Method Detail

redraw

public void redraw()

Calls Component.repaint() in a thread-safe way. The component is re-drawn on the screen. This is especially useful for PictureComponent objects.

resizeTo

public void resizeTo(double width,
                     double height)

Resizes the component to the given dimensions

smoothResize

public void smoothResize(double width,
                         double height,
                         int milliseconds)

Smoothly resizes this component to the given dimensions over the time interval given.

moveTo

public void moveTo(double x,
                   double y)

Moves the component to the given coordinates

smoothMove

public void smoothMove(double x,
                       double y,
                       int milliseconds)

Smoothly moves this component to the given coordinates over the time interval given.

getWidth

public int getWidth()

Returns the width of the component

getHeight

public int getHeight()

Returns the height of the component

setFeedbackText

public void setFeedbackText(String text)

If possible, sets the text at the bottom of the window that this component is displayed in.
