Class ViewJFrameMemory

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.event.ChangeListener, javax.swing.RootPaneContainer, javax.swing.WindowConstants
    public class ViewJFrameMemory
extends javax.swing.JFrame
implements java.awt.event.ActionListener, javax.swing.event.ChangeListener
    Contains a seperatly running thread which checks the currently used and available memory. This frame will display that information several different ways:
    • in a text-area displaying memory used in K, total memory available to the JVM in K, and the relative used amount in per-cent.
    • in a bar-chart that resembles a graphic equaliser on a stereo.
    • in line-graph providing history information.

    The memory usage is sampled at a rate which is user-specified. The frame will allow the user to adjust how frequently the memory size will be sampled. For efficiency, no sampling will occur if the frame has been minimized.

    The memory frame provides direct user access to the function Runtime.getRuntime.gc() via a "Garbage Collector" button.

      • makeNumericsOnly

        protected void makeNumericsOnly​(javax.swing.JTextField txt)
        Takes a txt field, and forces the textfield to accept numbers, backspace and delete-key entries.

        also tells the pauseButton to click.

        This method should be checked periodically to see if there is a good way to ensure that the action within can be superceded by the functionality in MipavUtil.makeNumericsOnly().
