Qt for Python

multimedia should have automically been added to the plugins by the tool itself (atleast in 6.8.1 as i check with an example). So, if anyone stumbles upon this, please use the latest version of PySide6 and check.

@LingHan said in PySide6 gets stuck in QtWidget.setVisible():

I should redesign my program and use front-end code to call my back end algorithms, rather than the other way around.

Yes. You should create a single QApplication instance and call QApplication.exec() as the last step from main(). It does not return until the user quits. All your UI code must be in the main thread, the one where the QApplication is created. You can do background/computation code in secondary threads, either long running one(s) or short-lived. The Qt thread code runs an event loop in each thread, so you can send it signals (e.g. to start something off) and it can send signals back to your main (e.g. when it has finished something or wants the UI to show something on its behalf).

it worked, i realized my QVlayout was just floating in the window, so i attached it to the window with grid layout.

@JonB Oh no another option

Thank you for your answers,
It appears I made a simple mistake in the actual code.
The garbage collector removed the object. Additionally, when an error occurs, it emits a signal immediately, and my connection isn't functioning as @GrecKo described.

Hi and welcome to devnet,

What are these pages ?
Are the pages all the same widget or each page has its own widget ?

I guess you need to use msg.show().

Here's an example I've made that anyone can run, you will need to replace self.path_to_tray_image to a path of an image in order for it to actually appear in the system tray.

self.path_to_tray_image = "C:/Users/username/Downloads/image.png" import sys from PyQt6.QtWidgets import QApplication, QMainWindow, QPushButton, QSystemTrayIcon, QMenu from PyQt6.QtCore import QPoint from PyQt6.QtGui import QIcon, QAction, QCursor class TrayApplication(QMainWindow): def __init__(self): # replace to your tray image self.path_to_tray_image = "C:/Users/username/Downloads/image.png" super().__init__() self.setWindowTitle("Tray Example") self.setGeometry(100, 100, 400, 300) # Create a button to minimize to tray self.minimize_button = QPushButton("Minimize to Tray", self) self.minimize_button.setGeometry(150, 120, 100, 40) self.minimize_button.clicked.connect(self.minimize_to_tray) # Set up the system tray icon self.tray_icon = QSystemTrayIcon(self) self.tray_icon.setIcon(QIcon(self.path_to_tray_image)) # Replace with your icon file # Add a context menu to the tray icon self.tray_menu = QMenu() quit_action = QAction(QIcon(":/path_to_exit_action_image"), "Quit", self) # Replace with your icon file quit_action.triggered.connect(self.close_application) self.tray_menu.addAction(quit_action) # Connect the tray icon activation event self.tray_icon.activated.connect(self.tray_icon_clicked) def minimize_to_tray(self): self.hide() self.tray_icon.show() def restore_from_tray(self): self.show() self.tray_icon.hide() def tray_icon_clicked(self, reason): # Left click if reason == QSystemTrayIcon.ActivationReason.Trigger: self.restore_from_tray() # Right click elif reason == QSystemTrayIcon.ActivationReason.Context: # Get the current cursor position cursor_pos = QCursor.pos() # Calculate the menu position: align bottom-right corner of the menu to the cursor menu_width = self.tray_menu.sizeHint().width() menu_height = self.tray_menu.sizeHint().height() pos = QPoint(cursor_pos.x() - menu_width, cursor_pos.y() - menu_height) # Show the menu at the calculated position self.tray_menu.popup(pos) def close_application(self): self.tray_icon.hide() self.close() if __name__ == "__main__": app = QApplication(sys.argv) window = TrayApplication() window.show() sys.exit(app.exec())

pyside6-deploy doesn't encrypt your source code—it packages it into the executable. To protect the code, you might want to obfuscate it using tools like pyarmor or [cython](https://syntaxscenarios.com/python/scientific-notation/).

For the QML and image files issue, you can include them in the executable by modifying your .spec file if you're using PyInstaller. Add:

datas = [ ('qml', 'qml'), ('images', 'images') ]

Then in the Analysis section:

a = Analysis( ['main.py'], datas=datas, ... )

This ensures the QML and images are bundled inside the executable. Let me know if you need further clarification!

@JETouma Can you solve the problem?

The issue was that I had python311.dll but didn't have python3.dll. Adding the python3.dll file resolved the problem.

@igonro That's the sexiest MWE I've ever "scene"!

@parth07sm Then read "Selecting a mirror for opensource" in https://wiki.qt.io/Online_Installer_4.x - it even shows what to do.

@ktechhydle If you enter "qt6 QWindow OpenGL" in Google first result is: https://doc.qt.io/qt-6/qtopengl-openglwindow-example.html

@JonB said in Fast loading of complex interfaces:

Just one thing: let's say you leave it as-is because you don't want to divide it for whatever reason. Are you at least aware that Qt has a QSplashScreen?

Didn't know that. I'll use it. tnx

@jsulm said in Fast loading of complex interfaces:

you can still design ui widgets for different parts of the user interface using designer.

I think I'll do what you wrote. Thank you.

@Shyamnath How do I add project data files (images and QML files) to the pysidedeploy.spec file so that the generated executable file can be run anywhere?Because my data files are not being added.
