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".
