PyQt窗口焦点 [英] PyQt Window Focus

问题描述

如果用户单击另一个窗口，我试图将焦点放在一个窗口上.

I am trying to give focus to a window if the user clicks on another window.

现在我有两个窗口:窗口A在后面，窗口B在前面.当窗口B出现时，它禁用了窗口A.现在我想要的是，每当用户单击窗口B之外时，它都应将焦点重新分配给窗口B.

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.

这是窗口B的代码:

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()
        self.ui.setupUi(self)
        self.setFocusPolicy(QtCore.Qt.StrongFocus)

    def focusOutEvent(self,event):
        self.setFocus(True)
        self.activateWindow()
        self.raise_()
        self.show()

我尝试了setFocus和activateWindow，但是并没有将焦点返回到窗口B.

I tried setFocus and activateWindow, but it didnt give focus back to Window B.

有什么建议吗?

推荐答案

要使window_b始终保持在顶部，您必须添加windowflag QtCore.Qt.WindowStaysOnTopHint.在您的__init__中添加通话

To get window_b to always stay on top you have to add the windowflag QtCore.Qt.WindowStaysOnTopHint. In your __init__ add the call

self.setWindowFlags(PyQt4.QtCore.Qt.WindowStaysOnTopHint)

我必须补充一点，这仅是窗口管理器的提示，不能保证成功.

I have to add that this only is a hint to the windowing manager and not guaranteed to succeed.
