 |
|
Hi there,
I'm writing an application using libX11 which is showing the frames
recorded by a camera. Everythimg is working quite well, but I want my
application beeing shown as a fullscreen application taking the full
resolution 1920x1200 of my screen...
How may I do this?
Any help welcome
Thanks and best regards,
Johann |

Dear Jan,
Thank you for your hints.
I solved it by
- using fluxbox as the window manager
- and disabling all window decorations (see this link:
http://fluxbox.sourceforge.net/docs/en/faq-dev.php)
And: it works perfect!
Best regards
Johann |

Well, you could open a window of 1980x1200,
but then you would still need to scale your camera output.
That last part (scaling) is something special all by itself.
What you could do, to make it easier on yourself,
is write the output in mjpegtools YUV format, and pipe for example to mplayer
your_app | mplayer -fs -.
I do this with mcamip, http://panteltje.com/panteltje/mcamip/
it has its own simple X window in 640x480, but you can pipe it via mplayer,
or via y4mscaler to anything else.
As an alternative, perhaps more what you want,
you could also have a look at this simple library:
http://www.sourceforge.net/projects/tinyptc/
I have used it to scale pictures to full screen without borders in X11,
it is a really small library. |

As far as your subject is concerned, you need to tell the window manager
that your window doesn't want any decoration. Actually, there are some
standard ways to solve this, though not every WM supports them. What I
would look at is the sources to fspanel (though any similar one would
probably work, too). This panel just tells the WM that it is part of the
desktop and not an application window, so the WM doesn't add any
decoration.
BTW: your solution also works, but it isn't generally portable.
