- /* Stdwin module */
-
- /* Stdwin itself is a module, not a separate object type.
- 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.
- XXX more?
