                                        AbstractProperty

Abstract base class for IProperty implementations.

Handles listener management for ValueChangeListeners and IReadOnlyStatusChangeListeners.

Instance Methods

[hide private]

__init__(self)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

isReadOnly(self)
Override for additional restrictions on what is considered a read-only property.

source code

setReadOnly(self, newStatus)
Sets the IProperty's read-only mode to the specified status.

source code

__str__(self)
Returns the value of the IProperty in human readable textual format. source code

addListener(self, listener, iface=None)
Registers a new read-only status change listener for this IProperty.

source code

addCallback(self, callback, eventType=None, *args)

source code

removeListener(self, listener, iface=None)
Removes a previously registered read-only status change listener.

source code

removeCallback(self, callback, eventType=None)

source code

fireReadOnlyStatusChange(self)
Sends a read only status change event to all registered listeners.

source code

fireValueChange(self)
Sends a value change event to all registered listeners.

source code

getListeners(self, eventType)

source code

getCallbacks(self, eventType)

Method Details

[hide private]

init(self)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

isReadOnly(self)

source code

Override for additional restrictions on what is considered a read-only property.

Returns:: True if the IProperty is in read-only mode, False if it's not
Overrides: property.IProperty.isReadOnly

setReadOnly(self, newStatus)

source code

Sets the IProperty's read-only mode to the specified status.

This functionality is optional, but all properties must implement the isReadOnly mode query correctly.

Parameters:

newStatus - new read-only status of the IProperty

Overrides: property.IProperty.setReadOnly

(inherited documentation)

str(self)
(Informal representation operator)

source code

Returns the value of the IProperty in human readable textual format. The return value should be assignable to the setValue method if the IProperty is not in read-only mode.

Returns:: String representation of the value stored in the IProperty
Overrides: object.__str__
