Tip Text for label not shown after using GUICtrlSetStyle() on that label

[MrCreatoR <mscreator@…>]

Hi,

First please check ​this thread, where the bug(?) is found.

It seems that when we using GUICtrlSetStyle on Label control (i checked only few more, such as button, checkbox, radio etc.), the tip that was/is set by GUICtrlSetTip() before/after using SetStyle function is not shown (destroyed?).

Reproducing example:

#include <GUIConstants.au3>
#include <StaticConstants.au3>

GUICreate("Test GUI", 250, 150)

$Label = GUICtrlCreateLabel("Test", 70, 45, 53, 15)

GUICtrlSetTip($Label, "My TIP")
GUICtrlSetStyle($Label, BitOr($GUI_SS_DEFAULT_LABEL, $SS_CENTER)) ;That's it, tip is not shown

GUISetState()

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

P.S

There is a workaround for this issue:

#include <GUIConstants.au3>
#include <Constants.au3>
#include <StaticConstants.au3>
#include <WinAPI.au3>

GUICreate("Test GUI", 250, 150)

$Label = GUICtrlCreateLabel("Test", 70, 45, 53, 15)
GUICtrlSetTip($Label, "My TIP")

$iStyle = _WinAPI_GetWindowLong(GUICtrlGetHandle($Label), $GWL_STYLE)
GUICtrlSetStyle($Label, BitOr($iStyle, $SS_CENTER))

GUISetState()

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

So my geuss that it's f problem in GUICtrlSetStyle()...
Any way, the function should not affect on the Tip creation for the control.

The behavior is as expected as GUICtrlSetStyle does not force any style just the one send. In tyhe soecific case $SS_NOTIFY is a forced style which is destroyed as it is not part of default style. you need to supply Forced style if wanted
