398 Hides the row labels by calling SetRowLabelSize() with a size of 0.
1400 The labels can be shown again by calling SetRowLabelSize() with a width
1403 void HideRowLabels();
1406 Sets the horizontal and vertical alignment of column label text.
1408 Horizontal alignment should be one of @c wxALIGN_LEFT,
1409 @c wxALIGN_CENTRE or @c wxALIGN_RIGHT. Vertical alignment should be one
1410 of @c wxALIGN_TOP, @c wxALIGN_CENTRE or @c wxALIGN_BOTTOM.
1412 void SetColLabelAlignment(int horiz
, int vert
);
1415 Sets the orientation of the column labels (either @c wxHORIZONTAL or
1418 void SetColLabelTextOrientation(int textOrientation
);
1421 Set the value for the given column label.
1423 If you are using a custom grid table you must override
1424 wxGridTableBase::SetColLabelValue() for this to have any effect.
1426 void SetColLabelValue(int col

1447 @c wxALIGN_CENTRE or @c wxALIGN_RIGHT. Vertical alignment should be one
1448 of @c wxALIGN_TOP, @c wxALIGN_CENTRE or @c wxALIGN_BOTTOM.
1450 void SetRowLabelAlignment(int horiz
, int vert
);
1453 Sets the value for the given row label.
1455 If you are using a derived grid table you must override
1456 wxGridTableBase::SetRowLabelValue() for this to have any effect.
1458 void SetRowLabelValue(int row
, const wxString
& value
);
1461 Call this in order to make the column labels use a native look by using
1462 wxRendererNative::DrawHeaderButton() internally.
1464 There is no equivalent method for drawing row columns as there is not
1465 native look for that. This option is useful when using wxGrid for
1466 displaying tables and not as a spread-sheet.
1468 @see UseNativeColHeader()
1470 void SetUseNativeColLabels(bool native
= true);
1473 Enable the use of native header window for column labels.
1475 If this function is called with @true argument, a wxHeaderCtrl is used
1476 instead to display the column labels instead of drawing them in wxGrid
1477 code itself. This has the advantage of making the grid look and feel
1478 perfectly the same as native applications (using SetUseNativeColLabels()
1479 the grid can be made to look more natively but it still doesn't feel
1480 natively, notably the column resizing and dragging still works slightly
1481 differently as it is implemented in wxWidgets itself) but results in
1482 different behaviour for column and row headers, for which there is no
1483 equivalent function, and, most importantly, is unsuitable for grids
1484 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
1485 mode. Because of this, by default the grid does not use the native
1486 header control but you should call this function to enable it if you
1487 are using the grid to display tabular data and don't have thousands of
1490 Also note that currently @c wxEVT_GRID_LABEL_LEFT_DCLICK and
1491 @c wxEVT_GRID_LABEL_RIGHT_DCLICK events are not generated for the column
1492 labels if the native columns header is used (but this limitation could
1493 possibly be lifted in the future).

= true);
1501 @name Cell Formatting
1503 Note that wxGridCellAttr can be used alternatively to most of these
1504 methods. See the "Attributes Management" of wxGridTableBase.
1509 Sets the arguments to the horizontal and vertical text alignment values
1510 for the grid cell at the specified location.
1512 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE

1640 methods. See the "Attributes Management" of wxGridTableBase.
1645 Returns @true if the in-place edit control for the current grid cell
1646 can be used and @false otherwise.
1648 This function always returns @false for the read-only cells.
1650 bool CanEnableCellControl() const;
1653 Disables in-place editing of grid cells.
1655 Equivalent to calling EnableCellEditControl(@false).
1657 void DisableCellEditControl();
1660 Enables or disables in-place editing of grid cell data.
1662 The grid will issue either a @c wxEVT_GRID_EDITOR_SHOWN or
1663 @c wxEVT_GRID_EDITOR_HIDDEN event.
1665 void EnableCellEditControl(bool enable
= true);
1668 Makes the grid globally editable or read-only.
1670 If the edit argument is @false this function sets the whole grid as
1671 read-only. If the argument is @true the grid is set to the default
1672 state where cells may be editable. In the default state you can set
1673 single grid cells and whole rows and columns to be editable or
1674 read-only via wxGridCellAttr::SetReadOnly(). For single cells you
1675 can also use the shortcut function SetReadOnly().

1706 For simple applications where a grid object automatically uses a
1707 default grid table of string values you use this function together with
1708 SetCellValue() to access cell values. For more complex applications
1709 where you have derived your own grid table class that contains various
1710 data types (e.g. numeric, boolean or user-defined custom types) then

1843 Register a new data type.
1845 The data types allow to naturally associate specific renderers and
1846 editors to the cells containing values of the given type. For example,
1847 the grid automatically registers a data type with the name
1848 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
1849 wxGridCellTextEditor as its renderer and editor respectively -- this is
1850 the data type used by all the cells of the default wxGridStringTable,
1851 so this renderer and editor are used by default for all grid cells.
1853 However if a custom table returns @c wxGRID_VALUE_BOOL from its
1854 wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
1855 wxGridCellBoolEditor are used for it because the grid also registers a
1856 boolean data type with this name.
1858 And as this mechanism is completely generic, you may register your own
1859 data types using your own custom renderers and editors. Just remember
1860 that the table must identify a cell as being of the given type for them
1861 to be used for this cell.
1864 Name of the new type. May be any string, but if the type name is
1865 the same as the name of an already registered type, including one
1866 of the standard ones (which are @c wxGRID_VALUE_STRING, @c
1867 wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
1868 and @c wxGRID_VALUE_CHOICE), then the new registration information

1883 Sets the value of the current grid cell to the current in-place edit
1886 This is called automatically when the grid cursor moves from the
1887 current cell to a new cell. It is also a good idea to call this
1888 function when closing a grid since any edits to the final cell location
1889 will not be saved otherwise.

1970 This method provides an alternative to defining a custom grid table
1971 which would return @a typeName from its GetTypeName() method for the

2876 The x position to evaluate.
2878 If @true, rather than returning @c wxNOT_FOUND, it returns either
2879 the first or last column depending on whether @a x is too far to
2880 the left or right respectively.
2882 The column index or @c wxNOT_FOUND.

2988 Increments the grid's batch count.
2990 When the count is greater than zero repainting of the grid is
2991 suppressed. Each call to BeginBatch must be matched by a later call to
2992 EndBatch(). Code that does a lot of grid modification can be enclosed
2993 between BeginBatch() and EndBatch() calls to avoid screen flicker. The
2994 final EndBatch() call will cause the grid to be repainted.
2996 Notice that you should use wxGridUpdateLocker which ensures that there
2997 is always a matching EndBatch() call for this BeginBatch() if possible
2998 instead of calling this method directly.
3003 Clears all data in the underlying grid table and repaints the grid.
3005 The table is not deleted by this function. If you are using a derived
3006 table class then you need to override wxGridTableBase::Clear() for this
3007 function to have any effect.

3087 Returns the number of times that BeginBatch() has been called without
3088 (yet) matching calls to EndBatch(). While the grid's batch count is
3089 greater than zero the display will not be updated.
3091 int GetBatchCount();
3094 Returns the total number of grid columns.
3096 This is the same as the number of columns in the underlying grid table.
3098 int GetNumberCols() const;
3101 Returns the total number of grid rows.
3103 This is the same as the number of rows in the underlying grid table.
3105 int GetNumberRows() const;
3108 Returns the attribute for the given cell creating one if necessary.
3110 If the cell already has an attribute, it is returned. Otherwise a new
3111 attribute is created, associated with the cell and returned. In any
3112 case the caller must call DecRef() on the returned pointer.
3114 This function may only be called if CanHaveAttributes() returns @true.
3116 wxGridCellAttr

3123 wxGridTableBase
*GetTable() const;
3126 Inserts one or more new columns into a grid with the first new column
3127 at the specified position.
3129 Notice that inserting the columns in the grid requires grid table
3130 cooperation: when this method is called, grid object begins by
3131 requesting the underlying grid table to insert new columns. If this is
3132 successful the table notifies the grid and the grid updates the
3133 display. For a default grid (one where you have called CreateGrid())
3134 this process is automatic. If you are using a custom grid table
3135 (specified with SetTable()) then you must override
3136 wxGridTableBase::InsertCols() in your derived table class.

, int extraHeight
);
3187 Sets the cell attributes for all cells in the specified row.

3200 @name Sorting support.
3202 wxGrid doesn't provide any support for sorting the data but it does
3203 generate events allowing the user code to sort it and supports
3204 displaying the sort indicator in the column used for sorting.
3206 To use wxGrid sorting support you need to handle wxEVT_GRID_COL_SORT
3207 event (and not veto it) and resort the data displayed in the grid. The
3208 grid will automatically update the sorting indicator on the column
3211 You can also call the functions in this section directly to update the
3212 sorting indicator. Once again, they don't do anything with the grid
3213 data, it remains your responsibility to actually sort it appropriately.
3218 Return the column in which the sorting indicator is currently
3221 Returns @c wxNOT_FOUND if sorting indicator is not currently displayed
3224 @see SetSortingColumn()
3226 int GetSortingColumn() const;
3229 Return @true if this column is currently used for sorting.
3231 @see GetSortingColumn()
3233 bool IsSortingBy(int col
) const;
3236 Return @true if the current sorting order is ascending or @false if it
3239 It only makes sense to call this function if GetSortingColumn() returns
3240 a valid column index and not @c wxNOT_FOUND.
3242 @see SetSortingColumn()
3244 bool IsSortOrderAscending() const;
3247 Set the column to display the sorting indicator in and its direction.
3250 The column to display the sorting indicator in or @c wxNOT_FOUND to
3251 remove any currently displayed sorting indicator.
3253 If @true, display the ascending sort indicator, otherwise display
3254 the descending sort indicator.
3256 @see GetSortingColumn(), IsSortOrderAscending()
3258 void SetSortingColumn(int col
, bool ascending
= true);
3261 Remove any currently shown sorting indicator.
3263 This is equivalent to calling SetSortingColumn() with @c wxNOT_FOUND
3266 void UnsetSortingColumn();
3271 @name Accessors for component windows.
3273 Return the various child windows of wxGrid.
3275 wxGrid is an empty parent window for 4 children representing the column
3276 labels window (top), the row labels window (left), the corner window
3277 (top left) and the main grid window. It may be necessary to use these
3278 individual windows and not the wxGrid window itself if you need to
3279 handle events for them (this can be done using wxEvtHandler::Connect()
3280 or wxWindow::PushEventHandler()) or do something else requiring the use
3281 of the correct window pointer. Notice that you should not, however,
3282 change these windows (e.g. reposition them or draw over them) because
3283 they are managed by wxGrid itself.
3288 Return the main grid window containing the grid cells.
3290 This window is always shown.
3292 wxWindow
*GetGridWindow() const;
3295 Return the row labels window.
3297 This window is not shown if the row labels were hidden using
3300 wxWindow
*GetGridRowLabelWindow() const;
3303 Return the column labels window.
3305 This window is not shown if the columns labels were hidden using
3308 Depending on whether UseNativeColHeader() was called or not this can be
3309 either a wxHeaderCtrl or a plain wxWindow. This function returns a valid
3310 window pointer in either case but in the former case you can also use
3311 GetGridColHeader() to access it if you need wxHeaderCtrl-specific
3314 wxWindow
*GetGridColLabelWindow() const;
3317 Return the window in the top left grid corner.
3319 This window is shown only of both columns and row labels are shown and
3320 normally doesn't contain anything. Clicking on it is handled by wxGrid
3321 however and can be used to select the entire grid.
3323 wxWindow
*GetGridCornerLabelWindow() const;
3326 Return the header control used for column labels display.
3328 This function can only be called if UseNativeColHeader() had been
3331 wxHeaderCtrl
*GetGridColHeader() const;
3337 Returns @true if this grid has support for cell attributes.
3339 The grid supports attributes if it has the associated table which, in
3340 turn, has attributes support, i.e. wxGridTableBase::CanHaveAttributes()
3343 bool CanHaveAttributes() const;
3346 Get the minimal width of the given column/row.
3348 The value returned by this function may be different than that returned
3349 by GetColMinimalAcceptableWidth() if SetColMinimalWidth() had been
3350 called for this column.
3352 int GetColMinimalWidth(int col
) const;
3355 Returns the coordinate of the right border specified column.
3357 int GetColRight(int col
) const;
3360 Returns the coordinate of the left border specified column.
3362 int GetColLeft(int col
) const;
3365 Returns the minimal size for the given column.
3367 The value returned by this function may be different than that returned
3368 by GetRowMinimalAcceptableHeight() if SetRowMinimalHeight() had been
3369 called for this row.
3371 int GetRowMinimalHeight(int col
) const;
3377 @class wxGridUpdateLocker
3379 This small class can be used to prevent wxGrid from redrawing during its
3380 lifetime by calling wxGrid::BeginBatch() in its constructor and
3381 wxGrid::EndBatch() in its destructor. It is typically used in a function
3382 performing several operations with a grid which would otherwise result in
3383 flicker. For example:
3388 m_grid = new wxGrid(this, ...);
3390 wxGridUpdateLocker noUpdates(m_grid);
3391 m_grid-AppendColumn();
3392 // ... many other operations with m_grid ...
3395 // destructor called, grid refreshed
3399 Using this class is easier and safer than calling wxGrid::BeginBatch() and
3400 wxGrid::EndBatch() because you don't risk missing the call the latter (due
3401 to an exception for example).
3406 class wxGridUpdateLocker
3410 Creates an object preventing the updates of the specified @a grid. The
3411 parameter could be @NULL in which case nothing is done. If @a grid is
3412 non-@NULL then the grid must exist for longer than this
3413 wxGridUpdateLocker object itself.
3415 The default constructor could be followed by a call to Create() to set
3416 the grid object later.
3418 wxGridUpdateLocker(wxGrid
* grid
= NULL
);
3421 Destructor reenables updates for the grid this object is associated
3424 ~wxGridUpdateLocker();
3427 This method can be called if the object had been constructed using the
3428 default constructor. It must not be called more than once.
3430 void Create(wxGrid
* grid
);
3438 This event class contains information about various grid events.
3440 Notice that all grid event table macros are available in two versions:
3441 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
3442 two is that the former doesn't allow to specify the grid window identifier
3443 and so takes a single parameter, the event handler, but is not suitable if
3444 there is more than one grid control in the window where the event table is
3445 used (as it would catch the events from all the grids). The version with @c
3446 CMD takes the id as first argument and the event handler as the second one
3447 and so can be used with multiple grids as well. Otherwise there are no
3448 difference between the two and only the versions without the id are
3449 documented below for brevity.
3451 @beginEventTable{wxGridEvent}
3452 @event{EVT_GRID_CELL_CHANGING(func)}
3453 The user is about to change the data in a cell. The new cell value as
3454 string is available from GetString() event object method. This event
3455 can be vetoed if the change is not allowed.
3456 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
3457 @event{EVT_GRID_CELL_CHANGED(func)}
3458 The user changed the data in a cell. The old cell value as string is
3459 available from GetString() event object method. Notice that vetoing
3460 this event still works for backwards compatibility reasons but any new
3461 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
3462 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
3463 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
3464 The user clicked a cell with the left mouse button. Processes a
3465 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
3466 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
3467 The user double-clicked a cell with the left mouse button. Processes a
3468 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.

3476 The editor for a cell was hidden. Processes a
3477 @c wxEVT_GRID_EDITOR_HIDDEN event type.
3478 @event{EVT_GRID_EDITOR_SHOWN(func)}
3479 The editor for a cell was shown. Processes a
3480 @c wxEVT_GRID_EDITOR_SHOWN event type.
3481 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
3482 The user clicked a label with the left mouse button. Processes a
3483 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
3484 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
3485 The user double-clicked a label with the left mouse button. Processes a
3486 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
3487 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
3488 The user clicked a label with the right mouse button. Processes a
3489 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
3490 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
3491 The user double-clicked a label with the right mouse button. Processes
3492 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
3493 @event{EVT_GRID_SELECT_CELL(func)}
3494 The user moved to, and selected a cell. Processes a
3495 @c wxEVT_GRID_SELECT_CELL event type.
3496 @event{EVT_GRID_COL_MOVE(func)}
3497 The user tries to change the order of the columns in the grid by
3498 dragging the column specified by GetCol(). This event can be vetoed to
3499 either prevent the user from reordering the column change completely
3500 (but notice that if you don't want to allow it at all, you simply
3501 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
3502 but handled in some way in the handler, e.g. by really moving the
3503 column to the new position at the associated table level, or allowed to
3504 proceed in which case wxGrid::SetColPos() is used to reorder the
3505 columns display order without affecting the use of the column indices
3507 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
3508 @event{EVT_GRID_COL_SORT(func)}
3509 This event is generated when a column is clicked by the user and its
3510 name is explained by the fact that the custom reaction to a click on a
3511 column is to sort the grid contents by this column. However the grid
3512 itself has no special support for sorting and it's up to the handler of
3513 this event to update the associated table. But if the event is handled
3514 (and not vetoed) the grid supposes that the table was indeed resorted
3515 and updates the column to indicate the new sort order and refreshes
3517 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
