Constructor & Destructor Documentation

OpenGLWindow()

OpenGLWindow	(	int	x,
		int	y,
		int	w,
		int	h,
		const char *	l,
		glsDisplayFrame *	frame_
	)

Constructor for window

Parameters

x	Initial x loc of window
y	Initial y loc of window
w	Initial width of window
h	Initial height of window
l	Window title
frame_	Display to associate with window

Member Function Documentation

end()

void end

(

)

Overload of FLTK end() method. Used to signal FLTK to not make this the "current" window to add widgets to

GrabWindow()

void GrabWindow

(

char *

filename

)

Grabs the window contents and saves them to an uncompressed 24 bit BMP file

Parameters

filename

Name of the file to write a BMP to

handle()

int handle

(

int

)

Overload of FLTK event handle routine. This is how mouse and keyboard events get passed in.

Returns

0 if the event was not handled, otherwise non zero (usually 1).

make_current()

void make_current

(

)

Overload of FLTK make_current() method. Sets this window as the current OpenGL context

resizable()

void resizable

(

OpenGLWindow *

win

)

Overload of FLTK resizable() method.

Parameters

win	The widget to be used as the resizable region.

resize()

void resize	(	int	x,
		int	y,
		int	w,
		int	h
	)

Overload of FLTK resize() method. Resizes the window.

Parameters

x	New x coordinate of window on screen
y	New y coordinate of window on screen
w	New width of window in pixels
h	New height of window in pixels

show()

void show

(

)

Overload of FLTK show() method. Sets the visible flag for this window, causing it to be shown the next time the FLTK event loop is checked.

WindowToLogical()

void WindowToLogical	(	glsDisplayFrame *	frame,
		float	x,
		float	y,
		float &	lx,
		float &	ly
	)

Converts mouse window coordinates to logical simulation coordinates.

Parameters

frame	DisplayFrame to convert for
x	Mouse Device coordinate
y	Mouse Device coordinate
lx	Filled in with logical X coordinate
ly	Filled in with logical Y coordinate
