Package: glade Version: 3.38.2-2 Severity: normal I know Debian can't do feature improvement. So this is more-or-less a public service memo for `<placeholder/>` to Glade users until future Glade fix this sloppy and not so well documented Glade behavior.
When things are too complicated to handle for Glade (such as relatively new feature supports), Glade sometimes give up creating the proper XML content for us and we need to use text editor to fix the sloppy XML to create the usable XML. One noticeable case is "Client side window decoration" area and another is the area created by "GtkPopoverMenu". If you try to add some graphic widget to the intended area using Glade GUI operation, Glade gives you "... need placeholder to add children" as a part of error message and refuse to do expected. Yes, this is sad. Please look at upstream issue page I updated with my workaround: https://gitlab.gnome.org/GNOME/glade/-/issues/499 I think the manual workaround I proposed there is non-trivial. Once you see the inside of the XML file with the text editor and compare this with recently published modern UI XML files out there, you understand `<placeholder/>` needs to be replaced with the manually crafted proper XML content. I hope this helps people to work around this sloppy Glade generated XML file issue. (At least, it took me a while to find my solution.)
