I'm going through the outline view filtering example from the Xtext
documentation.
Regarding the example FilterFooAction class (see below):
- where does the "Activator" come from in the lines
setImageDescriptor(Activator.getImageDescriptor("icons/foo.gif "));
setDisabledImageDescriptor(Activator.getImageDescriptor("icons/foo.gif "));
?
I can't find any Activator class with the getImageDescriptor method in my
workspace.
There is an Activator org.eclipse.xtext.ui.core.internal.Activator
with an imageDescriptorFromPlugin method. I guess this should this be used
instead?
I'm using the 0.7.0.v200906222230 version of Xtext.
------------------------------------------------------------ -----------
public class FilterFooAction extends AbstractFilterAction {
public FilterFooAction(XtextContentOutlinePage outlinePage) {
super("Filter Foo", outlinePage);
setToolTipText("Show / hide foo");
setDescription("Show / hide foo");
setImageDescriptor(Activator.getImageDescriptor("icons/foo.gif "));
setDisabledImageDescriptor(Activator.getImageDescriptor("icons/foo.gif "));
}
@Override
protected String getToggleId() {
return "FilterFooAction.isChecked";
}
@Override
protected ViewerFilter createFilter() {
return new FooOutlineFilter();
}
}

Hi Porter,
this snippet makes the assumption that you have something like
public static ImageDescriptor getImageDescriptor(String path) {
return imageDescriptorFromPlugin(PLUGIN_ID, path);
}
in your ConcreteMyDslActivator (extends MyDslActivator).
It the ConcreteMyDslActivator does not exist, you have to create it on
your own in your UI plugin (and change the Manifest.MF accordingly).
The alternative is to use #imageDescriptorFromPlugin(String, String)
directly.
Thanks for the hint, we'll fix the docs as soon as possible.
Regards,
Sebastian
