Use GtkBuilder to construct the Properties window
The Properties dialog is an fundamental feature of Files. It exposes information that wouldn't fit in the main views and allows to edit some attributes and permissions. Secondarily, it acts as an extension point.
Despite that, its design is showing its age. It doesn't make use of modern design patterns nor applies the layout best practices from the HIG.
The Properties dialog's UI is 100% constructed from the C source code in
src/nautilus-properties-window.c, intertwined with business logic. This makes it very cumbersome to modify the UI and, therefore, to apply design improvements.
Quoting from https://developer.gnome.org/gtk3/stable/ch01s03.html
GTK+ supports the separation of user interface layout from your business logic, by using UI descriptions in an XML format that can be parsed by the GtkBuilder class.
Scope and constraints
The porting to GtkBuilder UI definitions can be done by parts, or all at once.
Major UI redesign is not in scope of this issue, since we don't have mockups yet.
Minor UI design changes (such as paddings, alignments, etc.) are okay, particularly if they improve compliance with the HIG.
Extensions can provide custom tabs in Properties that we are still going to add programmatically. See
We also need to keep in mind that we may change how these extension tabs are created: !248
