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.
Installing a Theme Add-on¶
Theme add-ons belong at /boot/home/config/add-ons/media/themes. They can have any name you like.
Warning
At this time, theme add-on support has not been sufficiently tested and may or may not work. If you have problems with it, please file a bug report at http://bebugs.be.com.
