python - 如何使用 pyqt 和 py2app 将 "About box"添加到 Mac 应用程序？

Question

我正在使用 PyQt，为了将我的应用程序打包到 Mac，我正在使用 py2app。

如何将“关于框”添加到主菜单:

看起来像这个例子:

Answer 1

要在那里添加“关于”菜单，您只需将其添加到 menuBar() 的 Help 子菜单中即可。

import sys
from PySide import QtGui, QtCore

class Window(QtGui.QMainWindow):
    def __init__(self):
        super(Window, self).__init__()
        help_menu = QtGui.QMenu('&Help')
        about = help_menu.addAction('&About')
        about.triggered.connect(self.show_about)
        self.menuBar().addMenu(help_menu)

    def show_about(self):
        print 'shown'

app = QtGui.QApplication(sys.argv)
win = Window()
win.show()
app.exec_()

问题是应用程序的标题将是python，而About将是About python。要改变这一点，由于您已经使用 py2app，您应该查看 this question

对于 PyQt4 来说有点不同。请参阅documentation .

两个相关的事情:

1. Do not call QMainWindow.menuBar() to create the shared menu bar, because that menu bar will have the QMainWindow as its parent. You must create a menu bar that does not have a parent.

   menuBar = QtGui.QMenuBar(None)

2. The application name is fetched from the Info.plist file (see note below). If this entry is not found no About item will appear in the Application Menu.
