GTK gossip: gtkstatusbar

The sequence column is usually located at the bottom of the sequence window, used to display some sequence information of the current sequence window operation sequence. The sequence column component in GTK is gtkstatusbar, you can use gtk_statusbar_new () to create a table. Each component or operation in the window can have a corresponding response message. In order to allow other components or operations in the column, use context in gtkstatusbar ID. You can use gtk_statusbar_get_context_id () and specify a region to obtain the corresponding context ID. For example: Gtkwidget * statusbar; Gint contextid; Statusbar = gtk_statusbar_new (); Contextid = Gtk_statusbar_get_context_id ( Gtk_statusbar (statusbar), "editor messages "); After obtaining the context ID, you can use the following functions to add or remove the Response Message to the gtkstatusbar: Guint gtk_statusbar_push (gtkstatusbar * statusbar, Guint context_id, Const gchar * text ); Void gtk_statusbar_pop (gtkstatusbar * statusbar, Guint context_id ); Void gtk_statusbar_remove (gtkstatusbar * statusbar, Guint context_id, Guint message_id ); The interest of the gtkstatusbar is stored in a stack. The method is later in and out. To add the interest, use gtk_statusbar_push (). A message_id. You can use the gtk_statusbar_remove () function to specify While gtk_statusbar_pop () is the top warning message in the heap response of the context ID. The following program uses Gtktoolbar Add Gtktextview With the gtkstatusbar, the external keys after the rows are more like a window program text handler: Gtk_statusbar_demo.c # Include <GTK/GTK. h> Void itempressed (gtkmenuitem * menuitem, gpointer data ){ G_print ("% s/n", data ); } Gtkwidget * createfilemenuitem (){ Gtkwidget * rootfileitem; Gtkwidget * filemenu; Gtkwidget * openmenuitem; Gtkwidget * savemenuitem; Gtkwidget * closemenuitem; Rootfileitem = gtk_menu_item_new_with_mnemonic ("_ file "); Filemenu = gtk_menu_new (); Openmenuitem = gtk_menu_item_new_with_label ("open "); Savemenuitem = gtk_menu_item_new_with_label ("save "); Closemenuitem = gtk_menu_item_new_with_label ("close "); Gtk_menu_shell_append (gtk_menu_shell (filemenu), openmenuitem ); Gtk_menu_shell_append (gtk_menu_shell (filemenu), savemenuitem ); Gtk_menu_shell_append (gtk_menu_shell (filemenu ), Gtk_separator_menu_item_new ()); Gtk_menu_shell_append (gtk_menu_shell (filemenu), closemenuitem ); Gtk_menu_item_set_submenu (gtk_menu_item (rootfileitem), filemenu ); G_signal_connect (gtk_object (openmenuitem), "Activate ", G_callback (itempressed), "open ...."); G_signal_connect (gtk_object (savemenuitem), "Activate ", G_callback (itempressed), "Save ...."); G_signal_connect (gtk_object (closemenuitem), "Activate ", G_callback (gtk_main_quit), null ); Return rootfileitem; } // Create a gtktoolitem that contains the subject, text, and picture.
