Order of Tabs Changes depending on where GuiSetState is

[kylomas]

When I run the following the tabs are displayed in the order that I create them...

#include <TabConstants.au3>
#include <GUIConstantsEx.au3>

Local $gui010 = GUICreate('', 500, 400)
GUICtrlCreateTab(0, 20, 500, 360, BitOR($TCS_MULTILINE, $TCS_FIXEDWIDTH))
GUICtrlSetFont(-1, 10, 600, -1, 'courier new')

GUISetState()

For $1 = 0 To 25
    GUICtrlCreateTabItem(Chr($1 + 65))
    GUICtrlCreateTabItem('')
Next

While 1
    Switch GUIGetMsg()
        Case $gui_event_close
            Exit
    EndSwitch
WEnd

When I move the GuiSetState() to after tabitem creation the order changes...

#include <TabConstants.au3>
#include <GUIConstantsEx.au3>

Local $gui010 = GUICreate('', 500, 400)
GUICtrlCreateTab(0, 20, 500, 360, BitOR($TCS_MULTILINE, $TCS_FIXEDWIDTH))
GUICtrlSetFont(-1, 10, 600, -1, 'courier new')

For $1 = 0 To 25
    GUICtrlCreateTabItem(Chr($1 + 65))
    GUICtrlCreateTabItem('')
Next

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $gui_event_close
            Exit
    EndSwitch
WEnd

It appears that the first tab created is made visible.  Is this expected behavior or another brain cramp on my part?

kylomas,

This will get the tabs displayed in the correct order with GUISetState after the creation:

#include <TabConstants.au3>
#include <GUIConstantsEx.au3>

Local $gui010 = GUICreate('', 500, 400)
GUICtrlCreateTab(0, 20, 500, 360, BitOR($TCS_MULTILINE, $TCS_FIXEDWIDTH))
GUICtrlSetFont(-1, 10, 600, -1, 'courier new')

For $1 = 0 To 25
    GUICtrlCreateTabItem(Chr($1 + 65))
Next
GUICtrlSetState(-1, $GUI_SHOW) ; Force focus to final tab
GUICtrlCreateTabItem('')       ; Only needed the once

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $gui_event_close
            Exit
    EndSwitch
WEnd

Note that the order does not survive the first tab selection.

M23 - Yes, thanks.  Wondering about the behavior though.  Is this expected or am I missing something.  It also begs the question, "why does this happen?".

edit:  While we're at it...Is there any more detail on GuiCtrlCreateTab('') for closing the tab group.  I played with it briefly and it did not seem to matter.

Never mind, not enough research.  It seems this applies to control behavior specifically.
