                        CaretChange

Event that fires when the caret moves in an accessible.

This class registers its name and whether it should be monitored by default in an AEMonitor using the Base.registerEventType function when this module is first imported. The AEMonitor can use this information to build its menus.

init(self, por, text, text_offset, added=None, **kwargs)
(Constructor)

source code

Calls the base class (which set the event priority) and then stores the text and offset to be passed along to the Tier as part of the event.

Parameters:

por (POR) - Point of regard
text (string) - The text inserted, deleted or the line of the caret
text_offset (integer) - The offset of the inserted/deleted text or the line offset when movement only
added (boolean) - True when text added, False when text deleted, and None (the default) when event is for caret movement only

Overrides: Base.AccessEngineEvent.__init__

str(self)
(Informal representation operator)

source code

Returns a human readable representation of this event including its name, its text, its text offset, and whether the text was added, removed, or moved.

Returns: string: Information about this event
Overrides: Base.AccessEngineEvent.__str__

execute(self, tier_manager, view_manager, **kwargs)

source code

Contacts the TierManager so it can manage the caret change event.

Parameters:

tier_manager (TierManager) - TierManager that will handle the event
kwargs (dictionary) - Packed references to other managers not of interest here

Returns: boolean

True if there is an active view, False if not to delay execution of this event until there is

Overrides: Base.AccessEngineEvent.execute

getFocusPOR(self)

source code

Returns the POR for caret movement events. Used by Tier to maintain a focus POR.

Returns: POR

Point-of-regard for this focus event

Raises:

AttributeError - When the event does not represent a change in the focus

getDataForTask(self)

source code

Fetches data out of this CaretChange for use by a Task.CaretTask.

Returns: dictionary

Dictionary of parameters to be passed to a Task.CaretTask as follows:

por: The POR of the accessible in which the caret moved
text: The text inserted, deleted or the line of the caret
text_offset: The offset of the inserted/deleted text or the line offset when movement only
added: Boolean that is True when the text was added

Overrides: Base.AccessEngineEvent.getDataForTask
