Keyword Parameters

CANCEL: An output parameter. If the user kills the widget or clicks the Cancel
button this keyword is set to 1. It is set to 0 otherwise. It
allows you to determine if the user canceled the dialog without
having to check the validity of the answer.

IF cancelled THEN Return
GRID: A two-element array [xsize, ysize] with the initial parameters for the widget.
GROUP_LEADER: The widget ID of the group leader of this pop-up
dialog. This should be provided if you are calling
the program from within a widget program:
thetext = GridSize(Group_Leader=event.top)
If a group leader is not provided, an unmapped top-level base widget
will be created as a group leader.

Outputs

theGrid: A two-element array of the grid size [xsize, ysize].
