setting program to display always on top of other windows without having the focus?
#1
Is there a command or way to set your program to stay on top of other windows (and keep running), even if it doesn't have the focus? 
If there is, then I want to make line 31 enable always on top in the programs below, and line 34 disable always on top. 
Is this possible? Any info appreciated!

Interesting - I'll give this a try when back at the PC. Thanks!

I wonder if it's possible to do this on Mac and Linux? If so, maybe we could add a $WINDOW_ONTOP:ON or something?

How difficult is it to add new things to the QB64PE sourcecode?

Has anyone ever documented that, or the steps required in a tutorial? We might be able to cast a wider net of PRs if we did.

Fantastic!

Now once the program window is set to always be in the foreground, how would you change it back to a normal window? 

I tried modifying my programs so 
a window stays on top (HWND_TOPMOST) when the user presses the "a" key, 
and goes back to normal (HWND_NOTOPMOST) when they press "b", 
but it doesn't seem to be working...

but it doesn't seem to be working...

But your programs are fine.
If you press key B the window is no longer in the foreground and with A it is in the front again.
All you have to do is click on it with the mouse to give the program focus again, and then press the corresponding keys.
And the second program should not be in the same place as the first.
The function brings the window to the foreground, but does not hold the focus.

@madscijr It works as expected on my PC. Smile

I think the problem is you're clicking "b" while the program doesn't have focus, so it's not going to read that input and change modes on you.

Run the second program as you have it written, and click "a" to make it stay on top. Then click anywhere else you want and watch as that window remains on top of everything else.

Now open notepad, or your browser, or whatever, and hit "b".... Notice how you just typed a "b" on that newly opened app? It's where your input is being directed to.

Click back on the "always on top" program and hit "b". Maybe hit it twice for good measure to make certain that it catches that input. Watch the status change to "BACKGROUND".

At least, that's how it's working for me on Win 11. Smile

Thanks for your reply - I'm away from my PC now but what I was seeing (in Windows 11) 
was that alt-tabbing to the program not set to "top" (or even clicking it), it moved to the top. I would expect the one not on top to stay underneath. I'll give it a look when I'm back at the computer - thanks again.

Thank you both for your replies. 
I see what was happening - both were initializing as "top" so whichever one got the focus went to top.

I fixed that and now it's working, just one problem now, which is that when you press "a" or "b" and the program changes the "always on top" state, the window moves. 

I see that lines 81 and 87 are calling SetWindowPos with X& and Y& hardcoded to 200:

Code: (Select All)
Function SetWindowPos& (ByVal hWnd%&, Byval hWndInsertAfter%&, Byval X&, Byval Y&, Byval cx&, Byval cy&, Byval uFlags~&)
...
If SetWindowPos(hWndThis, HWND_TOPMOST, 200, 200, 0, 0, SWP_NOSIZE Or SWP_NOACTIVATE) = 0 Then
Is there a way to get the current window x, y position to pass to SetWindowPos so the window stays at its current position? 

Thanks again!
