MDI childs doesn't adjust to parent windows client rect

[monoceres]

When using the $WS_EX_MDICHILD style the MDI child doesn't adjust properly to the parent window's client rect (as specified b the documentation).

The problem is illustrated in the sample below:

#include <GuiConstantsEx.au3>
#include <windowsconstants.au3>

$MainhWnd = GUICreate("Welcome", 400, 300)
GUISetBkColor(0)
GUISetState()

$childhwnd = GUICreate("", 400, 300, 0, 0, $WS_POPUP+$WS_CHILD, $WS_EX_TOPMOST + $WS_EX_MDICHILD, $MainhWnd)
GUISetBkColor(0xFF0000)
GUISetState()
WinSetTrans($childhwnd, "", 128)


Do
Until GUIGetMsg()=-3

Also, it seems there are no reliable way to move a MDI child within the parent window since WinMove() takes absolute screen coordinates.

I am afraid to do a script breaking in making the code according to the doc, which is the most logical as title bar height can vary according to the theme
Perhaps I should just change the doc to say relative to windows area instead of client area.

So how should one handle the situation? Using the child mdi style seems very unreliable to me now since I have no idea where the child might appear on the target users machine.

I guess the GetSystemMetrics() api can solve the issue, but this is tedious todo with different styles and such, maybe something that could be solved internally?

So you vote for a small script breaking.

Replying to Jpm:

Yes.

So I will do it
if menu is used in the parent windows it will be outside the client area
