RadArcItem

public RadArcItem(Layer layer,
 Point2D.Double wpc,
 Point2D.Double wp1,
 double arcAngle)

Method Details

updateFocus

protected void updateFocus()

Description copied from class: AItem

Hook called when geometry changes and the focus should be recomputed. The default implementation is a no-op.

Overrides:

updateFocus in class PathBasedItem

reshape

protected void reshape()

Description copied from class: PolygonItem

Reshape the polygon based on the modification. Not much we can do to a polygon except move the selected point. Keep in mind that if control or shift was pressed, the polygon will scale rather than coming here.

Overrides:

reshape in class PolygonItem

getSelectionPoints

public Point[] getSelectionPoints(IContainer container)

Description copied from class: AItem

Return the selection handles for this item in screen coordinates.

The default uses the vertices of AItem._lastDrawnPolygon if available, otherwise the four corners of AItem.getBounds(edu.cnu.mdi.container.IContainer).

Overrides:

getSelectionPoints in class AItem

Parameters:

container - the container rendering this item

Returns:

array of handle points, or null if bounds are unavailable

getRotatePoint

public Point getRotatePoint(IContainer container)

Description copied from class: PathBasedItem

Get the rotation point

Overrides:

getRotatePoint in class PathBasedItem

Parameters:

container - the container bing rendered

Returns:

the rotation point where rotations are initiated
