Which is "better" in a GUI-loop?

Recommended Posts

faldo

If i remember corectly, the select-statement came later, chronologicly so i've allways used while...If in all my GUI's.

Which is the prefered alternative out there, are there any drawbacks with either of the following GUI's?

Either:

#include <GUIConstantsEx.au3>

GUICreate("Title goes here")
GUISetState()

While 1
$msg = GUIGetMsg()
Select

Case $msg = $GUI_EVENT_CLOSE
ExitLoop

EndSelect
WEnd
GUIDelete()

Or:

#include <GUIConstantsEx.au3>

GUICreate("Title goes here")
GUISetState()

While 1
$msg = GUIGetMsg()

If $msg = $GUI_EVENT_CLOSE Then ExitLoop

WEnd
GUIDelete()

Or with a switch :

#include <GUIConstantsEx.au3>

GUICreate("Title goes here")
GUISetState(@SW_SHOW)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch

    Sleep(10)
WEnd
GUIDelete()

oh, i didn't know the switch, nifty.

Are there any difference in CPU/memory-load, timers, idle attributes etc. if you compare these three loops?

No, except that the If statement is "slower" than a select/switch.

On a little snippet like this, there is no matter to talk about efficiency.

Br, FireFox.

I also find passing the hWnd returned by GUICreate to be best practice as well. It saves a lot of headache with the relying on the last created GUI.

#include <GUIConstantsEx.au3>

Example()

Func Example()
    Local Const $hGUI = GUICreate('Title goes here') ; This is a constant variable as why would you want $hGUI to be changed in this example?
    GUISetState(@SW_SHOW, $hGUI)

    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop
        EndSwitch
    WEnd
    GUIDelete($hGUI)
EndFunc   ;==>Example
