Detailed Description

This most entertaining program was written in Tcl/Tk by Scott Hess (shess.nosp@m.@win.nosp@m.terne.nosp@m.t.co.nosp@m.m).

It's a clock that uses a bezier curve anchored at four points - the hour position, the minute position, the second position and the center of the clock - to show the time.

Mouse <Button-1> switches between display modes, and mouse <Button-2> switches between line thicknesses.

This program needs a tcl compiled with threads enabled, or alternatively, to replace Tkinter for mtTkinter.

getTime()

def _08b_clock_bezier.getTime

(

)

Returns the current time: hours, minutes and seconds.

Referenced by updateClock().

hands()

def _08b_clock_bezier.hands

(

aa

)

Calculate the set of points for the current hand type and
   the angles in the passed array.

Referenced by buildClock(), and setClock().

incrType()

def _08b_clock_bezier.incrType

(

e

)

Goes to the next clock type.

incrWidth()

def _08b_clock_bezier.incrWidth

(

e

)

Goes to the next clock width.

main()

def _08b_clock_bezier.main

(

)

Main program.

References buildClock(), stopClock(), and trigger().

setClock()

def _08b_clock_bezier.setClock	(		hour,
			minute,
			second
	)

Calculate the angles for the second, minute, and hour hands,
   and then update the clock hands to match.

(

)

Referenced by main().

trigger()

def _08b_clock_bezier.trigger

(

Creates a thread for the clock.

Creates a thread for the clock.

Referenced by main().

updateClock()

def _08b_clock_bezier.updateClock

(

)

Updates the hands of the clock each second.
