Method Detail

setBoundingPoints2DRef

public void setBoundingPoints2DRef(Polygon2D p)

Description copied from interface: View

Set the reference for the bounding points for this view. Make sure that the bounds match what you are rendering. Otherwise, you will get some repaint errors, as well as selection errors.

Specified by:

setBoundingPoints2DRef in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Parameters:

p - is the polygon bounds. Assumes the bounds are already in local coordinates.

setAttachedGraphicalObject

public GraphicalObject setAttachedGraphicalObject(GraphicalObject newGob)

Description copied from interface: View

Used to set the GraphicalObject this View is attached to. All views attached will have the specified GOb set to this parameter. This method should be called automatically when the View is added to a GraphicalObject.

Specified by:

setAttachedGraphicalObject in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Parameters:

gob - is the GraphicalObject this View is attached to.

Returns:

a reference to gob.

setName

public String setName(String strName)

Description copied from interface: View

Set the name of this View.

Specified by:

setName in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Parameters:

strName - is the name of this View.

Returns:

a reference to strName.

setVisible

public void setVisible(boolean flag)

Description copied from interface: View

Set whether this view is visible or not.

Specified by:

setVisible in interface View

getBoundingPoints2DRef

public Polygon2D getBoundingPoints2DRef()

Description copied from interface: View

Get the reference for the bounding points for this view.

Specified by:

getBoundingPoints2DRef in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

the polygon bounds.

getAttachedGraphicalObject

public GraphicalObject getAttachedGraphicalObject()

Description copied from interface: View

Get the GraphicalObject this View is attached to.

Specified by:

getAttachedGraphicalObject in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

the GraphicalObject this View is attached to.

getName

public String getName()

Description copied from interface: View

Get the name of this View.

Specified by:

getName in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

Some useful not-too-technical real-world name for this View.

isVisible

public boolean isVisible()

Description copied from interface: View

Check whether this view is visible or not. A view is visible if the visible flag is set (via View.setVisible(boolean)) and if the view display value is greater than 0.

Specified by:

isVisible in interface View

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

true if the view is visible, false otherwise.

toString

public String toString()

Overrides:

toString in class Object

clone

public abstract Object clone()

Deep clone. You must override this method. So there.

Specified by:

clone in interface View

Overrides:

clone in class Object

clone

protected ViewImpl clone(ViewImpl v)

Make the passed view the same as us. For clone chaining purposes.
