This was ruined, with only 1 of the 8 subwindows rendering any content.
This commit fixes the responsible errors in the embedded GtkBuilder UIs:
• Fix broken replace by commit fb3d9022ad
of HBox with a Box having a broken orientation <property>
• Replace VBox and [HV]Paned with GtkOrientable successors (properly!)
• Remove use of Button:use_action_appearance, as this no longer exists
This commit also adds error reporting, in case other errors creep into
the GtkBuilder UI definitions, plus cleanup for the Builders and Windows
Also like the GtkExpander, the label widget is allocated the minimum
height for its allocated width and the remaining space is given to
the child, test case included.
Now the expander requests and distributes space naturally,
the expander widget prioritizes the child widget vertically
and only allocates the minimum height for width to the label
widget.
This commit makes a few massive changes to the extended layout
code:
a.) gtkextendedlayout.c --> gtksizerequest.c
b.) _is_height_for_width --> get_request_mode()
c.) get_desired_size(), get_desired_width(), get_desired_height() -->
get_size(), get_width(), get_height()
This is the first partial commit and only effects portions
of the tree that have already been merged in master (in order to
easily cherry pick this commit).
