Qt Designer - Generate only one .ui file with several widgets

I started using Qt Designer a few weeks ago to generate some custom widgets for my PySide application. There is something I wish I could do, but I cannot manage to find how: I would like to save all my widgets in only one big .ui, then compile them to only one big .py file so that all the GUI details are in the same file, say gui.py. That would allow me to write things like this:

import gui.MainWindow
import gui.FluffyRabbitWidget

class MainWindow(gui.MainWindow): pass
class FluffyRabbitWidget(gui.FluffyRabbitWidget): pass

Then I would not have to bother having a whole bunch of different files with Python code that I will never read since it is generated. So, how could I manage to have just one big .ui file? And if not feasable, would there be a way to tell pyside-uic to generate only one .py file with several .ui files as input?

Solution

  • Reading the source code of pyside-uic, you can see that it doesn't accept more than one .ui argument:

    opts, args = parser.parse_args()

if len(args) != 1:

    sys.stderr.write("Error: one input ui-file must be specified\n")

    sys.exit(1)

sys.exit(invoke(Driver(opts, args[0])))

    So the answer is: no. pyside-uic can't do this.

    A dirty solution might be to cat the generated files together, but this must be done every time you modify the widgets:

    $ cat generated_*.py > gui.py

    (Where generated_*.py should be a regex that matches the files generated for your widgets.
