Hello Again,

Is it possible to activate a property to hide a widget? For example, I have a button that I want to hide completely 
under certain conditions. I have looked at all the resources but found no appropriate flag or property. I imagine the 
other way is to have a canvas, e.g. image area as a background, and hide it behind that.Which would bring me to the 
question, what is the name of the z-axis property to set in code?
