Editing WoW:API UIObject SetAlpha

{{widgetmethod}}

Sets the alpha (transparency) of the given object.

 MyObject:SetAlpha(alpha)

== Parameters ==
=== Arguments ===
* alpha (number) - a floating-point number between 0 and 1: 1 is fully opaque, 0 is transparent (in fact, invisible).

== Example ==
Makes frame <tt>MyFrame</tt> translucent, more visible than not:
 MyFrame:SetAlpha(.75);

Fade the whole UI so that it becomes barely visible:
 UIParent:SetAlpha(0.1);

== Notes ==
* As of [[2.1.0_consolidated_changes#Frames|patch 2.1.0]], transparency propagates down through all child objects.
: ''"Frame alpha now propagates in the same way as scale (though is clamped between 0 and 1 on each object). This means you can cleanly fade the whole UI or specific frame assemblies."''
