When to refresh?

[typhoon]

When I use the Graphic control, nothing shows up unless I click off the window and then click back to it. Are manual refreshes necessary to make graphics show up while having the script gui on top?

Supply a short script that can reproduce the problem, and we should be able to help resolve the problem.

do a search for +dllcall+InvalidateRect*

$graphic = GUICtrlCreateGraphic(0, 0, 100, 100)
GUICtrlSetBkColor($graphic, 0xffffff)

while 1
; main loop
wend

So, what happens is that I just want the background color to show up (to highlight the graphic box from the rest of the gray window). This doesn't happen when the script runs, only when I click off and then back onto the script gui.

works for me with 3.2.0.1 and beta 3.2.1.13

#include <GUIConstants.au3>

GUICreate('test', 150, 125)

Opt("GUIOnEventMode", 1)
GUISetOnEvent($GUI_EVENT_CLOSE, "ExitScript")

$graphic = GUICtrlCreateGraphic(0, 0, 100, 100)
GUICtrlSetBkColor($graphic, 0xffffff)

GUISetState()

While 1
    Sleep(5000)
WEnd

Func ExitScript()
    Exit
EndFunc

Huh. After playing around with it a bit, it seems like the problem was that I was showing the main GUI window before adding the Graphic control (adding it before showing the main window makes it ok, I guess because there is an implicit repaint). Strange though, because I also added Input controls after showing the main window and they show up without needing a manual refresh. Seems like this is varying from one control to another.

Ok, well it seems that after drawing to the control (after showing the initial state), it still fails to refresh automatically unless the window is clicked off. I am drawing Pixels if that makes any difference.

I suppose you would have had an solution by now if you prepared your question a little bit with some working code. Just throwing out unprepared questions are futile.

Wish you the best of luck with your code

Look at GUICtrlSetGraphic() & $GUI_GR_REFRESH in HelpFile

Make it click on the desktop, then on the taskbar or just make it open the window.

Nonsense, no need to do something like that.
