Merged the federico-filename-entry branch, to fix bug #136541. Combined 2006-05-03 Federico Mena Quintero <federico@novell.com> Merged the federico-filename-entry branch, to fix bug #136541. Combined ChangeLogs: 2006-04-17 Federico Mena Quintero <federico@novell.com> * gtk/gtkfilechooserdefault.c (pending_select_paths_process): Oops, we *do* need to check that we are in OPEN mode before selecting the first row in the file list. See https://bugzilla.novell.com/show_bug.cgi?id=166906 (gtk_file_chooser_default_get_paths): If we are in the case for the file list, and the list has no selected rows, jump to the case for the filename entry. This is so that 1. The user types a filename in the SAVE filename entry ("foo.txt"). 2. He then double-clicks on a folder ("bar") in the file list. will yield the expected "bar/foo.txt" selection. 2006-03-29 Federico Mena Quintero <federico@novell.com> * gtk/gtkpathbar.c (gtk_path_bar_init): Reduce the inter-button spacing to 0. * gtk/gtkfilechooserdefault.c (browse_widgets_create): Make the location label bold. 2006-03-29 Federico Mena Quintero <federico@novell.com> * gtk/gtkfilechooserdefault.c (location_mode_set): Just change the location_mode field if we are in SAVE/CREATE_FOLDER modes. (gtk_file_chooser_default_get_paths): Get the path based on the currently focused widget, or the last-focused widget. This is what we should have been doing in the beginning, but it worked out fine because we didn't have the possibility of a filename entry in OPEN mode. (gtk_file_chooser_default_should_respond): Handle the case where the last focused widget is the location_entry. 2006-03-28 Federico Mena Quintero <federico@novell.com> * gtk/gtkfilechoosersettings.[ch]: New files with a simple framework for saving/loading settings from the file chooser in $XDG_CONFIG_HOME/gtk-2.0/gtkfilechooser. * gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_unmap): Save the current settings. (settings_save): New helper function. We save the location_mode and show_hidden flags. (gtk_file_chooser_default_map): Load the settings. (settings_load): New helper function. * gtk/gtkfilechooserentry.c (_gtk_file_chooser_entry_set_file_part): Oops, don't modify in_change. Our handlers are what set the file_part, so they *must* be run when we modify the text. 2006-03-27 Federico Mena Quintero <federico@novell.com> * gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault): Removed the save_file_name_entry. We'll make this be the same as the location_entry widget. (struct _GtkFileChooserDefault): Leave only location_button, location_entry_box, location_label, location_entry. We'll use a single toggle button for the location entry, which will appear below the path bar. (struct _GtkFileChooserDefault): Added a processing_pending_selections flag. * gtk/gtkfilechooserdefault.c (save_widgets_create): Destroy the old location_entry if necessary, and hide the location toggle widgets. (update_chooser_entry): In multiple selection mode, just clear the location_entry. (check_save_entry): Allow running in OPEN or SELECT_FOLDER modes if we are in LOCATION_MODE_FILENAME_ENTRY. (gtk_file_chooser_default_should_respond): Switch to a folder if the location_entry contains a folder name in OPEN and SAVE mode, not just SAVE mode. If the entry doesn't contain a folder name, but is otherwise well-formed, and we are in OPEN mode, return that we should respond with that filename. (gtk_file_chooser_default_initial_focus): Focus the location_entry if appropriate. (browse_widgets_create): Create the location_entry_box and the location_label here. (update_appearance): Call location_mode_set() when switching back to OPEN/SELECT_FOLDER mode. Hide the location_button when switching to SAVE/CREATE_FOLDER mode. (pending_select_paths_process): Turn the processing_pending_selections flag on and off around changes to the current selection. Don't special-case OPEN mode anymore, since the new flag will take care of things in update_chooser_entry(). (update_chooser_entry): Don't do anything if processing_pending_selections is TRUE. This keeps the entry from being polluted when changing folders. (location_popup_handler): In OPEN/SELECT_FOLDER modes, toggle between the path bar and the entry. In SAVE/CREATE_FOLDER modes, simply focus the location_entry. (update_from_entry): Removed. (location_entry_create): Removed. (open_location_cb): Removed. (file_list_build_popup_menu): Don't add an "Open _Location" menu item. (location_entry_set_initial_text): Don't do anything if current_folder is NULL. * gtk/gtkfilechooserentry.c (_gtk_file_chooser_entry_set_file_part): Turn in_change on and off around the call to gtk_entry_set_text(). This makes completion not happen when the caller has explicitly set a name. 2006-03-24 Federico Mena Quintero <federico@novell.com> * gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault): Added fields location_mode_box, location_pathbar_radio, location_filename_radio, location_widget_box, location_label, location_entry. The radio buttons will switch between the pathbar and the location entry; the other boxes are for layout purposes. (enum LocationMode): New enum. (struct _GtkFileChooserDefault): Added a location_mode field. * gtk/gtkfilechooserdefault.c (browse_widgets_create): Create the location radio buttons to switch between the pathbar and the location entry. Pack the browse_path_bar in the new location_widget_box instead of a generic hbox. (location_buttons_create): New function. (gtk_file_chooser_default_init): Initialize impl->location_mode. (location_switch_to_path_bar): New function. (location_switch_to_filename_entry): New function. * gtk/gtkfilechooserbutton.c (model_add_special): The display_name should not be const.

Fix #136077. 2004-04-01 Federico Mena Quintero <federico@ximian.com> Fix #136077. * gtk/gtkpathbar.h (struct _GtkPathBarClass): Add a "child_is_hidden" boolean argument to the "path-clicked" signal. * gtk/gtkpathbar.c (struct _ButtonData): Added a file_is_hidden field. (make_directory_button): Take a file_is_hidden argument; put it in the ButtonData. (_gtk_path_bar_set_path): See whether each path component path is a hidden file. (gtk_path_bar_class_init): Add the file_is_hidden argument to the "path-clicked" signal. (button_clicked_cb): See if the downwards button represents a hidden file for the file_is_hidden argument in the signal emission. * gtk/gtkmarshalers.list: Added a signal type VOID:POINTER,BOOLEAN. * gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_select_path): If we fail to switch folders, don't try to select the path in the file system model. Also, return the result from _gtk_file_system_model_path_do(). (gtk_file_chooser_default_select_path): Turn on show_hidden in the file system model if we are asked to select a hidden file. (path_bar_clicked): Show hidden files based on whether the immediate downwards folder in the path bar is a hidden file itself. (struct _GtkFileChooserDefault): Added fields browse_files_popup_menu and browse_files_popup_menu_hidden_files_item. (create_file_list): Set an object data key of "GtkFileChooserDefault" on the tree view so that we can find the impl from the popup menu callbacks. Also, hook up to the "button-press-event" and "popup-menu" signals in the file list to bring up a popup menu. (list_popup_menu_cb): New callback. (list_button_press_event_cb): New callback. Fix #138763: * gtk/gtkfilesystemmodel.c (_gtk_file_system_model_new): Oops, connect_object to "finished-loading".

Fix #136077. 2004-04-01 Federico Mena Quintero <federico@ximian.com> Fix #136077. * gtk/gtkpathbar.h (struct _GtkPathBarClass): Add a "child_is_hidden" boolean argument to the "path-clicked" signal. * gtk/gtkpathbar.c (struct _ButtonData): Added a file_is_hidden field. (make_directory_button): Take a file_is_hidden argument; put it in the ButtonData. (_gtk_path_bar_set_path): See whether each path component path is a hidden file. (gtk_path_bar_class_init): Add the file_is_hidden argument to the "path-clicked" signal. (button_clicked_cb): See if the downwards button represents a hidden file for the file_is_hidden argument in the signal emission. * gtk/gtkmarshalers.list: Added a signal type VOID:POINTER,BOOLEAN. * gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_select_path): If we fail to switch folders, don't try to select the path in the file system model. Also, return the result from _gtk_file_system_model_path_do(). (gtk_file_chooser_default_select_path): Turn on show_hidden in the file system model if we are asked to select a hidden file. (path_bar_clicked): Show hidden files based on whether the immediate downwards folder in the path bar is a hidden file itself. (struct _GtkFileChooserDefault): Added fields browse_files_popup_menu and browse_files_popup_menu_hidden_files_item. (create_file_list): Set an object data key of "GtkFileChooserDefault" on the tree view so that we can find the impl from the popup menu callbacks. Also, hook up to the "button-press-event" and "popup-menu" signals in the file list to bring up a popup menu. (list_popup_menu_cb): New callback. (list_button_press_event_cb): New callback. Fix #138763: * gtk/gtkfilesystemmodel.c (_gtk_file_system_model_new): Oops, connect_object to "finished-loading".
