Instead of wrapping the searchbar for small screens (which looks ugly
and breaks the initial window size on large screens), hide the filter
combo box in views that would otherwise be too wide for the screen.
There's no loss of functionality when hiding the filter combo box.
It's just a set of convenient pre-defined searches, all of which can
be reproduced through the Advanced Search interface.
New functions:
e_shell_searchbar_get_filter_visible()
e_shell_searchbar_set_filter_visible()
EShellView now holds a reference to the active GalViewInstance. Where
applicable, the EShellView subclass is responsible for keeping this up
to date when the sidebar selection changes.
Holding a reference allows EShellView to implement common actions like
"Save Current View" directly instead pushing it on to subclasses.
New functions:
e_shell_view_get_view_instance
e_shell_view_set_view_instance
This fixes a bug in the old implementation where the application could
crash after a second shell window was created and destroyed, because a
signal handler with the destroyed shell window as the closure was left
connected.
But moreover this simplifies the implementation by using a property
binding plus transform function instead of juggling signal handlers,
and also adds code comments where things get a little tricky.
Removed (now unused) functions:
e_shell_window_get_toolbar_new_prefer_item
e_shell_window_set_toolbar_new_prefer_item
