Refactor GtkFileChooserDialog sizing. 2007-05-18 Carlos Garnacho <carlos@imendio.com> Refactor GtkFileChooserDialog sizing. * gtkfilechooserembed.[ch] (delegate_get_resizable_hints) (_gtk_file_chooser_embed_get_resizable_hints): s/resizable_hints/resizable/, return just one boolean value to determine whether the filechooser should be resizable or not. * gtkfilechooserprivate.h (struct GtkFileChooserDialogPrivate): remove variables related to the GtkFileChooserEmbed get_default_size() and get_resizable() implementations. (struct GtkFileChooserDefault): Move default size management here. * gtkfilechooserdefault.c (gtk_file_chooser_default_size_allocate): Added, store currently allocated size to calculate default size later. (gtk_file_chooser_default_get_resizable_hints): s/resizable_hints/resizable/. (gtk_file_chooser_default_set_property): Reload settings if the file chooser action changes, this way the save expander state will be known before mapping the window, avoiding wrong window positioning and flickering. (#424299, #424309) (find_good_size_from_style): Only get size from style if it wasn't set previously. (gtk_file_chooser_default_get_default_size): return default size based on stored default size and preview/extra widget sizes. * gtkfilechooserdialog.c (file_chooser_widget_update_hints) (file_chooser_widget_realized_size_changed) (file_chooser_widget_unrealized_size_changed): simplified to (file_chooser_widget_size_changed): set window size and resizability based on the GtkFileChooserEmbed interface implementation. (Bug #420285, Tomeu Vizoso) (gtk_file_chooser_dialog_map): force a dialog size change, so it's clamped for sure to the 75% of the screen size. svn path=/trunk/; revision=17859
