Re: Widget Resize on Mac

[Ben Tupper <btupper(at)bigelow.org>]

Wow!  This is getting quite interesting.  I had taken the liberty of
pestering Pavel for help which he supplied generously.   He tracked the
problem down to my top level base definition which looked like the following:

TLB = Widget_Base(Title = 'Generic Window',$
           column = 1,  /Base_Align_Center, $
           TLB_Size_Events = 1, MBar = MenuID)

Other than the menu bar, the only content of the widget base was a draw
widget.   Pavel suggested that I set Base_Align_Center to zero.  It solved
the problem.

Your solution is interesting because the window is an IDLgrWindow (as opposed
to a Direct Graphics window, unless your Info.mainWindow is a object wrapper
around the Direct Graphics window.)  I think you are resizing the draw_widget
explicity as opposed to resizing the base_widget.   The value 12 is a
surprise because Pavel mentioned that the ever-present Mac window scroll bars
occupy 48 pixels.


Thanks,

Ben
