Could be completely unrelated, but I’ve noticed issues with multiple Qt applications with their Dialog boxes as well, e.g. Audacious whilst trying to open any directory. There’s a Python code to replicate such issue (try to run the code below and select any directory):
from PyQt5 import QtCore
from PyQt5.QtWidgets import QFileDialog, QApplication, QWidget
import os
import sys
class App(QWidget):
def __init__(self):
def receive():
dirs = dialog.selectedFiles()
print(dirs)
super().__init__()
dialog = choose_file_dialog(self, "Choose wisely!", want_folder=True)
dialog.open(receive) # Open and cancel buttons don't do anything on KDE, breaks here.
dialog.exec()
sys.exit()
def choose_file_dialog(parent, title, want_folder=True):
options = QFileDialog.Options()
if want_folder:
options |= QFileDialog.ShowDirsOnly
dialog = QFileDialog(parent, title, os.path.expanduser('~'), options=options)
dialog.setFileMode(QFileDialog.Directory if want_folder else QFileDialog.ExistingFiles)
dialog.setParent(parent, QtCore.Qt.Sheet)
return dialog
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
Expected behavior would be:
Open should pass the selected path back to the application and close the Dialog box
Cancel closes the Dialog
For me, neither of those 2 expected behaviors could be replicated with the latest KDE. As far as I’m aware, the code works fine with Gnome.
