From the QMouseEvent reference, "If you move the widget as a result of the mouse event, use the global position returned by globalPos() to avoid a shaking motion. This mechanism is widely used: as of the Event Delivery and Propagation¶. For the case of this tutorial I want to hide this warning each time the program runs: DeprecationWarning: PySide6. Qt automatically PySide2. The main window with all widgets looks great already. Each class subclasses QEvent and adds event-specific functions. QRubberBand class reference). main. While this generally works for simple cases and basic widgets, it's also usually discouraged, and especially for event handlers: 1. QMouseEvent events are created for each and every mouse movement and button click on a widget. in which the QWidget is the type the the event handler is installed to, the QMouseEvent is the event that causes the handler to be called, and the mouse_event is the handler.

You can trigger behaviors in response to user input, such as button presses or text input, or events in your own code. The button that caused the event is given as a value from the python; qt; user-interface; pyqt; Share. (See Python states for the basics of how to implement a custom viewer state.
