@Override
paintComponentback to summary
protected void paintComponent(Graphics g)

Overrides javax.swing.JComponent.paintComponent.

Doc from javax.swing.JComponent.paintComponent.

Calls the UI delegate's paint method, if the UI delegate is non-null. We pass the delegate a copy of the Graphics object to protect the rest of the paint code from irrevocable changes (for example, Graphics.translate).

If you override this in a subclass you should not make permanent changes to the passed in Graphics. For example, you should not alter the clip Rectangle or modify the transform. If you need to do these operations you may find it easier to create a new Graphics from the passed in Graphics and manipulate it. Further, if you do not invoke super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in an opaque color. If you do not honor the opaque property you will likely see visual artifacts.

The passed in Graphics object might have a transform other than the identify transform installed on it. In this case, you might get unexpected results if you cumulatively apply another transform.

Parameters
g:Graphics

the Graphics object to protect

Annotations
@Override
paintInSelectedback to summary
private void paintInSelected(Graphics g, int x, int y)

Parameters
g:Graphics

Graphics instance.

x:int

int. x axis value.

y:int

int. y axis value.

setSelectedback to summary
pack-priv void setSelected(int index)

Updates the line text for a given index. It is used when a byte is selected in hex pane.

Parameters
