问题 I am trying to give focus to a window if the user clicks on another window. Right now i have two windows: Window A is behind, and Window B is in front. When Window B appears, it disables Window A. Now what i want is that whenever the user clicks outside of Window B, it should give focus back to Window B. Here is the code for Window B: class window_b(QtGui.QDialog): def __init__(self,parent=None): super(window_b, self).__init__(parent) window_a.setEnabled(False) self.ui = Ui_Form_window_b()

I've read that the issue has been resolved in the later models but I am still experiencing this error. I have the latest version of anaconda and pyqt5. I read a git thread that asked to use 5.9.2 version of pyqt but that did not solve the error either. This is the command I'm using to create an executable

问题 How can I implement a progress bar in a pop-up window that monitors the progress of a running function from a so-called Worker class (i.e. time/CPU-consuming task) by means of a QThread ? I have checked countless examples and tutorials, but the fact that the progressbar shows up in a pop-up window seems to make everything harder.
