get_preferred_height_vfunc for Gtk::CellRenderer seems to have no effect on 3.14 to the mailing list gtkmm-list

[Gaute Hope <eg gaute vetsj com>]

Hi list,

after upgrading gtkmm and gtk to 3.14 (from 3.12 on Arch Linux) my
custom CellRenderer is no longer able to set the height of its cell. I
have only this column.

I overload the get_preferred_height_vfunc according to the reference [0] by
doing:

     virtual void get_preferred_height_vfunc (
         Gtk::Widget& widget,
         int& minimum_height,
         int& natural_height) const override;

no matter what values I set minimum_height or natural_height to the rows
in the treeview (liststore) have the same (too narrow) height. Is there
some other way I should be doing this or is this a bug [1]?

The full code for the cell renderer can be found here:

- https://github.com/gauteh/astroid/blob/master/src/modes/thread_index_list_cell_renderer.cc

while the treeview can be found here:

Cheers, Gaute
