I am using Quickly and Glade for the first time. I want to add certain widgets such as label and buttons on viewport via python code. Is it possible?
Yes, you can. If you haven't already loaded the glade file the load it with:
Replace "/path/to/file" with the path to the glade file. You can then get the container like the viewport:
Replace "nameOfViewport" with what you named it in glade. You can then add the widget using the view ports add() method:
Replace "nameOfWidget" with the name of the widget you want to add.
Edit: Make sure you initialize the widget with something like
for a label widget.
