FreeLists / haiku-appserver / [haiku-appserver] App Activation

[Ingo Weinhold <bonefish@xxxxxxxxxxxxxxx>]

Howdy,

the application roster has the notion of the active application, which 
simply is the app that owns the currently active window. Since the 
registrar knows nothing about windows, it needs some help from the app 
server. I think what is required is the following:

1) The app server needs to receive and process app activations requests (as 
issued by BRoster::ActivateApp()).

2) The app server needs to notify the registrar when the active app changed.

The second part should be relatively easy. If the app server is started by 
the Bootscript after the registrar (which should be no problem anymore), it 
will have a fully working BRoster and can simply send a message to the 
registrar (BRoster::Private::SendTo()).

Regarding the first part, BRoster::ActivateApp() could send the request 
directly to the app server. Since there might not exist a BApplication when 
the method is invoked, sending it to the port that receives the 
BApplication registration (the one called SERVER_PORT_NAME) might be the 
most sensible choice. But I guess you guys know best...

CU, Ingo
