What is the difference between MessageLoop and OnEvent

[winkot]

What is the difference between MessageLoop and OnEvent ? I made two scripts:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#Region (=== GUI generated by GuiBuilderPlus 1.3.0 ===)
Global $hGUI = GUICreate("MyGUI", 400, 350, 771, 302)

Global $Button_1 = GUICtrlCreateButton("Кнопка 1", 120, 160, 161, 41)
GUICtrlSetFont(-1, 15)
Global $Button_2 = GUICtrlCreateButton("Кнопка 2", 120, 239, 161, 41)
GUICtrlSetFont(-1, 15)
#EndRegion (=== GUI generated by GuiBuilderPlus 1.3.0 ===)


GUISetState(@SW_SHOWNORMAL)

While 1
    Switch GUIGetMsg()

        Case $Button_1
            Sleep(5000)
            Beep(500, 200)
        Case $Button_2
            Beep(1000, 100)
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

And

expandcollapse popup

Opt("GUIOnEventMode", 1)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#Region (=== GUI generated by GuiBuilderPlus 1.3.0 ===)
Global $hGUI = GUICreate("MyGUI", 400, 350, 771, 302)
Global $Button_1 = GUICtrlCreateButton("Кнопка 1", 120, 160, 161, 41)
GUICtrlSetFont(-1, 15)
Global $Button_2 = GUICtrlCreateButton("Кнопка 2", 120, 239, 161, 41)
GUICtrlSetFont(-1, 15)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
GUICtrlSetOnEvent($Button_1, "Func1")
GUICtrlSetOnEvent($Button_2, "Func2")


#EndRegion (=== GUI generated by GuiBuilderPlus 1.3.0 ===)

    GUISetState(@SW_SHOWNORMAL)

While 1
  Sleep(100)
WEnd

Func Func1()
   Sleep(5000)
  Beep(500,200)
EndFunc

Func Func2()
  Beep(1000,100)
EndFunc


Func _Exit()
    GUIDelete()
    Exit
EndFunc   ;==>_Exit

Both behave the same. When I press Button 1, until its function is completed, the function of Button 2 does not work. So how do these two modes differ?

winkot,

I suggest you read the <GUI Reference> section of the Help file which goes into some detail as to the differences between the 2 modes. Basically IMO it is down to personal choice.

You mention that you cannot interrupt a running function in either mode. This is not strictly the case - can I point you to the "Interrupting a running function" tutorial in the Wiki where you will learn just how you can do this.

Look in my signature for "fork". It may just do what you want to have.

"fork"

Where I can find it?

Look in my signature, search for "fork". But never mind. I don't think you'll be able to use it.

I can not find answer in my question at the Help file. In my opinion  the global difference is that OnEvent can interrupt process. And it all.

And you are wrong. I suggest you go and read both of the links I posted above. The first points to the Help file and explains the fundamental difference between the 2 modes , while the second points to the Wiki tutorial which explains how you can interrupt functions in either mode.
