Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.awt.Component

resizeThumb

public void resizeThumb(java.awt.Dimension size)

Notify this navigator panel of new size of enclosing container to possibly update the thumb nail (and porthole).

Parameters:

size - New size of container (will throw IllegalArgumentException if null.

setImage

public void setImage(java.awt.image.BufferedImage image)

Set new image in original size that is used to create a thumb nail image, which fits into this component. If passing a null argument, will remove the thumb nail image from this component.

Parameters:

image - BufferedIamge in original size that is

getImage

public java.awt.image.BufferedImage getImage()

setPorthole

public void setPorthole(java.awt.Rectangle hole)

Set porthole into this navigation window. The given rectangle describes the porthole in coordinates of the bigger view and thus must be translated into the coordinate system of this navigator panel before displaying it. If passing null as an argument, will remove the displayed porthole.

Parameters:

hole - Rectangle of porthole in original coordinates

paintComponent
