To handle messages of a particular type, frontends need only define an appropriate handler method. For example, to handle 'stream' messaged, define a '_handle_stream(msg)' method. cCs|jS(s"Returns the current kernel client.(t_kernel_client(tself((s<lib/python2.7/site-packages/qtconsole/base_frontend_mixin.pyt kernel_clientscCs]|j}|dk r¬|jj|jƒ|jj|jƒ|jjj|j ƒ|j jj|j ƒ|j jj|j ƒ|j j j|jƒ|jr¬|jƒq¬n||_|dkrΕdS|jj|jƒ|jj|jƒ|jjj|j ƒ|j jj|j ƒ|j jj|j ƒ|j j j|jƒ|jrY|jƒndS(sdDisconnect from the current kernel client (if any) and set a new kernel client.
