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.

1000 Class providing attributes to be used for the grid cells.
1001
1002 This class both defines an interface which grid cell attributes providers
1003 should implement -- and which can be implemented differently in derived
1004 classes -- and a default implementation of this interface which is often
1005 good enough to be used without modification, especially with not very large
1006 grids for which the efficiency of attributes storage hardly matters (see
1007 the discussion below).
1008
1009 An object of this class can be associated with a wxGrid using
1010 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1011 intend to use the default provider as it is used by wxGridTableBase by
1012 default anyhow.
1013
1014 Notice that while attributes provided by this class can be set for
1015 individual cells using SetAttr() or the entire rows or columns using
1016 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1017 function.
1018
1019
1020 The default implementation of this class stores the attributes passed to
1021 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1022 derived class may use its knowledge about how the attributes are used in
1023 your program to implement it much more efficiently: for example, using a
1024 special background colour for all even-numbered rows can be implemented by
1025 simply returning the same attribute from GetAttr() if the row number is
1026 even instead of having to store N/2 row attributes where N is the total
1027 number of rows in the grid.

1608
1609 wxGrid and its related classes are used for displaying and editing tabular
1610 data. They provide a rich set of features for display, editing, and
1611 interacting with a variety of data sources. For simple applications, and to
1612 help you get started, wxGrid is the only class you need to refer to
1613 directly. It will set up default instances of the other classes and manage
1614 them for you. For more complex applications you can derive your own classes
1615 for custom grid views, grid data tables, cell editors and renderers. The
1616 @ref overview_grid has examples of simple and more complex applications,
1617 explains the relationship between the various grid classes and has a
1618 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1619
1620 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1621 class. One or more wxGrid classes may act as a view for one table class.
1622 The default table class is called wxGridStringTable and holds an array of
1623 strings. An instance of such a class is created by CreateGrid().
1624
1625 wxGridCellRenderer is the abstract base class for rendereing contents in a
1626 cell. The following renderers are predefined:
1627
1628 - wxGridCellBoolRenderer
1629 - wxGridCellFloatRenderer
1630 - wxGridCellNumberRenderer
1631 - wxGridCellStringRenderer
1632
1633 The look of a cell can be further defined using wxGridCellAttr. An object
1634 of this type may be returned by wxGridTableBase::GetAttr().
1635
1636 wxGridCellEditor is the abstract base class for editing the value of a
1637 cell. The following editors are predefined:
1638
1639 - wxGridCellBoolEditor
1640 - wxGridCellChoiceEditor
1641 - wxGridCellFloatEditor
1642 - wxGridCellNumberEditor
1643 - wxGridCellTextEditor
1644

1646 wxGridEditorCreatedEvent for the documentation of all event types you can
1647 use with wxGrid.

2002 If this function is called with @true argument, a wxHeaderCtrl is used
2003 instead to display the column labels instead of drawing them in wxGrid
2004 code itself. This has the advantage of making the grid look and feel
2005 perfectly the same as native applications (using SetUseNativeColLabels()
2006 the grid can be made to look more natively but it still doesn't feel
2007 natively, notably the column resizing and dragging still works slightly
2008 differently as it is implemented in wxWidgets itself) but results in
2009 different behaviour for column and row headers, for which there is no
2010 equivalent function, and, most importantly, is unsuitable for grids
2011 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2012 mode. Because of this, by default the grid does not use the native
2013 header control but you should call this function to enable it if you
2014 are using the grid to display tabular data and don't have thousands of

4031 wxGrid::EndBatch() in its destructor. It is typically used in a function
4032 performing several operations with a grid which would otherwise result in
4033 flicker. For example:
4034
4035 @code
4036 void MyFrame::Foo()
4037 {
4038 m_grid = new wxGrid(this, ...);
4039

4043 m_grid-AppendRow();
4044
4045 // destructor called, grid refreshed
4046 }
4047 @endcode
4048
4049 Using this class is easier and safer than calling wxGrid::BeginBatch() and

4095 used (as it would catch the events from all the grids). The version with @c
4096 CMD takes the id as first argument and the event handler as the second one
4097 and so can be used with multiple grids as well. Otherwise there are no
4098 difference between the two and only the versions without the id are
4099 documented below for brevity.
4100
4101 @beginEventTable{wxGridEvent}
4102 @event{EVT_GRID_CELL_CHANGING(func)}
4103 The user is about to change the data in a cell. The new cell value as
4104 string is available from GetString() event object method. This event
4105 can be vetoed if the change is not allowed.
4106 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
4107 @event{EVT_GRID_CELL_CHANGED(func)}
4108 The user changed the data in a cell. The old cell value as string is
4109 available from GetString() event object method. Notice that vetoing
4110 this event still works for backwards compatibility reasons but any new
4111 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4112 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4113 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4114 The user clicked a cell with the left mouse button. Processes a
4115 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4116 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
4117 The user double-clicked a cell with the left mouse button. Processes a
4118 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
4119 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}

4121 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.

4123 The user double-clicked a cell with the right mouse button. Processes a
4124 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
4125 @event{EVT_GRID_EDITOR_HIDDEN(func)}
4126 The editor for a cell was hidden. Processes a
4127 @c wxEVT_GRID_EDITOR_HIDDEN event type.
4128 @event{EVT_GRID_EDITOR_SHOWN(func)}
4129 The editor for a cell was shown. Processes a
4130 @c wxEVT_GRID_EDITOR_SHOWN event type.
4131 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
4132 The user clicked a label with the left mouse button. Processes a
4133 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4134 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4135 The user double-clicked a label with the left mouse button. Processes a
4136 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4137 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4138 The user clicked a label with the right mouse button. Processes a
4139 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4140 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4141 The user double-clicked a label with the right mouse button. Processes
4142 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4143 @event{EVT_GRID_SELECT_CELL(func)}
4144 The given cell was made current, either by user or by the program via a
4145 call to SetGridCursor() or GoToCell(). Processes a
4146 @c wxEVT_GRID_SELECT_CELL event type.
4147 @event{EVT_GRID_COL_MOVE(func)}
4148 The user tries to change the order of the columns in the grid by
4149 dragging the column specified by GetCol(). This event can be vetoed to
4150 either prevent the user from reordering the column change completely
4151 (but notice that if you don't want to allow it at all, you simply
4152 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4153 but handled in some way in the handler, e.g. by really moving the
4154 column to the new position at the associated table level, or allowed to
4155 proceed in which case wxGrid::SetColPos() is used to reorder the
4156 columns display order without affecting the use of the column indices
4157 otherwise.
4158 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4159 @event{EVT_GRID_COL_SORT(func)}
4160 This event is generated when a column is clicked by the user and its
4161 name is explained by the fact that the custom reaction to a click on a
4162 column is to sort the grid contents by this column. However the grid
4163 itself has no special support for sorting and it's up to the handler of
4164 this event to update the associated table. But if the event is handled
4165 (and not vetoed) the grid supposes that the table was indeed resorted
4166 and updates the column to indicate the new sort order and refreshes
4167 itself.
4168 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
