public class EditableOMScalingRaster
extends EditableOMGraphic

The EditableOMScalingRaster encompasses an OMScalingRaster, providing methods for modifying or creating it. This class only modifies OMScaling Rasters in lat/lon space (RENDERTYPE_LATLON). When you grab at the raster, you change the size of the entire rect. Grabbing the center point moves the raster. If there is an offset point, moving the center point changes the rect's position in relation to the offset point. Moving the offset point moves the rect, keeping the distance to the center point constant.

Constructor Detail

EditableOMScalingRaster

public EditableOMScalingRaster()
Create the EditableOMRect, setting the state machine to create the rect off of the gestures.


EditableOMScalingRaster

public EditableOMScalingRaster(GraphicAttributes ga)
Create an EditableOMScalingRaster with the rectType and renderType parameters in the GraphicAttributes object.


EditableOMScalingRaster

public EditableOMScalingRaster(OMScalingRaster omsr)
Create the EditableOMScalingRaster with an OMScalingRaster already defined, ready for editing.

Parameters:
omsr - OMScalingRaster that should be edited.
Method Detail

init

public void init()
Create and initialize the state machine that interprets the modifying gestures/commands, as well as initialize the grab points. Also allocates the grab point array needed by the EditableOMScalingRaster.


setGraphic

public void setGraphic(OMGraphic graphic)
Set the graphic within the state machine. If the graphic is null, then one shall be created, and located off screen until the gestures driving the state machine place it on the map.

Specified by:
setGraphic in class EditableOMGraphic
Parameters:
graphic - OMGraphic.

createGraphic

public void createGraphic(GraphicAttributes ga)
Create and set the graphic within the state machine. The GraphicAttributes describe the type of rect to create.

Specified by:
createGraphic in class EditableOMGraphic
Parameters:
ga - GraphicAttributes, describing the graphic to be created.

getGraphic

public OMGraphic getGraphic()
Get the OMGraphic being created/modified by the EditableOMScalingRaster.

Specified by:
getGraphic in class EditableOMGraphic

attachToMovingGrabPoint

public void attachToMovingGrabPoint(OffsetGrabPoint gp)
Attach to the Moving OffsetGrabPoint so if it moves, it will move this EditableOMGraphic with it. EditableOMGraphic version doesn't do anything, each subclass has to decide which of its OffsetGrabPoints should be attached to it.

Overrides:
attachToMovingGrabPoint in class EditableOMGraphic

detachFromMovingGrabPoint

public void detachFromMovingGrabPoint(OffsetGrabPoint gp)
Detach from a Moving OffsetGrabPoint. The EditableOMGraphic version doesn't do anything, each subclass should remove whatever GrabPoint it would have attached to an OffsetGrabPoint.

Overrides:
detachFromMovingGrabPoint in class EditableOMGraphic

initRectSize

public void initRectSize()

assertGrabPoints

public void assertGrabPoints()
Check to make sure the grab points are not null. If they are, allocate them, and them assign them to the array.


clearGrabPoints

protected void clearGrabPoints()

setGrabPoints

public void setGrabPoints(OMGraphic graphic)
Set the grab points for the graphic provided, setting them on the extents of the graphic. Called when you want to set the grab points off the location of the graphic.

Parameters:
icon -

setGrabPointsForOMSI

Specified by:
setGrabPoints in class EditableOMGraphic

move

public void move(java.awt.event.MouseEvent e)
Called to set the OffsetGrabPoint to the current mouse location, and update the OffsetGrabPoint with all the other GrabPoint locations, so everything can shift smoothly.

After that, redraw(e) should just be called, and the movingPoint will make the adjustments to the graphic that are needed.

Specified by:
move in class EditableOMGraphic

Specified by:
regenerate in class EditableOMGraphic

render

public void render(java.awt.Graphics graphics)
Draw the EditableOMScalingRaster parts into the java.awt.Graphics object. The grab points are only rendered if the rect machine state is RectSelectedState.RECT_SELECTED.
