QT Application icon disappears after application restart

Noturnoz

I am using .desktop file for running my application. First time I run it the icon loads correctly, but whenever my application restarts from the code then the application is started without the icon.

I use this code to restart my application (I think it is from documantation):

@QString app = QApplication::applicationFilePath();
QStringList arguments = QApplication::arguments();
QString currPath = QDir::currentPath();
QProcess::startDetached(app,arguments,currPath);
QApplication::exit();@

I know it does not work because it runs directly the binary file and not the .desktop file. I'd like to ask if there is a way to restart it and load the icon file.

Hi and welcome to devnet,

Did you saw the "Setting the Application Icon" chapter of Qt's documentation ? It should contain the information you need

Hope it helps

Well as far as I know the documentation does not say how to load the icon after in-code appplication restart.

AFAIK (I may be wrong though) it's done be the desktop environment, which one are you using ?

Noturnoz

Gnome and KDE. But for now I am trying to get it working on Gnome.

Then you should also check with the Gnome people
