Constructor Detail

ElementWrapper

public ElementWrapper(Element dc,
                      double x,
                      double y)

Method Detail

getHeight

public double getHeight()

Returns the height of the element wrapper.

setHeight

public void setHeight(double height)

Sets the height of the element wrapper. Notifies observers.

Parameters:

height - The new height

getWidth

public double getWidth()

Returns the width of the element wrapper.

setWidth

public void setWidth(double width)

Sets the width of the element wrapper. Notifies observers.

Parameters:

width - The new width

getX

public double getX()

Returns the x coordinate.

setX

public void setX(double x)

Sets the x coordinate. Notifies observers.

Parameters:

x - New x coordinate

getY

public double getY()

Returns the y coordinate.

setY

public void setY(double y)

Sets the y coordinate. Notifies observers.

Parameters:

y - New y coordinate

setXY

public void setXY(double x,
                  double y)

Sets the location of the element wrapper. Notifies observers. Using this method is recommended over calls to setX and setY if you need to set both coordinates.

Parameters:

x - New x coordinate

y - New y coordinate

setSize

public void setSize(double width,
                    double height)

Sets the size of the element wrapper. Notifies observers. Using this method is recommended over calls to setWidth and setHeight if you need to set both values.

Parameters:

width - New width

height - New height

getCenterX

public double getCenterX()

Returns the x coordinate of the center of the element wrapper.

getCenterY

public double getCenterY()

Returns the y coordinate of the center of the element wrapper.

moveXY

public void moveXY(double changeX,
                   double changeY,
                   Selection selection)

Moves the element wrapper and the connected connection wrappers. Notifies the observers.

Specified by:

moveXY in class DiagramComponentWrapper

Parameters:

changeX - the value to add to the x coordinate

changeY - the value to add to the y coordinate

selection - all the moved DiagramComponents
