10 @class wxGridCellFloatRenderer
12 This class may be used to format floating point data in a cell.
17 @see wxGridCellRenderer, wxGridCellNumberRenderer, wxGridCellStringRenderer,

20 class wxGridCellFloatRenderer
: public wxGridCellStringRenderer
25 Minimum number of characters to be shown.
27 Number of digits after the decimal dot.
29 wxGridCellFloatRenderer(int width
= -1, int precision
= -1);
32 Returns the precision.
34 int GetPrecision() const;
42 Parameters string format is "width[,precision]".
44 void SetParameters(const wxString
& params
);
49 void SetPrecision(int precision
);
54 void SetWidth(int width
);
60 @class wxGridTableBase
62 The almost abstract base class for grid tables.
64 A grid table is responsible for storing the grid data and, indirectly, grid
65 cell attributes. The data can be stored in the way most convenient for the
66 application but has to be provided in string form to wxGrid. It is also
67 possible to provide cells values in other formats if appropriate, e.g. as
70 This base class is not quite abstract as it implements a trivial strategy
71 for storing the attributes by forwarding it to wxGridCellAttrProvider and
72 also provides stubs for some other functions. However it does have a number
73 of pure virtual methods which must be implemented in the derived classes.
75 @see wxGridStringTable
80 class wxGridTableBase
: public wxObject
83 /// Default constructor.
86 /// Destructor frees the attribute provider if it was created.
87 virtual ~wxGridTableBase();
90 Must be overridden to return the number of rows in the table.
92 For backwards compatibility reasons, this method is not const.
93 Use GetRowsCount() instead of it in const methods of derived table
96 virtual int GetNumberRows() = 0;
99 Must be overridden to return the number of columns in the table.
101 For backwards compatibility reasons, this method is not const.
102 Use GetColsCount() instead of it in const methods of derived table
105 virtual int GetNumberCols() = 0;
108 Return the number of rows in the table.
110 This method is not virtual and is only provided as a convenience for
111 the derived classes which can't call GetNumberRows() without a @c
112 const_cast from their const methods.
114 int GetRowsCount() const;
117 Return the number of columns in the table.
119 This method is not virtual and is only provided as a convenience for
120 the derived classes which can't call GetNumberCols() without a @c
121 const_cast from their const methods.
123 int GetColsCount() const;
127 Accessing table cells.
131 /// Must be overridden to implement testing for empty cells.
132 virtual bool IsEmptyCell(int row
, int col
) = 0;
135 Same as IsEmptyCell() but taking wxGridCellCoords.
137 Notice that this method is not virtual, only IsEmptyCell() should be
140 bool IsEmpty(const wxGridCellCoords
& coords
);
142 /// Must be overridden to implement accessing the table values as text.
143 virtual wxString
GetValue(int row
, int col
) = 0;
145 /// Must be overridden to implement setting the table values as text.
146 virtual void SetValue(int row
, int col
, const wxString
& value
) = 0;
149 Returns the type of the value in the given cell.
151 By default all cells are strings and this method returns @c
154 virtual wxString
GetTypeName(int row
, int col
);
157 Returns true if the value of the given cell can be accessed as if it
158 were of the specified type.
160 By default the cells can only be accessed as strings. Note that a cell
161 could be accessible in different ways, e.g. a numeric cell may return
162 @true for @c wxGRID_VALUE_NUMBER but also for @c wxGRID_VALUE_STRING
163 indicating that the value can be coerced to a string form.
165 virtual bool CanGetValueAs(int row
, int col
, const wxString
& typeName
);
168 Returns true if the value of the given cell can be set as if it were of
173 virtual bool CanSetValueAs(int row
, int col
, const wxString
& typeName
);
176 Returns the value of the given cell as a long.
178 This should only be called if CanGetValueAs() returns @true when called
179 with @c wxGRID_VALUE_NUMBER argument. Default implementation always
182 virtual long GetValueAsLong(int row
, int col
);
185 Returns the value of the given cell as a double.
187 This should only be called if CanGetValueAs() returns @true when called
188 with @c wxGRID_VALUE_FLOAT argument. Default implementation always
191 virtual double GetValueAsDouble(int row
, int col
);
194 Returns the value of the given cell as a boolean.
196 This should only be called if CanGetValueAs() returns @true when called
197 with @c wxGRID_VALUE_BOOL argument. Default implementation always
200 virtual bool GetValueAsBool(int row
, int col
);
203 Returns the value of the given cell as a user-defined type.
205 This should only be called if CanGetValueAs() returns @true when called
206 with @a typeName. Default implementation always return @NULL.
208 virtual void *GetValueAsCustom(int row
, int col
, const wxString
& typeName
);
212 Sets the value of the given cell as a long.
214 This should only be called if CanSetValueAs() returns @true when called
215 with @c wxGRID_VALUE_NUMBER argument. Default implementation doesn't do
218 virtual void SetValueAsLong(int row
, int col
, long value
);
221 Sets the value of the given cell as a double.
223 This should only be called if CanSetValueAs() returns @true when called
224 with @c wxGRID_VALUE_FLOAT argument. Default implementation doesn't do
227 virtual void SetValueAsDouble(int row
, int col
, double value
);
230 Sets the value of the given cell as a boolean.
232 This should only be called if CanSetValueAs() returns @true when called
233 with @c wxGRID_VALUE_BOOL argument. Default implementation doesn't do
236 virtual void SetValueAsBool( int row
, int col
, bool value
);
239 Sets the value of the given cell as a user-defined type.
241 This should only be called if CanSetValueAs() returns @true when called
242 with @a typeName. Default implementation doesn't do anything.
244 virtual void SetValueAsCustom(int row
, int col
, const wxString
& typeName
,
250 Called by the grid when the table is associated with it.
252 The default implementation stores the pointer and returns it from its
253 GetView() and so only makes sense if the table cannot be associated
254 with more than one grid at a time.
256 virtual void SetView(wxGrid
*grid
);
259 Returns the last grid passed to SetView().
261 virtual wxGrid
*GetView() const;
265 Modifying the table structure.
267 Notice that none of these functions are pure virtual as they don't have
268 to be implemented if the table structure is never modified after
269 creation, i.e. neither rows nor columns are never added or deleted but
270 that you do need to implement them if they are called, i.e. if your
271 code either calls them directly or uses the matching wxGrid methods, as
272 by default they simply do nothing which is definitely inappropriate.
277 Clear the table contents.
279 This method is used by wxGrid::ClearGrid().
281 virtual void Clear();
284 Insert additional rows into the table.
287 The position of the first new row.
289 The number of rows to insert.
291 virtual bool InsertRows(size_t pos
= 0, size_t numRows
= 1);
294 Append additional rows at the end of the table.
296 This method is provided in addition to InsertRows() as some data models
297 may only support appending rows to them but not inserting them at
298 arbitrary locations. In such case you may implement this method only
299 and leave InsertRows() unimplemented.
302 The position of the first new row.
304 The number of rows to add.
306 virtual bool AppendRows(size_t numRows
= 1);
309 Delete rows from the table.
312 The first row to delete.
314 The number of rows to delete.
316 virtual bool DeleteRows(size_t pos
= 0, size_t numRows
= 1);
318 /// Exactly the same as InsertRows() but for columns.
319 virtual bool InsertCols(size_t pos
= 0, size_t numCols
= 1);
321 /// Exactly the same as AppendRows() but for columns.
322 virtual bool AppendCols(size_t numCols
= 1);
324 /// Exactly the same as DeleteRows() but for columns.
325 virtual bool DeleteCols(size_t pos
= 0, size_t numCols
= 1);
330 Table rows and columns labels.
332 By default the numbers are used for labeling rows and Latin letters for
333 labeling columns. If the table has more than 26 columns, the pairs of
334 letters are used starting from the 27-th one and so on, i.e. the
335 sequence of labels is A, B, ..., Z, AA, AB, ..., AZ, BA, ..., ..., ZZ,
340 /// Return the label of the specified row.
341 virtual wxString
GetRowLabelValue(int row
);
343 /// Return the label of the specified column.
344 virtual wxString
GetColLabelValue(int col
);
347 Set the given label for the specified row.
349 The default version does nothing, i.e. the label is not stored. You
350 must override this method in your derived class if you wish
351 wxGrid::SetRowLabelValue() to work.
353 virtual void SetRowLabelValue(int row
, const wxString
& label
);
355 /// Exactly the same as SetRowLabelValue() but for columns.
356 virtual void SetColLabelValue(int col
, const wxString
& label
);
362 Attributes management.
364 By default the attributes management is delegated to
365 wxGridCellAttrProvider class. You may override the methods in this
366 section to handle the attributes directly if, for example, they can be
367 computed from the cell values.
372 Associate this attributes provider with the table.
374 The table takes ownership of @a attrProvider pointer and will delete it
375 when it doesn't need it any more. The pointer can be @NULL, however
376 this won't disable attributes management in the table but will just
377 result in a default attributes being recreated the next time any of the
378 other functions in this section is called. To completely disable the
379 attributes support, should this be needed, you need to override
380 CanHaveAttributes() to return @false.
382 void SetAttrProvider(wxGridCellAttrProvider
*attrProvider
);
385 Returns the attribute provider currently being used.
387 This function may return @NULL if the attribute provider hasn't been
388 neither associated with this table by SetAttrProvider() nor created on
389 demand by any other methods.
391 wxGridCellAttrProvider
*GetAttrProvider() const { return m_attrProvider
; }
394 Returns true if this table supports attributes or false otherwise.
396 By default, the table automatically creates a wxGridCellAttrProvider
397 when this function is called if it had no attribute provider before and
400 virtual bool CanHaveAttributes();
403 Return the attribute for the given cell.
405 By default this function is simply forwarded to
406 wxGridCellAttrProvider::GetAttr() but it may be overridden to handle
407 attributes directly in the table.
409 virtual wxGridCellAttr
*GetAttr(int row
, int col
,
410 wxGridCellAttr::wxAttrKind kind
);
413 Set attribute of the specified cell.
415 By default this function is simply forwarded to
416 wxGridCellAttrProvider::SetAttr().
418 The table takes ownership of @a attr, i.e. will call DecRef() on it.
420 virtual void SetAttr(wxGridCellAttr
* attr
, int row
, int col
);
423 Set attribute of the specified row.
425 By default this function is simply forwarded to
426 wxGridCellAttrProvider::SetRowAttr().
428 The table takes ownership of @a attr, i.e. will call DecRef() on it.
430 virtual void SetRowAttr(wxGridCellAttr
*attr
, int row
);
433 Set attribute of the specified column.
435 By default this function is simply forwarded to
436 wxGridCellAttrProvider::SetColAttr().
438 The table takes ownership of @a attr, i.e. will call DecRef() on it.
440 virtual void SetColAttr(wxGridCellAttr
*attr
, int col
);
448 @class wxGridCellEditor
450 This class is responsible for providing and manipulating
451 the in-place edit controls for the grid. Instances of wxGridCellEditor
452 (actually, instances of derived classes since it is an abstract class) can be
453 associated with the cell attributes for individual cells, rows, columns, or
454 even for the entire grid.
459 @see wxGridCellTextEditor, wxGridCellFloatEditor, wxGridCellBoolEditor,
460 wxGridCellNumberEditor, wxGridCellChoiceEditor
462 class wxGridCellEditor
471 The dtor is private because only DecRef() can delete us.
476 Fetch the value from the table and prepare the edit control
477 to begin editing. Set the focus to the edit control.
479 void BeginEdit(int row
, int col
, wxGrid
* grid
);
482 Create a new object which is the copy of this one.
484 wxGridCellEditor
* Clone() const;
487 Creates the actual edit control.
489 void Create(wxWindow
* parent
, wxWindowID id
,
490 wxEvtHandler
* evtHandler
);
498 Complete the editing of the current cell. Returns @true if the value has
499 changed. If necessary, the control may be destroyed.
501 bool EndEdit(int row
, int col
, wxGrid
* grid
);
504 Some types of controls on some platforms may need some help
507 void HandleReturn(wxKeyEvent
& event
);
515 Draws the part of the cell not occupied by the control: the base class
516 version just fills it with background colour from the attribute.
518 void PaintBackground(const wxRect
& rectCell
,
519 wxGridCellAttr
* attr
);
522 Reset the value in the control back to its starting value.
527 Size and position the edit control.
529 void SetSize(const wxRect
& rect
);
532 Show or hide the edit control, use the specified attributes to set
533 colours/fonts for it.
535 void Show(bool show
, wxGridCellAttr
* attr
= NULL
);
538 If the editor is enabled by clicking on the cell, this method will be
541 void StartingClick();
544 If the editor is enabled by pressing keys on the grid,
545 this will be called to let the editor do something about
546 that first key if desired.
548 void StartingKey(wxKeyEvent
& event
);

785 in the grid. You may pass it to the wxGridCellAttr (below) to change the
786 format of one given cell or to wxGrid::SetDefaultRenderer() to change the
787 view of all cells. This is an abstract class, and you will normally use one of
789 predefined derived classes or derive your own class from it.

1223 wxGrid and its related classes are used for displaying and editing tabular
1225 They provide a rich set of features for display, editing, and interacting
1226 with a variety of data sources. For simple applications, and to help you
1227 get started, wxGrid is the only class you need to refer to directly. It
1228 will set up default instances of the other classes and manage them for you.
1229 For more complex applications you can derive your own classes for custom
1230 grid views, grid data tables, cell editors and renderers. The @ref
1231 overview_gridoverview has examples of simple and more complex applications,
1232 explains the relationship between the various grid classes and has a
1233 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1235 wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards.
1236 The new grid classes are reasonably backward-compatible but there are some
1237 exceptions. There are also easier ways of doing many things compared to the
1238 previous implementation.
1240 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1241 class. One or more wxGrid classes may act as a view for one table class.
1242 The default table class is called wxGridStringTable and holds an array of
1243 strings. An instance of such a class is created by wxGrid::CreateGrid.
1245 wxGridCellRenderer is the abstract base class for rendereing contents in a
1246 cell. The following renderers are predefined:
1247 - wxGridCellStringRenderer,
1248 - wxGridCellBoolRenderer,
1249 - wxGridCellFloatRenderer,
1250 - wxGridCellNumberRenderer.
1251 The look of a cell can be further defined using wxGridCellAttr. An object
1252 of this type may be returned by wxGridTableBase::GetAttr.
1254 wxGridCellEditor is the abstract base class for editing the value of a
1255 cell. The following editors are predefined:
1256 - wxGridCellTextEditor
1257 - wxGridCellBoolEditor
1258 - wxGridCellChoiceEditor
1259 - wxGridCellNumberEditor.
1264 @see @ref overview_gridoverview "wxGrid overview"
1266 class wxGrid

1270 Different selection modes supported by the grid.
1272 enum wxGridSelectionModes
1275 The default selection mode allowing selection of the individual
1276 cells as well as of the entire rows and columns.
1281 The selection mode allowing the selection of the entire rows only.
1283 The user won't be able to select any cells or columns in this mode.

1333 This will also destroy the associated grid table unless you passed a
1334 table object to the grid and specified that the grid should not take
1335 ownership of the table (see wxGrid::SetTable).
1340 Appends one or more new columns to the right of the grid.
1342 The @a updateLabels argument is not used at present. If you are using a
1343 derived grid table class you will need to override
1344 wxGridTableBase::AppendCols. See InsertCols() for further information.
1346 @return @true on success or @false if appending columns failed.
1348 bool AppendCols(int numCols
= 1, bool updateLabels
= true);
1351 Appends one or more new rows to the bottom of the grid.
1353 The @a updateLabels argument is not used at present. If you are using a
1354 derived grid table class you will need to override
1355 wxGridTableBase::AppendRows. See InsertRows() for further information.
1357 @return @true on success or @false if appending rows failed.

);
1373 Automatically sizes the column to fit its contents. If setAsMin is @true the
1374 calculated width will
1375 also be set as the minimal width for the column.
1377 void AutoSizeColumn(int col
, bool setAsMin
= true);
1380 Automatically sizes all columns to fit their contents. If setAsMin is @true the
1381 calculated widths will
1382 also be set as the minimal widths for the columns.
1384 void AutoSizeColumns(bool setAsMin
= true);
1387 Automatically sizes the row to fit its contents. If setAsMin is @true the
1388 calculated height will
1389 also be set as the minimal height for the row.
1391 void AutoSizeRow(int row
, bool setAsMin
= true);
1394 Automatically adjusts height of the row to fit its label.
1396 void AutoSizeRowLabelSize(int col
);
1399 Automatically sizes all rows to fit their contents. If setAsMin is @true the
1400 calculated heights will
1401 also be set as the minimal heights for the rows.
1403 void AutoSizeRows(bool setAsMin
= true);
1406 Increments the grid's batch count.
1408 When the count is greater than zero repainting of the grid is
1409 suppressed. Each call to BeginBatch must be matched by a later call to
1410 EndBatch(). Code that does a lot of grid modification can be enclosed
1411 between BeginBatch and EndBatch calls to avoid screen flicker. The
1412 final EndBatch will cause the grid to be repainted.
1414 Notice that you should use wxGridUpdateLocker which ensures that there
1415 is always a matching EndBatch() call for this BeginBatch() if possible
1416 instead of calling this method directly.
1421 Convert grid cell coordinates to grid window pixel coordinates.
1423 This function returns the rectangle that encloses the block of cells
1424 limited by @a topLeft and @a bottomRight cell in device coords and
1425 clipped to the client size of the grid window.
1429 wxRect
BlockToDeviceRect(const wxGridCellCoords

1433 Returns @true if columns can be moved by dragging with the mouse.
1435 Columns can be moved by dragging on their labels.
1437 bool CanDragColMove() const;
1440 Returns @true if columns can be resized by dragging with the mouse.
1442 Columns can be resized by dragging the edges of their labels. If grid
1443 line dragging is enabled they can also be resized by dragging the right
1444 edge of the column in the grid cell area (see
1445 wxGrid::EnableDragGridSize).
1447 bool CanDragColSize() const;
1450 Return @true if the dragging of grid lines to resize rows and columns
1451 is enabled or @false otherwise.
1453 bool CanDragGridSize() const;
1456 Returns @true if rows can be resized by dragging with the mouse.
1458 Rows can be resized by dragging the edges of their labels. If grid line
1459 dragging is enabled they can also be resized by dragging the lower edge
1460 of the row in the grid cell area (see wxGrid::EnableDragGridSize).
1462 bool CanDragRowSize() const;
1465 Returns @true if the in-place edit control for the current grid cell
1466 can be used and @false otherwise.
1468 This function always returns @false for the read-only cells.
1470 bool CanEnableCellControl() const;
1473 Returns @true if this grid has support for cell attributes.
1475 The grid supports attributes if it has the associated table which, in
1476 turn, has attributes support, i.e. wxGridTableBase::CanHaveAttributes()
1479 bool CanHaveAttributes() const;
1483 Return the rectangle corresponding to the grid cell's size and position
1484 in logical coordinates.
1486 @see BlockToDeviceRect()

1494 Clears all data in the underlying grid table and repaints the grid.
1496 The table is not deleted by this function. If you are using a derived
1497 table class then you need to override wxGridTableBase::Clear() for this
1498 function to have any effect.
1503 Deselects all cells that are currently selected.
1505 void ClearSelection();
1508 Creates a grid with the specified initial number of rows and columns.
1510 Call this directly after the grid constructor. When you use this
1511 function wxGrid will create and manage a simple table of string values
1512 for you. All of the grid data will be stored in memory.
1513 For applications with more complex data types or relationships, or for
1514 dealing with very large datasets, you should derive your own grid table
1515 class and pass a table object to the grid with SetTable().
1517 bool CreateGrid(int numRows
, int numCols
,
1518 wxGridSelectionModes selmode
= wxGridSelectCells
);
1521 Deletes one or more columns from a grid starting at the specified
1524 The @a updateLabels argument is not used at present. If you are using a
1525 derived grid table class you will need to override
1526 wxGridTableBase::DeleteCols. See InsertCols() for further information.
1528 @return @true on success or @false if deleting columns failed.
1530 bool DeleteCols(int pos
= 0, int numCols
= 1, bool updateLabels
= true);
1533 Deletes one or more rows from a grid starting at the specified position.
1535 The @a updateLabels argument is not used at present. If you are using a
1536 derived grid table class you will need to override
1537 wxGridTableBase::DeleteRows. See InsertRows() for further information.
1539 @return @true on success or @false if appending rows failed.
1541 bool DeleteRows(int pos
= 0, int numRows
= 1, bool updateLabels
= true);
1544 Disables in-place editing of grid cells.
1546 Equivalent to calling EnableCellEditControl(@false).
1548 void DisableCellEditControl();
1551 Disables column moving by dragging with the mouse.
1553 Equivalent to passing @false to EnableDragColMove().
1555 void DisableDragColMove();
1558 Disables column sizing by dragging with the mouse.
1560 Equivalent to passing @false to EnableDragColSize().
1562 void DisableDragColSize();
1565 Disable mouse dragging of grid lines to resize rows and columns.
1567 Equivalent to passing @false to EnableDragGridSize()
1569 void DisableDragGridSize();
1572 Disables row sizing by dragging with the mouse.
1574 Equivalent to passing @false to EnableDragRowSize().
1576 void DisableDragRowSize();
1579 Enables or disables in-place editing of grid cell data.
1581 The grid will issue either a wxEVT_GRID_EDITOR_SHOWN or
1582 wxEVT_GRID_EDITOR_HIDDEN event.
1584 void EnableCellEditControl(bool enable
= true);
1587 Enables or disables column moving by dragging with the mouse.
1589 void EnableDragColMove(bool enable
= true);
1592 Enables or disables column sizing by dragging with the mouse.
1594 void EnableDragColSize(bool enable
= true);
1597 Enables or disables row and column resizing by dragging gridlines with the
1600 void EnableDragGridSize(bool enable
= true);
1603 Enables or disables row sizing by dragging with the mouse.
1605 void EnableDragRowSize(bool enable
= true);
1608 Makes the grid globally editable or read-only.
1610 If the edit argument is @false this function sets the whole grid as
1611 read-only. If the argument is @true the grid is set to the default
1612 state where cells may be editable. In the default state you can set
1613 single grid cells and whole rows and columns to be editable or
1614 read-only via wxGridCellAttribute::SetReadOnly. For single cells you
1615 can also use the shortcut function SetReadOnly().
1617 For more information about controlling grid cell attributes see the
1618 wxGridCellAttr cell attribute class and the
1619 @ref overview_gridoverview.
1621 void EnableEditing(bool edit
);
1624 Turns the drawing of grid lines on or off.
1626 void EnableGridLines(bool enable
= true);
1629 Decrements the grid's batch count.
1631 When the count is greater than zero repainting of the grid is
1632 suppressed. Each previous call to BeginBatch() must be matched by a
1633 later call to EndBatch. Code that does a lot of grid modification can
1634 be enclosed between BeginBatch and EndBatch calls to avoid screen
1635 flicker. The final EndBatch will cause the grid to be repainted.
1637 @see wxGridUpdateLocker
1642 Overridden wxWindow method.
1647 Causes immediate repainting of the grid.
1649 Use this instead of the usual wxWindow::Refresh.
1651 void ForceRefresh();
1654 Returns the number of times that BeginBatch() has been called
1655 without (yet) matching calls to EndBatch(). While
1656 the grid's batch count is greater than zero the display will not be updated.
1658 int GetBatchCount() const;
1661 Sets the arguments to the horizontal and vertical text alignment values
1662 for the grid cell at the specified location.
1664 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1665 or @c wxALIGN_RIGHT.

1706 wxColour
GetCellTextColour(int row
, int col
) const;
1710 Returns the string contained in the cell at the specified location.
1712 For simple applications where a grid object automatically uses a
1713 default grid table of string values you use this function together with
1714 SetCellValue() to access cell values. For more complex applications
1715 where you have derived your own grid table class that contains various
1716 data types (e.g. numeric, boolean or user-defined custom types) then
1717 you only use this function for those cells that contain string values.
1719 See wxGridTableBase::CanGetValueAs and the @ref overview_gridoverview
1720 "wxGrid overview" for more information.

2088 Please notice this behaviour is by design and is needed in order to
2089 support grids of arbitrary size (when an entire column is selected in
2090 a grid with a million of columns, we don't want to create an array with
2091 a million of entries in this function, instead it returns an empty
2092 array and GetSelectedCols() returns an array containing one element).
2094 wxGridCellCoordsArray
GetSelectedCells() const;
2097 Returns an array of selected columns.
2099 Please notice that this method alone is not sufficient to find all the
2100 selected columns as it contains only the columns which were
2101 individually selected but not those being part of the block selection
2102 or being selected in virtue of all of their cells being selected
2103 individually, please see GetSelectedCells() for more details.

2165 Make the given cell current and ensure it is visible.
2167 This method is equivalent to calling MakeCellVisible() and
2168 SetGridCursor() and so, as with the latter, a wxEVT_GRID_SELECT_CELL
2169 event is generated by it and the selected cell doesn't change if the

2202 Inserts one or more new columns into a grid with the first new column
2203 at the specified position.
2205 Notice that inserting the columns in the grid requires grid table
2206 cooperation: when this method is called, grid object begins by
2207 requesting the underlying grid table to insert new columns. If this is
2208 successful the table notifies the grid and the grid updates the
2209 display. For a default grid (one where you have called
2210 wxGrid::CreateGrid) this process is automatic. If you are using a
2211 custom grid table (specified with wxGrid::SetTable) then you must
2212 override wxGridTableBase::InsertCols() in your derived table class.

2385 bool MovePageDown();
2388 Moves the grid cursor up by some number of rows so that the previous
2389 top visible row becomes the bottom visible row.
2394 Register a new data type.
2396 The data types allow to naturally associate specific renderers and
2397 editors to the cells containing values of the given type. For example,
2398 the grid automatically registers a data type with the name @c
2399 wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
2400 wxGridCellTextEditor as its renderer and editor respectively -- this is
2401 the data type used by all the cells of the default wxGridStringTable,
2402 so this renderer and editor are used by default for all grid cells.
2404 However if a custom table returns @c wxGRID_VALUE_BOOL from its
2405 wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
2406 wxGridCellBoolEditor are used for it because the grid also registers a
2407 boolean data type with this name.
2409 And as this mechanism is completely generic, you may register your own
2410 data types using your own custom renderers and editors. Just remember
2411 that the table must identify a cell as being of the given type for them
2412 to be used for this cell.
2415 Name of the new type. May be any string, but if the type name is
2416 the same as the name of an already registered type, including one
2417 of the standard ones (which are @c wxGRID_VALUE_STRING, @c
2418 wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
2419 and @c wxGRID_VALUE_CHOICE), then the new registration information
2420 replaces the previously used renderer and editor.
2422 The renderer to use for the cells of this type. Its ownership is
2423 taken by the grid, i.e. it will call DecRef() on this pointer when
2424 it doesn't need it any longer.
2426 The editor to use for the cells of this type. Its ownership is also
2429 void RegisterDataType(const wxString
& typeName

2434 Sets the value of the current grid cell to the current in-place edit
2437 This is called automatically when the grid cursor moves from the
2438 current cell to a new cell. It is also a good idea to call this
2439 function when closing a grid since any edits to the final cell location
2440 will not be saved otherwise.
2442 void SaveEditControlValue();
2445 Selects all cells in the grid.
2451 Selects a rectangular block of cells.
2453 If @a addToSelected is @false then any existing selection will be
2454 deselected; if @true the column will be added to the existing

2539 void SetCellTextColour(const wxColour
& val
, int row
, int col
);
2540 void SetCellTextColour(const wxColour
& colour
);
2545 Sets the string value for the cell at the specified location.
2547 For simple applications where a grid object automatically uses a
2548 default grid table of string values you use this function together with
2549 GetCellValue() to access cell values. For more complex applications
2550 where you have derived your own grid table class that contains various
2551 data types (e.g. numeric, boolean or user-defined custom types) then
2552 you only use this function for those cells that contain string values.
2553 The last form is for backward compatibility only.

2556 "wxGrid overview" for more information.

2574 @see SetColFormatCustom()
2576 void SetColFormatBool(int col

2579 Sets the specified column to display data in a custom format.
2581 This method provides an alternative to defining a custom grid table
2582 which would return @a typeName from its GetTypeName() method for the
2583 cells in this column: while it doesn't really change the type of the
2584 cells in this column, it does associate the renderer and editor used
2585 for the cells of the specified type with them.
2587 See the @ref overview_gridoverview "wxGrid overview" for more
2588 information on working with custom data types.
2590 void SetColFormatCustom(int col

2603 @see SetColFormatCustom()
2605 void SetColFormatNumber(int col

2608 Sets the horizontal and vertical alignment of column label text.
2610 Horizontal alignment should be one of @c wxALIGN_LEFT, @c
2611 wxALIGN_CENTRE or @c wxALIGN_RIGHT.
2612 Vertical alignment should be one of @c wxALIGN_TOP, @c wxALIGN_CENTRE
2613 or @c wxALIGN_BOTTOM.
2615 void SetColLabelAlignment(int horiz
, int vert
);
2618 Sets the height of the column labels.
2620 If @a height equals to @c wxGRID_AUTOSIZE then height is calculated
2621 automatically so that no label is truncated. Note that this could be
2622 slow for a large table.
2624 void SetColLabelSize(int height
);
2627 Set the value for the given column label.
2629 If you are using a custom grid table you must override
2630 wxGridTableBase::SetColLabelValue for this to have any effect.
2632 void SetColLabelValue(int col
, const wxString
& value
);
2635 Sets the minimal width to which the user can resize columns.
2637 @see GetColMinimalAcceptableWidth()
2639 void SetColMinimalAcceptableWidth(int width
);
2642 Sets the minimal width for the specified column.
2644 It is usually best to call this method during grid creation as calling
2645 it later will not resize the column to the given minimal width even if
2646 it is currently narrower than it.
2648 @a width must be greater than the minimal acceptable column width as
2649 returned by GetColMinimalAcceptableWidth().
2651 void SetColMinimalWidth(int col
, int width
);
2654 Sets the position of the specified column.
2656 void SetColPos(int colID

2662 ForceRefresh() to make the changes take effect immediately.
2667 The new column width in pixels or a negative value to fit the
2668 column width to its label width.
2670 void SetColSize(int col
, int width

2673 Sets the default horizontal and vertical alignment for grid cell text.
2675 Horizontal alignment should be one of @c wxALIGN_LEFT, @c
2676 wxALIGN_CENTRE or @c wxALIGN_RIGHT.
2677 Vertical alignment should be one of @c wxALIGN_TOP, @c wxALIGN_CENTRE
2678 or @c wxALIGN_BOTTOM.
2680 void SetDefaultCellAlignment(int horiz
, int vert
);
2683 Sets the default background colour for grid cells.
2685 void SetDefaultCellBackgroundColour(const wxColour

2698 Sets the default width for columns in the grid.
2700 This will only affect columns subsequently added to the grid unless
2701 @a resizeExistingCols is @true.

2729 Sets the default height for rows in the grid.
2731 This will only affect rows subsequently added to the grid unless
2732 @a resizeExistingRows is @true.
2734 If @a height is less than GetRowMinimalAcceptableHeight(), then the
2735 minimal acceptable heihgt is used instead of it.
2737 void SetDefaultRowSize(int height
, bool resizeExistingRows

2741 Set the grid cursor to the specified cell.
2743 The grid cursor indicates the current cell and can be moved by the user
2744 using the arrow keys or the mouse.
2746 Calling this function generates a wxEVT_GRID_SELECT_CELL event and if
2747 the event handler vetoes this event, the cursor is not moved.
2749 This function doesn't make the target call visible, use GoToCell() to

2888 Passes a pointer to a custom grid table to be used by the grid.
2890 This should be called after the grid constructor and before using the
2891 grid object. If @a takeOwnership is set to @true then the table will be
2892 deleted by the wxGrid destructor.
2894 Use this function instead of CreateGrid() when your application

2904 wxRenderer::DrawHeaderButton internally.
2906 There is no equivalent method for drawing row columns as there is not
2907 native look for that. This option is useful when using wxGrid for
2908 displaying tables and not as a spread-sheet.
2910 void SetUseNativeColLabels(bool native
= true);
2913 Displays the in-place cell edit control for the current cell.
2915 void ShowCellEditControl();
2918 Returns the column at the given pixel position.
2921 The x position to evaluate.
2923 If @true, rather than returning wxNOT_FOUND, it returns either the
2924 first or last column depending on whether x is too far to the left
2925 or right respectively.
2927 The column index or wxNOT_FOUND.
2929 int XToCol(int x
, bool clipToMinMax
= false) const;
2932 Returns the column whose right hand edge is close to the given logical
2935 If no column edge is near to this position @c wxNOT_FOUND is returned.
2937 int XToEdgeOfCol(int x
) const;
2941 Translates logical pixel coordinates to the grid cell coordinates.
2943 Notice that this function expects logical coordinates on input so if
2944 you use this function in a mouse event handler you need to translate
2945 the mouse position, which is expressed in device coordinates, to
2948 @see XToCol(), YToRow()
2951 // XYToCell(int, int, wxGridCellCoords&) overload is intentionally
2952 // undocumented, using it is ugly and non-const reference parameters are
2953 // not used in wxWidgets API
2955 wxGridCellCoords
XYToCell(int x
, int y
) const;
2956 wxGridCellCoords
XYToCell(const wxPoint
& pos
) const;
2961 Returns the row whose bottom edge is close to the given logical y
2964 If no row edge is near to this position @c wxNOT_FOUND is returned.
2966 int YToEdgeOfRow(int y
) const;
2969 Returns the grid row that corresponds to the logical y coordinate.
2971 Returns @c wxNOT_FOUND if there is no row at the y position.
2973 int YToRow(int y
) const;
2979 @class wxGridCellBoolEditor
2981 The editor for boolean data.
2986 @see wxGridCellEditor, wxGridCellFloatEditor, wxGridCellNumberEditor,
2987 wxGridCellTextEditor, wxGridCellChoiceEditor
2989 class wxGridCellBoolEditor
: public wxGridCellEditor
2993 Default constructor.
2995 wxGridCellBoolEditor();
2998 Returns @true if the given @a value is equal to the string representation of
2999 the truth value we currently use (see
3000 wxGridCellBoolEditor::UseStringValues).
3002 static bool IsTrueValue(const wxString
& value
);
3005 , wxString&@e valueFalse = _T(""))
3006 This method allows to customize the values returned by GetValue() method for
3007 the cell using this editor. By default, the default values of the arguments are
3008 used, i.e. @c "1" is returned if the cell is checked and an empty string
3009 otherwise, using this method allows to change this.
3011 static void UseStringValues() const;
3017 @class wxGridUpdateLocker
3019 This small class can be used to prevent wxGrid from redrawing
3020 during its lifetime by calling wxGrid::BeginBatch
3021 in its constructor and wxGrid::EndBatch in its
3022 destructor. It is typically used in a function performing several operations
3023 with a grid which would otherwise result in flicker. For example:
3028 m_grid = new wxGrid(this, ...);
3030 wxGridUpdateLocker noUpdates(m_grid);
3031 m_grid-AppendColumn();
3032 ... many other operations with m_grid...
3035 // destructor called, grid refreshed
3039 Using this class is easier and safer than calling
3040 wxGrid::BeginBatch and wxGrid::EndBatch
3041 because you don't risk not to call the latter (due to an exception for example).
3046 class wxGridUpdateLocker
3050 Creates an object preventing the updates of the specified @e grid. The
3051 parameter could be @NULL in which case nothing is done. If @a grid is
3052 non-@NULL then the grid must exist for longer than wxGridUpdateLocker object
3054 The default constructor could be followed by a call to
3058 wxGridUpdateLocker(wxGrid
* grid
= NULL
);
3061 Destructor reenables updates for the grid this object is associated with.
3063 ~wxGridUpdateLocker();
3066 This method can be called if the object had been constructed using the default
3067 constructor. It must not be called more than once.
3069 void Create(wxGrid
* grid
);
