Trackbar not working (window not showing)
Hi, I have the problem that the windows in which I create a trackbar are simply not showing and keystrokes are not registered by waitKey. An example code would be the one from the tutorial (http://opencv.itseez.com/2.4/doc/tuto...), although I have tried many codes that should work but won't when I compile and execute them. If I remove the trackbar from the window it shows again and everything works. I am using Xubuntu and C++.
Thank you!
Edit: I am using XFCE and version 2.4.13.
what kind of gui do you use ? how did you install opencv ? which opencv version ?
I am using XFCE. I installed opencv version 2.4.13 using these instructions: http://docs.opencv.org/2.4/doc/tutori...
ah, ok. the gui question would have been more like gtk vs. Qt, and i was suspecting, you got some prebuild libs from some ppm, which somehow don't fit.
no idea now, unfortunately !
