Definition Fl_Gl_Window.H:237
int can_do()
Returns non-zero if the hardware supports the current OpenGL mode.
Definition Fl_Gl_Window.H:133
static int can_do(int m)
Returns non-zero if the hardware supports the given OpenGL mode.
Definition Fl_Gl_Window.H:128
int mode(const int *a)
Set the OpenGL capabilites of the window using platform-specific data.
Definition Fl_Gl_Window.H:190
virtual Fl_Gl_Window * as_gl_window()
Returns an Fl_Gl_Window pointer if this widget is an Fl_Gl_Window.
Definition Fl_Gl_Window.H:223
void * context() const
Returns a pointer to the GLContext that this window is using.
Definition Fl_Gl_Window.H:193

Definition Fl_Gl_Window.H:246
static int can_do(const int *m)
Returns non-zero if the hardware supports the given OpenGL mode.
Definition Fl_Gl_Window.H:131
void context_valid(char v)
See char Fl_Gl_Window::context_valid() const.
Definition Fl_Gl_Window.H:125
Fl_Gl_Window(int W, int H, const char *l=0)
Creates a new Fl_Gl_Window widget using the given size, and label string.
