Events handling : event is not detected

Recommended Posts

Hi all,

I've been trying to find why the cript below doesn't work for some time... It's probably obvious but it puzzles me.

#include-once


#include <GUIConstantsEx.au3>


global $exitCountdown = false
global $windows[256]
global $windowOnTop = 1


Func MakeModal($windowHandle)
    $windows[$windowOnTop] = $windowHandle

    if $windowOnTop>1 then ; do that for all windows except the main window (i.e. the first one)
        GUISetState(@SW_DISABLE, $windows[$windowOnTop-1]) ; disable current
        GUISetOnEvent($GUI_EVENT_CLOSE, 'CloseModal', $windowHandle)
        GUISwitch($windowHandle)    ; switch to the new modal window        
        GUISetState(@SW_SHOW, $windowHandle)
    EndIf
    
    If $windowOnTop < 255 then 
        $windowOnTop = $windowOnTop + 1
    Else
        MsgBox(0, 'Error', 'Too many modal windows')
    EndIf
EndFunc

Func CloseModal()
    if $windowOnTop > 2 then ; we need at least 2 windows (the main one and a modal)
        $windowOnTop  = $windowOnTop-1

        GUISetState(@SW_HIDE, $windows[$windowOnTop]) ; hide the modal
        GUIDelete($windows[$windowOnTop]) ; destroy the modal
        $windows[$windowOnTop] = -1 ;security
        GUISetState(@SW_ENABLE, $windows[$windowOnTop-1]) ; enable window below
        
        GUISwitch($windows[$windowOnTop-1]) ; switch to the previous
        GUISetState(@SW_SHOW, $windows[$windowOnTop-1])
        
        WinActivate($windows[$windowOnTop-1])
    EndIf
EndFunc
        
    
Func GUI_OnGiveControl()
    ConsoleWrite("Click"&@CRLF)
    $exitCountdown = true
EndFunc



func CreatePopupWindow()
    $frmNoControl = GUICreate(" ", 283, 100, 450, 219)
    $btnGiveControl = GUICtrlCreateButton("", 8, 10, 265, 33, 0)
    GUISetState(@SW_SHOW)   
    MakeModal($frmNoControl)
    
    GUISwitch($frmNoControl)
    GUICtrlSetOnEvent($btnGiveControl, 'GUI_OnGiveControl')
    
    GUISetState(@SW_SHOW)

    $countDown = 15 ;15 secs
    $exitCountdown = false
    while not $exitCountdown
        GUICtrlSetData($btnGiveControl, "Discarding this window in ... "&$countDown&"s")

        if $countDown > 0 then 
            $countDown -= 1
        Else
            $exitCountdown = True
        EndIf

        GUISwitch($frmNoControl)
        ConsoleWrite("Discard window is active"&@CRLF)
        
        Sleep (1000)

    WEnd

    CloseModal()
EndFunc




Func Stalk_CloseApplication()
    Exit
EndFunc

Func Stalk_OnOK()
    CreatePopupWindow()
EndFunc

Func CreateMainWindow()
    $title = "Test Stalk"
    $frmTest = GUICreate($title,150, 150, 600, 400)
    ConsoleWrite("$frmTest: "&$frmTest&@CRLF)
    GUISwitch($frmTest)
    $btnStalk_OK = GUICtrlCreateButton("Go", 0, 0, 150, 150, 0)
    GUISetState(@SW_SHOW)
    #EndRegion ### END Koda GUI section ###

    MakeModal($frmTest)
    GUISetState(@SW_SHOW)

    GUISetOnEvent($GUI_EVENT_CLOSE, 'Stalk_CloseApplication')
    GUICtrlSetOnEvent($btnStalk_OK, 'Stalk_OnOK')
    ConsoleWrite("Main created."&@CRLF)

EndFunc


Func MainFunc()
    
    Opt("GUIOnEventMode", 1)
    Opt("TrayIconDebug", 1)

    ConsoleWrite("Start."&@CRLF)

    CreateMainWindow()

    While 1
        Sleep(1000)
        ConsoleWrite("Main3"&@CRLF)
    WEnd

EndFunc


MainFunc()

As you can see if you run the script, the popup window won't close if you click on the button.

The event seems not to be detected.

I suspect it's because the wrong GUI is active at that time, but I can't solve the issue.

Can someone help me?

Hi..

Your while loop in CreatePopupWindow() function is executed continously, thats why the GUI events aren't registered. As autoit doesn't support multithreading, it can't do two things simultaneously.

It can't do two things simultaneously.

Simultaneously to what? It kinda replaces the main loop and shouldn't prevent the event to be fired...

What would be the best way to proceed, then?

Oh I think I got it.

- Every time an event is fired, then it's queued.

- An event cannot be dequeued until the whole script fired by the previous event has been executed.

- When I click on "Go", it triggers an event, and, because of the way my code is written, the popup window's loop is part of that "event" code.

- Therefore, any action performed while I'm still displaying that window *cannot* be unqueued.

I'll try to change the code to fix that.

See once the script goes into the while loop.. it will continue counting down till your 15 secs are up and $exitCountdown is set to true.. Till this time it won't do anything else..

I would change things around here.. But I still am not exactly sure what u wanna do.. So pls explain in simple terms what u want the script to do..
