How to make given color transparent on GUI

[E1M1]

How to make given color transparent? Seethe right upper notepad on screen shot. you can see that notepad itself is not transparent but only white color of it is transparent.

Do you want your GUI transparent as in the image on the right side or do you want to code a program which make a given color transparent from any GUI?

code which makes any gui transparent would also work on my own gui. _WinAPI_SetLayeredWindowAttributes example does that, but it didn't work on notepad, I guess i have to make it layerew window somehow.

E1M1,

I would make a GUI with a transparent client area like this:

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

$hGUI = GUICreate("Test", 500, 500, -1, -1, -1, $WS_EX_LAYERED)
GUISetBkColor(0xABCDEF)

GUICtrlCreateLabel("I am a GUI with a transparent client area", 10, 10)

_WinAPI_SetLayeredWindowAttributes($hGUI, 0xABCDEF, 250)

GUISetState()

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

Is that what you wanted?

Try this:

#include <GuiEdit.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>

Opt('MustDeclareVars', 1)

Local $hGUI, $hEdit, $hChild, $hLabel

; Create GUI
$hGUI = GUICreate("", 400, 300, -1, -1)
$hChild = GUICreate("Notepad", 400, 300, -1, -1, Default, BitOR($WS_EX_MDICHILD, $WS_EX_LAYERED, $WS_EX_TOPMOST), $hGUI)
$hEdit = _GUICtrlEdit_Create($hChild, "", 2, 2, 394, 268, -1)
GUICtrlSetBkColor ($hEdit, 0xFFFFFF)
_WinAPI_SetLayeredWindowAttributes($hChild, 0xFFFFFF, 255)
$hLabel = GUICtrlCreateLabel("", 0, 0, 400, 300, -1, $GUI_WS_EX_PARENTDRAG)
GUISetState()

_GUICtrlEdit_SetText($hEdit, "This is a test" & @CRLF & "Another Lne")

; Loop until user exits
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE
GUIDelete()

It might work only on Vista+ os!

Further I'm not so familiar with GUIs and I don't know how to move and get focus on the GUI. If I will find it I will update the code.

E1M1,

That is a whole different problem. Search for "+click + through +transaparent" and you will find lots of posts about it - but they all seem to rely on the $WS_EX_TRANPARENT style which affects all parts of the GUI and not just the client area.

UEZ yours makes mouseclicks go trough close button. I have seen C# gui made so that mouse clicks doesnt fall trough GUI items like bottons and such..
