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()
