G-label not running for multi-line Edit control

[Scoox]

Please test the following code. In this example the two Edit controls are identical except that Edit2 is multi-row while Edit1 isn't. When Button is clicked, both edit controls are cleared, which should launch both Edit1() and Edit2(); in practice, only Edit1() is launched.

Code: Select all

#NoEnv
#SingleInstance Force

Gui, Add, Edit, vEdit1 gEdit1 r1
Gui, Add, Edit, vEdit2 gEdit2 r2 ;change this to r1
Gui, Add, Button, vButton gButton, Clear boxes
Gui, Show
Return

Button()
{
	GuiControl,, Edit1
	GuiControl,, Edit2
}

Edit1()
{
	SoundBeep, 1000, 200
}

Edit2()
{
	SoundBeep, 2000, 200
}

GuiClose()
{
	ExitApp
}

Thank you

A g-label such as gMySubroutine may be listed in the control's options. This would cause the MySubroutine label to be launched automatically whenever the user or the script changes the contents of the control.

The EN_CHANGE notification code is not sent when the ES_MULTILINE style is used and the text is sent through WM_SETTEXT.

I.e. AHK isn't notified of the change. AHK would need to post the notification by itself when processing the GuiControl command.

Thank you, that at least explains it. So basically this is a feature? Wouldn't it be beneficial if single-line and multi-line both worked the same way? I'm not a programmer so I don't know the technical reasons behind this limitation, but as a newbie I scratched my head quite a while over this one, especially since there was no mention in the help. I really appreciate your responses, really helpful, cheers!
