[Solved] Destructors called on object creation?

1 post in this topic

#1 ·  Posted (edited)

I am trying a useless script just for giggles wherein the GUI and all of it's controls are self contained objects. However, when I first run the script the destructors for all of the controls are called once at startup and again at shutdown. I know that the destructors are supposed to be called once right? Any help will be appreciated.

There are two main classes: objCtrl and objGUI. All controls inherit from objCtrl.

The destructor for objGUI seems to work as intended.

Update: I think I got it. I was calling _AutoItObject_Create() in the objLabel and objButton functions. I removed those and now it works right!

Here is the script:

Example.au3

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseX64=n
#AutoIt3Wrapper_Au3Check_Stop_OnWarning=y
#AutoIt3Wrapper_Au3Check_Parameters=-w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -d
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

#include <AutoItObject.au3>

#include <objCtrl.au3>
#include <objLabel.au3>
#include <objButton.au3>
#include <objGUI.au3>

_AutoItObject_Startup()

Global $GUI = objGUI()
$GUI.Create( "Experiment" , 400 , 300 )
$GUI.OnEvent( -3 , "GUI_Exit" )

Global $label = objLabel( "Hey you!" , 20 , 30 , 100 , 30 )

Global $button = objButton( "Click Me!" , 10 , 100 , 100 , 100 )
$button.SetTip( "What are you staring at?" , "HEY" , 3 )
$button.OnEvent( "Hello" )

While 1
    Sleep( 100 )
WEnd

Func Hello()
    $label.SetPos( 0 , 0 )
