* e-combo-cell-editable.* : new, GtkCellEditable for combo cells
* Makefile.am : build the new files
+2003-08-18 Ettore Perazzoli <ettore@ximian.com>
+
+ * e-source-selector.c (e_source_selector_selection_shown)
+ (e_source_selector_show_selection): Add precondition.
+
+2003-08-18 Ettore Perazzoli <ettore@ximian.com>
+
+ * test-source-selector.c (on_idle_create_widget): Add a
+ checkbutton to the test window for toggling the checkboxes on and
+ off. Also, put the list in a scrolled window and set a default
+ size for the main window.
+ (check_toggled_callback): Callback for the checkbutton.
+
+ * e-source-selector.c: New member checkboxes_shown in struct
+ ESourceSelectorPrivate.
+ (init): Set to TRUE.
+ (e_source_selector_show_selection): New.
+ (e_source_selector_selection_shown): New.
+ (toggle_cell_data_func): Don't show the toggle if checkboxes_shown
+ is FALSE.
+
+2003-08-17 Ettore Perazzoli <ettore@ximian.com>
+
+ * e-source-selector.c: New signal "primary_selection_changed",
+ removed members list_changed_callback_id and
+ selection_changed_callback_id in ESourceSelectorPrivate.
+ (rebuild_model): If the new set of selected sources is smaller
+ than the old one, emit "selection_changed".
+ (e_source_selector_peek_primary_selection): New.
+ (e_source_selector_set_primary_selection): New.
+ (selection_changed_callback): New callback for the "changed"
+ signal on our associated GtkTreeSelection.
+ (init): Connect.
+ (impl_dispose): Disconnect.
+ (setup_model): Use signal_connect_object() instead of saving the
+ ID.
+
+2003-08-15 Ettore Perazzoli <ettore@ximian.com>
+
+ * e-source-selector.c (cell_toggled_callback): Call
+ gtk_tree_model_row_changed() to let the model know that we changed
+ the data.
+
+2003-08-15 Ettore Perazzoli <ettore@ximian.com>
+
+ * test-source-selector.c: New test program.
