The See-Through interactor

> > > >

The IlvSeeThroughInteractor allows the user to temporarily see a part of a map independently from the current layer visibility states. This means that users can interactively reveal layers beneath a layer over which the mouse is pressed.

With this interactor, the user drags a square over the map, which displays the layers registered for this interactor. IlvSeeThroughConfigurationPanel is provided as a default configuration tool to interactively select layers in a Swing GUI.

IlvSeeThroughInteractor seeThrough = new IlvSeeThroughInteractor();
// configure the interactor
IlvSeeThroughConfigurationPanel panel = new
          IlvSeeThroughConfigurationPanel(manager, seeThrough);
JOptionPane pane = new JOptionPane();
pane.setMessage(panel);
JDialog dialog = pane.createDialog(view, title);
panel.update();
dialog.setVisible(true);
// attach to the view.
view.setInteractor(seeThrough);

To create this interactor and attach it to an IlvManagerView , use the following code:
