Keep around a boolean state "is_empty" and update it when adding and
removing shells, and when the image of any shell changes. Do empty
display voodoo only when the "is_empty" state changes.
(gimp_image_window_image_notify): update the ui manager unconditionally
(both when a display is emptied *and* filled)
(gui_display_create): remove updating code here. It was not belonging
here anyway and the image window does the right thing now.
Add a GtkNotebook::switch_page() handler and move all shell switching
code there. In gimp_image_window_set_active_shell(), simply set the
right notebook page.
Which sets/unsets the title of an iconified toplevel image window to
the current progress message (if any). Use the new functions when the
window is (de)iconified. Not exactly the high art of programming, but
much better than the hacks in gimpdisplayshell-progress.c that are now
removed.
This API is most likely not final, but enables adding the vbox of
shell widgets to the image window's vbox *after* the shell constructor
returns. Seems to work nicely :-)
Move the last remaining function to the window. It doesn't actually
belong there, but it's better than the handler in the wrong place.
Added FIXME as reminder.
Don't set the window's active_display manually in gimp_display_shell_new(),
setting it properly after construction in gimp_display_new() works fine
now. Enable all disabled code in gimp_image_window_set_active_display().
Set the properties when updating title and status. In GimpImageWindow,
connect to notifications of the properties to update window title and
statusbar.
...which is connected to the window's active display. Remove updating
the window's menubar_manager from GimpDisplayShell's scaled()
impl. Had to hack around a bit with the new API to set the window's
active display because they are still the same widget.
And add gimp_image_window_set_active_display(). Call the new function
when creating a shell. Will all be done by the means of a GimpContext
later, but is a step to get rid of FIXME hacks.
Also move some of their related code and update other code to
go via gtk_widget_get_toplevel(), but also add some horrid temp
/* FIXME image window */ hacks.
