BMediaTheme

A BMediaTheme is an object that, given a BParameterWeb, can create a BView containing all the controls needed to configure the BControllable node represented by the BParameterWeb. You can then add the returned BView to a window so the user can configure the node to their liking.

The resulting BView contains not only the controls for configuring the parameters available in the node, but also indicates the data flow path through the node.

The BeOS includes the standard theme, which provides the system default look to media controls, as seen in the Audio and Video preference applications beginning with Release 4.

If you want to change the look of media controls within the BeOS, you can write your own BMediaTheme and install it as the default system theme by calling SetPreferredTheme(). If you want to write a new theme and provide the ability for the user to enable it as the new system theme, you'll need to write an application that calls SetPreferredTheme().

If you want to return to the default system theme, you should call SetPreferredTheme(NULL). Make sure you don't have any theme views instantiated in your application when you do so.
