/* 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?
