void MENU_NODE::plot ( WINDOW  window  )  [inherited]

Initialise, then call plotx to do the real work.

This means that we can initialise plotting once only REGARDLESS of what menu subclass we start plotting.

e.g., we don't always start with a MENU_ROOT.

BOX & MENU_NODE::recalc_bounding_box ( INT16  tl_x,
INT16  tl_y 
) [protected, virtual, inherited]

SHOULD NEVER BE CALLED.

Compiler needs it as this can't be a pure virtual function as not all classes provide it and the compiler will not let you do "new" on a class which inherits a pure virtual function which it cannot resolve into a real function.

Reimplemented in NON_LEAF_MENU_NODE, and MENU_ROOT.

void DBL_VAR_MENU_LEAF::write_vars ( FILE *  fp,
BOOL8  changes_only

Save DOUBLE config vars to file, option on only changed vars

Reimplemented from MENU_NODE.
