nanogui: Thread: Default Back color

Hi,

is there a way to change the nano-x back color. I would like to have 
a different back color then black.

Kind Regards

The launcher demo has that feature. If you comment out the  
$window_background_image line in launcher.cnf and uncomment  
$window_background_colour it will set a solid background colour  
instead of a background image.

If it doesn't work, you're not hitting it with a big enough hammer

thanks it does indeed change the default back color.

but when i now move a window into the screen, still the nanox blacks 
the screen buring the update.

what i do is the following.

Create a actual window at -320 and -640 so it is out od the visible bounds.

then when the painting is done, i move it to 0,0 so the full screen is filled.

but when i do the move the bakcground flashes to black

any suggestions here

Regards

Thanks for the help but never mind this email below.

fixed it on a different way:

don't do the move window but create the window in place with 
GR_WM_PROPS_NOBACKGROUND...

At least it seems to be faster. ;-)

: but when i now move a window into the screen, still the nanox blacks 
: the screen buring the update.
: but when i do the move the bakcground flashes to black

When a window is exposed, including the root window, which
is the screen background, the nano-X server will paint the
specified background color before sending an EXPOSE
event to the application in control of the window.  If the
nanowm window manager isn't running, then the root window
will always be cleared to its initially specified background color:
black.  To change this, you can specify a different color in
nanox/srvmain.c::GsInitialize().  Set wp->background to
the color you desire.

Also, as you've found, if you specifiy
GM_WP_PROPS_NOBACKGROUND, then the server
won't clear any color, it just sends the expose event.  When
nanowm isn't running, nothing will happen.  Its probably
not a good idea to set this flag on the root window.
