Title: Accessing a Control on Another Dialog
Post by: steezware on August 09, 2023, 06:19:35 PM

So, I'm in a dialog and I want to access/update a control, say a listbox, on the window that spawned the current dialog with focus.

Seems like I used to know how to do this, but maybe it can't even be done?

Thx!

Are you doing a 'goto'(the_window_with_the_control), before trying to access the control?

Figured it out:

PRINT 'SWAP'
LB'Visible = 0 (I passed the LB control value into the new 'process)
PRINT 'SWAP'

Thx for the 'goto' idea but tried 'swap' first and it worked.

It likely would be easier to just use Pseudo control handles.  You can use the *system object to get the handle for any control in the system and then use it anywhere to access the control.

->button 10,@(10,10,10,10)="hello
->osys=new("*system")
->%Btn_handle=osys'Control(10)
->?Btn_handle
 1000100010
