qt-5.7.1, gtk-3.0, input device
-
Does anyone occur to run a qt app and a gtk app together? I run a gtk app first, mouse and keyboard can work, then I run a qt app in backstage, I guess mouse and keyboard focus on the qt app now, cos the gtk app can't capture the mouse and keyboard event, and when I killed the qt app process, the gtk app works fine. BTW, they both run in fullscreen. Anyway, help !!! and thx in advance.

Hi and welcome to devnet,
You have to give more details about your setup.
What Linux distribution are you running ?
What window manager ?
How do you start your applications ? -

Linux distribution
oh, sorry, new here.
Actually, I'm running on a embedded device, it's a tidy linux filesystem and no gnome, window manager is X11.
This is how I start X11: /home/mybin/Xorg -pixmap32 vt13 -config /etc/X11/xorg.conf &; export DISPLAY=:0.0.
cat /etc/X11/xorg.conf:This is a minimal sample config file, which can be copied to
/etc/X11/xorg.conf in order to make the Xorg server pick up
and load xf86-video-fbturbo driver installed in the system.
When troubleshooting, check /var/log/Xorg.0.log for the debugging
output and error messages.
Run "man fbturbo" to get additional information about the extra
configuration options for tuning the driver.

How I start applications :
./gtk-app-name
and then :
./qt-app-name &
and then :
killall qt-app-nameand if I start qt app first, like :
./qt-app-name &
and then :
./gtk-app-name
mouse can work for gtk app, but keyboard can't, and now I can sure that the keyboard still focus on the qt app.
Thank you for your reply. -
How did you compile Qt ?
It sounds like the Qt application only serves as some sort of splash screen.
Can you explain a bit more how your system should be working ?
