GtkTreeView显示网格问题?

谢谢版主的热心帮助,我用gtk_tree_view_set_enable_tree_lines(GTK_TREE_VIEW(view), TRUE)及gtk_tree_view_set_grid_lines(GTK_TREE_VIEW(view), GTK_TREE_VIEW_GRID_LINES_BOTH)函数测试,还是不能显示,提示如下:
Gdk-CRITICAL **: gdk_gc_new: assertion `drawable != NULL' failed
Gdk-CRITICAL **: gdk_gc_copy: assertion `GDK_IS_GC (dst_gc)' failed
Gdk-CRITICAL **: gdk_gc_set_values: assertion `GDK_IS_GC (gc)' failed
Gdk-CRITICAL **: gdk_gc_set_dashes: assertion `GDK_IS_GC (gc)' failed

不知道这是什么原因?

有人做过这块吗?

GtkTreeView显示网格问题?

我测试代码如下:
#include <gtk/gtk.h>

enum
{
  COL_NAME = 0,
  COL_AGE,
  NUM_COLS
} ;

static GtkTreeModel *create_and_fill_model (void)
{
GtkListStore *store;
GtkTreeIter iter;
store = gtk_list_store_new (NUM_COLS, G_TYPE_STRING, G_TYPE_UINT);
/* Append a row and fill in some data */
gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter, COL_NAME, "Heinz El-Mann", COL_AGE, 51, -1);
/* append another row and fill in some data */
gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter, COL_NAME, "Jane Doe", COL_AGE, 23, -1);

gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter, COL_NAME, "Joe Bungop", COL_AGE, 91, -1);

return GTK_TREE_MODEL (store);
}

static GtkWidget *create_view_and_model (void)
{
GtkCellRenderer *renderer;
GtkTreeModel *model;
GtkWidget *view;
view = gtk_tree_view_new ();

gtk_tree_view_set_enable_tree_lines(GTK_TREE_VIEW(view), TRUE);
gtk_tree_view_set_grid_lines(GTK_TREE_VIEW(view), GTK_TREE_VIEW_GRID_LINES_BOTH);

/* --- Column #1 --- */
renderer = gtk_cell_renderer_text_new ();
gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view), -1, "Name", renderer, "text", COL_NAME, NULL);
/* --- Column #2 --- */
renderer = gtk_cell_renderer_text_new ();
gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view), -1, "Age", renderer, "text", COL_AGE, NULL);
model = create_and_fill_model ();
gtk_tree_view_set_model (GTK_TREE_VIEW (view), model);
/* The tree view has acquired its own reference to the
   * model, so we can drop ours. That way the model will
   * be freed automatically when the tree view is destroyed
   */
g_object_unref (model);

return view;
}

int main (int argc, char **argv)
{
GtkWidget *window;
GtkWidget *view;

gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (window, "delete_event", gtk_main_quit, NULL);
view = create_view_and_model ();
gtk_container_add (GTK_CONTAINER (window), view);
gtk_widget_show_all (window);
gtk_main ();

return 0;
}

GTK版本:2.10.6
