从 unicode 字符串 pyqt pyside 发送击键

Question

我需要在 pyqt4 或 pyside 中模拟击键，我已经有了以下代码，但它只添加了大写拉丁字母，不允许使用小写字母或其他语言字母

def sendkeys(self, char, modifier=QtCore.Qt.NoModifier):
    event = QtGui.QKeyEvent(QtCore.QEvent.KeyPress, char, modifier)
    QtCore.QCoreApplication.postEvent(self, event)

def sendstring(self, string):
    for chara in string:
        print(chara)
        self.sendkeys(char=QtGui.QKeySequence.fromString(str(chara))[0])

这是一个完整的例子，可以让这个想法与拉丁字母一起工作

from PySide import QtCore, QtGui, QtWebKit


class WebPage(QtWebKit.QWebPage):
    """
    QWebPage that prints Javascript errors.
    """

def javaScriptConsoleMessage(self, message, lineNumber, sourceID):
    print('Javascript error at line number %d' % lineNumber)
    print('%s' % message)
    print('Source ID: %s' % sourceID)


class myWindow(QtWebKit.QWebView):
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)
        self.loadFinished.connect(self.on_loadFinished)
        self.runloadfinished = True
        self.web_page = WebPage()
        self.setPage(self.web_page)
        self.load(QtCore.QUrl('http://stackoverflow.com/'))
def on_loadFinished(self):
    if self.runloadfinished:
        self.sendkeys(QtCore.Qt.Key_Tab)
        self.sendstring('Hello World')
        self.sendkeys(QtCore.Qt.Key_Enter)
        self.sendkeys(QtCore.Qt.Key_Return)
        self.runloadfinished = False

def sendkeys(self, char, modifier=QtCore.Qt.NoModifier):
    event = QtGui.QKeyEvent(QtCore.QEvent.KeyPress, char, modifier)
    QtCore.QCoreApplication.postEvent(self, event)

def sendstring(self, string):
    for chara in string:
        print(chara)
        self.sendkeys(char=QtGui.QKeySequence.fromString(str(chara))[0])


if __name__ == "__main__":
    import sys

    app = QtGui.QApplication(sys.argv)
    app.setApplicationName('myWindow')
    main = myWindow()
    main.show()
    sys.exit(app.exec_())

对于将来需要答案的任何人，我已经在 upwork.com 上雇用了一个人并得到了答案，这是一个完整的工作示例，它适用于 python 2 和 3、pyqt 和 pyside

from PySide import QtCore, QtGui, QtWebKit


class WebPage(QtWebKit.QWebPage):
    """
    QWebPage that prints Javascript errors.

    def javaScriptConsoleMessage(self, message, lineNumber, sourceID):
        print('Javascript error at line number %d' % lineNumber)
        print('%s' % message)
        print('Source ID: %s' % sourceID)


class myWindow(QtWebKit.QWebView):
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)
        self.loadFinished.connect(self.on_loadFinished)
        self.runloadfinished = True
        self.web_page = WebPage()
        self.setPage(self.web_page)

        else:

    def sendstring(self, string):
        for chara in string:
            print(chara)

            # QtCore.QString() is missing when using PyQt4 for Python3
            # since str() is unicode by default on Python3

            try:
                text = QtCore.QString(chara)
            except AttributeError:
                text = str(chara)

            self.sendkeys(char=QtGui.QKeySequence.fromString(str(chara))[0],

    main = myWindow()

    sys.exit(app.exec_())

没有深入研究。我会寻找一种方法来限制你的 Unicode 设置为严格的 ASCII 说 128...

[chr(x) for x in range(128)] --> 显示值..
