1227 wxGrid and its related classes are used for displaying and editing tabular
1228 data.
1229 They provide a rich set of features for display, editing, and interacting
1230 with a variety of data sources. For simple applications, and to help you
1231 get started, wxGrid is the only class you need to refer to directly. It
1232 will set up default instances of the other classes and manage them for you.
1233 For more complex applications you can derive your own classes for custom
1234 grid views, grid data tables, cell editors and renderers. The @ref
1235 overview_grid "wxGrid overview" has examples of simple and more complex applications,
1236 explains the relationship between the various grid classes and has a
1237 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1238
1239 wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards.
1240 The new grid classes are reasonably backward-compatible but there are some
1241 exceptions. There are also easier ways of doing many things compared to the
1242 previous implementation.
1243
1244 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1245 class. One or more wxGrid classes may act as a view for one table class.
1246 The default table class is called wxGridStringTable and holds an array of
1247 strings. An instance of such a class is created by wxGrid::CreateGrid.
1248
1249 wxGridCellRenderer is the abstract base class for rendereing contents in a
1250 cell. The following renderers are predefined:
1251 - wxGridCellStringRenderer,
1252 - wxGridCellBoolRenderer,
1253 - wxGridCellFloatRenderer,
1254 - wxGridCellNumberRenderer.
1255 The look of a cell can be further defined using wxGridCellAttr. An object
1256 of this type may be returned by wxGridTableBase::GetAttr.
1257
1258 wxGridCellEditor is the abstract base class for editing the value of a
1259 cell. The following editors are predefined:
1260 - wxGridCellTextEditor
1261 - wxGridCellBoolEditor
1262 - wxGridCellChoiceEditor
1263 - wxGridCellNumberEditor.
