14 cell or to wxGrid::SetDefaultRenderer() to change the view of all cells.

16 derived classes or derive your own class from it.

1064 Class providing attributes to be used for the grid cells.
1065
1066 This class both defines an interface which grid cell attributes providers
1067 should implement -- and which can be implemented differently in derived
1068 classes -- and a default implementation of this interface which is often
1069 good enough to be used without modification, especially with not very large
1070 grids for which the efficiency of attributes storage hardly matters (see
1071 the discussion below).
1072
1073 An object of this class can be associated with a wxGrid using
1074 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1075 intend to use the default provider as it is used by wxGridTableBase by
1076 default anyhow.
1077
1078 Notice that while attributes provided by this class can be set for
1079 individual cells using SetAttr() or the entire rows or columns using
1080 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1081 function.
1082
1083
1084 The default implementation of this class stores the attributes passed to
1085 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1086 derived class may use its knowledge about how the attributes are used in
1087 your program to implement it much more efficiently: for example, using a
1088 special background colour for all even-numbered rows can be implemented by
1089 simply returning the same attribute from GetAttr() if the row number is
1090 even instead of having to store N/2 row attributes where N is the total
1091 number of rows in the grid.

1675
1676 wxGrid and its related classes are used for displaying and editing tabular
1677 data. They provide a rich set of features for display, editing, and
1678 interacting with a variety of data sources. For simple applications, and to
1679 help you get started, wxGrid is the only class you need to refer to
1680 directly. It will set up default instances of the other classes and manage
1681 them for you. For more complex applications you can derive your own classes
1682 for custom grid views, grid data tables, cell editors and renderers. The
1683 @ref overview_grid has examples of simple and more complex applications,
1684 explains the relationship between the various grid classes and has a
1685 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1686
1687 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1688 class. One or more wxGrid classes may act as a view for one table class.
1689 The default table class is called wxGridStringTable and holds an array of
1690 strings. An instance of such a class is created by CreateGrid().
1691
1692 wxGridCellRenderer is the abstract base class for rendering contents in a
1693 cell. The following renderers are predefined:
1694
1695 - wxGridCellBoolRenderer
1696 - wxGridCellFloatRenderer
1697 - wxGridCellNumberRenderer
1698 - wxGridCellStringRenderer
1699
1700 The look of a cell can be further defined using wxGridCellAttr. An object
1701 of this type may be returned by wxGridTableBase::GetAttr().
1702
1703 wxGridCellEditor is the abstract base class for editing the value of a
1704 cell. The following editors are predefined:
1705
1706 - wxGridCellBoolEditor
1707 - wxGridCellChoiceEditor
1708 - wxGridCellFloatEditor
1709 - wxGridCellNumberEditor
1710 - wxGridCellTextEditor
1711

2084 code itself. This has the advantage of making the grid look and feel
2085 perfectly the same as native applications (using SetUseNativeColLabels()
2086 the grid can be made to look more natively but it still doesn't feel
2087 natively, notably the column resizing and dragging still works slightly
2088 differently as it is implemented in wxWidgets itself) but results in
2089 different behaviour for column and row headers, for which there is no
2090 equivalent function, and, most importantly, is unsuitable for grids
2091 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2092 mode. Because of this, by default the grid does not use the native
2093 header control but you should call this function to enable it if you
2094 are using the grid to display tabular data and don't have thousands of
2095 columns in it.
2096
2097 Another difference between the default behaviour and the native header
2098 behaviour is that the latter provides the user with a context menu
2099 (which appears on right clicking the header) allowing to rearrange the
2100 grid columns if CanDragColMove() returns @true. If you want to prevent
2101 this from happening for some reason, you need to define a handler for
2102 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2103 particular doesn't skip the event) as this will prevent the default
2104 right click handling from working.
2105
2106 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2107 generated for the column labels if the native columns header is used

4145 performing several operations with a grid which would otherwise result in

4147
4148 @code
4149 void MyFrame::Foo()

4209 CMD takes the id as first argument and the event handler as the second one
4210 and so can be used with multiple grids as well. Otherwise there are no

4218 can be vetoed if the change is not allowed.

4222 available from GetString() event object method. Notice that vetoing
4223 this event still works for backwards compatibility reasons but any new
4224 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4225 Processes a @c wxEVT_GRID_CELL_CHANGED event type.

4246 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4247 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4248 The user double-clicked a label with the left mouse button. Processes a
4249 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4250 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4251 The user clicked a label with the right mouse button. Processes a
4252 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4253 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}

4256 @event{EVT_GRID_SELECT_CELL(func)}
4257 The given cell was made current, either by user or by the program via a
4258 call to SetGridCursor() or GoToCell(). Processes a
4259 @c wxEVT_GRID_SELECT_CELL event type.
4260 @event{EVT_GRID_COL_MOVE(func)}
4261 The user tries to change the order of the columns in the grid by
4262 dragging the column specified by GetCol(). This event can be vetoed to
4263 either prevent the user from reordering the column change completely
4264 (but notice that if you don't want to allow it at all, you simply
4265 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4266 but handled in some way in the handler, e.g. by really moving the
4267 column to the new position at the associated table level, or allowed to
4268 proceed in which case wxGrid::SetColPos() is used to reorder the
4269 columns display order without affecting the use of the column indices
4270 otherwise.
4271 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4272 @event{EVT_GRID_COL_SORT(func)}
4273 This event is generated when a column is clicked by the user and its
4274 name is explained by the fact that the custom reaction to a click on a
4275 column is to sort the grid contents by this column. However the grid
4276 itself has no special support for sorting and it's up to the handler of
4277 this event to update the associated table. But if the event is handled
4278 (and not vetoed) the grid supposes that the table was indeed resorted
4279 and updates the column to indicate the new sort order and refreshes
4280 itself.
4281 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
