Using Qt Creator’s QML Debugger for a PySide6 QML Application#
Besides the C++ debugger, Qt Creator provides a QML debugger which lets you
inspect JavaScript code. It works by connecting to a socket server run by the
QmlEngine
instance. The port is passed on the command line. To enable it,
add the below code to your QML application:
from argparse import ArgumentParser, RawTextHelpFormatter
...
if __name__ == "__main__":
argument_parser = ArgumentParser(...)
argument_parser.add_argument("-qmljsdebugger", action="store",
help="Enable QML debugging")
options = argument_parser.parse_args()
if options.qmljsdebugger:
QQmlDebuggingEnabler.enableDebugging(True)
app = QApplication(sys.argv)
For instructions on how to use the QML debugger, see Debugging a Qt Quick Example Application.
Note
The code should be removed or disabled when shipping the application as it poses a security risk.
