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.

1008 Class providing attributes to be used for the grid cells.
1009
1010 This class both defines an interface which grid cell attributes providers
1011 should implement -- and which can be implemented differently in derived
1012 classes -- and a default implementation of this interface which is often
1013 good enough to be used without modification, especially with not very large
1014 grids for which the efficiency of attributes storage hardly matters (see
1015 the discussion below).
1016
1017 An object of this class can be associated with a wxGrid using
1018 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1019 intend to use the default provider as it is used by wxGridTableBase by
1020 default anyhow.
1021
1022 Notice that while attributes provided by this class can be set for
1023 individual cells using SetAttr() or the entire rows or columns using
1024 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1025 function.
1026
1027
1028 The default implementation of this class stores the attributes passed to
1029 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1030 derived class may use its knowledge about how the attributes are used in
1031 your program to implement it much more efficiently: for example, using a
1032 special background colour for all even-numbered rows can be implemented by
1033 simply returning the same attribute from GetAttr() if the row number is
1034 even instead of having to store N/2 row attributes where N is the total
1035 number of rows in the grid.

1616
1617 wxGrid and its related classes are used for displaying and editing tabular
1618 data. They provide a rich set of features for display, editing, and
1619 interacting with a variety of data sources. For simple applications, and to
1620 help you get started, wxGrid is the only class you need to refer to
1621 directly. It will set up default instances of the other classes and manage
1622 them for you. For more complex applications you can derive your own classes
1623 for custom grid views, grid data tables, cell editors and renderers. The
1624 @ref overview_grid has examples of simple and more complex applications,
1625 explains the relationship between the various grid classes and has a
1626 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1627
1628 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1629 class. One or more wxGrid classes may act as a view for one table class.
1630 The default table class is called wxGridStringTable and holds an array of
1631 strings. An instance of such a class is created by CreateGrid().
1632
1633 wxGridCellRenderer is the abstract base class for rendereing contents in a
1634 cell. The following renderers are predefined:
1635
1636 - wxGridCellBoolRenderer
1637 - wxGridCellFloatRenderer
1638 - wxGridCellNumberRenderer
1639 - wxGridCellStringRenderer
1640
1641 The look of a cell can be further defined using wxGridCellAttr. An object
1642 of this type may be returned by wxGridTableBase::GetAttr().
1643
1644 wxGridCellEditor is the abstract base class for editing the value of a
1645 cell. The following editors are predefined:
1646
1647 - wxGridCellBoolEditor
1648 - wxGridCellChoiceEditor
1649 - wxGridCellFloatEditor
1650 - wxGridCellNumberEditor
1651 - wxGridCellTextEditor
1652

2023 If this function is called with @true argument, a wxHeaderCtrl is used
2024 instead to display the column labels instead of drawing them in wxGrid
2025 code itself. This has the advantage of making the grid look and feel
2026 perfectly the same as native applications (using SetUseNativeColLabels()
2027 the grid can be made to look more natively but it still doesn't feel
2028 natively, notably the column resizing and dragging still works slightly
2029 differently as it is implemented in wxWidgets itself) but results in
2030 different behaviour for column and row headers, for which there is no
2031 equivalent function, and, most importantly, is unsuitable for grids
2032 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2033 mode. Because of this, by default the grid does not use the native
2034 header control but you should call this function to enable it if you
2035 are using the grid to display tabular data and don't have thousands of
2036 columns in it.
2037
2038 Another difference between the default behaviour and the native header
2039 behaviour is that the latter provides the user with a context menu
2040 (which appears on right clicking the header) allowing to rearrange the
2041 grid columns if CanDragColMove() returns @true. If you want to prevent
2042 this from happening for some reason, you need to define a handler for
2043 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2044 particular doesn't skip the event) as this will prevent the default
2045 right click handling from working.
2046
2047 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2048 generated for the column labels if the native columns header is used

4086 performing several operations with a grid which would otherwise result in

4088
4089 @code
4090 void MyFrame::Foo()

4149 used (as it would catch the events from all the grids). The version with @c
4150 CMD takes the id as first argument and the event handler as the second one
4151 and so can be used with multiple grids as well. Otherwise there are no
4152 difference between the two and only the versions without the id are

4158 string is available from GetString() event object method. This event
4159 can be vetoed if the change is not allowed.
4160 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
4161 @event{EVT_GRID_CELL_CHANGED(func)}
4162 The user changed the data in a cell. The old cell value as string is
4163 available from GetString() event object method. Notice that vetoing
4164 this event still works for backwards compatibility reasons but any new
4165 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4166 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4167 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4168 The user clicked a cell with the left mouse button. Processes a
4169 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4170 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}

4181 @c wxEVT_GRID_EDITOR_HIDDEN event type.

4183 The editor for a cell was shown. Processes a
4184 @c wxEVT_GRID_EDITOR_SHOWN event type.

4186 The user clicked a label with the left mouse button. Processes a
4187 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4188 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4189 The user double-clicked a label with the left mouse button. Processes a
4190 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4191 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4192 The user clicked a label with the right mouse button. Processes a
4193 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4194 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4195 The user double-clicked a label with the right mouse button. Processes
4196 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4197 @event{EVT_GRID_SELECT_CELL(func)}
4198 The given cell was made current, either by user or by the program via a
4199 call to SetGridCursor() or GoToCell(). Processes a
4200 @c wxEVT_GRID_SELECT_CELL event type.
4201 @event{EVT_GRID_COL_MOVE(func)}
4202 The user tries to change the order of the columns in the grid by
4203 dragging the column specified by GetCol(). This event can be vetoed to
4204 either prevent the user from reordering the column change completely
4205 (but notice that if you don't want to allow it at all, you simply
4206 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4207 but handled in some way in the handler, e.g. by really moving the
4208 column to the new position at the associated table level, or allowed to
4209 proceed in which case wxGrid::SetColPos() is used to reorder the
4210 columns display order without affecting the use of the column indices
4211 otherwise.
4212 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4213 @event{EVT_GRID_COL_SORT(func)}
4214 This event is generated when a column is clicked by the user and its
4215 name is explained by the fact that the custom reaction to a click on a
4216 column is to sort the grid contents by this column. However the grid
4217 itself has no special support for sorting and it's up to the handler of
4218 this event to update the associated table. But if the event is handled
4219 (and not vetoed) the grid supposes that the table was indeed resorted
4220 and updates the column to indicate the new sort order and refreshes
4221 itself.
4222 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
