这个实例是gtk与glade结合的例子，用glade布局界面，c程序实现treeview

glade布局图如下

treeview_glade.c源程序如下

#include <gtk/gtk.h>
#include <glade/glade.h>
#include <glade/glade-build.h>
#include <glib.h>

GladeXML *xml;

//创建treeview的数据model
GtkTreeModel*createModel(){
const gchar*files[]={"caterpillar.jpg","momor.jpg","hamimi.jpg","bush.jpg","caterpillar.jpg","momor.jpg","hamimi.jpg","bush.jpg"};
GdkPixbuf *pixbuf;
GtkTreeIter iter;
GtkListStore *store;
gint i;

store = gtk_list_store_new(1, G_TYPE_STRING);  //1列，数据类型为G_TYPE_STRING格式

for(i=0;i<8;i++){
  gtk_list_store_append(store,&iter);
  gtk_list_store_set(store,&iter,
      0,files[i],       //插入数据，0表示第0列，file[i]是数据名
         -1);
}//for

return GTK_TREE_MODEL(store);

}
//选择treeview的不同行，改变label的值
gbooleanselection_changed(GtkTreeSelection *selection, GtkLabel*label){
GtkTreeView *treeView;
GtkTreeModel *model;
GtkTreeIter iter;
gchar *active;

treeView =gtk_tree_selection_get_tree_view(selection);
model=gtk_tree_view_get_model(treeView);
gtk_tree_selection_get_selected(selection,&model,&iter);

gtk_tree_model_get(model,&iter,0,&active,-1);

gtk_label_set_text(label,active);

}

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

GtkWidget *window;
GtkWidget *treeView;
GtkCellRenderer *renderer;
GtkTreeViewColumn *column;
GtkWidget *label;
GtkTreeSelection *selection;

GtkWidget *scrollw;

gtk_init(&argc, &argv);

//window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
xml = glade_xml_new("test.glade",NULL,NULL); //从test.glade获得xml信息
window =glade_xml_get_widget (xml, "testWindow"); //window为主窗口
//glade_xml_signal_autoconnect(xml);
gtk_window_set_title(GTK_WINDOW(window),"GtkTreeView");
gtk_window_set_default_size(GTK_WINDOW(window),300,150);

scrollw = glade_xml_get_widget (xml,"scrolledwindow1");   //获得scrollewindow
treeView =gtk_tree_view_new_with_model(createModel());   //创建新的treeview,使用createModel()函数中创建的model
//treeView=glade_xml_get_widget (xml, "treeView1");
//gtk_tree_view_set_model(treeView,createModel());      //更该model,结果没有变化，还是一个空的treeview

renderer = gtk_cell_renderer_text_new();

column =gtk_tree_view_column_new_with_attributes("Filename",renderer,"text", 0, NULL); //插入列名“FileName”
gtk_tree_view_append_column(GTK_TREE_VIEW(treeView),column);

label=glade_xml_get_widget (xml, "label1");
gtk_label_set_text(label,"caterpillar.jpg");

gtk_container_add (GTK_CONTAINER (scrollw),treeView); //将treeview加入到scrollewoindow中去

selection =gtk_tree_view_get_selection(GTK_TREE_VIEW(treeView));
g_signal_connect(G_OBJECT(selection),"changed",G_CALLBACK(selection_changed),label);

g_signal_connect(GTK_OBJECT(window),"destroy",G_CALLBACK(gtk_main_quit),NULL);

gtk_widget_show_all(window);

gtk_main();
return 0;

}

运行结果如下所示：
