_WinAPI_DrawText Problem : Text can be clicked through it

[komalo]

i am having a problem with _WinAPI_DrawText when using it

with the DC of a Layered Window _WinAPI_UpdateLayeredWindow

with it can be clicked through it even if i changed the Text Color with

_WinAPI_SetTextColor

here's an example ( this is not my code it just shows my probelm )

#NoTrayIcon
#include <GDIPlus.au3>
#include <TransWinAPI.au3>
#include <SendMessage.au3>
#include <FontConstants.au3>
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>

Global Const $DT_END_ELLIPSIS = 32768
$hWnd = GUICreate("",-1,-1,-1,-1,-1,$WS_EX_LAYERED)
_WinAPI_SetLayeredWindowAttributes($hWnd, 0)
GUISetState()
$hDC = _WinAPI_GetDC($hWnd)
$tRect = DllStructCreate($tagRECT)
DllStructSetData($tRect, 1, 43)
DllStructSetData($tRect, 2, 20)
DllStructSetData($tRect, 3, 125)
DllStructSetData($tRect, 4, 100)
_WinAPI_DrawText($hDC,"aaaa", $tRect, $DT_END_ELLIPSIS) ;try to move the window
Do
Until GUIGetMsg() = -3

If you set the text colour to be the transparent colour then you will be able to see the window behind your window and if you click on a transparent area you will be clicking on the window behind. If you don't want that to happen you would need to have some way to make the text not completely transparent. What i sthe effect you want to achieve?

[komalo]

i am not trying to achieve any effect , it just

happened while using it with a Layered Gui

all i want that make the text solid not transperent

[ProgAndy]

Why do you use a layered GUI, when you don't need it? To have solid black text, set the transparent color for the layered window to another color than black.

[komalo]

i am using a layered GUI to be able to use _WinAPI_UpdateLayeredWindow

so i can't use _WinAPI_SetLayeredWindowAttributes to set the transperent

color to another color than black , i tried to set the text color to another color

but it just stays transparent .

Does it work, if you use WinSetTrans instead of _WinAPI_SetLayeredWindowAttributes

or using

_WinAPI_SetLayeredWindowAttributes($hWnd,0,255,0x2)?

[komalo]

nope

Hi. Anyone can tell me how could i move the drawed text with _WinApi_DrawText like WinMove? sorry for my bad english

Here is an example showing solid coloured text, and moving the text with the arrow keys.
