C# Class BrightIdeasSoftware.MappedImageRenderer

This class maps a data value to an image that should be drawn for that value.

It is useful for drawing data that is represented as an enum or boolean.

Inheritance: BaseRenderer

Public Methods

Method	Description
Add ( Object value, Object image ) : void	Register the image that should be drawn when our Aspect has the data value.
Boolean ( Object trueImage, Object falseImage ) : MappedImageRenderer	Return a renderer that draw boolean values using the given images
MappedImageRenderer ( ) : System	Make a new empty renderer
MappedImageRenderer ( Object keysAndImages ) : System	Build a renderer from the given array of keys and their matching images
MappedImageRenderer ( Object key, Object image ) : System	Make a new renderer that will show the given image when the given key is the aspect value
MappedImageRenderer ( Object key1, Object image1, Object key2, Object image2 ) : System	Make a new renderer that will show the given images when it receives the given keys
Render ( Graphics g, Rectangle r ) : void	Render our value
TriState ( Object trueImage, Object falseImage, Object nullImage ) : MappedImageRenderer	Return a renderer that draw tristate boolean values using the given images

Method	Description
RenderCollection ( Graphics g, Rectangle r, ICollection imageSelectors ) : void	Draw a collection of images
RenderOne ( Graphics g, Rectangle r, Object selector ) : void	Draw one image

public Add ( Object value, Object image ) : void
value	Object	Value that the Aspect must match
image	Object	An ImageSelector -- an int, string or image
return	void

Make a new empty renderer

public MappedImageRenderer ( ) : System
return	System

Build a renderer from the given array of keys and their matching images

public MappedImageRenderer ( Object keysAndImages ) : System
keysAndImages	Object	An array of key/image pairs
return	System

Make a new renderer that will show the given image when the given key is the aspect value

public MappedImageRenderer ( Object key, Object image ) : System
key	Object	The data value to be matched
image	Object	The image to be shown when the key is matched
