Hi,
I trying show icon in window but is not visible in window.
bellow attaching some sample what i tried

from PySide2.QtWidgets import QApplication, QWidget
import sys
from PySide2.QtGui import QIcon



class Window(QWidget):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Setting Icon")
        self.setGeometry(300,300, 500,400)
        self.setWindowIcon(QIcon("sharp-osa.png"))

myApp = QApplication(sys.argv)
window = Window()
window.show()


myApp.exec_()
sys.exit(0)

is something missing in code.
Python version3.8.2

Is not setting icon in window left corner, setting icon as application icon

If fileName contains a relative path (e.g. the filename only) the relevant file must be found relative to the runtime working directory.

One guess: file not found. How do we know where your file is and what the app's working directory is?

Or: do we even know if GNOME sets any window icons "in window left corner", I'm not sure I've seen that anywhere else?

@yashi95 said in Window icon is not visible.:

I am not getting any error like "file not found" icon

There would be nowhere for an error to come from, if it were the case. I do not know whether GNOME would show any "red cross".

I previously said:

If you think it should be setting a "window left corner" icon, can you show me any GNOME window which has that? Is it supported?

I only know you can set a GNOME application icon, which shows in the taskbar.

Hi,

I think you have to call QApplication::setWindowIcon for that one.

If not working, then take a look here.

You can use QApplication.setWindowIcon().

In your code:

myApp = QApplication(sys.argv)
myApp.setWindowIcon(QIcon("sharp-osa.png"))
window = Window()
window.show()
