Question

我根据所选gtkTreeView行中的单词创建了运行时创建的菜单。

gboolean
menu_RELEASE(GtkObject *object, GdkEvent *event, gpointer user_data)
{
    if (strlen(user_data) > 0)
    {
        gtk_entry_set_text(GTK_ENTRY(entry1), user_data);
        gtk_widget_grab_focus(entry1);
    }
    else
        main_art(get_sifra());

    return TRUE;
}

gboolean
treeview1_BUTTONRELEASE(GtkWidget *widget, GdkEventButton *event, gpointer *user_data)
{
    if (event->type == GDK_BUTTON_RELEASE && event->button == 3)
    {
        char *ntext;
        treesel = gtk_tree_view_get_selection(GTK_TREE_VIEW(view));
        if (gtk_tree_selection_get_selected(treesel, &model ,&iter))
        {
            gtk_tree_model_get(model, &iter, cNaziv, &ntext, -1);
            GtkWidget *menu, *menu_item;
            menu = gtk_menu_new();

            char *sresult = NULL;
            sresult = strtok(ntext, " ");
            while(sresult != NULL)
            {
                if (strlen(sresult)>1)
                {
                    menu_item = gtk_menu_item_new_with_label(sresult);
                    gtk_menu_shell_append(GTK_MENU_SHELL(menu), menu_item);
                    g_signal_connect(G_OBJECT(menu_item), "button-release-event", G_CALLBACK(menu_RELEASE), (gpointer)sresult);
                }
                sresult = strtok(NULL, " ");
            }

            menu_item = gtk_separator_menu_item_new();
            gtk_menu_shell_append(GTK_MENU_SHELL(menu), menu_item);
            //
            menu_item = gtk_image_menu_item_new_with_label("Uredi...");
            gtk_image_menu_item_set_image(GTK_IMAGE_MENU_ITEM(menu_item), GTK_WIDGET(gtk_image_new_from_stock(GTK_STOCK_EDIT, GTK_ICON_SIZE_MENU)));
            gtk_menu_shell_append(GTK_MENU_SHELL(menu), menu_item);
            g_signal_connect(G_OBJECT(menu_item), "button-release-event", G_CALLBACK(menu_RELEASE), (gpointer)"");
            //
            gtk_widget_show_all(menu);
            gtk_menu_popup(GTK_MENU(menu), NULL, NULL,  NULL, NULL, 0, gtk_get_current_event_time());
            return TRUE;
        }
    }
    return FALSE;
}

当菜单项被释放时，来自＆＃34; menu_RELEASE＆＃34;应该出现。但是发生了什么？菜单不会消失，保持可见和活跃状态。

我的代码出了什么问题？

你不应该连接到项目的鼠标按钮信号，这些信号太低了。您的处理程序“吞下”鼠标按钮信号，阻止GTK +处理它。

使用activate信号。

Gtk，运行时菜单
