GTK3 Porting Checklist
From Claws Mail FAQ
The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.
Does not work
- Foldersel dialog doesn't show alternating colors in the folder list.
- Fancy doesn't block remote content
- Vcalendar week/month views do not work, sometimes even crashes the whole program.
- "gtk-can-change-accels" has been removed: 'GtkSettings:gtk-can-change-accels has been deprecated since version 3.10 and should not be used in newly-written code. This setting is ignored.'
It seems that the only way to re-enable this is to switch to GtkApplication, and write our own acclerator implementation. https://developer.gnome.org/gtk3/stable/GtkApplication.html#gtk-application-add-accelerator
Works, but is ugly
- GtkSpinButton is too wide with the -/+ buttons being large and next to each other, instead of small and one above another like in GTK2.
Deprecated API
- GtkBox -> GtkGrid (for GTK4)
- GtkUIManager is deprecated in GTK3, to be removed in GTK4
