Composite widget size problem

[Russell Shaw <rjshaw netspace net au>]

Hi all,

In a composite widget i'm making, this code gives an error:

  table->tree=gtk_label_new("HHHHHH");
  gtk_box_pack_start(GTK_BOX(table),table->tree,FALSE,FALSE,0);
  gtk_widget_show_all(GTK_WIDGET(table));

error:

  (db:3782): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate
                             widget with width 936 and height -18322


"table" is my own gobject, inheriting from GtkVBox.


Leaving out the above lines makes the error go away, and the rest of
the previous widget parts show ok, just by deleting:

  table->tree=gtk_label_new("HHHHHH");
  gtk_box_pack_start(GTK_BOX(table),table->tree,FALSE,FALSE,0);

I've looked for hours. Have i missed some size allocation procedure?
