[Gambas-user] How to create MediaControl with specific Type?

[vuott at tiscali.it]

Hello, 
you have use a "MediaPipeline" as MediaContatiner Parent.

Exemplum: 
 _Public hControl As MediaControl_ 
_ Public Sub Main()_

_
Dim pl As MediaPipeline_

_ pl = New MediaPipeline _

_ hControl = New
MediaControl(PL, "fdsink")_ 

 ...etc....

and _ hControl["fd"] = ...
_doesn't want a String, it wants an "Integer" value.

It seems that to specify a Type, a Parent must also be specified else I
