Forms & Screen
How to I make something Resize when the _SCREEN.Resize event fires?
Posted: 12 Nov 02 (Edited 10 Oct 03)
This has been tackled in a number of ways... the most common being creating a timer on the child form that repeatedly checks to see if _SCREEN.Height and _SCREEN.Width have changed.
VFP8's BINDEVENT() probably is going to be the "Documented" way of doing this.
Update: VFP8 SP1 Deliberately disables the method of hooking the _SCREEN events described here due to instability of VFP when using this method.
However, still, the most elegant and simplest method I've seen is best demonstrated with code:
*Credit for this method must be given to the following:

*with thanks to "Michel Roy" firstname.lastname@example.org from the
*News Group microsoft.public.fox.programmer.exchange
* In your main program:
DEFINE CLASS Resizer AS Custom
oScreen = _Screen
KeyPreview = .t.
WAIT window "Resizing" NOWAIT
FUNCTION oScr.Click && Works
WAIT WINDOW NOWAIT "_SCREEN.Click"
FUNCTION oScr.DblClick && Works
* Note that Click fires first!
WAIT WINDOW NOWAIT "_SCREEN.DblClick"
PROCEDURE oScr.KeyPress && Works
LPARAMETERS nKeyCode, nShiftStat, nKeyCode, nShiftStat
NODEFAULT && Hmmm, doesn't work like a form's does.
WAIT WINDOW NOWAIT "QueryUnload!"
PROCEDURE oScr.RightClick && Works
PROCEDURE oScr.MyMethod && Works
* This fires on _SCREEN.MyMethod() !!
wait window "my method fired!"
