Member Function Documentation

void Fl_Glut_Window::draw ( void ) [protected, virtual]

Draws the Fl_Gl_Window.

You must override the draw() method.

You must subclass Fl_Gl_Window and provide an implementation for draw(). You may also provide an implementation of draw_overlay() if you want to draw into the overlay planes. You can avoid reinitializing the viewport and lights and other things by checking valid() at the start of draw() and only doing the initialization if it is false.

The draw() method can only use OpenGL calls. Do not attempt to call X, any of the functions in <FL/fl_draw.H>, or glX directly. Do not call gl_start() or gl_finish().

If double-buffering is enabled in the window, the back and front buffers are swapped after this function is completed.

Reimplemented from Fl_Gl_Window.

void Fl_Glut_Window::draw_overlay ( ) [protected, virtual]

Reimplemented from Fl_Gl_Window.

int Fl_Glut_Window::handle ( int event ) [protected, virtual]

Handle some FLTK events as needed.

Reimplemented from Fl_Gl_Window.

void Fl_Glut_Window::make_current ( )

Sets things up so that the drawing functions in <FL/fl_draw.H> will go into this window. This is useful for incremental update of windows, such as in an idle callback, which will make your program behave much better if it draws a slow graphic. Danger: incremental update is very hard to debug and maintain!

This method only works for the Fl_Window and Fl_Gl_Window derived classes.

make all drawing go into this window (called by subclass flush() impl.)

Reimplemented from Fl_Gl_Window.
