Question

我正在尝试使用WebView在pyqt中开发漂亮的应用程序并且有一点问题。我想通过在WebView中按下按钮来创建新窗口。

我有主窗口（ 简短视图 ）：

class LoginWindow(QWidget):
    def __init__(self):
        # creating window and different properties...
        # Its not important,i think.

        self.foo = LoginConnector(self)
        view.page().mainFrame().addToJavaScriptWindowObject("foo", self.foo)

... JS连接器

class LoginConnector(QObject):

@pyqtSlot(result=str)
def get_user_list(self):
    return ','.join(core.available_users())

@pyqtSlot()
def new_window(self):
    print 'Hello!'  
    #What can i do here?

@pyqtSlot()
def quit(self):
    QApplication.quit()

当我在窗口中按下按钮时，它从LoginConnector调用new_window（），但是如何在LoginConnector中创建Dialog？

看看api文档。 http://pyqt.sourceforge.net/Docs/PyQt4/classes.html 如果你不喜欢这个，那么PySide与语法上的一些差异基本相同。 http://pyside.github.io/docs/pyside/

class LoginWindow(QWebView):
    def __init__(self, *args, **kwargs):
        super(QWebView, self).__init__(*args, **kwargs):

        ...
        self.foo = LoginConnector(self)

        self.loadPage("httpdocs/login.hmtl")
    # end Constructor

    def loadPage(self, web_page):
        """Loads a web page in the browser.

        Args:
            webPage (str): The URL of the desired web page with JavaScript Python Communication.
        """
        # Inspector - right click inspect to debug javascript and have access to the console.
        inspector = QtWebKit.QWebInspector()
        inspector.setPage(self.page())

        # Force relative path otherwise you get a does not except file:// error
        if os.path.isabs(web_page):
            web_page = os.path.relpath(web_page)

        url = QtCore.QUrl(web_page)
        self.load(url)
        self.frame = self.page().mainFrame()
        self.frame.addToJavaScriptWindowObject("foo", self.foo)
    # end loadPage
# end class LoginWindow


class LoginConnector(QObject):
    @pyqtSlot()
    def new_window(self):
        self.dialog = QDialog()
        self.dialog.show() # or exec
    # end new_window
# end class LoginConnector

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)

    window = LoginWindow()
    window.show()

    sys.exit(app.exec_())

这是PySide的主要应用程序结构。 PyQt应该是类似的。
