Window Space Position & Size

[Nemcija 2]

Hi,

Does anyone know a way to get the position and size of the working space of a window, independent of the style of the window.

I've got a screenshot here, the area i'm talking about i've marked red.

Thank you for your ideas

You want the client rectangle. WinApi.au3 has 3 functions that you may want:

_WinAPI_GetClientRect

_WinAPI_GetClientHeight

_WinAPI_GetClientWidth

example: (taken from the helpfile entry for "_WinAPI_GetClientRect")

Opt('MustDeclareVars', 1)

#include <WinAPI.au3>

_Main()

Func _Main()
    Local $hwnd, $tRect
    $hwnd = GUICreate("test")
    $tRect = _WinAPI_GetClientRect($hwnd)
    MsgBox(4096, "Rect", _
            "Left..: " & DllStructGetData($tRect, "Left") & @LF & _
            "Right.: " & DllStructGetData($tRect, "Right") & @LF & _
            "Top...: " & DllStructGetData($tRect, "Top") & @LF & _
            "Bottom: " & DllStructGetData($tRect, "Bottom"))
EndFunc   ;==>_Main

This doesn't solve the problem completely, maybe i've forgotten to tell you that I need the absolute position on screen, not relative to the window.

This returns

Left: 0

Right: 400

Top: 0

Bottom: 400

So its very similar to WinGetClientSize ( )

But for example the window is in the middle of my screen it should be

Left: 0 + x

Right: 400 + x

Top: 0 + y

Bottom: 400 + y

I can't take the information vom WinGetPos ( ) because this includes the border and the titlebar.

Try _WinAPI_ClientToScreen()

Okay, I've got a solution for myself. Don't know whether its always working correctly, or maybe there is an easier way ...

But it does what I need

expandcollapse popup

#include <WinAPI.au3>

$hwnd = GUICreate("test",100,150,5,200)
$rect = _WinAPI_GetClientScreenRect($hwnd)
If IsArray($rect) Then
    MsgBox(0, "_WinAPI_GetClientScreenRect Example", _
        "Left: " & $rect[0] & @CRLF & _
        "Right: " & $rect[1] & @CRLF & _
        "Top: " & $rect[2] & @CRLF & _
        "Bottom: " & $rect[3])
Else
    MsgBox(0,"Failed","Failed")
EndIf

    $aiReturnValue[3] = $aiReturnValue[2] + DllStructGetData($tLocalClientRect, "Bottom")
    Return $aiReturnValue
EndFunc

At least it just combines two functions ^^

Maybe its usefull for someone else ...

Sorry if it is not named/documented correctly, I'm not familar with this things for autoit ...

Thank you for your help!
