Class OffsetRulerRenderer

java.lang.Object
  extended by org.biojava.utils.AbstractChangeable
      extended by org.biojava.bio.gui.sequence.OffsetRulerRenderer
All Implemented Interfaces:
SequenceRenderer, Changeable

public class OffsetRulerRenderer
extends AbstractChangeable
implements SequenceRenderer

OffsetRulerRenderer can render the ruler starting from an arbitrary offset from the sequence. For example if the Protein contained an N-Terminal His tag then coordinate 1 should correspond to the start of the protein, not the tag. This implementation borrows heavily from RulerRenderer

1.5

public OffsetRulerRenderer()
                    throws IllegalArgumentException
Throws:
IllegalArgumentException

Method Detail

setSequenceOffset

public void setSequenceOffset(int offset)
                       throws ChangeVetoException
Throws:
ChangeVetoException

getSequenceOffset

public int getSequenceOffset()

setTickDirection

public void setTickDirection(int dir)
                      throws ChangeVetoException
Throws:
ChangeVetoException

getTickDirection

public int getTickDirection()

getMinimumLeader

public double getMinimumLeader(SequenceRenderContext context)
Description copied from interface: SequenceRenderer
Retrieve the minimum leading distance for this renderer when rendering src.

The leading distance may vary between sequence panels - for example based upon sequence length.

Specified by:
getMinimumLeader in interface SequenceRenderer
Parameters:
context - the SequenceRenderContext to return info for
Returns:
the leading distance of the renderer for that sequence panel

getMinimumTrailer

public double getMinimumTrailer(SequenceRenderContext context)
Description copied from interface: SequenceRenderer
Retrieve the minimum trailing distance for this renderer when rendering src.

The trailing distance may vary between sequence panels - for example based upon sequence length.

Specified by:
getMinimumTrailer in interface SequenceRenderer
Parameters:
context - the SequenceRenderContext to return info for
Returns:
the trailing distance of the renderer for that sequence panel

getDepth

public double getDepth(SequenceRenderContext src)
Description copied from interface: SequenceRenderer
Retrieve the depth of this renderer when rendering src.

The depth may vary between sequence panels - for example based upon sequence length. Each line of information in the SequenceRendererContext only renders a region of the sequence. The depth for one complete line may be different from that for another due to the sequence having more or less information in that region to show. For example, a feature renderer implementation may chose to collapse down to a depth of zero pixels if there are no features to render within a region.

Specified by:
getDepth in interface SequenceRenderer
Parameters:
src - the SequenceRenderContext to return info for
Returns:
the depth of the renderer for that sequence panel

paint

public void paint(Graphics2D g2,
                  SequenceRenderContext context)
Description copied from interface: SequenceRenderer
Render a portion (possibly all) of the information for src to g, displaying all of the data that would fall within seqBox.

Specified by:
paint in interface SequenceRenderer
Parameters:
g2 - the Graphics2D to render to
context - the SequenceRenderContext that encapsulates the information to render

processMouseEvent

public SequenceViewerEvent processMouseEvent(SequenceRenderContext context,
                                             MouseEvent me,
                                             List path)
Description copied from interface: SequenceRenderer
Produce a SequenceViewerEvent in response to a mouse gesture.

A SequenceRenderer that performs any form of coordinate remapping should ensure that it appropriately transforms the mouse event. However, in the SequenceViewerEvent returned, the MouseEvent should be in untransformed coordinates.

The SequenceRenderer implementation should append itself to the path list before constructing the SequenceViewerEvent.

Specified by:
processMouseEvent in interface SequenceRenderer
Parameters:
context - the SequenceRenderContext currently in scope
me - a MouseEvent that caused this request
path - the List of SequenceRenderer instances passed through so far
Returns:
a SequenceViewerEvent encapsulating the mouse gesture
