Question

我在codeblocks运行时遇到麻烦。它说“（HelloWorld.exe：3312）：libglade-CRITICAL **：glade_xml_relative_file：断言 `filename！= NULL'失败“

我正在使用Glade和GTK为我的项目构建一个用户界面，但我已经工作了好几天，我仍然无法弄清楚出了什么问题？谢谢。

int main(int argc, char *argv[])
{
     gtk_init(&argc, &argv);

     /*import glade file*/
     xml = glade_xml_new("hello.glade", NULL, NULL);

     /* get a widget (useful if you want to change something) */
     widget = glade_xml_get_widget(xml, "mainWindow");

     /* connect signal handlers */
     glade_xml_signal_autoconnect(xml);

     /*show widget*/
     gtk_widget_show (widget);

     gtk_main();

     return 0;
}

它构建良好，当我尝试运行它时它不会运行。

林间空地文件基本上有两种格式：1:libglade，2:gtkBuilder。

我在夏季项目工作时也面临同样的问题。而不是使用glade_xml_new()使用gtk_builder_new()来构建您的glade文件，因为我认为您的glade文件是gtkBuilder类型。

示例程序：

 int main(int argc, char *argv[])
{
    GtkBuilder *gtkBuilder; 
    GtkWidget  *window;

    gtk_init(&argc, &argv);
    gtkBuilder = gtk_builder_new(); 

    gtk_builder_add_from_file(gtkBuilder, "name of your glade file", NULL);/*this api is used to                                                  
                               build the glade file which is created by using glade(glade3) UI designer.*/


    window = GTK_WIDGET( gtk_builder_get_object( gtkBuilder, "name of your window") );


    gtk_builder_connect_signals( gtkBuilder, NULL ); /*connecting signals so that appropriate   
                                       handler can be called to handle the button clicked event*/
    g_object_unref(G_OBJECT(gtkBuilder));
    gtk_widget_show(window);
    gtk_main(); /*it is basically a loop to make window appear. if we not write it then window                    
                 will appear but disappear after few seconds automatically.*/
    return 0;
}

示例程序不完整只是了解构建glade文件的正确方法完整的程序以及有关如何使用gtk库构建GUI的更多信息，您可以参考http://programming-simplified.blogspot.com
