The icons in the window toolbar (GUI built with QT) have no visible icons and are basically invisible though they same to work.

Also describe here.

Hi Steven. What are the options when you configured cmake?

I'll try upgrading Qt 5.2.1 to 5.3 to see if there's a difference.

It works with Qt 5.3.

Hi there!
I'm having the very same issue with missing icons while using QT4.
Based on this thread, I realize that I'd better upgrade to QT5.3.
But are there any good instructions on how to configure my OpenCV project with using QT5.3?
I followed these instructions to install QT5: http://www.sysads.co.uk/2014/06/install-qt-5-3-1-in-ubuntu-14-04/
But I'm not sure what's next. OpenCV cmake doesn't find the QT5 libs and trying to redirect it to the folder doesn't really work for me.
Am I missing anything?
I'm using OPenCV 2.4.6, Ubuntu 14.04.

Thanks in advance!

Several problems in your approach

1. Use OpenCV 2.4.9, several bugs related to Qt were fixed in the last months
2. Use cmake-gui and manually select all your Qt paths needed

Then it should work perfectly fine
