Can anyone tell me why the program is not showing 'hello' and just showing a simple white screen?

When I try to run this, it starts and runs perfectly fine with no error and a white screen just like any other normal PySide6 program but it doesn't show the text that i expected to see.

from PySide6.QtWidgets import *
from PySide6.QtCore import *
from PySide6.QtGui import *

class View(QGraphicsScene):
    def __init__(self):
        super().__init__()
        self.addText("Hello!")
        self.scene = QGraphicsView(self)
        self.scene.show()

app = QApplication([])
View()
app.exec()

i expected a white screen with hello text but there's just a white screen with nothing

Solution

  • You are not doing assigning View object to any variable, so it gets garbage collected nearly immediately. Assign it to something and it will stay open: window = View()
