That did the trick!

Try explicitly preventing switching the compositing off by setting this
window property (with value 0) to your application window:
static void set_compositing (Display *display, Window xwindow)
{
Atom atom;
int zero = 0;
atom = XInternAtom (display, "_HILDON_NON_COMPOSITED_WINDOW", False);
XChangeProperty (display,
xwindow,
atom,
XA_INTEGER, 32, PropModeReplace,
(unsigned char *) &zero, 1);
}

I've tried your example code and I get the exact same behavior. No transparency. I've looked for differences between your code and my code, tried some things, but couldn't find anything that did affect the result. I'm quite sure that it is a problem with the compositor, because I can see the transparency if I start your example and go to fullsceen. Then quickly open and close the virtual keyboard. After that the button is transparent for a couple of seconds. Probably the virtual keyboard enables the compositor. >From what I know the compositor should automatically get started "when it is needed". But unfortunately I have no idea how that is determined. Maybe someone with more knowledge of Maemo internals could comment on that. I've never used the full screen button outside of Conboy and only developed it in this context. Still, I could find Maepad where the button is also working (not sure if there are more working examples). I really hope we can find out why it is working in some applications and why not in others. After that I'll happily fix this bug in HeFullscreenButton. Unfortunately I'm currently out of ideas. If you (or anyone else) have ideas/input/anything, please let me know. Sorry that I can't be more helpful right now. Cheers, Conny P.S.

For example, the "banner" window, or a Hildon Animation Actor. Since you can easily create the latter (hildon_animation_actor_*), I would use that to keep the window manager from switching. On the other side, you should check if you really need to keep compositing enabled if you're not using any window needing it. AFAIK, the fullscreen hildon-extras is not actually using composition but some other strategy.

Re: [Fremantle] Compositing is disabled in fullscreen
I do not think the compositor effects placement and transparency of buttons themselves that sounds more like a theming issue?

I still had no luck solving this problem, but at least I can reproduce it; I
cooked a very simple program to show what's going on (attached), maybe
someone more skilled can help me!

[Fremantle] Compositing is disabled in fullscreen
I know that compositing is disabled in fullscreen, as some composited widget (for example the fullscreen button in hildon-extras) are shown with a black background instead of a semi-transparent one. But I noticed one thing: if a hildon-banner appears in fullscreen when one of such widgets is on the screen, the window manager turns compositing on (the translucid background of the other widget is shown), just to turn it off when the banner disappears. Is there a way to trick the window manager to act the same for arbitrary widgets as for hildon-banners? -- Luca Donaggio ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
