Unbind hotkey on GUI control

[PumpkinShortie]

I am using a Hotkey box in a GUI and I want to use a button or something to unset the hotkey.

This is what I have :

Code: Select all

Gui, Add, Hotkey, x110 y30 w190 h21 vstartTaxiHotkey, Hotkey
Gui, Add, Button, x310 y29 w43 h23 gunsetStartTaxiHotkey, Unset
[...]
    
unsetStartTaxiHotkey:
    vstopTaxiHotkey := None
    Return

But I don't know what to set the value to nor how to make the text in the box update.

Code: Select all

unsetStartTaxiHotkey:
    startTaxiHotkey =
	GuiControl,,startTaxiHotkey
Return

Okay this works, but can you enlighten me as to why putting

Code: Select all

startTaxiHotkey = GuiControl,,startTaxiHotkey

on the same line does not work?

Edit : Actually, startTaxiHotkey = is not needed. Thanks!

While possibly (depending on the rest of your code) not needed, startTaxiHotkey = on a line by itself is good practice, as that clears the value from the variable. The GuiControl,,startTaxiHotkey line updates the GUI, but does not actually clear the value.

If you have called Gui Submit or GuiControlGet, startTaxiHotkey, the variable will not be empty and GuiControl,,startTaxiHotkey will not clear it.

As for why your one-liner doesn't work, perhaps this will enlighten you:

Code: Select all

startTaxiHotkey = GuiControl,,startTaxiHotkey
MsgBox % startTaxiHotkey
