GuiCtrlSetTip don't work in a While-loop

6 posts in this topic

hello, please take a look at this example:

#include <GUIConstantsEx.au3>
Opt('MustDeclareVars', 1)
Example()
Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button")

    Opt("GUICoordMode", 2)
    $Button_2 = GUICtrlCreateButton("Button Test", 0, -1)
    GUICtrlSetTip($Button_2, "test")
    GUISetState()
    While 1
        sleep(20)
        ;GUICtrlSetTip($Button_2, "in-while")
        $msg = GUIGetMsg()
        Select
            Case $msg = $GUI_EVENT_CLOSE
                ExitLoop
        EndSelect
    WEnd
EndFunc

if you run this script untouched you will see the control-tip "test" works.

if you remove the comment in the while-loop, the control-tip should now be "in-while".

but this dont work. what is wrong here?

hessebou,

Your problem comes because you are resetting the ToolTip so often it never gets the chance to display. If you only change it now and again it works fine: :)

#include <GUIConstantsEx.au3>
Opt('MustDeclareVars', 1)
Example()
Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button")

    Opt("GUICoordMode", 2)
    $Button_2 = GUICtrlCreateButton("Button Test", 0, -1)
    GUICtrlSetTip($Button_2, "test")
    GUISetState()

    Local $iBegin = TimerInit()
    While 1
        If TimerDiff($iBegin) > 1000 Then
            GUICtrlSetTip($Button_2, "in-while " & @SEC)
            $iBegin = TimerInit()
        EndIf
        $msg = GUIGetMsg()
        Select
            Case $msg = $GUI_EVENT_CLOSE
                ExitLoop
        EndSelect
    WEnd
EndFunc

All clear? ;)

hey cool, i got it ;) now i can go on with some tests :)

setting the mouse-tip in a while-loop works fine without the timer-trick.

thank you

hello once again,

i coded a better solution: this works without timer and without flickering.

#include <GUIConstantsEx.au3>
Opt('MustDeclareVars', 1)
Example()
Func Example()
    Local $Button_1, $Button_2, $msg, $temptip = ""
    GUICreate("My GUI Button")
    Opt("GUICoordMode", 2)
    $Button_2 = GUICtrlCreateButton("Button Test", 0, -1)
    GUICtrlSetTip($Button_2, "test")
    GUISetState()
    While 1
        if Stringleft(ClipGet(), 7) = "http://" then
            if GUICtrlGetState($Button_2) = 144 or $temptip <> clipget() then
                $temptip = clipget()
                GUICtrlSetState ( $Button_2, $GUI_ENABLE )
                GUICtrlSetTip ( $Button_2, clipget())
            endif
        Else
            if GUICtrlGetState($Button_2) = 80 then
                GUICtrlSetState ( $Button_2, $GUI_DISABLE )
                GUICtrlSetTip ( $Button_2, "")
            endif
        endif
        $msg = GUIGetMsg()
        Select
            Case $msg = $GUI_EVENT_CLOSE
                ExitLoop
        EndSelect
    WEnd
EndFunc

what do you think about it?

Looks better compared to the old version.

Nice revise.

hessebou,

Nice coding to remove the flicker. ;)

That trick of testing the current value is one you will use again and again when you need to change the state or the text of a control in a tight loop. :)
