public MapCommentOverlayGraphics(PamDataBlock parentDataBlock)

Method Detail

canDraw

public boolean canDraw(GeneralProjector projector)

Description copied from class: PamDetectionOverlayGraphics

Used to tell the various displays whether or not the data in the parentDataBlock can be drawn on each of those displays. This is based purely on the axis types of the displays and whether or not the parentDataBlock's data untits are likely to have data which can transform into those axis types.

For simplicity I've broken it up into the three main display types currently existing in Pamguard.

Specified by:

canDraw in interface PanelOverlayDraw

Overrides:

canDraw in class PamDetectionOverlayGraphics

Returns:

Returns whether or not the object can be drawn using the given projector. The implementation of CanDraw should examine the parameter types in GeneralProjector and check that it will know how to prvide those parameters before returning true, or false otherwise.

drawDataUnit

public java.awt.Rectangle drawDataUnit(java.awt.Graphics g,
                              PamDataUnit pamDataUnit,
                              GeneralProjector generalProjector)

Description copied from class: PamDetectionOverlayGraphics

Draw a PamDataUnit on a display.

This is split into separate routines for the three main display types for simplicity both of reading this code and for overriding the various functions.

If display types are added to PAMGUARD, these functions will need to be added to.

Specified by:

drawDataUnit in interface PanelOverlayDraw

Overrides:

drawDataUnit in class PamDetectionOverlayGraphics

Parameters:

g - Graphics handle to draw on

pamDataUnit - PamDataUnit to draw

generalProjector - Projector to use when drawing.

Returns:

A rectange surrouding whatever has just been drawn.

getHoverText

public java.lang.String getHoverText(GeneralProjector generalProjector,
                            PamDataUnit dataUnit,
                            int side)

Description copied from class: PamDetectionOverlayGraphics

Get tool tip content for the data unit for this projector.

Specified by:

getHoverText in interface PanelOverlayDraw

Overrides:

getHoverText in class PamDetectionOverlayGraphics

Parameters:

generalProjector - projector

dataUnit - dataunit

side - left or right (0 or 1 I think, might be -1 or +1 though !)

Returns:

tooltip content consisting of text and / or an image.
