@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_gridoverview 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.
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.
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 wxGrid::CreateGrid.
wxGridCellRenderer is the abstract base
class for rendereing contents in a cell. The following renderers are
predefined:
wxGridCellStringRenderer,
wxGridCellBoolRenderer,
wxGridCellFloatRenderer,
wxGridCellNumberRenderer. 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:
wxGridCellTextEditor
wxGridCellBoolEditor
wxGridCellChoiceEditor
wxGridCellNumberEditor.

@class wxGridUpdateLocker
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();
... many other operations with m_grid...
m_grid-AppendRow();
// destructor called, grid refreshed
}

Using this class is easier and safer than calling
