Multiple commands for events in trees

[nickdodd79]

Not sure if I have missed something in the documentation, but I need to handle multiple events on items in a tree (click, double click and enter). I have an extension that displays and runs gulp tasks within a workspace.

At the moment, I have a command that tracks the selection of an item, which in turn controls relevant nav icons depending on the item's state (e.g. if idle an execute icon is shown, if executing a terminate icon is shown).

I am hoping to add a feature where users a can double click or press enter to execute a task, but still allow selection to be activated with a single click. This would require multiple commands to be registered for a tree item.

Can a change be made so TreeItem instances can have event driven commands. Something like:

clickCommand
keypressCommand
doubleClickCommand

Which will also provide the triggered event object. In the example of keypress, providing the event will allow the key that activated the event to be resolved.

There are plans to support double click command but not keypress. See #39601
