Gumtree : SICS Device Status Gadget

Created by Tony Lam, last modified on Dec 09, 2009

Introduction

SICS device status gadget is a generic component for displaying dynamic components from the hipadabase tree. The layout of the gadget is follow:

icon (optional)	device label	current value	unit (optional)
icon (optional)	device label	current value	unit (optional)
...

Adding Device To Gadget

To add devices for status monitoring programmatically, try:

gadget.getDeviceURIList().add(&lt;URI&gt;)

This gadget is also designed to be run with dashboard, so devices can be set via single string:

// Use comma separated uri string
gadget.setDeviceURIs(&quot;sics://hdb/sample/phi, sics://hdb/sample/chi&quot;)

Icon Support

To enable icon support, you need to supply "DeviceStatusGadget.SHOW_ICON" to the style, and set ILabelProvider to the gadget.

Other Support Style

Unit support is enabled by supplying "DeviceStatusGadget.SHOW_UNIT" to the style. You can also add a separator in between by adding empyt URI, for example:

// Use comma separated uri string
gadget.setDeviceURIs(&quot;sics://hdb/sample/phi, , sics://hdb/sample/chi&quot;)

Above will add a separator between motors phi and chi.

Examples

Fixed Gadget

You can create a fixed gadget for monitoring a set of predefined devices by subclassing this status widget:

public class WombatMotorStatusGadget extends DeviceStatusGadget {

    public WombatMotorStatusGadget(Composite parent, int style) {
        super(parent, SHOW_UNIT);
        setDeviceURIs(&quot;sics://hdb/sample/phi, sics://hdb/sample/chi&quot;);
    }

}

To include icons:

import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Composite;
import org.gumtree.gumnix.sics.ui.widget.DeviceStatusGadget;

import au.gov.ansto.bragg.nbi.ui.internal.InternalImage;

public class ReactorSourceGadget extends DeviceStatusGadget {

    private static URI URI_POWER = URI.create(&quot;sics://hdb/instrument/source/power&quot;);

    private static URI URI_CNS_IN = URI.create(&quot;sics://hdb/instrument/source/cns_inlet_temp&quot;);

    private static URI URI_CNS_OUT = URI.create(&quot;sics://hdb/instrument/source/cns_outlet_temp&quot;);

    public ReactorSourceGadget(Composite parent, int style) {
        super(parent, SHOW_ICON | SHOW_UNIT);
        getDeviceURIList().add(URI_POWER);
        getDeviceURIList().add(URI_CNS_IN);
        getDeviceURIList().add(URI_CNS_OUT);
        setLabelProvider(new LabelProvider() {
            public Image getImage(Object element) {
                URI uri = (URI) element;
                if (uri.equals(URI_POWER)) {
                    return InternalImage.POWER_16.getImage();
                } else if (uri.equals(URI_CNS_IN)) {
                    return InternalImage.INLET_16.getImage();
                } else if (uri.equals(URI_CNS_OUT)) {
                    return InternalImage.OUTLET_16.getImage();
                }
                return null;
            }
            public String getText(Object element) {
                URI uri = (URI) element;
                if (uri.equals(URI_POWER)) {
                    return &quot;Power&quot;;
                } else if (uri.equals(URI_CNS_IN)) {
                    return &quot;CNS In&quot;;
                } else if (uri.equals(URI_CNS_OUT)) {
                    return &quot;CNS Out&quot;;
                }
                return &quot;&quot;;
            }
        });
    }

Dashboard

This gadget can be used as custom SWT component, or embedded into the dashboard:

&lt;dashboard title=&quot;Wombat Control&quot; layoutConstraints=&quot;flowx&quot;&gt;
  &lt;widget classname=&quot;org.gumtree.gumnix.sics.ui.widget.DeviceStatusGadget&quot; title=&quot;Status&quot; style=&quot;4&quot;&gt;
    &lt;parameters&gt;
      &lt;deviceURIs&gt;
        sics://hdb/sample/translate_x,
        sics://hdb/sample/rotate
      &lt;/deviceURIs&gt;
    &lt;/parameters&gt;
    &lt;/widget&gt;
