// Inline classes to provide portable support for threads and mutexes.
|
|
//
|
|
// FLTK does not use this (it has an internal mutex implementation
|
|
// that is used if Fl::lock() is called). This header file's only
|
|
// purpose is so we can write portable demo programs. It may be useful
|
|
// or an inspiration to people who want to try writing multithreaded
|
|
// programs themselves.
|
|
//
|
|
// FLTK has no multithreaded support unless the main thread calls Fl::lock().
|
|
// This main thread is the only thread allowed to call Fl::run() or Fl::wait().
|
|
// From then on FLTK will be locked except when the main thread is actually
|
|
// waiting for events from the user. Other threads must call Fl::lock() and
|
|
// Fl::unlock() to surround calls to FLTK (such as to change widgets or
|
|
// redraw them).
