阅读更多关于 PyQt QToolButton not updating icon when in focus

问题 I'm having a problem updating the icon of a button set with QToolButton . The idea is to use the button for a movie player. To play, one presses the button and the icon changes to pause.

If I keep the Qt window in focus, it takes one or two button presses to change the icon to the intended image, by which time the actual image is not the

问题 I am trying to track my keypresses, using the module "keyboard" while a PySide2 Widget is not in focus, which works fine. However when I try to create a new Widget using a "keyboard" shortcut the program crashes. Opening a window on a button press works fine. I can also call non UI functions using "keyboard" eg. the print function without any problem. Do you know a way to fix this and open a new window using "keyboard" or any other method, while a PySide2 window is not in focus. In this

问题 I want to make QlineEdit fields double-clickable, so that a user's double-clicking on a QlineEdit field (e.g., 'qle01') calls a function.

In my script below, if qle01 was double-clicked, my goal is to have line 9 print, "The QLineEdit field's
