Method Detail

canDraw

public boolean canDraw(GeneralProjector generalProjector)

Specified by:

canDraw in interface PanelOverlayDraw

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)

Specified by:

drawDataUnit in interface PanelOverlayDraw

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.

createKeyItem

public PamKeyItem createKeyItem(GeneralProjector generalProjector,
                       int keyType)

Description copied from interface: PanelOverlayDraw

provide a graphics component (probably a JPanel) that can be incorporated into a key panel for maps, and anything else that uses overlay graphics.

Since multiple keys may be created in various displays, new ones should normally be created each time this is called.

The GeneralProjector reference is passed as a parameter since the type of symbol or shape drawn on a particular plot may depend on the type of coordinate system. For example, whistles are drawn as a contour on the spectrogram display, but as a point (PamSymbol) on the map.

It is possible that some PanelOverlayDraw implementations will be rather complicated and the keys consequently quite large. The extendedKey parameter may therefore be used to draw a full or a cut down version of the key. It is expected that most implementations will ignore this parameter !

Specified by:

createKeyItem in interface PanelOverlayDraw

Parameters:

generalProjector - Reference to a GeneralProjector responsible for drawing with the PAnelOverlayDraw implementation

keyType - Draw a more complicated key, giving more detail

Returns:

java.awt compnent (usually a JPanel).

getHoverText

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

Description copied from interface: PanelOverlayDraw

Provides text for popup hover windows on displays.

Specified by:

getHoverText in interface PanelOverlayDraw

Parameters:

generalProjector - Projector associated with the display requiring the text

dataUnit - Data unit the mouse hovered over

Returns:

Text to display

hasOptionsDialog

public boolean hasOptionsDialog(GeneralProjector generalProjector)

Specified by:

hasOptionsDialog in interface PanelOverlayDraw

Parameters:

generalProjector - projector

Returns:

true if the drawing methods have options relevant to this projection which can be shown in a dialog of some sort (see showOptions)

showOptions

public boolean showOptions(java.awt.Window parentWindow,
                  GeneralProjector generalProjector)

Description copied from interface: PanelOverlayDraw

Show an options dialog for a particular projector.

Specified by:

showOptions in interface PanelOverlayDraw

Parameters:

parentWindow - parent window or frame

generalProjector - projector

Returns:
