WM_KEYDOWN with GuiRegisterMsg work only with empty GUI?

3 posts in this topic

Hi all,

I trying to register message WM_KEYDOWN, but it seems that it works only if the GUI is free of Controls... as soon as you create any(?) control, the function not responding anymore:

Global Const $WM_KEYDOWN = 0x0101

$HWnd = GUICreate("KEYDOWN_TEST",400,300)
GUIRegisterMsg($WM_KEYDOWN, "Get_KeyDown")

;$BUTTON = GUICtrlCreateButton("Button",10,10,50,20)

GUISetState()


While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case -3
            Exit
    EndSwitch
WEnd

Func Get_KeyDown($HWnd,$Msg,$wParam,$lParam)
    MsgBox(262144, "", "Code of pressed Key is: " & BitAND($wParam,0xFF))
EndFuncoÝ÷ ÙIÜ¢iÛax­¶Ü­æ­åwܨ»¥Ç¶­~éܶ*'jYb!zyÊ+)­ë,yÒ ¹ë"ajÛaȬmçºÇ­æî¶Ú'«-çèrëÛayc

But why this behaviour? is this a bug of the GuiRegistrMsg, or it is an expecting behaviour of the WM_KEYDOWN message? then why we need it, create controls after GuiSetState is not so practical solution, the user will see "creation process" if there is too many controls.

Ok, i think i found my answer in the help file:

Some controls consume internally specific Windows Message ID, so registrating them will have no effect, e.g; WM_CHAR, WM_KEYDOWN, WM_KEYUP are consumed by an edit control.

To bad :)

I've seen some cases where control events are allowed to cascade down to the container control. Is that just .Net or does that work outside .Net too?
