Multiple GUIs and GUIRegisterMsg()

4 posts in this topic

Hi, I have 2 GUIs, I need to be able to know when my mouse is clicked on one or the other. I'm registering the $WM_LBUTTONDOWN message and I thought with a switch on the GUI handlers I could achieve that but it ain't working. Any tip on this please ?

GUIRegisterMsg($WM_LBUTTONDOWN, "_WM_LBUTTONDOWN")

Func _WM_LBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    Local Const $SC_DRAGMOVE = 0xF012

    Switch $hWnd
        Case $hGUI
            _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
        Case $hGUI_Secondary
            ConsoleWrite("secondary GUI is clicked")
    EndSwitch

EndFunc

A click (hold) on the main GUI allows to move it by dragging, no issue.

A click on the 2nd GUI ... doesn't trigger anything, no message displayed in the console.

No idea why.

dom3787,

Works perfectly for me: :)

#include <GUIConstantsEx.au3>
#include <Constants.au3>
#include <WindowsConstants.au3>
#include <SendMessage.au3>

$hGUI = GUICreate("Test", 200, 200, 100, 100)
GUISetState()

$hGUI_Secondary = GUICreate("Test 2", 200, 200, 300, 300)
GUISetState()

GUIRegisterMsg($WM_LBUTTONDOWN, "_WM_LBUTTONDOWN")

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

Func _WM_LBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    Local Const $SC_DRAGMOVE = 0xF012
    Switch $hWnd
        Case $hGUI
           _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
        Case $hGUI_Secondary
           ConsoleWrite("secondary GUI is clicked" & @CRLF)
    EndSwitch
EndFunc

P.S. Posting runnable code rather then snippets is always a good idea. ;)

Yep I found it while trying to solve my issue, wasn't helpful. I just found out the reason for it not to work though, still a bit wondering how to get that going as I want. The 2ndary GUI was filled with transparent label on all it's surface, thus when click on it, I, in fact, click on the Label which is on it and that message isn't triggered.

edit : my code is hundreds of lines and a bunch of includes so I'm trying to strip it to the minimum, which was in fact here, lacking the gui declarations and their controls over them (especially that label ^^)

Typical situation by the way, I'm not super familiar with GUIRegisterMsg() so that even if the code seemed ok, my eyes were on it for a long time, trying to find why it wasn't working, maybe of some misunderstanding on my part, whereas, in fact, the problem had it's origin on a totally different area which was the nature of the GUI and how it was made, here, completely covered with the label so that no background gui pixel was accessible to get that message triggered!
