539 | <h2>Python</h2> | |
540 | ||
541 | Python is an interpreted, interactive, object-oriented programming | |
542 | language often compared to Tcl, Perl, Scheme, or Java. | |
543 | ||
544 | <p> Python combines remarkable power with very clear syntax. It has | |
545 | modules, classes, exceptions, very high level dynamic data types, and | |
546 | dynamic typing. There are interfaces to many system calls and | |
547 | libraries, and new built-in modules are easily written in C or | |
548 | C++. Python is also usable as an extension language for applications | |
549 | that need a programmable interface. <p> | |
550 | ||
551 | <h2>wxWindows</h2> | |
552 | ||
553 | wxWindows is a free C++ framework designed to make cross-platform | |
554 | programming child's play. Well, almost. wxWindows 2 supports Windows | |
555 | 3.1/95/98/NT, Unix with GTK/Motif/Lesstif, with a Mac version | |
556 | underway. Other ports are under consideration. <p> | |
557 | ||
558 | wxWindows is a set of libraries that allows C++ applications to | |
559 | compile and run on several different types of computers, with minimal | |
560 | source code changes. There is one library per supported GUI (such as | |
561 | Motif, or Windows). As well as providing a common API (Application | |
562 | Programming Interface) for GUI functionality, it provides | |
563 | functionality for accessing some commonly-used operating system | |
564 | facilities, such as copying or deleting files. wxWindows is a | |
565 | 'framework' in the sense that it provides a lot of built-in | |
566 | functionality, which the application can use or replace as required, | |
567 | thus saving a great deal of coding effort. Basic data structures such | |
568 | as strings, linked lists and hash tables are also supported. | |
569 | ||
570 | <p> | |
571 | <h2>wxPython</h2> | |
572 | ||
573 | wxPython is a Python extension module that encapsulates the wxWindows | |
574 | GUI classes. Currently it is only available for the Win32 and GTK | |
575 | ports of wxWindows, but as soon as the other ports are brought up to | |
576 | the same level as Win32 and GTK, it should be fairly trivial to | |
577 | enable wxPython to be used with the new GUI. | |
578 | ||
579 | <p> | |
580 | ||
581 | The wxPython extension module attempts to mirror the class heiarchy | |
582 | of wxWindows as closely as possible. This means that there is a | |
583 | wxFrame class in wxPython that looks, smells, tastes and acts almost | |
584 | the same as the wxFrame class in the C++ version. Unfortunately, | |
585 | because of differences in the languages, wxPython doesn't match | |
586 | wxWindows exactly, but the differences should be easy to absorb | |
587 | because they are natural to Python. For example, some methods that | |
588 | return multiple values via argument pointers in C++ will return a | |
589 | tuple of values in Python. | |
590 | ||
591 | <p> | |
592 | ||
593 | There is still much to be done for wxPython, many classes still need | |
594 | to be mirrored. Also, wxWindows is still somewhat of a moving target | |
595 | so it is a bit of an effort just keeping wxPython up to date. On the | |
596 | other hand, there are enough of the core classes completed that | |
597 | useful applications can be written. | |
598 | ||
599 | <p> | |
600 | ||
601 | wxPython is close enough to the C++ version that the majority of | |
602 | the wxPython documentation is actually just notes attached to the C++ | |
603 | documents that describe the places where wxPython is different. There | |
604 | is also a series of sample programs included, and a series of | |
605 | documentation pages that assist the programmer in getting started | |
606 | with wxPython. | |
