Class ImageView

java.lang.Object

org.lsst.ccs.gconsole.plugins.monitor.ImageView

All Implemented Interfaces:

MonitorView, AgentStatusListener

public class ImageView
extends Object
implements MonitorView

Image-based MonitorView.

The background image fills layer zero. Its size determines the preferred size of the view. Minimum and maximum sizes supplied determine minimum and maximum sizes of the panel. When the panel is resized, the background image is scaled.

The addImage(...), addComponent(...), addView(...) methods can be used to add extra images, components, and monitoring data views to other layers. The requirement that components in the same layer do not overlap adds an extra constraint to the minimum size of the panel. There are two versions of these methods, for images and components that should and should not scale when the page is resized.

All content should be added before the getPanel() method is called.
