Sorry Paul I am having a bit of jet lagged induced fun.
Here is an outline of a property ....
public class BoundryTypePropertyValue extends AbstractPropertyValue implements
PropertyValue {
public BoundryTypePropertyValue() {
// TODO Auto-generated constructor stub
}
@Override
public boolean isTrue( Object object, String value ) {
IWorkbench workbench = (IWorkbench) object;
BoundaryService service = (BoundaryService) workbench.getService(String.class);
String type = service.getStragey().getType();
return type.equals( value );
}
@Override
public boolean canCacheResult() {
return false;
}
@Override
public boolean isBlocking() {
return false;
}
}
Where you can smash that into udig.ui plugin.xml with something like:
<extension
id="net.refractions.udig.ui.properties"
name="uDig UI Properties"
point="net.refractions.udig.ui.objectProperty">
<object
targetClass="org.eclipse.ui.IWorkbench">
<property
class="net.refractions.udig.ui.internal.BoundryTypePropertyValue"
id="net.refractions.udig.ui.boundaryType">
</property>
</object>
</extension>
Before we get too excited we need to check with Jesse if the object property
thing can pass us in a workbench or not? If not we could ask it to pass us in
an IMap as a temporary measure.
Can you let me know if that works; if not I will try and teach the object
property stuff how to look up the current workbench.--
