No output on framebuffer
Message 1 in thread
Hello list,
I've prepared a small application with a single QPushButton that
does nothing. I can compile the program with no errors, but
when I run it (./qt-test -qws) only the green "desktop" background
and the mouse cursor is displayed, while the button is not painted.
It seems like I can actually see what lies "under" the qtopia
application (in my case the linux console from where I started my
test app).
I can give some further informations: I'm using an ARM PXA320 cpu,
qtopia-core-opensource-src-4.3.2, cross-compiling everything with
an arm-linux-gxx tested toolchain using no particular compiling
flags. I'm working with a linuxfb device, and the test program provided
with qtopia (examples/qtopiacore/framebuffer) works perfectly with
both 8bpp and 16bpp.
Where am I wrong? Can anybody help me?
Many thanks,
Giorgio

Hello !
It is maybe an "error" in your code... Could you send your code by mail ? I (we) could test it and maybe find something ...
Cheers,
Guillaume
