Member Function Documentation

void Flu_GL_Window::cartesianInput (  bool  b  )  [inline]

Setting this to true will report mouse input in cartesian coordinates instead of window coordinates. Default is true

bool Flu_GL_Window::is_context_valid (   )  [inline]

true if the OpenGL context managed by this window is valid to take OpenGL calls, false otherwise Note: This does not mean this context is the current one taking OpenGL calls, only that it *can* take calls when it becomes current.

void Flu_GL_Window::setAllInitFunc (  void(*  cb)(void *), void *  cbd = NULL )  [inline, static]

Set a function that will be called each time a new OpenGL context is created. This is useful for doing something globally specific for all contexts, such as loading OpenGL API entrypoints under Windows.

void Flu_GL_Window::setKeyboardFunc (  void(*  cb)(int, int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int key, int x, int y, void *user_data). key is which key generated the event, and x and y represent where in the OpenGL context the event ocurred.

void Flu_GL_Window::setMouseDownFunc (  void(*  cb)(int, int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int button, int x, int y, void *user_data). 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.

void Flu_GL_Window::setMouseDragFunc (  void(*  cb)(int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int x, int y, void *user_data). x and y represent where in the OpenGL context the event ocurred.

void Flu_GL_Window::setMouseMoveFunc (  void(*  cb)(int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature:(int x, int y, void *user_data). x and y represent where in the OpenGL context the event ocurred.

void Flu_GL_Window::setMouseUpFunc (  void(*  cb)(int, int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int button, int x, int y, void *user_data). 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.

void Flu_GL_Window::setMouseWheelFunc (  void(*  cb)(int, int, int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int dx, int dy, int x, int y). 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.

void Flu_GL_Window::setResizeFunc (  void(*  cb)(int, int, void *), void *  cbd = NULL )  [inline]

The passed function must have the following signature: (int width, int height, void *user_data). width and height represent the new size of the OpenGL context
