私はtut.cという名前のCプログラムを作った：私は名前tut.gladeでプロジェクトを保存し、テキストエディタでファイルを開いた

、ここでのコードがあります：私はこのツールを作りました私はその後、コンパイル

#include <gtk/gtk.h> 

int 
main(int argc, 
     char **argv) 
{ 
    GtkBuilder *builder; 
    GtkWidget *window; 
    GError  *error = NULL; 

    /* Init GTK+ */ 
    gtk_init(&argc, &argv); 

    /* Create new GtkBuilder object */ 
    builder = gtk_builder_new(); 
    /* Load UI from file. If error occurs, report it and quit application. 
*  * Replace "tut.glade" with your saved project. */ 
    if(! gtk_builder_add_from_file(builder, "tut.glade", &error)) 
    { 
     g_warning("%s", error->message); 
     g_free(error); 
     return(1); 
    } 

    /* Get main window pointer from UI */ 
    window = GTK_WIDGET(gtk_builder_get_object(builder, "window1")); 

    /* Connect signals */ 
    gtk_builder_connect_signals(builder, NULL); 

    /* Destroy builder, since we don't need it anymore */ 
    g_object_unref(G_OBJECT(builder)); 

    /* Show window. All other widgets are automatically shown by GtkBuilder */ 
    gtk_widget_show(window); 

    /* Start main loop */ 
    gtk_main(); 

    return(0); 
} 

それは

を使用して次のコードを持っていますgcc -o tut tut.c $(pkg-config --cflags --libs gtk+-2.0 gmodule-2.0)

tutという実行可能ファイルがあります。私は

./tut

を使用してそれを実行し、私はこのエラーました：あなたは"window1"という名前のオブジェクトのために求めているが、そのようなものは、あなたのtut.gladeファイルではありません

(tut:19516): Gtk-CRITICAL **: gtk_widget_show: assertion `GTK_IS_WIDGET (widget)' failed 

Answer 1

を。唯一のウィンドウがXMLにあります：

<object class="GtkWindow" id="Home"> 

ので、この交換してみてください。これで

window = GTK_WIDGET(gtk_builder_get_object(builder, "window1")); 

：

window = GTK_WIDGET(gtk_builder_get_object(builder, "Home")); 

をそして多分window上のNULLチェックがあまりにも良いでしょう。
