Member Function Documentation

virtual void Flu_GL_Canvas::keyboard (  int  key, int  x, int  y )  [inline, virtual]

Called when a key on the keyboard is pressed. key is which key generated the event, and x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::mouse_button_down (  int  button, int  x, int  y )  [inline, virtual]

Called when a mouse button is pressed. button is which mouse button generated the event: { FL_LEFT_MOUSE | FL_RIGHT_MOUSE | FL_MIDDLE_MOUSE }, and x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::mouse_button_up (  int  button, int  x, int  y )  [inline, virtual]

Called when a mouse button is released. button is which mouse button generated the event: { FL_LEFT_MOUSE | FL_RIGHT_MOUSE | FL_MIDDLE_MOUSE }, and x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::mouse_drag (  int  x, int  y )  [inline, virtual]

Called when the mouse is moved with a button pressed. x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::mouse_move (  int  x, int  y )  [inline, virtual]

Called when the mouse is moved without a button pressed. x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::mouse_wheel (  int  dx, int  dy, int  x, int  y )  [inline, virtual]

Called when the mouse scrolly wheel is scrolled. dx and dy represent the amount of movement of the mouse wheel (usually 1 or -1), and x and y represent where in the OpenGL context the event ocurred.

virtual void Flu_GL_Canvas::reshape (  int  width, int  height )  [inline, virtual]

Called when the canvas is resized. width and height represent the new size of the OpenGL context
