public class RotateCommand

extends ApplyTransformationCommand

Rotate a GraphicalObject.

Here is an example of how to rotate (around the specified point) 1 radian on the Sheet: class MenuRotateRightListener implements ActionListener { public void actionPerformed(ActionEvent evt) { Point pt = new Point(cmdsubsys.getAbsoluteLastXLocation(), cmdsubsys.getAbsoluteLastYLocation()); cmdqueue.doCommand(new RotateCommand(TestSheet.this, 1, cmdsubsys.getAbsoluteLastXLocation(), cmdsubsys.getAbsoluteLastYLocation())); } // of actionPerformed } // inner class

Here is an example of how to rotate the selected objects (around the specified point) 1 radian: class MenuRotateSelObjRightListener implements ActionListener { public void actionPerformed(ActionEvent evt) { GraphicalObjectCollection gobs; GraphicalObject gob; Iterator it; gobs = cmdsubsys.getSelectedGraphicalObjects(); it = gobs.getForwardIterator(); while (it.hasNext()) { gob = (GraphicalObject) it.next(); cmdqueue.doCommand(new RotateCommand(gob, 1, cmdsubsys.getLocalLastXLocation(gob.getParentGroup()), cmdsubsys.getLocalLastYLocation(gob.getParentGroup()))); } } }

Constructor Detail

RotateCommand

public RotateCommand(GraphicalObject gob,
                     double theta)

Rotate around the center of the specified GraphicalObject.

RotateCommand

public RotateCommand(GraphicalObject gob,
                     double theta,
                     double x,
                     double y)

Rotate around the specified point in the specified GraphicalObject's relative coordinate space (ie gob's parent coordinate space).

Parameters:

gob - is the GraphicalObject to rotate.

theta - is the amount to rotate (in radians).

x - is the coordinate to rotate around, in relative coordinates (ie gob's parent's coordinate space).

y - is the coordinate to rotate around, in relative coordinates (ie gob's parent's coordinate space).
