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.

1672
1673 wxGrid and its related classes are used for displaying and editing tabular
1674 data. They provide a rich set of features for display, editing, and
1675 interacting with a variety of data sources. For simple applications, and to
1676 help you get started, wxGrid is the only class you need to refer to
1677 directly. It will set up default instances of the other classes and manage
1678 them for you. For more complex applications you can derive your own classes
1679 for custom grid views, grid data tables, cell editors and renderers. The
1680 @ref overview_grid has examples of simple and more complex applications,
1681 explains the relationship between the various grid classes and has a
1682 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1683
1684 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1685 class. One or more wxGrid classes may act as a view for one table class.
1686 The default table class is called wxGridStringTable and holds an array of
1687 strings. An instance of such a class is created by CreateGrid().
1688
1689 wxGridCellRenderer is the abstract base class for rendering contents in a
1690 cell. The following renderers are predefined:
1691
1692 - wxGridCellBoolRenderer
1693 - wxGridCellFloatRenderer
1694 - wxGridCellNumberRenderer
1695 - wxGridCellStringRenderer
1696
1697 The look of a cell can be further defined using wxGridCellAttr. An object
1698 of this type may be returned by wxGridTableBase::GetAttr().
1699
1700 wxGridCellEditor is the abstract base class for editing the value of a
1701 cell. The following editors are predefined:
1702
1703 - wxGridCellBoolEditor
1704 - wxGridCellChoiceEditor
1705 - wxGridCellFloatEditor
1706 - wxGridCellNumberEditor
1707 - wxGridCellTextEditor
1708

2081 code itself. This has the advantage of making the grid look and feel
2082 perfectly the same as native applications (using SetUseNativeColLabels()
2083 the grid can be made to look more natively but it still doesn't feel
2084 natively, notably the column resizing and dragging still works slightly
2085 differently as it is implemented in wxWidgets itself) but results in
2086 different behaviour for column and row headers, for which there is no
2087 equivalent function, and, most importantly, is unsuitable for grids
2088 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2089 mode. Because of this, by default the grid does not use the native
2090 header control but you should call this function to enable it if you
2091 are using the grid to display tabular data and don't have thousands of
2092 columns in it.
2093
2094 Another difference between the default behaviour and the native header
2095 behaviour is that the latter provides the user with a context menu
2096 (which appears on right clicking the header) allowing to rearrange the
2097 grid columns if CanDragColMove() returns @true. If you want to prevent
2098 this from happening for some reason, you need to define a handler for
2099 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2100 particular doesn't skip the event) as this will prevent the default
2101 right click handling from working.
2102
2103 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not

4144
4145 @code
4146 void MyFrame::Foo()

4215 can be vetoed if the change is not allowed.

4219 available from GetString() event object method. Notice that vetoing
4220 this event still works for backwards compatibility reasons but any new
4221 code should only veto EVT_GRID_CELL_CHANGING event and not this one.

4253 @event{EVT_GRID_SELECT_CELL(func)}
4254 The given cell was made current, either by user or by the program via a
4255 call to SetGridCursor() or GoToCell(). Processes a
4256 @c wxEVT_GRID_SELECT_CELL event type.
4257 @event{EVT_GRID_COL_MOVE(func)}
4258 The user tries to change the order of the columns in the grid by
4259 dragging the column specified by GetCol(). This event can be vetoed to
4260 either prevent the user from reordering the column change completely
4261 (but notice that if you don't want to allow it at all, you simply
4262 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4263 but handled in some way in the handler, e.g. by really moving the
4264 column to the new position at the associated table level, or allowed to
4265 proceed in which case wxGrid::SetColPos() is used to reorder the
4266 columns display order without affecting the use of the column indices
4267 otherwise.
4268 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4269 @event{EVT_GRID_COL_SORT(func)}
4270 This event is generated when a column is clicked by the user and its
4271 name is explained by the fact that the custom reaction to a click on a
4272 column is to sort the grid contents by this column. However the grid
4273 itself has no special support for sorting and it's up to the handler of
4274 this event to update the associated table. But if the event is handled
4275 (and not vetoed) the grid supposes that the table was indeed resorted
4276 and updates the column to indicate the new sort order and refreshes
4277 itself.
4278 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
