Method Details

getBounds

public Rectangle2D getBounds(JComponent source,
 JComponent relativeTo,
 Rectangle2D rect)

Description copied from interface: DesignableDelegate

Fetch the current bounds of the given item, relative to the supplied JComponent. If the rect argument is null, a new Rectangle should be instantiated and returned. Otherwise, rect should be modified and returned to avoid unnecessary Rectangle instantiation, because this function is called very frequently.

Specified by:

getBounds in interface DesignableDelegate

initRect

protected Rectangle2D initRect(Rectangle2D rv,
 Rectangle2D copyFrom)

Initializes a return value rectangle rv, or creates a new one if it's null. If copyFrom isn't null, then the rect is set to that size.

getShapeBounds

public Shape getShapeBounds(JComponent item,
 JComponent relativeTo,
 Rectangle rect)

Description copied from interface: DesignableDelegate

Return non-rectangular bounds of the given item relative to the supplied JComponent. If the bounds happen to be rectangular, you may alter the supplied rectangle to avoid instantiating a new shape.

Specified by:

getShapeBounds in interface DesignableDelegate

getOffsettingParent

public JComponent getOffsettingParent(JComponent source)

Find the parent component for whose bounds the component is relative to.

Specified by:

getOffsettingParent in interface DesignableDelegate

convertRect

protected Rectangle2D convertRect(JComponent source,
 JComponent relativeTo,
 Rectangle2D r)

Converts a rectangle from the coordinates of one component to another.

convertShape

protected Shape convertShape(JComponent source,
 JComponent relativeTo,
 Shape shape)

getRotationAnchor

public Point2D getRotationAnchor(JComponent c)

Implemented using a client property with key "rotation.center" whose value is expected to be a Point2D.Float

Specified by:

getRotationAnchor in interface DesignableDelegate

setRotationAnchor

public void setRotationAnchor(JComponent object,
 Point2D point)

Puts the given point on the JComponent using client property "rotation.center"

Specified by:

setRotationAnchor in interface DesignableDelegate

getName

public String getName(JComponent object)

Uses the JComponent's name

Specified by:

getName in interface DesignableDelegate

findChildren

public Iterator<? extends JComponent> findChildren(JComponent container)

Description copied from interface: DesignableDelegate

Returns an iterator that iterates through the children of the given container in decreasing Z-order (highest layer to lowest layer)

Specified by:

findChildren in interface DesignableDelegate

getChildCount

public int getChildCount(JComponent container)

Description copied from interface: DesignableDelegate

Returns the count of the number of items currently held in the given container

Specified by:

getChildCount in interface DesignableDelegate
