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

257 If the editor is enabled by pressing keys on the grid, this will be
258 called to let the editor do something about that first key if desired.

297 This method allows you to customize the values returned by GetValue()
298 for the cell using this editor. By default, the default values of the
299 arguments are used, i.e. @c "1" is returned if the cell is checked and

600 @class wxGridTableBase
602 The almost abstract base class for grid tables.
604 A grid table is responsible for storing the grid data and, indirectly, grid
605 cell attributes. The data can be stored in the way most convenient for the
606 application but has to be provided in string form to wxGrid. It is also
607 possible to provide cells values in other formats if appropriate, e.g. as
610 This base class is not quite abstract as it implements a trivial strategy
611 for storing the attributes by forwarding it to wxGridCellAttrProvider and
612 also provides stubs for some other functions. However it does have a number
613 of pure virtual methods which must be implemented in the derived classes.
615 @see wxGridStringTable
620 class wxGridTableBase
: public wxObject
629 Destructor frees the attribute provider if it was created.
631 virtual ~wxGridTableBase();
634 Must be overridden to return the number of rows in the table.
636 For backwards compatibility reasons, this method is not const.
637 Use GetRowsCount() instead of it in const methods of derived table
640 virtual int GetNumberRows() = 0;
643 Must be overridden to return the number of columns in the table.
645 For backwards compatibility reasons, this method is not const.
646 Use GetColsCount() instead of it in const methods of derived table
649 virtual int GetNumberCols() = 0;
652 Return the number of rows in the table.
654 This method is not virtual and is only provided as a convenience for
655 the derived classes which can't call GetNumberRows() without a
656 @c const_cast from their const methods.
658 int GetRowsCount() const;
661 Return the number of columns in the table.
663 This method is not virtual and is only provided as a convenience for
664 the derived classes which can't call GetNumberCols() without a
665 @c const_cast from their const methods.
667 int GetColsCount() const;
671 @name Table Cell Accessors
676 May be overridden to implement testing for empty cells.
678 This method is used by the grid to test if the given cell is not used
679 and so whether a neighbouring cell may overflow into it. By default it
680 only returns true if the value of the given cell, as returned by
681 GetValue(), is empty.
683 virtual bool IsEmptyCell(int row
, int col
);
686 Same as IsEmptyCell() but taking wxGridCellCoords.
688 Notice that this method is not virtual, only IsEmptyCell() should be
691 bool IsEmpty(const wxGridCellCoords
& coords
);
694 Must be overridden to implement accessing the table values as text.
696 virtual wxString
GetValue(int row
, int col
) = 0;
699 Must be overridden to implement setting the table values as text.
701 virtual void SetValue(int row
, int col
, const wxString
& value
) = 0;
704 Returns the type of the value in the given cell.
706 By default all cells are strings and this method returns
707 @c wxGRID_VALUE_STRING.
709 virtual wxString
GetTypeName(int row
, int col
);
712 Returns true if the value of the given cell can be accessed as if it
713 were of the specified type.
715 By default the cells can only be accessed as strings. Note that a cell
716 could be accessible in different ways, e.g. a numeric cell may return
717 @true for @c wxGRID_VALUE_NUMBER but also for @c wxGRID_VALUE_STRING
718 indicating that the value can be coerced to a string form.
720 virtual bool CanGetValueAs(int row
, int col
, const wxString
& typeName
);
723 Returns true if the value of the given cell can be set as if it were of
728 virtual bool CanSetValueAs(int row
, int col
, const wxString
& typeName
);
731 Returns the value of the given cell as a long.
733 This should only be called if CanGetValueAs() returns @true when called
734 with @c wxGRID_VALUE_NUMBER argument. Default implementation always
737 virtual long GetValueAsLong(int row
, int col
);
740 Returns the value of the given cell as a double.
742 This should only be called if CanGetValueAs() returns @true when called
743 with @c wxGRID_VALUE_FLOAT argument. Default implementation always
746 virtual double GetValueAsDouble(int row
, int col
);
749 Returns the value of the given cell as a boolean.
751 This should only be called if CanGetValueAs() returns @true when called
752 with @c wxGRID_VALUE_BOOL argument. Default implementation always
755 virtual bool GetValueAsBool(int row
, int col
);
758 Returns the value of the given cell as a user-defined type.
760 This should only be called if CanGetValueAs() returns @true when called
761 with @a typeName. Default implementation always return @NULL.
763 virtual void *GetValueAsCustom(int row
, int col
, const wxString
& typeName
);
766 Sets the value of the given cell as a long.
768 This should only be called if CanSetValueAs() returns @true when called
769 with @c wxGRID_VALUE_NUMBER argument. Default implementation doesn't do
772 virtual void SetValueAsLong(int row
, int col
, long value
);
775 Sets the value of the given cell as a double.
777 This should only be called if CanSetValueAs() returns @true when called
778 with @c wxGRID_VALUE_FLOAT argument. Default implementation doesn't do
781 virtual void SetValueAsDouble(int row
, int col
, double value
);
784 Sets the value of the given cell as a boolean.
786 This should only be called if CanSetValueAs() returns @true when called
787 with @c wxGRID_VALUE_BOOL argument. Default implementation doesn't do
790 virtual void SetValueAsBool( int row
, int col
, bool value
);
793 Sets the value of the given cell as a user-defined type.
795 This should only be called if CanSetValueAs() returns @true when called
796 with @a typeName. Default implementation doesn't do anything.
798 virtual void SetValueAsCustom(int row
, int col
, const wxString
& typeName
,
805 Called by the grid when the table is associated with it.
807 The default implementation stores the pointer and returns it from its
808 GetView() and so only makes sense if the table cannot be associated
809 with more than one grid at a time.
811 virtual void SetView(wxGrid
*grid
);
814 Returns the last grid passed to SetView().
816 virtual wxGrid
*GetView() const;
820 @name Table Structure Modifiers
822 Notice that none of these functions are pure virtual as they don't have
823 to be implemented if the table structure is never modified after
824 creation, i.e. neither rows nor columns are never added or deleted but
825 that you do need to implement them if they are called, i.e. if your
826 code either calls them directly or uses the matching wxGrid methods, as
827 by default they simply do nothing which is definitely inappropriate.
832 Clear the table contents.
834 This method is used by wxGrid::ClearGrid().
836 virtual void Clear();
839 Insert additional rows into the table.
842 The position of the first new row.
844 The number of rows to insert.
846 virtual bool InsertRows(size_t pos
= 0, size_t numRows
= 1);
849 Append additional rows at the end of the table.
851 This method is provided in addition to InsertRows() as some data models
852 may only support appending rows to them but not inserting them at
853 arbitrary locations. In such case you may implement this method only
854 and leave InsertRows() unimplemented.
857 The number of rows to add.
859 virtual bool AppendRows(size_t numRows
= 1);
862 Delete rows from the table.
865 The first row to delete.
867 The number of rows to delete.
869 virtual bool DeleteRows(size_t pos
= 0, size_t numRows
= 1);
872 Exactly the same as InsertRows() but for columns.
874 virtual bool InsertCols(size_t pos
= 0, size_t numCols
= 1);
877 Exactly the same as AppendRows() but for columns.
879 virtual bool AppendCols(size_t numCols
= 1);
882 Exactly the same as DeleteRows() but for columns.
884 virtual bool DeleteCols(size_t pos
= 0, size_t numCols
= 1);
889 @name Table Row and Column Labels
891 By default the numbers are used for labeling rows and Latin letters for
892 labeling columns. If the table has more than 26 columns, the pairs of
893 letters are used starting from the 27-th one and so on, i.e. the
894 sequence of labels is A, B, ..., Z, AA, AB, ..., AZ, BA, ..., ..., ZZ,
900 Return the label of the specified row.
902 virtual wxString
GetRowLabelValue(int row
);
905 Return the label of the specified column.
907 virtual wxString
GetColLabelValue(int col
);
910 Set the given label for the specified row.
912 The default version does nothing, i.e. the label is not stored. You
913 must override this method in your derived class if you wish
914 wxGrid::SetRowLabelValue() to work.
916 virtual void SetRowLabelValue(int row
, const wxString
& label
);
919 Exactly the same as SetRowLabelValue() but for columns.
921 virtual void SetColLabelValue(int col
, const wxString
& label
);
927 @name Attributes Management
929 By default the attributes management is delegated to
930 wxGridCellAttrProvider class. You may override the methods in this
931 section to handle the attributes directly if, for example, they can be
932 computed from the cell values.
937 Associate this attributes provider with the table.
939 The table takes ownership of @a attrProvider pointer and will delete it
940 when it doesn't need it any more. The pointer can be @NULL, however
941 this won't disable attributes management in the table but will just
942 result in a default attributes being recreated the next time any of the
943 other functions in this section is called. To completely disable the
944 attributes support, should this be needed, you need to override
945 CanHaveAttributes() to return @false.
947 void SetAttrProvider(wxGridCellAttrProvider
*attrProvider
);
950 Returns the attribute provider currently being used.
952 This function may return @NULL if the attribute provider hasn't been
953 neither associated with this table by SetAttrProvider() nor created on
954 demand by any other methods.
956 wxGridCellAttrProvider
*GetAttrProvider() const;
959 Return the attribute for the given cell.
961 By default this function is simply forwarded to
962 wxGridCellAttrProvider::GetAttr() but it may be overridden to handle
963 attributes directly in the table.
965 virtual wxGridCellAttr
*GetAttr(int row
, int col
,
966 wxGridCellAttr
::wxAttrKind kind
);
969 Set attribute of the specified cell.
971 By default this function is simply forwarded to
972 wxGridCellAttrProvider::SetAttr().
974 The table takes ownership of @a attr, i.e. will call DecRef() on it.
976 virtual void SetAttr(wxGridCellAttr
* attr
, int row
, int col
);
979 Set attribute of the specified row.
981 By default this function is simply forwarded to
982 wxGridCellAttrProvider::SetRowAttr().
984 The table takes ownership of @a attr, i.e. will call DecRef() on it.
986 virtual void SetRowAttr(wxGridCellAttr
*attr
, int row
);
989 Set attribute of the specified column.
991 By default this function is simply forwarded to
992 wxGridCellAttrProvider::SetColAttr().
994 The table takes ownership of @a attr, i.e. will call DecRef() on it.
996 virtual void SetColAttr(wxGridCellAttr
*attr
, int col
);
1001 Returns true if this table supports attributes or false otherwise.
1003 By default, the table automatically creates a wxGridCellAttrProvider
1004 when this function is called if it had no attribute provider before and
1007 virtual bool CanHaveAttributes();
1015 wxGrid and its related classes are used for displaying and editing tabular
1016 data. They provide a rich set of features for display, editing, and
1017 interacting with a variety of data sources. For simple applications, and to
1018 help you get started, wxGrid is the only class you need to refer to
1019 directly. It will set up default instances of the other classes and manage
1020 them for you. For more complex applications you can derive your own classes
1021 for custom grid views, grid data tables, cell editors and renderers. The
1022 @ref overview_grid has examples of simple and more complex applications,
1023 explains the relationship between the various grid classes and has a
1024 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1026 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1027 class. One or more wxGrid classes may act as a view for one table class.
1028 The default table class is called wxGridStringTable and holds an array of
1029 strings. An instance of such a class is created by CreateGrid().
1031 wxGridCellRenderer is the abstract base class for rendereing contents in a
1032 cell. The following renderers are predefined:
1034 - wxGridCellBoolRenderer
1035 - wxGridCellFloatRenderer
1036 - wxGridCellNumberRenderer
1037 - wxGridCellStringRenderer

1040 of this type may be returned by wxGridTableBase::GetAttr().
1042 wxGridCellEditor is the abstract base class for editing the value of a
1043 cell. The following editors are predefined:

1138 Creates a grid with the specified initial number of rows and columns.
1140 Call this directly after the grid constructor. When you use this
1141 function wxGrid will create and manage a simple table of string values
1142 for you. All of the grid data will be stored in memory.
1144 For applications with more complex data types or relationships, or for
1145 dealing with very large datasets, you should derive your own grid table
1146 class and pass a table object to the grid with SetTable().
1148 bool CreateGrid(int numRows
, int numCols
,
1149 wxGridSelectionModes selmode

1152 Passes a pointer to a custom grid table to be used by the grid.
1154 This should be called after the grid constructor and before using the
1155 grid object. If @a takeOwnership is set to @true then the table will be
1156 deleted by the wxGrid destructor.
1158 Use this function instead of CreateGrid() when your application
1159 involves complex or non-string data or data sets that are too large to
1160 fit wholly in memory.

1242 @name Label Values and Formatting
1247 Sets the arguments to the current column label alignment values.
1249 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1250 or @c wxALIGN_RIGHT.

1276 wxColour
GetLabelBackgroundColour() const;
1279 Returns the font used for row and column labels.
1281 wxFont
GetLabelFont() const;
1284 Returns the colour used for row and column label text.
1286 wxColour
GetLabelTextColour() const;
1289 Returns the alignment used for row labels.
1291 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1292 or @c wxALIGN_RIGHT.
1294 Vertical alignment will be one of @c wxALIGN_TOP, @c wxALIGN_CENTRE or
1297 void GetRowLabelAlignment(int* horiz
, int* vert
) const;
1300 Returns the specified row label.
1302 The default grid table class provides numeric row labels. If you are
1303 using a custom grid table you can override
1304 wxGridTableBase::GetRowLabelValue() to provide your own labels.
1306 wxString

1309 Hides the column labels by calling SetColLabelSize() with a size of 0.
1310 Show labels again by calling that method with a width greater than 0.

1315 Hides the row labels by calling SetRowLabelSize() with a size of 0.
1317 The labels can be shown again by calling SetRowLabelSize() with a width
1320 void HideRowLabels();
1323 Sets the horizontal and vertical alignment of column label text.
1325 Horizontal alignment should be one of @c wxALIGN_LEFT,
1326 @c wxALIGN_CENTRE or @c wxALIGN_RIGHT. Vertical alignment should be one
1327 of @c wxALIGN_TOP, @c wxALIGN_CENTRE or @c wxALIGN_BOTTOM.
1329 void SetColLabelAlignment(int horiz
, int vert
);
1332 Sets the orientation of the column labels (either @c wxHORIZONTAL or
1335 void SetColLabelTextOrientation(int textOrientation
);
1338 Set the value for the given column label.
1340 If you are using a custom grid table you must override
1341 wxGridTableBase::SetColLabelValue() for this to have any effect.

1365 of @c wxALIGN_TOP, @c wxALIGN_CENTRE or @c wxALIGN_BOTTOM.
1367 void SetRowLabelAlignment(int horiz
, int vert
);
1370 Sets the value for the given row label.
1372 If you are using a derived grid table you must override
1373 wxGridTableBase::SetRowLabelValue() for this to have any effect.
1375 void SetRowLabelValue(int row
, const wxString
& value
);
1378 Call this in order to make the column labels use a native look by using
1379 wxRenderer::DrawHeaderButton() internally.
1381 There is no equivalent method for drawing row columns as there is not
1382 native look for that. This option is useful when using wxGrid for
1383 displaying tables and not as a spread-sheet.
1385 @see UseNativeHeader()
1387 void SetUseNativeColLabels(bool native
= true);
1390 Enable the use of native header window for column labels.
1392 If this function is called with @true argument, a wxHeaderCtrl is used
1393 instead to display the column labels instead of drawing them in wxGrid
1394 code itself. This has the advantage of making the grid look and feel
1395 perfectly the same as native applications (using SetUseNativeColLabels()
1396 the grid can be made to look more natively but it still doesn't feel
1397 natively, notably the column resizing and dragging still works slightly
1398 differently as it is implemented in wxWidgets itself) but results in
1399 different behaviour for column and row headers, for which there is no
1400 equivalent function, and, most importantly, is unsuitable for grids
1401 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
1402 mode. Because of this, by default the grid does not use the native
1403 header control but you should call this function to enable it if you
1404 are using the grid to display tabular data and don't have thousands of
1407 Also note that currently @c wxEVT_GRID_LABEL_LEFT_DCLICK and @c
1408 wxEVT_GRID_LABEL_RIGHT_DCLICK events are not generated for the column
1409 labels if the native columns header is used (but this limitation could
1410 possibly be lifted in the future).

= true);
1418 @name Cell Formatting
1420 Note that wxGridCellAttr can be used alternatively to most of these
1421 methods. See the "Attributes Management" of wxGridTableBase.
1426 Sets the arguments to the horizontal and vertical text alignment values
1427 for the grid cell at the specified location.
1429 Horizontal alignment will be one of @c wxALIGN_LEFT, @c wxALIGN_CENTRE
1430 or @c wxALIGN_RIGHT.

1554 @name Cell Values, Editors, and Renderers
1556 Note that wxGridCellAttr can be used alternatively to most of these
1557 methods. See the "Attributes Management" of wxGridTableBase.
1562 Returns @true if the in-place edit control for the current grid cell
1563 can be used and @false otherwise.
1565 This function always returns @false for the read-only cells.
1567 bool CanEnableCellControl() const;
1570 Disables in-place editing of grid cells.
1572 Equivalent to calling EnableCellEditControl(@false).
1574 void DisableCellEditControl();
1577 Enables or disables in-place editing of grid cell data.
1579 The grid will issue either a @c wxEVT_GRID_EDITOR_SHOWN or
1580 @c wxEVT_GRID_EDITOR_HIDDEN event.
1582 void EnableCellEditControl(bool enable
= true);
1585 Makes the grid globally editable or read-only.
1587 If the edit argument is @false this function sets the whole grid as
1588 read-only. If the argument is @true the grid is set to the default
1589 state where cells may be editable. In the default state you can set
1590 single grid cells and whole rows and columns to be editable or
1591 read-only via wxGridCellAttr::SetReadOnly(). For single cells you
1592 can also use the shortcut function SetReadOnly().

1624 default grid table of string values you use this function together with
1625 SetCellValue() to access cell values. For more complex applications
1626 where you have derived your own grid table class that contains various
1627 data types (e.g. numeric, boolean or user-defined custom types) then

1760 Register a new data type.
1762 The data types allow to naturally associate specific renderers and
1763 editors to the cells containing values of the given type. For example,
1764 the grid automatically registers a data type with the name
1765 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
1766 wxGridCellTextEditor as its renderer and editor respectively -- this is
1767 the data type used by all the cells of the default wxGridStringTable,
1768 so this renderer and editor are used by default for all grid cells.
1770 However if a custom table returns @c wxGRID_VALUE_BOOL from its
1771 wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
1772 wxGridCellBoolEditor are used for it because the grid also registers a
1773 boolean data type with this name.
1775 And as this mechanism is completely generic, you may register your own
1776 data types using your own custom renderers and editors. Just remember
1777 that the table must identify a cell as being of the given type for them
1778 to be used for this cell.
1781 Name of the new type. May be any string, but if the type name is
1782 the same as the name of an already registered type, including one
1783 of the standard ones (which are @c wxGRID_VALUE_STRING, @c
1784 wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
1785 and @c wxGRID_VALUE_CHOICE), then the new registration information
1786 replaces the previously used renderer and editor.
1788 The renderer to use for the cells of this type. Its ownership is
1789 taken by the grid, i.e. it will call DecRef() on this pointer when
1790 it doesn't need it any longer.
1792 The editor to use for the cells of this type. Its ownership is also

1800 Sets the value of the current grid cell to the current in-place edit
1803 This is called automatically when the grid cursor moves from the
1804 current cell to a new cell. It is also a good idea to call this
1805 function when closing a grid since any edits to the final cell location
1806 will not be saved otherwise.
1808 void SaveEditControlValue();
1811 Sets the editor for the grid cell at the specified location.
1813 The grid will take ownership of the pointer.

2851 Increments the grid's batch count.
2853 When the count is greater than zero repainting of the grid is
2854 suppressed. Each call to BeginBatch must be matched by a later call to
2855 EndBatch(). Code that does a lot of grid modification can be enclosed
2856 between BeginBatch() and EndBatch() calls to avoid screen flicker. The
2857 final EndBatch() call will cause the grid to be repainted.
2859 Notice that you should use wxGridUpdateLocker which ensures that there
2860 is always a matching EndBatch() call for this BeginBatch() if possible
2861 instead of calling this method directly.
2866 Clears all data in the underlying grid table and repaints the grid.

2950 Returns the number of times that BeginBatch() has been called without
2951 (yet) matching calls to EndBatch(). While the grid's batch count is
2952 greater than zero the display will not be updated.
2954 int GetBatchCount();

2973 If the cell already has an attribute, it is returned. Otherwise a new
2974 attribute is created, associated with the cell and returned. In any
2975 case the caller must call DecRef() on the returned pointer.

2989 Inserts one or more new columns into a grid with the first new column
2990 at the specified position.
2992 Notice that inserting the columns in the grid requires grid table
2993 cooperation: when this method is called, grid object begins by
2994 requesting the underlying grid table to insert new columns. If this is
2995 successful the table notifies the grid and the grid updates the
2996 display. For a default grid (one where you have called CreateGrid())
2997 this process is automatic. If you are using a custom grid table
2998 (specified with SetTable()) then you must override

3101 @name Sorting support.
3103 wxGrid doesn't provide any support for sorting the data but it does
3104 generate events allowing the user code to sort it and supports
3105 displaying the sort indicator in the column used for sorting.
3107 To use wxGrid sorting support you need to handle wxEVT_GRID_COL_SORT
3108 event (and not veto it) and resort the data displayed in the grid. The
3109 grid will automatically update the sorting indicator on the column
3112 You can also call the functions in this section directly to update the
3113 sorting indicator. Once again, they don't do anything with the grid
3114 data, it remains your responsibility to actually sort it appropriately.
3119 Return the column in which the sorting indicator is currently
3122 Returns @c wxNOT_FOUND if sorting indicator is not currently displayed
3125 @see SetSortingColumn()
3127 int GetSortingColumn() const;
3130 Return @true if this column is currently used for sorting.
3132 @see GetSortingColumn()
3134 bool IsSortingBy(int col
) const;
3137 Return @true if the current sorting order is ascending or @false if it
3140 It only makes sense to call this function if GetSortingColumn() returns
3141 a valid column index and not @c wxNOT_FOUND.
3143 @see SetSortingColumn()
3145 bool IsSortOrderAscending() const;
3148 Set the column to display the sorting indicator in and its direction.
3151 The column to display the sorting indicator in or @c wxNOT_FOUND to
3152 remove any currently displayed sorting indicator.
3154 If @true, display the ascending sort indicator, otherwise display
3155 the descending sort indicator.
3157 @see GetSortingColumn(), IsSortOrderAscending()
3159 void SetSortingColumn(int col
, bool ascending
= true);
3162 Remove any currently shown sorting indicator.
3164 This is equivalent to calling SetSortingColumn() with @c wxNOT_FOUND
3167 void UnsetSortingColumn();
3174 @class wxGridUpdateLocker
3176 This small class can be used to prevent wxGrid from redrawing during its
3177 lifetime by calling wxGrid::BeginBatch() in its constructor and
3178 wxGrid::EndBatch() in its destructor. It is typically used in a function
3179 performing several operations with a grid which would otherwise result in
3180 flicker. For example:
3185 m_grid = new wxGrid(this, ...);
3187 wxGridUpdateLocker noUpdates(m_grid);
3188 m_grid-AppendColumn();
3189 // ... many other operations with m_grid ...
3192 // destructor called, grid refreshed
3196 Using this class is easier and safer than calling wxGrid::BeginBatch() and
3197 wxGrid::EndBatch() because you don't risk missing the call the latter (due
3198 to an exception for example).
3203 class wxGridUpdateLocker
3207 Creates an object preventing the updates of the specified @a grid. The
3208 parameter could be @NULL in which case nothing is done. If @a grid is
3209 non-@NULL then the grid must exist for longer than this
3210 wxGridUpdateLocker object itself.
3212 The default constructor could be followed by a call to Create() to set
3213 the grid object later.
3215 wxGridUpdateLocker(wxGrid
* grid
= NULL
);
3218 Destructor reenables updates for the grid this object is associated
3221 ~wxGridUpdateLocker();
3224 This method can be called if the object had been constructed using the
3225 default constructor. It must not be called more than once.
3227 void Create(wxGrid
* grid
);
3235 This event class contains information about various grid events.
3237 Notice that all grid event table macros are available in two versions:
3238 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
3239 two is that the former doesn't allow to specify the grid window identifier
3240 and so takes a single parameter, the event handler, but is not suitable if
3241 there is more than one grid control in the window where the event table is
3242 used (as it would catch the events from all the grids). The version with @c
3243 CMD takes the id as first argument and the event handler as the second one
3244 and so can be used with multiple grids as well. Otherwise there are no
3245 difference between the two and only the versions without the id are
3246 documented below for brevity.
3248 @beginEventTable{wxGridEvent}
3249 @event{EVT_GRID_CELL_CHANGE(func)}
3250 The user changed the data in a cell. Processes a
3251 @c wxEVT_GRID_CELL_CHANGE event type.
3252 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
3253 The user clicked a cell with the left mouse button. Processes a
3254 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
3255 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}

3265 The editor for a cell was hidden. Processes a
3266 @c wxEVT_GRID_EDITOR_HIDDEN event type.
3267 @event{EVT_GRID_EDITOR_SHOWN(func)}
3268 The editor for a cell was shown. Processes a
3269 @c wxEVT_GRID_EDITOR_SHOWN event type.

3271 The user clicked a label with the left mouse button. Processes a
3272 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
3273 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
3274 The user double-clicked a label with the left mouse button. Processes a
3275 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
3276 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
3277 The user clicked a label with the right mouse button. Processes a
3278 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
3279 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
3280 The user double-clicked a label with the right mouse button. Processes
3281 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
3282 @event{EVT_GRID_SELECT_CELL(func)}
3283 The user moved to, and selected a cell. Processes a
3284 @c wxEVT_GRID_SELECT_CELL event type.
3285 @event{EVT_GRID_COL_MOVE(func)}
3286 The user tries to change the order of the columns in the grid by
3287 dragging the column specified by GetCol(). This event can be vetoed to
3288 either prevent the user from reordering the column change completely
3289 (but notice that if you don't want to allow it at all, you simply
3290 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
3291 but handled in some way in the handler, e.g. by really moving the
3292 column to the new position at the associated table level, or allowed to
3293 proceed in which case wxGrid::SetColPos() is used to reorder the
3294 columns display order without affecting the use of the column indices
3297 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
3298 @event{EVT_GRID_COL_SORT(func)}
3299 This event is generated when a column is clicked by the user and its
3300 name is explained by the fact that the custom reaction to a click on a
3301 column is to sort the grid contents by this column. However the grid
3302 itself has no special support for sorting and it's up to the handler of
3303 this event to update the associated table. But if the event is handled
3304 (and not vetoed) the grid supposes that the table was indeed resorted
3305 and updates the column to indicate the new sort order and refreshes
3308 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
