+ @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 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
+
+ Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and
+ wxGridEditorCreatedEvent for the documentation of all event types you can
+ use with wxGrid.
