Widget Blueprint for mesh initiate or trigger

Sounds a bit like you require a step-by-step guidance on every feature, this is not sustainable. It would turn into private tutoring which is beyond the scope of this forum, at least for me.


Have a look at tutorials, what you’re trying to do has been covered too many times. YT is choke full of examples of how to interact with widgets.

In short:

  • look into how widgets handle input - keypresses and mouse clicks.
  • you can override those behaviours; a native Image could override its onMouseDown so its surface becomes clickable
  • or you could have the entire widget override onMouseButtonDown so all of its Visible area registers mouse clicks
