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
GTK.Widget	`widget`: The GTK widget
Inherited from _gtkindi_widgetlist_handler
list of GTK.Widget	`widgetlist`: The list GTK widgets to be connected
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
