Known Subclasses:
_entryhandler, _labelhandler, _rangehandler, _switchlabelhandler

A base class for handlers being called on reception of an INDI element which update a GTK widget
Method Summary
  __init__(self, devicename, vectorname, elementname, widget)
indielement get_element(self)
Returns the indielement this handler is associated with.
indivector get_vector(self)
Returns the indivector this handler is associated with.
  on_gui_changed(self, widget, event)
NoneType update_indi_element(self, element)
Called when the widget has changed and the INDI element needs to be updated
    Inherited from _gtkindi_widgetlist_handler
NoneType set_bidirectional(self)
installs callbacks of the GUI that will call the function _blocking_on_gui_changed if the user changes the the GUI object associated with this gui_indi_object_handler .
NoneType unset_bidirectional(self)
uninstalls the GUI callback installed with set_bidirectional (see set_bidirectional for details)
    Inherited from gui_indi_object_handler
NoneType on_blocked(self, *args)
The method _blocking_on_gui_changed is called by the GUI, in order to inform us, that a widget has changed.
NoneType _blocking_on_gui_changed(self, *args)
Called by the GUI whenever the widget associated with this handler has changed.
    Inherited from _blocking_indi_object_handler
NoneType _block(self)
activates the block.
BooleanType _is_blocked(self)
Return True if blocked , False otherwise
NoneType _unblock(self)
releases the block.
NoneType configure(self, *args)
This method will be called at least once by indiclient.
NoneType indi_object_change_notify(self, *args)
This method activates the block, calls the method on_indiobject_changed (It is called by bigindiclient.process_events each time an INDI object has been received)
NoneType on_indiobject_changed(self, *args)
While this function is called the block is active.

Instance Variable Summary

    Inherited from _blocking_indi_object_handler
IntType _blocked: A counter incremented each time the _block method is called and decremented by _unblock, >0 means blocked, ==0 mean unblocked
    Inherited from indi_element_identifier
StringType devicename: The name of the device this handler is associated with
StringType elementname: The name of the indielement this handler is associated with
StringType vectorname: The name of the indivector this handler is associated with
