Need help on using GUIonEventMode <solved>

5 posts in this topic

#1 ·  Posted (edited)

hello guys, i'm trying to add buttons on my program so that add features can control the process,it seem GuiOnEventMode is the best choice for my program,the follows are main parts of my program included four functions work for me very well if not put them together,can someone point out where i am wrong or there is better way to handle this,thanks in advance.

#include <array.au3>
#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>

$MainGUI = GUICreate("Test", 220, 115)
$progressbar = GUICtrlCreateProgress(10, 10, 200, 20)
$btn1 = GUICtrlCreateButton("Run", 160, 91, 50, 20)
$btn2 = GUICtrlCreateButton("Suspend", 10, 35, 50, 20)
$btn3 = GUICtrlCreateButton("Resume", 10, 63, 50, 20)
$btn4 = GUICtrlCreateButton("Terminate", 10, 91, 50, 20)
Opt("GUIOnEventMode", 1)
GUISetState()
    GUISetOnEvent($GUI_EVENT_CLOSE, "_Main")
    GUICtrlSetOnEvent($btn1, "_Main")
    GUICtrlSetOnEvent($btn2, "_Main")
    GUICtrlSetOnEvent($btn3, "_Main")
    GUICtrlSetOnEvent($btn4, "_Main")

While 1

            EndIf

lhw,

Are you asking why the "Suspend", "Resume" and "Terminate" buttons do not work while the process is running? :unsure:

If so, this is becasue you remain in the _GetPIOData function until the 7z process ends and other functions will not run until you return to the idle loop. :>

Look at the Interrupting a running function tutorial in the Wiki to learn a number of ways to get around this. ;)
