Method Detail

isEnabled

boolean isEnabled()

Returns whether this magic lens is enabled.

Returns:

whether this magic lens is enabled.

setEnabled

void setEnabled(boolean set)

Sets the enabled state of the magic lens.

Parameters:

set - the enabled state to set

getBounds

Rectangle2D getBounds()

Returns the bounds of the transformed coordinates. Coordintates outside these bounds are not transformed.

Returns:

the bounds of the transformed coordinates.

setLens

void setLens(float x,
             float y)

Sets for focus position

Parameters:

x - X coordinate of the position

y - X coordinate of the position

getLensX

float getLensX()

Returns the lens X center position.

Returns:

float

getLensY

float getLensY()

Returns the lens Y center position.

Returns:

float

setLensX

void setLensX(float x)

Sets the lensX.

Parameters:

x - The lest X to set

setLensY

void setLensY(float y)

Sets the lensY.

Parameters:

y - The lens Y to set

setLensRadius

void setLensRadius(float radius)

Sets the lens radius.

Parameters:

radius - the new radius.

getLensRadius

float getLensRadius()

Returns the lens radius.

Returns:

the lens radius.

addPropertyChangeListener

void addPropertyChangeListener(PropertyChangeListener l)

Add a PropertyChangeListener to the listener list. The listener is registered for all properties.

Parameters:

l - The PropertyChangeListener to be added

addPropertyChangeListener

void addPropertyChangeListener(String propertyName,
                               PropertyChangeListener listener)

Add a PropertyChangeListener for a specific property. The listener will be invoked only when a call on firePropertyChange names that specific property.

Parameters:

propertyName - The name of the property to listen on.

listener - The PropertyChangeListener to be added

removePropertyChangeListener

void removePropertyChangeListener(PropertyChangeListener l)

Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.

Parameters:

l - The PropertyChangeListener to be removed

removePropertyChangeListener

void removePropertyChangeListener(String propertyName,
                                  PropertyChangeListener listener)

Remove a PropertyChangeListener for a specific property.

Parameters:

propertyName - The name of the property that was listened on.

listener - The PropertyChangeListener to be removed
