PyQt - 隐藏 MainWindow 并显示 QDialog 而没有任务栏图标消失

问题描述

我一直在使用此示例中的代码 PyQt:如何隐藏 QMainWindow:

I've been using the code from this example PyQt: How to hide QMainWindow:

class Dialog_02(QtGui.QMainWindow):
    def __init__(self, parent):
        super(Dialog_02, self).__init__(parent)
        # ensure this window gets garbage-collected when closed
        self.setAttribute(QtCore.Qt.WA_DeleteOnClose)
    ...    

    def closeAndReturn(self):
        self.close()
        self.parent().show()

class Dialog_01(QtGui.QMainWindow):
    ...

    def callAnotherQMainWindow(self):
        self.hide()
        self.dialog_02 = Dialog_02(self)
        self.dialog_02.show()

它可以工作，但是当打开第二个窗口时，窗口的任务栏图标不显示.我也尝试将 QtGui.QDialog 用于 Dialog_02，但这给了我相同的结果.

It works, however when opening a second window, the window's task bar icon doesn't show. I've tried using QtGui.QDialog for the Dialog_02 as well but that gives me the same result.

我该如何解决这个问题?

How do I go about solving this?

我使用的是 Windows 10

推荐答案

只是猜测(因为我不知道你在什么平台上，而且我自己不使用任务栏，所以我无法真正测试它)，但尝试摆脱父母:

Just guessing (because I don't know what platform you're on, and I don't use a task-bar myself, so I cant really test it), but try getting rid of the parent:

class Dialog_02(QtGui.QMainWindow):
    def __init__(self, other_window):
        super(Dialog_02, self).__init__()
        # ensure this window gets garbage-collected when closed
        self.setAttribute(QtCore.Qt.WA_DeleteOnClose)
        self._other_window = other_window
    ...    

    def closeAndReturn(self):
        self.close()
        self._other_window.show()
