java.lang.Object

com.codename1.geoviz.FeaturePainter

public class FeaturePainter
extends java.lang.Object

A base class that encapsulates the painting for features of a GeoVizComponent. Subclasses can override how features are filled and stroked, then register themselves as the painter for a GeoVizComponent.

Method Detail

paint

public final void paint(com.codename1.ui.Graphics g,
                        Feature feature)

Paints the specified feature onto the given graphics context. This will call fill() and stroke() internally.

Parameters:

g - The graphics context to paint onto

feature - The feature to be painted.

fill

public final void fill(com.codename1.ui.Graphics g,
                       Feature feature)

Fills the specified feature on the graphics context

Parameters:

g -

feature -

stroke

public final void stroke(com.codename1.ui.Graphics g,
                         Feature feature)

Strokes the outline for a specified feature in the given graphics context.

Parameters:

g - The graphics context to stroke onto.

feature - The feature to be painted.

stroke

protected void stroke(com.codename1.ui.Graphics g,
                      Feature feature,
                      com.codename1.ui.geom.GeneralPath path)

Strokes the specified feature outline on the provided graphics context. This method also receives a GeneralPath object that has been pre-transformed using applied projections so that you can paint directly onto the graphics context using g.drawShape(). That said, it may simply be preferable to call super.stroke(g,feature,path) from the subclass after applying the desired settings using setColor(), etc...

Parameters:

g - The graphics context.

feature - The feature to be painted.

path - The precalculated path to stroke.

fill

protected void fill(com.codename1.ui.Graphics g,
                    Feature feature,
                    com.codename1.ui.geom.GeneralPath path)

Fills the specified feature on the provided graphics context. This method also receives a GeneralPath object that has been pre-transformed using applied projections so that you can paint directly onto the graphics context using g.drawShape(). That said, it may simply be preferable to call super.fill(g,feature,path) from the subclass after applying the desired settings using setColor(), etc...

Parameters:

g - The graphics context.

feature - The feature to be painted.

path - The precalculated path to stroke.
