| 27 /* Stdwin itself is a module, not a separate object type. | |
| 28 Object types defined here: | |
| 29 wp: a window | |
| 30 dp: a drawing structure (only one can exist at a time) | |
| 31 mp: a menu | |
| 32 tp: a textedit block | |
| 33 */ | |
| 34 | |
| 35 /* Rules for translating C stdwin function calls into Python stwin: | |
| 36 - All names drop their initial letter 'w' | |
| 37 - Functions with a window as first parameter are methods of window objects | |
| 38 - There is no equivalent for wclose(); just delete the window object | |
| 39 (all references to it!) (XXX maybe this is a bad idea) | |
| 40 - w.begindrawing() returns a drawing object | |
| 41 - There is no equivalent for wenddrawing(win); just delete the drawing | |
| 42 object (all references to it!) (XXX maybe this is a bad idea) | |
| 43 - Functions that may only be used inside wbegindrawing / wendddrawing | |
| 44 are methods of the drawing object; this includes the text measurement | |
| 45 functions (which however have doubles as module functions). | |
| 46 - Methods of the drawing object drop an initial 'draw' from their name | |
| 47 if they have it, e.g., wdrawline() --> d.line() | |
| 48 - The obvious type conversions: int --> intobject; string --> stringobject | |
| 49 - A text parameter followed by a length parameter is only a text (string) | |
| 50 parameter in Python | |
| 51 - A point or other pair of horizontal and vertical coordinates is always | |
| 52 a pair of integers in Python | |
| 53 - Two points forming a rectangle or endpoints of a line segment are a | |
| 54 pair of points in Python | |
| 55 - The arguments to d.elarc() are three points. | |
| 56 - The functions wgetclip() and wsetclip() are translated into | |
| 57 stdwin.getcutbuffer() and stdwin.setcutbuffer(); 'clip' is really | |
| 58 a bad word for what these functions do (clipping has a different | |
| 59 meaning in the drawing world), while cutbuffer is standard X jargon. | |
|

Change set/getcutbuffer to use the new stdwin interface.
