Hit test through a widget

I have made an interface for selected objects amd it appears in front of item. The problem is that, once it is visible, I cannot click anymore on the item (even if I leave a hole in the UI).

The UI has the following structure:

SizeBox → CanvasPanel → Buttons

I tried to change the Visibility values on SizeBox and CanvasPanel, but with no results.

Any ideas what can I do to achieve this goal?

I think I have solved this.

As soon as I disabled the “Enable Mouse Over Events” in my player controller, it began to work as I wanted.

The next question would be, is it possible to have that option enabled and still have the hit as I expected?
