Object types defined here: wp: a window dp: a drawing structure (only one can exist at a time) mp: a menu tp: a textedit block bp: a bitmap */ /* Rules for translating C stdwin function calls into Python stwin: - All names drop their initial letter 'w' - Functions with a window as first parameter are methods of window objects - There is no equivalent for wclose(); just delete the window object (all references to it!) (XXX maybe this is a bad idea) - w.begindrawing() returns a drawing object - There is no equivalent for wenddrawing(win); just delete the drawing object (all references to it!) (XXX maybe this is a bad idea) - Functions that may only be used inside wbegindrawing / wendddrawing are methods of the drawing object; this includes the text measurement functions (which however have doubles as module functions). - Methods of the drawing object drop an initial 'draw' from their name if they have it, e.g., wdrawline() --> d.line() - The obvious type conversions: int --> intobject; string --> stringobject - A text parameter followed by a length parameter is only a text (string) parameter in Python - A point or other pair of horizontal and vertical coordinates is always a pair of integers in Python - Two points forming a rectangle or endpoints of a line segment are a pair of points in Python - The arguments to d.elarc() are three points. - The functions wgetclip() and wsetclip() are translated into stdwin.getcutbuffer() and stdwin.setcutbuffer(); 'clip' is really a bad word for what these functions do (clipping has a different meaning in the drawing world), while cutbuffer is standard X jargon. XXX This must change again in the light of changes to stdwin! - For textedit, similar rules hold, but they are less strict.
