Hello Sedona peeps!

Inside the linkEvent call back I need to set a slot to it's default of null when a link is deleted.

I am given:

link.toSlot

... which is a byte ID.

How do I massage this to a Slot type in order to use the assignment:

mySlot := null



Thanks!

Hi,

why you don't use this method in Component?

setToDefault
public virtual void setToDefault(Slot slot)
Set property to a default value. Called when a link is removed from an input slot.

best regards


pozdrawiam

Thanks Mateusz ... the trick is to convert link.toSlot which is a byte id of the comp's slot ... to a type Slot.

... also ... it seems this should run anyway when a link is broken.
Doesn't seem to for me.

I set my input as null but when the link if deleted it remains true or false.

I am calling super.linkEvent(eType, link) ... I assumed I would have to.

Could this be messing things up?

I always use setToDefault method if I want to set own value after link delete :

class MyComp extends Component {
property bool in := null;

override void setToDefault(Slot slot) {
  super.setToDefault(slot);
  if (slot == MyComp.in) {
    in := null;
  }
}

if you want convert slot id to Slot use:

this.type.slot(slotId);
