I think the code speaks for itself
import sys
from PyQt4 import QtCore, QtGui, QtWebKit
"""Html snippet."""
html = """
<html><body>
<center>
<script language="JavaScript">
document.write('<p>Python ' + pyObj.pyVersion + '</p>')
</script>
<button onClick="pyObj.showMessage('Hello from WebKit')">Press me</button>
</center>
</body></html>
"""
class StupidClass(QtCore.QObject):
"""Simple class with one slot and one read-only property."""
@QtCore.pyqtSlot(str)
def showMessage(self, msg):
"""Open a message box and display the specified message."""
QtGui.QMessageBox.information(None, "Info", msg)
def _pyVersion(self):
"""Return the Python version."""
return sys.version
"""Python interpreter version property."""
pyVersion = QtCore.pyqtProperty(str, fget=_pyVersion)
def main():
app = QtGui.QApplication(sys.argv)
myObj = StupidClass()
webView = QtWebKit.QWebView()
# Make myObj exposed as JavaScript object named 'pyObj'
webView.page().mainFrame().addToJavaScriptWindowObject("pyObj", myObj)
webView.setHtml(html)
window = QtGui.QMainWindow()
window.setCentralWidget(webView)
window.show()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
Some references:
A minor thing to note is that you should ensure you re-add your object to the window every time the javaScriptWindowObjectCleared() signal is emitted too. There's a C++ example of this on my blog post http://www.kdedevelopers.org/node/4008
ReplyDeleteWow! I've been looking for a way to do this for a week straight! This is miles ahead of anything I was able to find for Python-Gobject. And it's from 2010, good lord...
ReplyDeleteAll the day with "Python-Gobject" search too, reading c++ code, and here is! clear and well commented code! Thank you!!!
ReplyDeleteYou're welcome! Glad I can help
ReplyDeleteIs there anyway to connect with an onItemClick in a loaded .js file? It seems not to work when the code is loaded from a .js on disk.
ReplyDeleteSorry, don't know. Haven't been playing anymore with this in years.
ReplyDeleteThanks a lot!!
