Interface LabelRenderer
- All Known Implementing Classes:
- LabelRenderer.RenderNothing, SimpleLabelRenderer
- public interface LabelRenderer
The interface for things that can render labels for a line of information
about a sequence.
Renderers are always activated within the context of a particular
SequenceRenderContext.
A single LabelRenderer can be shared among many sequence panels, or added
multiple times to the same panel. The renderer is required to request how
much leading and trailing space it requires, as well as the depth (space
orthogonal to the direction that the sequence is rendered).

RENDER_NOTHING
public static final LabelRenderer RENDER_NOTHING
paint
public void paint(java.awt.Graphics2D g,
SequenceRenderContext sp,
int min,
int max,
SequenceRenderContext.Border border)
- Render a label for the information for sp to g.
- Parameters:
g
- the Graphics2D to render tosp
- the SequencePanel that encapsulates the information to rendermin
- the minimum symbol to render (inclusive)max
- the maximum symbol to render (inclusive)
getMinimumWidth
public double getMinimumWidth(SequenceRenderContext sp)
- Retrieve the minimum space required to render the label.
- Parameters:
sp
- the SequencePanel to return info for
- Returns:
- the leading distance of the renderer for that sequence panel
