This problem is not because of external/dual monitors. This happens when the
context menu has no parent and you right click the widget when its parent
window is not focused. I know this because I recently wrote a simple PySide6
myself and had this exact same problem, and after spending a lot of time, I
discovered the reason.
So, this problem can be reproduced in the say way in Plasma desktop. Open any
window (not maximised) and click to focus that window. Then, directly
right-click the desktop. Since the desktop (desktop context menu's parent) is
not focused, it's opened as a pop-up. This also happens with the Up arrow in
the notification area that shows hidden items.
Below is a simple code to demonstrate this problem. Right-click both text boxes
when the window is NOT focused (i.e. click some other window).
from PySide6.QtGui import QAction, QIcon, Qt
from PySide6.QtWidgets import QApplication, QMainWindow, QWidget,
QVBoxLayout, QTextEdit, QMenu
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.resize(600, 400)
self.context_menu1 = QMenu()
menu_item1 = QAction(QIcon.fromTheme("edit-copy"), "I have no
parent", self)
self.context_menu1.addAction(menu_item1)
self.context_menu2 = QMenu(self)
menu_item2 = QAction(QIcon.fromTheme("edit-copy"), "I have a
parent", self)
self.context_menu2.addAction(menu_item2)
self.widget1 = QTextEdit()
self.widget1.setText("Context menu NO parent")
self.widget1.setContextMenuPolicy(Qt.CustomContextMenu)
self.widget1.customContextMenuRequested.connect(self.show_custom_context_menu1)
self.widget2 = QTextEdit()
self.widget2.setText("Context menu WITH parent")
self.widget2.setContextMenuPolicy(Qt.CustomContextMenu)
self.widget2.customContextMenuRequested.connect(self.show_custom_context_menu2)
layout = QVBoxLayout()
layout.addWidget(self.widget1)
layout.addWidget(self.widget2)
self.central_widget = QWidget()
self.central_widget.setLayout(layout)
self.setCentralWidget(self.central_widget)
def show_custom_context_menu1(self, point):
self.context_menu1.popup(self.widget1.viewport().mapToGlobal(point))
def show_custom_context_menu2(self, point):
self.context_menu2.popup(self.widget2.viewport().mapToGlobal(point))
app = QApplication([])
win = MainWindow()
win.show()
app.exec()
