GtkWidget::set_usize
void set_usize(int width, int height);
set_usize() sets a widget's
size in pixels. Sizing methods should only be called at one level of
the packing hierarchy; you may need to size either the container
or its children, but doing both will create conflicts in the size
requests made by child widgets internally, which in turn can lead
to unexpected results.
If you need either parameter to be ignored, use -1.

supplied by GtkBox and
GtkTable.
