FIProgressBar Class
The FIProgressBar Class implements a very lightweight progress Bar. It handles all the inputs
and outputs required by a Progress Bar component, including the minimum value, maximum value,
current value and other cosmetic properties.
This file is a pure ActionScript Object.
Component APIs:
setLimits(minValue, maxValue)
-----------------------------
setLimits helps to set the numerical maximum and minimum value for the progress bar to be plotted.
To plot a progress bar to show the loading of a movie - minValue would be 0 and maxValue would be
the total size of the flash movie.
setPosition(x,y)
----------------
Helps set the X and Y position of the progress bar. The x and y represents the top left position of
the bar.
setSize(width, height)
----------------------
Helps set the width and height of the progress bar.
setColors(Background Color, Border Color)
-----------------------------------------
Helps set the background and border color. All colors to be provided in hex code without #.
setBorderThickness()
--------------------
Helps set the border thickness
setValue(value)
---------------
This method sets and updates the current value of the progress bar. Use this method to update the
progress bar.
draw()
------
Draws the base of the progress bar. To be called once only after initialization.
