Center text for GUICreate

6 posts in this topic

Hello,

Is there a way to center text for GUICreate?

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Local $MyGUI = GUICreate("GUI Test", 400, 100, -1, -1, $WS_BORDER)
GUISetState(@SW_SHOW)


Do
    Local $msg = GUIGetMsg()
Until $msg = $GUI_EVENT_CLOSE

I have tried many ways but the text 'GUI Test' is always on the left.

What I don't want to do is whitespace before the text.

Any help would be appreciated.

Even if there were an easy way to center the text, it would still have whitespace before the title text. But, there's no easy way that I'm aware of to do it.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

NewPlaza,

If you use my StringSize UDF you can do it this way: :)

#include <GUIConstantsEx.au3>
#include <StringSize.au3>
#include <WinAPI.au3>

$iGUI_Width = 500

$sGUI_Title = "Centred Title"

$hGUI = GUICreate("Test", $iGUI_Width, 500)

GUISetState()

$iButton_Width = _WinAPI_GetSystemMetrics(30) ; SM_CXSIZE
$iBorder_Width = _WinAPI_GetSystemMetrics(7) ; SM_CXFIXEDFRAME
$iTitle_Width = $iGUI_Width - (3 * $iButton_Width) - (8 * $iBorder_Width)

While 1

    ; Add white space to each end of title
    $sGUI_Title = " " & $sGUI_Title & " "
    ; Get width of title
    $aRet = _StringSize($sGUI_Title)
    If $aRet[2] > $iTitle_Width Then
        ; If now too large, remove last added spaces
        $sGUI_Title = StringTrimLeft(StringTrimRight($sGUI_Title, 1), 1)
        ExitLoop
    EndIf

WEnd
; Set title
WinSetTitle($hGUI, "", $sGUI_Title)


While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd
Any use? :huh:

I modified an old example of mine. You can play around with it.

Edit: I just saw, that on Win7 the coords for the RECT don't match. I will need time to work the right way on WinXP AND above.

I decided to play around with some code to center text and came up with this.

#include <WinAPI.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Local $pGUI = GUICreate("", -1, -1, -1, -1, $WS_BORDER)
GUISetState()

Local $pSize = WinGetPos($pGUI)
Local $cGUI = GUICreate("", $pSize[2], $pSize[3], $pSize[0], $pSize[1], $WS_POPUP, $WS_EX_LAYERED, $pGUI)

GUICtrlCreateLabel("THE TEXT IS CENTERED", 0, 0, $pSize[2], $pSize[3], $SS_CENTER)
GUICtrlSetFont(-1, 10, 800)
GUISetBkColor(0xABCDEF)
GUICtrlCreateLabel("Some kind of text or whatever", 10, 30, 70)
_WinAPI_SetLayeredWindowAttributes($cGUI, 0xABCDEF, 255)
GUISetState()

While 1
    GUIGetMsg()
WEnd

I would like to know if there might be any issues I'm not aware of and for any WinXP/Vista users, I would like to know if it will even work.

Thanks for viewing.
