@class wxGrid
wxGrid and its related classes are used for displaying and editing tabular
- data.
- They provide a rich set of features for display, editing, and interacting
- with a variety of data sources. For simple applications, and to 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

explains the relationship between the various grid classes and has a
summary of the keyboard shortcuts and mouse functions provided by wxGrid.
- wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards.
- The new grid classes are reasonably backward-compatible but there are some
- exceptions. There are also easier ways of doing many things compared to the
- previous implementation.
-
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 wxGrid::CreateGrid.

wxGridCellRenderer is the abstract base class for rendereing contents in a
cell. The following renderers are predefined:
- - wxGridCellStringRenderer,
- - wxGridCellBoolRenderer,
- - wxGridCellFloatRenderer,
- - wxGridCellNumberRenderer.
+
+ - 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.
+ 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:
- - wxGridCellTextEditor
- - wxGridCellBoolEditor
- - wxGridCellChoiceEditor
- - wxGridCellNumberEditor.

+ itself has no special support for sorting and it's up to the handler of
