GridView (gb.qt4)

Implements a control that displays data in a grid.

You can fill the grid explicitly, or implement the Data event to display the grid contents on demand.

You should use the last method if you have a lot of rows to display. The control can handle millions of lines gracefully.

This class inherits UserControl.

This class is creatable.

This class acts like a read-only array.
