Detailed Description

The namespace containing a toolkit used by the Openbox window manager, and also for use by external applications that wish to present a similar visual appearance to Openbox.


Compounds

class  Application
class  AppWidget
struct  Atoms
 The atoms on the X server which this class will cache. More...
