iam adding items to the treeview in the startup of my application.
for (j=0;j<rec;j++) {
textNames[0] =buddies[j];
pixbuf = gdk_pixbuf_new_from_file("/usr/local/share/globe7/pixmaps/offline.bmp", &error);
gtk_list_store_append (store1, &iter);
gtk_list_store_set (store1, &iter,0,pixbuf,
1,textNames[0],
-1);
}
gtk_widget_show(treeview);
but My problem is items r not visble until we click on the treeview amd sometimes scrollbar also not visible.
y this problem occur and how can i fix this bug
thank u

Use gtk_widget_show_all (treeview). Also, you do not need to load a new version of the same pixbuf every single time. You can load one version and add it. You see, GdkPixbuf is not like widgets because it can be used multiple places. Every time you add it, its reference count will be incremented. Therefore, just create one version, add it to all rows, and then call gdk_pixbuf_unref() on it so that the object is destroyed when the tree view is destroyed.

Can you show more code around this such as how you create the tree view columns?

// creation of treeview
store1 = gtk_tree_store_new (2, GDK_TYPE_PIXBUF,G_TYPE_STRING);

GtkTreeViewColumn *col;

treeview = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store1));

gtk_tree_view_set_rules_hint(treeview,TRUE);
col = gtk_tree_view_column_new();
gtk_tree_view_column_set_title(col, "items");

renderer = gtk_cell_renderer_pixbuf_new();
gtk_tree_view_column_pack_start(col, renderer, FALSE);
gtk_tree_view_column_set_attributes(col, renderer,
"pixbuf", 0,
NULL);
renderer = gtk_cell_renderer_text_new();
gtk_tree_view_column_pack_start(col, renderer,FALSE);
gtk_tree_view_column_set_attributes(col, renderer,
"text", 1,
NULL);

g_object_set(renderer,"weight","PANG0_WEIGHT_BOLD","weight-set",TRUE,NULL);
gtk_tree_view_append_column(GTK_TREE_VIEW(treeview), col);
gtk_widget_show(treeeview);
//end
another problem is iam geeting space before pixbuf.
so i want to remove the space between pixbuf and thw wall of the treeview
thank u

Hello,

I have tried your code and make it working by replacing

gtk_list_store_append (store1, &iter);
gtk_list_store_set (store1, &iter,0,pixbuf,

by:

gtk_tree_store_append (store1, &iter, NULL);
gtk_tree_store_set (store1, &iter,0,pixbuf,
