How do I use DrawThemeTextEx to get glowing text on aero glass?

Vadersapien · November 11, 2009

Got the text positioned...but...say my _DrawTime() function is like this:

Func _DrawTime()
    Local $hDC = _WinAPI_GetDC($hGUI)
    Local $tClientRect = _WinAPI_GetClientRect($hGUI)
    Local $tST = _Date_Time_GetLocalTime()
    Local $sText = _Date_Time_SystemTimeToTimeStr($tST)
    Local $hFont = _WinAPI_CreateFont(15, 6, 0, 0, 400, False, False, False, $DEFAULT_CHARSET, _
        $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, 'Segoe UI') ; Edit as necessary.
    
    DllStructSetData($tClientRect, "Top", 76)
    
    _DrawGlowingText($hDC, $sText, $tClientRect, 10, $hFont, 0x000000) ; BGR, implementing RGB is easy.
    
    _WinAPI_DeleteObject($hFont)
    _WinAPI_ReleaseDC($hGUI, $hDC)
EndFunc

Positioning the text with this code:

DllStructSetData($tClientRect, "Top", 76)

It works, but leaves a big white rectangle at the top...any idea why?

Make sure you handle $WM_ERASEBKGND and fill the client area, the DWM seeks for pixels with the color 0x000000 (100% transparent black) in your GUI to apply the blur effect:

Func _WM_ERASEBKGND($hWnd, $iMsg, $iwParam, $ilParam)
    Local $hDC = $iwParam
    Local $tClientRect = _WinAPI_GetClientRect($hWnd)
    Local $hBrush = _WinAPI_GetStockObject($BLACK_BRUSH)
    
    _WinAPI_FillRect($hDC, DllStructGetPtr($tClientRect), $hBrush)

    Return 1
EndFunc

This code is from this article. This guy tried numerous things and the best he came up with is this one which requires much more code (for every control) but not as much dealing with owner drawn controls:

I guess that Vista doesn't make it easy with the old GDI drawing controls. ::

Thanks alot for your answer

The first Method is realy complicated, and flickrs a little bit (sometimes it tooks some seconds until the text is black again).

The second Method is nice, but its hard to read anyway.

I founded out, that we dont need WM_CTLCOLOREDIT. It's very easy:

Global $Edit = GUICtrlCreateInput("Hello World",20,10,260,25)
GUICtrlSetColor(-1,0xFFFFFF)
GUICtrlSetBkColor(-1,0)
GUICtrlSetFont(-1, 15, 500)

Same effect but much less code.

So. Does anybody now perhaps another method to draw black (or dark) Text in AutoIt Controls (like GuiCtrlCreateInput,Button,...)

I guess that Vista doesn't make it easy with the old GDI drawing controls. ::

I guess you're right ;-) Windows allways try to make it easy for devs. But why the heck not with Aero developing? ;P

Greetings,

A quick question...how would I make the text positioned from the top and not the center?

Yashied · May 24, 2010

Hey there,

Is there also a posibility to draw e.g. Inputs (GuiCtrlCreateInput) on Aero? So that black is not transparency? (I think we just have to set the Alpha Channel to 255 (0xFF000000).)
Any Ideas?

You can do the following trick.

#Include <WinAPIEx.au3>
#Include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

Global $hForm, $AlphaKey = 0xABABAB

$hForm = GUICreate('MyGUI', 400, 400, -1, -1, -1, $WS_EX_LAYERED)
GUISetBkColor($AlphaKey)
GUICtrlCreateInput('Simple Text', 20, 20, 360, 19)
GUICtrlCreateEdit('', 20, 47, 360, 200)
GUICtrlCreateButton('OK', 165, 370, 70, 23)

_WinAPI_SetLayeredWindowAttributes($hForm, $AlphaKey, 0, $LWA_COLORKEY)
_WinAPI_DwmExtendFrameIntoClientArea($hForm)

GUISetState()

Do
Until GUIGetMsg() = -3

A more complex example.

#Include <GUIConstantsEx.au3>
#Include <WinAPIEx.au3>
#Include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)
Opt('WinWaitDelay', 0)

Global Const $WM_NCXBUTTONDOWN = 0x00AB

Global $hForm, $Area, $hDll, $pDll, $hHook, $AlphaKey = 0xABABAB

OnAutoItExitRegister('OnAutoItExit')

$hForm = GUICreate('MyGUI', 400, 400, -1, -1, -1, $WS_EX_LAYERED)
GUISetBkColor($AlphaKey)
$Area = GUICtrlCreateLabel('', 0, 0, 400, 400)
GUICtrlSetBkColor(-1, $AlphaKey)
GUICtrlSetState(-1, $GUI_DISABLE)
GUICtrlCreateInput('Simple Text', 20, 20, 360, 19)
GUICtrlCreateEdit('', 20, 47, 360, 200)
GUICtrlCreateButton('OK', 165, 370, 70, 23)

_WinAPI_SetLayeredWindowAttributes($hForm, $AlphaKey, 0, $LWA_COLORKEY)
_WinAPI_DwmExtendFrameIntoClientArea($hForm)

$hDll = DllCallbackRegister('_MouseHook', 'ptr', 'int;wparam;lparam')
$pDll = DllCallbackGetPtr($hDll)
$hHook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, $pDll, 0)

GUISetState()

Do
Until GUIGetMsg() = -3

Func _MouseHook($iCode, $wParam, $lParam)
    If $iCode > -1 Then
        Switch $wParam
            Case $WM_LBUTTONDOWN, $WM_MBUTTONDOWN, $WM_RBUTTONDOWN, $WM_XBUTTONDOWN, $WM_NCXBUTTONDOWN

                Local $Data = GUIGetCursorInfo($hForm)

                If (IsArray($Data)) And ($Data[4] = $Area) Then
                    If Not BitAND(WinGetState($hForm), 8) Then
                        WinActivate($hForm)
                    EndIf
                    Return -1
                EndIf
        EndSwitch
    EndIf
    Return _WinAPI_CallNextHookEx($hHook, $iCode, $wParam, $lParam)
EndFunc   ;==>_MouseHook

Func OnAutoItExit()
    _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hDll)
EndFunc   ;==>OnAutoItExit

Hmm...your example doesn't work for me. I'm on Windows Vista (maybe the API changed between Vista and 7?) See attached.

MilesAhead · August 18, 2010

You can do the following trick.

Thanks for this Yashied. I used your code and example to provide an alternative Gui option for 7 users.

On Vista Glass, or if the option is disabled on 7, the Gui looks like this:

but if the 7 user enabled the .ini option it uses your code:

http://www.favessoft.com/SelectorTrans.jpg

edit: I kludged it to make the text easier to read. A little cheesy but maybe I'll find a better way later.

How do I use DrawThemeTextEx to get glowing text on aero glass?
