+ classes -- and a default implementation of this interface which is often
+ good enough to be used without modification, especially with not very large
+ grids for which the efficiency of attributes storage hardly matters (see
+ the discussion below).
+
+ An object of this class can be associated with a wxGrid using
+ wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
+ intend to use the default provider as it is used by wxGridTableBase by
+ default anyhow.
+
+ Notice that while attributes provided by this class can be set for
+ individual cells using SetAttr() or the entire rows or columns using
+ SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
+ function.
+
+
+ The default implementation of this class stores the attributes passed to
+ its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
+ derived class may use its knowledge about how the attributes are used in
+ your program to implement it much more efficiently: for example, using a
+ special background colour for all even-numbered rows can be implemented by
+ simply returning the same attribute from GetAttr() if the row number is
+ even instead of having to store N/2 row attributes where N is the total
+ number of rows in the grid.
+
+ Notice that objects of this class can't be copied.

+ help you get started, wxGrid is the only class you need to refer to
+ directly. It will set up default instances of the other classes and manage
+ them for you. For more complex applications you can derive your own classes
+ for custom grid views, grid data tables, cell editors and renderers. The
+ @ref overview_grid has examples of simple and more complex applications,
+ explains the relationship between the various grid classes and has a
+ summary of the keyboard shortcuts and mouse functions provided by wxGrid.
+
+ A wxGridTableBase class holds the actual data to be displayed by a wxGrid
+ class. One or more wxGrid classes may act as a view for one table class.
+ The default table class is called wxGridStringTable and holds an array of
+ strings. An instance of such a class is created by CreateGrid().
+
+ wxGridCellRenderer is the abstract base class for rendering contents in a
+ cell. The following renderers are predefined:
+
+ - wxGridCellBoolRenderer
+ - wxGridCellFloatRenderer
+ - wxGridCellNumberRenderer
+ - wxGridCellStringRenderer
+
+ The look of a cell can be further defined using wxGridCellAttr. An object
+ of this type may be returned by wxGridTableBase::GetAttr().
+
+ wxGridCellEditor is the abstract base class for editing the value of a
+ cell. The following editors are predefined:
+
+ - wxGridCellBoolEditor
+ - wxGridCellChoiceEditor
+ - wxGridCellFloatEditor
+ - wxGridCellNumberEditor
+ - wxGridCellTextEditor

- Register a new data type.
+ Invalidates the cached attribute for the given cell.
- The data types allow to naturally associate specific renderers and
- editors to the cells containing values of the given type. For example,
- the grid automatically registers a data type with the name @c
- wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
- wxGridCellTextEditor as its renderer and editor respectively -- this is
- the data type used by all the cells of the default wxGridStringTable,
- so this renderer and editor are used by default for all grid cells.
-
- However if a custom table returns @c wxGRID_VALUE_BOOL from its
- wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
- wxGridCellBoolEditor are used for it because the grid also registers a
- boolean data type with this name.
+ For efficiency reasons, wxGrid may cache the recently used attributes
+ (currently it caches only the single most recently used one, in fact)
+ which can result in the cell appearance not being refreshed even when
+ the attribute returned by your custom wxGridCellAttrProvider-derived
+ class has changed. To force the grid to refresh the cell attribute,
+ this function may be used. Notice that calling it will not result in
+ actually redrawing the cell, you still need to call
+ wxWindow::RefreshRect() to invalidate the area occupied by the cell in
+ the window to do this. Also note that you don't need to call this
+ function if you store the attributes in wxGrid itself, i.e. use its
+ SetAttr() and similar methods, it is only useful when using a separate
+ custom attributes provider.

- data types using your own custom renderers and editors. Just remember
- that the table must identify a cell as being of the given type for them

+ this event to update the associated table. But if the event is handled
+ (and not vetoed) the grid supposes that the table was indeed resorted
+ and updates the column to indicate the new sort order and refreshes
+ itself.
+ This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
