Constructor Detail

ClackMarqueeHandler

public ClackMarqueeHandler(ClackFramework graphpad)

Constructor for GPMarqueeHandler.

Method Detail

getLastClick

public java.awt.Point getLastClick()

X-Y location of the last mouse click

We also pass non-popup events to the super-class and take care of updating the graph's selected cell

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent event)

getPortViewAt

public PortView getPortViewAt(int x,
                              int y,
                              boolean jump)

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent event)

mouseReleasedPopup

protected void mouseReleasedPopup(java.awt.event.MouseEvent event)

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent event)

overlay

public void overlay(java.awt.Graphics g)

paintPort
