Tree click work like a right-click for some Item nodes

I have a Tree working fine with Actions defined on various Item nodes to handle a right-click with its popup context menu showing those Actions.

Is there a way for me to specify that a given Item/node should work the same way when it’s just a regular click? That is, I’d like the regular click to also open the popup context menu showing the Actions defined for it. (I don’t want all clicks to work like a right click, but only some – in my case it’s the parent nodes that have children nodes that I’d like to do this).

Is this possible? I’d rather not ignore or display a message on a click and just do the same thing as if they right-clicked the item.

Thanks…

If I can’t make the regular click open up the Actions popup like a right click, is there a programmatic way to trigger a right-click on the same item?
