@SGaist has tried to help.

You haven't explained what it is you want to do.

If it's set the icon while an application is running, you can use QMainWindow::setWindowIcon().

If it's set the icon for a desktop launcher, you'll have to create a .desktop file and put it on the right place. Mine happens to look like:

[Desktop Entry]
Version=1.0
Type=Application
Name=Jinn
Icon=jinn.png
Exec=python3 "Jinn/Code/home.py"
Comment=Jinn Application
Categories=Application
Terminal=false

Where that goes depends on desktop manger. Which you have not specified.

I don't have time right now to type any more, see how you go.

@vaibs

I want set icon after run application in qt

Then if you're not trying to have the icon as a clickable link on your desktop, but simply to show up as the icon for the application once you run it, you won't need a .desktop file, you'll only need the QMainWindow::setWindowIcon().

But i want this work on ubuntu

That's why I gave you a working example on Ubuntu.

Can you please share how you solved it ?

@SGaist
Solved it by using QMainWindow::setWindowIcon() for setting icon .
Thank you...

QMainWindow::setWindowIcon("name _of_png_file");
