1223 wxGrid and its related classes are used for displaying and editing tabular
1224 data.
1225 They provide a rich set of features for display, editing, and interacting
1226 with a variety of data sources. For simple applications, and to help you
1227 get started, wxGrid is the only class you need to refer to directly. It
1228 will set up default instances of the other classes and manage them for you.
1229 For more complex applications you can derive your own classes for custom
1230 grid views, grid data tables, cell editors and renderers. The @ref
1231 overview_grid "wxGrid overview" has examples of simple and more complex applications,
1232 explains the relationship between the various grid classes and has a
1233 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1234
1235 wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards.
1236 The new grid classes are reasonably backward-compatible but there are some
1237 exceptions. There are also easier ways of doing many things compared to the
1238 previous implementation.
1239
1240 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1241 class. One or more wxGrid classes may act as a view for one table class.
1242 The default table class is called wxGridStringTable and holds an array of
1243 strings. An instance of such a class is created by wxGrid::CreateGrid.
1244
1245 wxGridCellRenderer is the abstract base class for rendereing contents in a
1246 cell. The following renderers are predefined:
1247 - wxGridCellStringRenderer,
1248 - wxGridCellBoolRenderer,
1249 - wxGridCellFloatRenderer,
1250 - wxGridCellNumberRenderer.
1251 The look of a cell can be further defined using wxGridCellAttr. An object
1252 of this type may be returned by wxGridTableBase::GetAttr.
1253
1254 wxGridCellEditor is the abstract base class for editing the value of a
1255 cell. The following editors are predefined:
1256 - wxGridCellTextEditor
1257 - wxGridCellBoolEditor
1258 - wxGridCellChoiceEditor
1259 - wxGridCellNumberEditor.
