How to set the selection programmatically? [message #1408826]

Is a possible to set the selection to a PictogramElement programmatically?

I was vague with my original question. I basically want to know if there is a way to avoid the de-selection of the current element when the property that adds the diamond is checked or at least a way to re-select it back programmatically. See attached screencast.

Note that in DefaultToolBehaviorProvider you have method getSelection. I don't know if it can be useful for you as in my case it is invoked only when I hover any shape. I use it to deselect labels:

	@Override public PictogramElement getSelection(PictogramElement originalPe, PictogramElement[] oldSelection) {
		if(oldSelection.length > 1) {
			List<PictogramElement> withoutLabels = new ArrayList<>();
			for(PictogramElement pe : oldSelection) {
				String labelProperty = Graphiti.getPeService().getPropertyValue(pe,	SicConstants.LABEL_PROPERTY);
				if (Boolean.parseBoolean(labelProperty)) continue;
				withoutLabels.add(pe);
			}
			PictogramElement[] withoutLabelsArray = new PictogramElement[withoutLabels.size()];
			withoutLabels.toArray(withoutLabelsArray);
			getDiagramTypeProvider().getDiagramBehavior().getDiagramContainer().selectPictogramElements(withoutLabelsArray);
		}
		return null;
	}

Thanks Marek for your suggestion.

I was able to workaround this by using this call in my AbstractUpdateFeature::update() implementation.

getActiveEditor().getDiagramBehavior().setPictogramElementForSelection(containerShape);

The new attached screencast shows the result I wanted.

Cheers!

DiagramEditor offers a method selectPictogramElements that does exactly
that.

I tried that, but it didn't work.

getActiveEditor().selectPictogramElements(new PictogramElement[] {containerShape});

Hm, the passed container shape instance must exist on the diagram,
especially it must live in the same editing domain/resource set as the
editor uses. Maybe that is causing trouble here?

Yes, all live in the same editing domain and resource set

ContainerShape containerShape = (ContainerShape) context.getPictogramElement();
EditorAssist.getActiveEditor().getDiagramBehavior().setPictogramElementForSelection(containerShape);
Goal goal = (Goal) getBusinessObjectForPictogramElement(containerShape);
		
Object a = EditorAssist.getActiveEditor().getEditingDomain();
Object c = TransactionUtils.getDomain(containerShape);
Object d = TransactionUtils.getDomain(goal);
		
if (a == c && c == d && a == d) {
   System.out.println("YES, they all have the same editing domain and resourse set");

In the below coding you call setPictogramElementForSelection, but I
recommended to use selectPictogramElements. Have you tried with that as
well? The first one just sets a member variable for later selection, while
the second one really does the selection.

Yes, I tried with selectPictogramElements, but nothing gets selected. setPictogramElementForSelection works though.

Maybe I'm not calling selectPictogramElements from the right place. I'm calling them from the AbstractUpdateFeature::update(IUpdateContext context) method.

I have just made selection in UpdateFeature.

	
        @Override
	public boolean update(IUpdateContext context) {
		if(!updateNeededChecked) 
			if(!this.updateNeeded(context).toBoolean()) return false;
		
		boolean updated = false;
		if(superUpdateNeeded) updated = updated | super.update(context);
		
		ContainerShape parent = (ContainerShape) context.getPictogramElement();
		Task be = (Task) getBusinessObjectForPictogramElement(parent);
		
		if(descUpdateNeeded)    updated = updated | descUpdate   (parent, be);
		if(inputsUpdateNeeded)  updated = updated | inputsUpdate (parent, be);
		if(outputsUpdateNeeded) updated = updated | outputsUpdate(parent, be);
		if(atomicUpdateNeeded)  updated = updated | atomicUpdate (parent, be);
		if(paramsUpdateNeeded)  updated = updated | paramsUpdate (parent, be);

		if(updated) {
			getDiagramBehavior().getDiagramContainer().selectPictogramElements(new PictogramElement[] {});
			getDiagramBehavior().getDiagramContainer().selectPictogramElements(new PictogramElement[] { parent });
		}
		
		return updated;
	}

I needed to reselect pictogram element to refresh properties tab.

Works correctly.
