- wxGrid and its related classes are used for displaying and editing tabular data.
+wxGrid and its related classes are used for displaying and editing tabular
+data. wxGrid supports custom attributes for the table cells, allowing to
+completely customize its appearance and uses a separate grid table
+(wxGridTableBase-derived) class for the data management meaning that it
+can be used to display arbitrary amounts of data.

+
+Here is a list of classes related to wxGrid:
+
+@li wxGrid: The main grid control class itself.
+@li wxGridTableBase: The base class for grid data provider.
+@li wxGridStringTable: Simple wxGridTableBase implementation supporting only
+ string data items and storing them all in memory (hence suitable for not
+ too large grids only).
+@li wxGridCellAttr: A cell attribute, allowing to customize its appearance as
+ well as the renderer and editor used for displaying and editing it.
+@li wxGridCellAttrProvider: The object responsible for storing and retrieving
+ the cell attributes.
+@li wxGridColLabelWindow: The window showing the grid columns labels.
+@li wxGridRowLabelWindow: The window showing the grid rows labels.
+@li wxGridCornerLabelWindow: The window used in the upper left grid corner.
+@li wxGridWindow: The window representing the main part of the grid.
+@li wxGridCellRenderer: Base class for objects used to display a cell value.
+@li wxGridCellStringRenderer: Renderer showing the cell as a text string.
+@li wxGridCellNumberRenderer: Renderer showing the cell as an integer number.
+@li wxGridCellFloatRenderer: Renderer showing the cell as a floating point
+ number.
+@li wxGridCellBoolRenderer: Renderer showing the cell as checked or unchecked
+ box.
+@li wxGridCellEditor: Base class for objects used to edit the cell value.
+@li wxGridCellStringEditor: Editor for cells containing text strings.
+@li wxGridCellNumberEditor: Editor for cells containing integer numbers.
+@li wxGridCellFloatEditor: Editor for cells containing floating point numbers.
+@li wxGridCellBoolEditor: Editor for boolean-valued cells.
+@li wxGridCellChoiceEditor: Editor allowing to choose one of the predefined
+ strings (and possibly enter new one).
+@li wxGridEvent: The event sent by most of wxGrid actions.
+@li wxGridSizeEvent: The special event sent when a grid column or row is
+ resized.
+@li wxGridRangeSelectEvent: The special event sent when a range of cells is
+ selected in the grid.
+@li wxGridEditorCreatedEvent: The special event sent when a cell editor is
+ created.
+@li wxGridSelection: The object efficiently representing the grid selection.
+@li wxGridTypeRegistry: Contains information about the data types supported by
+ the grid.

+@section overview_grid_resizing Column and row sizes
+
+@b NB: This section will discuss the resizing of wxGrid rows only to avoid
+repetitions but everything in it also applies to grid columns, just replace @c
+Row in the method names with @c Col.
+
+Initially all wxGrid rows have the same height, which can be modified for all
+of them at once using wxGrid::SetDefaultRowSize(). However, unlike simpler
+controls such as wxListBox or wxListCtrl, wxGrid also allows its rows to be
+individually resized to have their own height using wxGrid::SetRowSize() (as a
+special case, a row may be hidden entirely by setting its size to 0, which is
+done by a helper wxGrid::HideRow() method). It is also possible to resize a row
+to fit its contents with wxGrid::AutoSizeRow() or do it for all rows at once
+with wxGrid::AutoSizeRows().
+
+Additionally, by default the user can also drag the row separator lines to
+resize the rows interactively. This can be forbidden completely by calling
+wxGrid::DisableDragRowSize() or just for the individual rows using
+wxGrid::DisableRowResize().
+
+If you do allow the user to resize the grid rows, it may be a good idea to save
+their heights and restore it when the grid is recreated the next time (possibly
+during a next program execution): the functions wxGrid::GetRowSizes() and
+wxGrid::SetRowSizes() can help with this, you will just need to serialize
+wxGridSizesInfo structure returned by the former in some way and deserialize it
+back before calling the latter.
