There is a class on QWidget that should not open as a second window, so I use Qt.WindowType.Popup. Everything works correctly until you click past the application window. The event reports that a click was made past the application window, but when I change focus to another application or desktop, my widget closes, which I don't need. Therefore, I tried to redefine the focus change event, but print("The focus is lost, but the window remains open.") does not work at all.
class AddFriendWidget(QWidget):
def __init__(self, main_window):
super().__init__()
self.main_window = main_window
self.init_ui()
def init_ui(self):
# Layout and widgets
self.setFixedSize(300, 150)
add_friend_layout = QVBoxLayout(self)
self.info_label = QLabel("Enter friend's username:")
add_friend_layout.addWidget(self.info_label)
self.friend_input = QLineEdit()
self.friend_input.setPlaceholderText("Friend's username")
add_friend_layout.addWidget(self.friend_input)
self.add_button = QPushButton("Add Friend")
self.add_button.clicked.connect(self.add_friend)
add_friend_layout.addWidget(self.add_button)
self.cancel_button = QPushButton("Cancel")
self.cancel_button.clicked.connect(self.close)
add_friend_layout.addWidget(self.cancel_button)
self.setWindowFlags(Qt.WindowType.FramelessWindowHint | Qt.WindowType.Popup)
self.installEventFilter(self)
return self
def add_friend(self):
"""Handle adding friend logic here."""
friend_name = self.friend_input.text().strip()
if friend_name:
print(f"Friend '{friend_name}' added.")
else:
self.info_label.setText("Please enter a valid username.")
def eventFilter(self, source, event):
if event.type() == QEvent.Type.MouseButtonPress:
global_pos = event.globalPosition().toPoint()
if not self.main_window.geometry().contains(global_pos):
print("Clicked OUTSIDE the entire application!")
elif not self.geometry().contains(global_pos):
print("Clicked outside the widget, but inside the main window.")
else:
print("Clicked inside the widget!")
print(self.isVisible())
return True
if event.type() == QEvent.Type.FocusOut and isinstance(event, QEvent.FocusOut):
if event.reason() == Qt.FocusReason.ActiveWindowFocusReason:
print("The focus is lost, but the window remains open.")
event.ignore()
return True
return super().eventFilter(source, event)
