Event handler question

Recommended Posts

Hi guys, I'm trying to understand the event handler.  It seems like if there is a sleep/loop at the base level (i.e. not inside a function) then the event handler triggers, but a sleep/loop in a function stops the event handler triggering.  How does AutoIt handle this sort of thing.  Here's my test code, it creates two buttons both with event handlers. Once the 'test' function is invoked, the time event doesn't trigger.  If the test function is not invoked then the time function does trigger.  What's the logic behind that?

#include <guiconstants.au3>
Opt("GuiOnEventMode", True)
GUICreate("Test GUI", 200, 100, 100, 100)
$mGUI_ButtonTime = GUICtrlCreateButton("Time", 30, 10, 50, 26)
GUICtrlSetOnEvent($mGUI_ButtonTime, "TimeFunction")
$mGUI_ButtonTest = GUICtrlCreateButton("Test", 30, 50, 50, 26)
GUICtrlSetOnEvent($mGUI_ButtonTest, "TestFunction")

While 1
   Sleep(100)        ; events work while sleeping at this level

Func TimeFunction()
   ConsoleWrite(@HOUR & ":" & @MIN & ":" & @SEC & ": Time" & @CRLF)

Func TestFunction()
   ConsoleWrite(@HOUR & ":" & @MIN & ":" & @SEC & ": Test" & @CRLF)

   While 1
      Sleep(100)        ; events DON'T work while sleeping at this level

Welcome to the AutoIt forums.

Correct, AutoIt will not run another function if it is still occupied within an earlier call. I recommend reading the Interrupting a running function tutorial in the Wiki to get more information about this.  The obvious solution is to return t the main script rather then remain within a function - but the tutorial does show how you can work around this.

And when you post code please use Code tags - see here how to do it.  Then you get a scrolling box and syntax colouring as you can see above now I have added the tags.
