interesting accident

[ioa747]

I had an interesting accident. (I thing) 

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <Misc.au3>


_ColorsSelection()

Func _ColorsSelection()
    Local $hGUI = GUICreate("Colors Selection", 500, 500, -1, -1, -1)
    GUISetFont(10)
    GUICtrlCreateLabel("Red", 10, 10, 101, 17, 0x0002)
    GUICtrlCreateLabel("Green", 10, 140, 101, 17, 0x0002)

    Local $Button1 = GUICtrlCreateButton("", 120, 5, 50, 25, 0xFF0000) ; instead of 0x8000 I paste 0xFF0000
    GUICtrlSetBkColor(-1, 0xFF0000)
    Local $Button2 = GUICtrlCreateButton("", 120, 135, 50, 25, 0xFF0000) ; instead of 0x8000 I paste 0xFF0000
    GUICtrlSetBkColor(-1, 0x00FF00)
    GUISetState(@SW_SHOW)

    While 1
        $nMsg = GUIGetMsg()
        Switch $nMsg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $Button1
                ConsoleWrite("$Button1=" & $Button1 & @CRLF)
            Case $Button2
                ConsoleWrite("$Button2=" & $Button2 & @CRLF)
        EndSwitch
    WEnd
    GUIDelete($hGUI)
EndFunc   ;==>_ColorsSelection

Wow this is really kind of interesting. I don't even understand why it's doing that.

Maybe this explanation ?

1) Button when no style is indicated at creation (-1) , WS_TABSTOP will be forced (help file)

Button style becomes 0x50010000
WS_CHILD, WS_VISIBLE, WS_TABSTOP

[0x40000000, 'WS_CHILD']
[0x10000000, 'WS_VISIBLE']
[0x00010000, 'WS_TABSTOP']

2) Button created with 0xFF0000 style

Button style becomes 0x50FF0000
WS_CHILD, WS_VISIBLE, WS_OVERLAPPEDWINDOW, WS_VSCROLL, WS_HSCROLL

[0x40000000, 'WS_CHILD']
[0x10000000, 'WS_VISIBLE']
[0x00CF0000, 'WS_OVERLAPPEDWINDOW']
[0x00200000, 'WS_VSCROLL']
[0x00100000, 'WS_HSCROLL']

'WS_OVERLAPPEDWINDOW' means (WS_CAPTION | WS_SYSMENU | WS_SIZEBOX | WS_MINIMIZEBOX | WS_MAXIMIZEBOX)
