- wxGrid and its related classes are used for displaying and editing tabular

- 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 "wxGrid overview" 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.
+ /**
+ Makes the grid globally editable or read-only.
- 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.
+ If the edit argument is @false this function sets the whole grid as
+ read-only. If the argument is @true the grid is set to the default
+ state where cells may be editable. In the default state you can set
+ single grid cells and whole rows and columns to be editable or
+ read-only via wxGridCellAttr::SetReadOnly(). For single cells you
+ can also use the shortcut function SetReadOnly().
- 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

+ otherwise.
+ This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.

+ This event is generated when a column is clicked by the user and its

+ itself has no special support for sorting and it's up to the handler of
+ this event to update the associated table. But if the event is handled
+ (and not vetoed) the grid supposes that the table was indeed resorted

- This small class can be used to prevent wxGrid from redrawing
- during its lifetime by calling wxGrid::BeginBatch
- in its constructor and wxGrid::EndBatch in its
- destructor. It is typically used in a function performing several operations
- with a grid which would otherwise result in flicker. For example:
-
- @code
- void MyFrame::Foo()
- {
- m_grid = new wxGrid(this, ...);
-
- wxGridUpdateLocker noUpdates(m_grid);
- m_grid-AppendColumn();

- m_grid-AppendRow();

+ */

- Using this class is easier and safer than calling
