People expect to be able to call gtk_widget_show_all on the dialog
to make action widgets visible, as seen e.g. in
https://bugzilla.gnome.org/show_bug.cgi?id=733431
To keep this working, we can't always set no-show-all on the
action_box. Only set it when the action_area is not used and empty.
With this, Ctrl-Q will close the window, and Ctrl-D will
toggle the dark theme. The accelerators are currently not
shown in the (manually constructed) menus.
The accel label in menus was getting a small allocation that
caused its draw code to always omit the accelerator string.
Fix that by setting halign to fill. To keep the menu label
left-aligned, set xalign to 0 to compensate.
Make gtk_widget_path_append_for_widget() add the state flags of the
widget, too.
This enables the ability to select pseudoclasses on all elements in a
selector.
Don't take a state when constructing the CSS matcher. Instead, rely on
the newly introduced state in the widget path.
This way, the state can be queried not only on the first element, but on
all elements of the widget path.
Set the widget path state flags with the state flags of the style
context.
We do not update the state flags but replace the previous one because we
want to be able to have save()/restore() unset state flags.
Make backdrop insensitive state more similar to the focused
windows one, mostly to make dark variant more usable and
focused -> backdrop transition less distracting.
Add left/right/top/bottom style classes according to which edge(s)
of the progressbar the progress is adjacent to. Only for a fraction
of 1.0 will we set more than one edge.
xdg-shell has moved on and replaced set_margin with set_window_geometry.
To properly support set_window_geometry requires a full rewrite of how
we've been dealing with toplevel windows for now, so just don't set any
margin until we can have a proper toplevel window abstraction in GTK+.
Don't shadow existing variables. Instead of sharing the allocation and
then overwriting the width/height when convenient, declare it in the
block we use it in, as, really, the three different paths are all
extremely different, and there's no sense in sharing the variable.
We can't avoid calling set_titlebar in buildable_add_child, since
GtkBuilder assumes that it can e.g. call grab_default at the end,
which only works if the widget is inside a toplevel at that point.
Instead, drop the titlebar and clean up priv->headerbar in constructed
if we find that we don't want a headerbar.
find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);
So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.
Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().
