### Description

Set Alpha can be used to set the transparency of a window.  
NOTE: If you set the Alpha of a window too low it will not accept mouse clicks. Windows limitation: Currently the plug-in can only set the transparency of Application Window, not the individual database windows.  
Seems not to work for FileMaker 11 on Windows with document windows. So please test if it works on your version.  
### Examples

Set the Transparency of a window by name

 Let(  
\[  
/\*-----------------PARAMETERS--------------------\*/  
  
FileMakerApplicationWindowName =  
Case(  
Position(Get ( ApplicationVersion ); "Advanced"; 1; 1);"FileMaker Pro Advanced";  
"FileMaker Pro"  
);  
  
WindowRef =   
  
MBS (   
"[Window.FindByTitle](WindowFindByTitle.md)";  
FileMakerApplicationWindowName  
);  
  
Alpha = .5  
  
\];  
/\*-------------------FUNCTION----------------------\*/
