This module provides an interface to the FORMS Library by Mark Overmars. The source for the library can be retrieved by anonymous ftp from host "ftp.cs.ruu.nl", directory SGI/FORMS. It was last tested with version 2.0b.
Most functions are literal translations of their C equivalents, dropping the initial "fl_" from their name. Constants used by the library are defined in module FL described below.
The creation of objects is a little different in Python than in C: instead of the `current form' maintained by the library to which new FORMS objects are added, all functions that add a FORMS object to a form are methods of the Python object representing the form. Consequently, there are no Python equivalents for the C functions fl_addto_form() and fl_end_form(), and the equivalent of fl_bgn_form() is called fl.make_form().
Watch out for the somewhat confusing terminology: FORMS uses the word object for the buttons, sliders etc. that you can place in a form. In Python, `object' means any value. The Python interface to FORMS introduces two new Python object types: form objects (representing an entire form) and FORMS objects (representing one button, slider etc.). Hopefully this isn't too confusing.
There are no `free objects' in the Python interface to FORMS, nor is there an easy way to add object classes written in Python. The FORMS interface to GL event handling is available, though, so you can mix FORMS with pure GL windows.
Please note: importing fl implies a call to the GL function foreground() and to the FORMS routine fl_init().
