I was trying to show a popup menu when right clicking on a label. I saw that there's a button parameter in EvMouse which can be used to distinguish between mouse buttons, but I didn't find a way to get the same behaviour on a label.

I understand that the only way of handling clicks in labels is through the label_OnClick function and the EvText event which doesn't have an equivalent to the button parameter. Would it be possible to support this use case?
