[the question of how an application can force some part of itself as the top level window is a FAQ]
Could someone please write something here about the topic?

The API function needed is (see also [L1 ]):
SetWindowPos(HWND hWnd, // handle to window
HWND hWndAfter, // placement order handle
int x, int y, // position (horizontal, vertical)
int cx, int cy, // size (width, height)
UINT uFlags) // positioning flagsThe placement order handle can be either another HWND or once of the following constants:
The Flags can be one of a number but for this page probably SWP_NOMOVE (2) and SWP_NOSIZE (1) are likely the most useful. So:
SetWindowPos([winfo id .], HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE)
which turns out to be the code used by XRaiseWindow in win/tkWinWindow.c
Melissa Schrumpf recommends the GPLed WinCtl [L2 ] utility, which makes it possible to write
exec WinCtlW.exe -id [wm frame .] topmost &
(or might there be more punctuation in the vicinity of the id?).
I found the original topmost package made by John Rosauer in 12.1997. It works only with tcl/tk v.8.0.
The URL is: ftp://ftp.dcade.de/pub/ml/tcl/projects/topmost10/topmost10.zip [L3 ]
So I created a Visual Studio project to create an uptodate stubs enabled package usable from tcl/tk v.8.1 and higher.
The first call of Tk_MainWindow(ip) (topmost.cpp, line 277) with the pointer to the current interpreter inside the topmost command causes a access violation.
I tried with the tcl versions 8.1(.1) and 8.3.4 (tclstubs8(1|3).lib, tkstubs8(1|3).lib with the corresponding include files tcl.h, tk.h and tkWin.h) on Windows 2000/SP2.
Even the try of a call of Tk_GetNumMainWindows() caused a access violation.
The URL to the sources is: ftp://ftp.dcade.de/pub/ml/tcl/projects/topmost20a/topmost20a.src.zip [L4 ] (< 3 kB)
The URL to the VisualStudio project is (tcl/tk 8.3.4 runtime environment included): ftp://ftp.dcade.de/pub/ml/tcl/projects/topmost20a/topmost20a.vcppproj.zip [L5 ] (4.861 kB)
Has anybody a hint or a suggestion?
Thanks
