[A5] Display always on top? http://www.allegro.cc/forums/view/612307 Allegro.cc Forum Thread matthew@allegro.cc (Matthew Leverton) Sat, 30 Mar 2013 11:35:07 +0000

Is it possible to create a (fullscreen window) display so that it is always in front?

In a multi-monitor configuration like this:

{"name":"607332","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/5\/d\/5da3049d8c624dd915871ee08ae0bbb6.png","w":478,"h":269,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/5\/d\/5da3049d8c624dd915871ee08ae0bbb6"}607332

If I drag a window over, that window becomes the focused window and is brought to the front, on top of the allegro display:

{"name":"607333","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/d\/2\/d28c445acf967ef59e5cf2caf197cd9d.png","w":478,"h":269,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/d\/2\/d28c445acf967ef59e5cf2caf197cd9d"}607333

But I want the display to always be on top, like a powerpoint presentation window:

{"name":"607331","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/4\/8\/4894e3d65d89b11c104c3209d7dcabb1.png","w":478,"h":269,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/4\/8\/4894e3d65d89b11c104c3209d7dcabb1"}607331

Is there a setting for that somewhere?

I don't understand what you're trying to do...... hahahahahaha I'm kidding. You almost made a movie there man!.

Anyway, and what if you create a "real" fullscreen display in the second monitor? is not possible? I think that way nothing would be able to get on top.

The problem with that is when I just select a window in the primary display, the fullscreen is disappears (minimizes?)

Awww it's true. But I'm almost 100% sure that there is a way of doing it with the Windows handler (you know the HWND stuff) but I haven't done it before.

You'll probably need to get the Handler (al_get_win_window_handle(ALLEGRO_DISPLAY *display)) and then with some Windows specific code set it to be at the top all the time.

Maybe using something like SetWindowPos?

That's it!!! ;D ;D

AMCerasoli, you're a genjus!!!

I just added this code:

  HWND window_handle = al_get_win_window_handle(control_display->display);
  SetWindowPos(window_handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE + SWP_NOSIZE);

[edit] That makes me so haappyyyy!!! :D

Now set that same flag on the other window and see what happens.

Well I want to announce to everybody that Mark asked me to get marry with him. He sent me a PM because he was afraid that I could reject him.

The wedding is around 15 of April of this year in Tokyo. You're of course all invited.

Well..... OK :-*.

But we have to get a prenup. You ain't gettin' my Bitcoinzz! >:(

[edit]

On topic, I should note that when using ALLEGRO_FULLSCREEN_WINDOW, it does not have the expected behavior and a dragged window will appear above it. However, if the display is created with ALLEGRO_NOFRAME then it does work as expected.

Nit pick, but those mean don't honor the position and size parameters from the call, not what the comment says. :)
