Unity Launcher Icon Not Installed by Qt

Question

I am trying to get the Qt application to display an icon in Unity Launcher, but it does not work. In the code, I just use:

qApp->setWindowIcon(QIcon("path/to/icon.png")); 

but he does nothing. I also tried to set the icon directly in the main window, but that doesn't help either.

Any idea what could be the problem?

PS: I checked the icon path and that is correct.

Without knowing the details of unity, I am sure that you will need to create and install a .desktop file with an icon in it. See for example here . Regardless of what you installed at run time, the launcher cannot know about it before launching the application, so it will need information from an external configuration.

To enable image encoding on Windows (not Ubuntu), I placed the QT \ 4.8.3 \ plugins \ imageformats folder next to my application. I think you should try the same thing.
