Taking the example program as an example, when I change the example to inherit from QDialog, the maximize button in the sample program cannot maximize the window; it only moves the window slightly downward with a white border added above; In the example, inheriting from QWidget/QMainwindow does not cause this issue.
Additionally, in the sample program, when you click the Pin button, although the window can be fixed, the overall window moves down by a certain distance.
