Ternary line for GUI loop?

[littlebigman]

Hello,

Just to keep the GUI open after doing stuff, I need to rerun a basic GUI loop.

As an alternative to a Do/Until, I tried a ternary one-liner, but AutoIt doesn't like the syntax:

;So the app doesn't close after the for loop
;~ Do
;~     Sleep(10)
;~ Until GUIGetMsg() = $GUI_EVENT_CLOSE
;BAD (GUIGetMsg() = $GUI_EVENT_CLOSE) ? (Exit) : (Sleep(10))
;BAD GUIGetMsg() = $GUI_EVENT_CLOSE ? Exit : Sleep(10)

Is that syntax just impossible?

Thank you.

Not impossible, but for starters: Why do you think that a one line If or  Ternary can replace a loop?
You only test one time this way!

Just because I was curious to see if it could be further shortened.

What's the purpose? You still need the loop to keep you app running. This reminds me of this.

Makes sense. So it's not a good idea

While GuiGetMsg() <> -3 And Sleep(10)
WEnd

Hmm, according to "Oscar" on the german autoit forum, a guy worth listening to,  the sleep isnt even necesary when using GuiGetMsg()...

GUIGetMsg automatically creates sleeps (without mouse movement/keystrokes) to reduce the load on the processor.

So...

While GuiGetMsg()<>-3
WEnd

...should be enough.

Guess Oscar read the helpfile as it is clearly defined how a msg loop works and no sleep() is needed : https://www.autoitscript.com/autoit3/docs/guiref/GUIRef_MessageLoopMode.htm

It is actually discouraged to add any sleep(). 😉

Just to prevent the GUI being unresponsive but this won't happen if you sleep just a few ms. I think for most people it's a habit to use the sleep in main loop. I know for years that GUIGetMsg() automatically idles the CPU and yet I still use that sleep most of the time.

yes, but you are aware of how many people actually reads the helpfile.

Hardly anybody actually reads the whole page ever.... Only a few open it.
