Loop Function with GUI

7 posts in this topic

Hi All,

This is my first time writing here, and I hope to get some assistant with an issue I'm facing.

I created a GUI window with a button that calls a function in a Loop.

The problem is that I cannot click on anything during the running function even not to close the GUI window.

I'm trying to understand if there is any way to run this function in a loop and still be able to close the windows with the X even though the function is still running.

I understand that I can use the "HotKeySet" but it's not what I'm searching for.

I'm adding a code example of what I'm trying to do that will simulate the process and the problem, in this case I cannot close the window, only from the tray.

Thanks in advance!

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>

Global $FileInput, $listview, $GenButton, $FileInputRead, $Line1, $Line2, $Line3
Call("ListUpdate")
Func ListUpdate()
    GUICreate("",300,300,Default)
    $listview = GUICtrlCreateListView("Test",Default,Default,300,200,$LVS_NOSORTHEADER)
    $Line1 = "Line1"
    $Line2 = "Line2"
    $Line3 = "Line3"
    $GenButton = GUICtrlCreateButton("Show Lines",5,200,200)
    GUISetState()
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GenButton
            _GenList()
    EndSwitch
WEnd
EndFunc
Func _GenList()
        _GUICtrlListView_DeleteAllItems($listview)
        $SetLine = GUICtrlCreateListViewItem($Line1,$listview)
        $SetLine = GUICtrlCreateListViewItem($Line2,$listview)
        $SetLine = GUICtrlCreateListViewItem($Line3,$listview)
        Sleep(5000)
        Call("_GenList")
EndFunc

Thanks for the answer  jaberwocky6669,

I know it's because call(_GenList), i need this loop.

The main idea is to refresh and update this list based on dynamic variables that will change.

But still I want to be able to close this window with the X, or creating more buttons and function that will work in parallel.

DTools,

 

if there is any way to run this function in a loop and still be able to close the windows with the X even though the function is still running

Returning to the initial request, you can do it like this:

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WindowsConstants.au3>
#include <MenuConstants.au3>

Global $fInterrupt = False

$hGUI = GUICreate("Test", 500, 500)

$cButton = GUICtrlCreateButton("Run Func", 10, 10, 80, 30)

GUISetState()

GUIRegisterMsg($WM_SYSCOMMAND, "_WM_SYSCOMMAND")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton
            _Run_Func()
    EndSwitch
WEnd

Func _Run_Func()
    ConsoleWrite("Entering infinite loop" & @CRLF)
    While 1
        Sleep(10)
        If $fInterrupt Then
            ConsoleWrite("Interrupting function" & @CRLF)
            Exit
        EndIf
    WEnd
EndFunc

Func _WM_SYSCOMMAND($hWnd, $iMsg, $wParam, $lParam)
    Switch $wParam
        Case $SC_CLOSE
            ConsoleWrite("[X] clicked" & @CRLF)
            $fInterrupt = True
    EndSwitch
EndFunc

Hi, I Already work with this procedure and it didn't helped in my case, the window was still stuck.

Anyway I found a solution to this issue. (Some workaround)

I Added another combo menu (GUICtrlCreateCombo) to the GUI that can be changed during the running function,
And also few lines in the looping function to check the value in this menu, and stop the loop if needed.

Also I added the HotKeySet to configure "ESC" to exit when the function is running if needed.

Thanks for you help!
