$GUI_ONTOP hides the control when already on top

[Nine]

Setting the button to $GUI_ONTOP makes it disappear :

#include <GUIConstants.au3>

Local $hGUI = GUICreate("Example", 300, 200, -1, -1, BitOR($WS_POPUP, $WS_BORDER))
GUISetBkColor(0xC0C0C0)

Local $idLabel = GUICtrlCreateLabel("", 0, 0, 300, 200, Default, $GUI_WS_EX_PARENTDRAG)

Local $idClose = GUICtrlCreateButton("Close", 210, 170, 85, 25)
GUICtrlSetState(-1, $GUI_ONTOP)

GUISetState()

While True
  Switch GUIGetMsg()
    Case $GUI_EVENT_CLOSE, $idClose
      ExitLoop
    Case $idLabel
      ConsoleWrite("Label" & @CRLF)
  EndSwitch
WEnd

Giving focus ($GUI_FOCUS) to the button is a workaround, but when GUI has hundred controls it is hardly viable.

Adding a $WS_CLIPSIBLINGS style when creating the label seems to solve the issue in the script presented above, where controls overlap. Is this solution ok ?

Local $idLabel = GUICtrlCreateLabel("", 0, 0, 300, 200, $WS_CLIPSIBLINGS, $GUI_WS_EX_PARENTDRAG)

Nice catch @pixelsearch
I will add to the doc pointing to this article

I will not change the default as this article point out a little perf draw back

$GUI_ONTOP is meant for GUI's and not for GUI Controls. Isn't it?

Sorry. Never mind. Looked it up.

kurtykurtyboy indicates another working solution : adding $WS_EX_COMPOSITED as GUI extended style, which does the job in Nine's script above.

It's good to know we got 2 workable solutions when controls overlap : $WS_CLIPSIBLINGS as style for the background control, or $WS_EX_COMPOSITED as GUI extended style.
