| 3 | /* Stdwin itself is a module, not a separate object type. |
| 4 | Object types defined here: |
| 5 | wp: a window |
| 6 | dp: a drawing structure (only one can exist at a time) |
| 7 | mp: a menu |
| 8 | tp: a textedit block |
| 9 | */ |
| 10 | |
| 11 | /* Rules for translating C stdwin function calls into Python stwin: |
| 12 | - All names drop their initial letter 'w' |
| 13 | - Functions with a window as first parameter are methods of window objects |
| 14 | - There is no equivalent for wclose(); just delete the window object |
| 15 | (all references to it!) (XXX maybe this is a bad idea) |
| 16 | - w.begindrawing() returns a drawing object |
| 17 | - There is no equivalent for wenddrawing(win); just delete the drawing |
| 18 | object (all references to it!) (XXX maybe this is a bad idea) |
| 19 | - Functions that may only be used inside wbegindrawing / wendddrawing |
| 20 | are methods of the drawing object; this includes the text measurement |
| 21 | functions (which however have doubles as module functions). |
| 22 | - Methods of the drawing object drop an initial 'draw' from their name |
| 23 | if they have it, e.g., wdrawline() --> d.line() |
| 24 | - The obvious type conversions: int --> intobject; string --> stringobject |
| 25 | - A text parameter followed by a length parameter is only a text (string) |
| 26 | parameter in Python |
| 27 | - A point or other pair of horizontal and vertical coordinates is always |
| 28 | a pair of integers in Python |
| 29 | - Two points forming a rectangle or endpoints of a line segment are a |
| 30 | pair of points in Python |
| 31 | - The arguments to d.elarc() are three points. |
| 32 | - The functions wgetclip() and wsetclip() are translated into |
| 33 | stdwin.getcutbuffer() and stdwin.setcutbuffer(); 'clip' is really |
| 34 | a bad word for what these functions do (clipping has a different |
| 35 | meaning in the drawing world), while cutbuffer is standard X jargon. |
| 36 | - For textedit, similar rules hold, but they are less strict. |
| 37 | XXX more? |
