Thanks for your suggestion, unfortunately it wasn't a solution. I've
checked it in two following cases.

Number one, GtkTreeView doesn't exist in the Glade project, but there's
a GtkVBox with an empty row:


GladeXML *ui = glade_xml_new("menuui.glade", "window1", NULL);
GtkTreeIter iter;
GtkWidget *view = gtk_tree_view_new();
enum{
	KEYWORD_COL_KEYWORD=0,
	KEYWORD_COL_KEYWORD_ID,
	KEYWORD_NUM_COLS
};
GtkListStore *keywordList = gtk_list_store_new(KEYWORD_NUM_COLS,
					G_TYPE_STRING, G_TYPE_UINT);
gtk_list_store_append(keywordList, &iter);
gtk_list_store_set(keywordList, &iter,KEYWORD_COL_KEYWORD,"atest0",
		   KEYWORD_COL_KEYWORD_ID,(guint) 0,-1);
gtk_tree_view_set_model (GTK_TREE_VIEW (view),
			 GTK_TREE_MODEL(keywordList));
GtkWidget *vbox1 = glade_xml_get_widget(ui, "vbox1");
gtk_container_add (GTK_CONTAINER (vbox1), view);


Doesn't work. Instead of a GtkTreeView I've got nothing - the empty row
vanished and rest of the rows have stretched to fill whole container.

Number two, GtkTreeView has been created in Glade file.


GladeXML *ui = glade_xml_new("menuui.glade", "window1", NULL);
GtkWidget *view = glade_xml_get_widget(ui, "treeview1");
GtkTreeIter    iter;
enum{
	KEYWORD_COL_KEYWORD=0,
	KEYWORD_COL_KEYWORD_ID,
	KEYWORD_NUM_COLS
};
GtkListStore *keywordList = gtk_list_store_new(KEYWORD_NUM_COLS,
					G_TYPE_STRING, G_TYPE_UINT);
gtk_list_store_append(keywordList, &iter);
gtk_list_store_set(keywordList, &iter,KEYWORD_COL_KEYWORD,"atest0",
				KEYWORD_COL_KEYWORD_ID,(guint) 0,-1);
gtk_tree_view_set_model (GTK_TREE_VIEW (view),
			 GTK_TREE_MODEL(keywordList));


As a result, the treeview1 is an empty white space.

I hope I haven't snipped too much from the source. Have you got any
further ideas?

Jan Stępień
