public class RubberRectPreserveAspect
extends ADragRubberband

Rubberband rectangle that preserves aspect ratio (square in screen space). Matches the old Rubberband Policy.RECTANGLE_PRESERVE_ASPECT behavior.

RubberRectPreserveAspect

public RubberRectPreserveAspect(Component component,
 IRubberbanded rubberbanded)

Method Details

modifyCurrentPoint

protected void modifyCurrentPoint(Point cp)

Description copied from class: ARubberband

Hook to modify the current point before using it. Default: clamp to component bounds (old Rubberband behavior).

Overrides:

modifyCurrentPoint in class ARubberband

draw

protected void draw(Graphics2D g)

Description copied from class: ARubberband

Draw the rubberband shape based on the current state. Called during dragging or when the toolbar requests a preview update. Subclasses must implement this to define the visual appearance of the rubberband.

Specified by:

draw in class ARubberband

Parameters:

g -

getRubberbandBounds

public Rectangle getRubberbandBounds()

Description copied from class: ARubberband

Get the bounding rectangle of the rubberband shape based on the current state. Used for area-based validity checks and as a default for vertex calculations. Subclasses should override this if their shape is not well-represented by a bounding rectangle (e.g. lines, polygons).

Specified by:

getRubberbandBounds in class ARubberband

Returns:

the bounding rectangle of the rubberband shape, or null if not applicable.
