do_region_changed(current_offset, last_offset) virtual
Parameters:

Signal Details

Atspi.Accessible.signals.region_changed(accessible, arg1, arg2)
Signal Name:

region-changed

Flags:

RUN_LAST

Parameters:
  • accessible (Atspi.Accessible) – The object which received the signal
  • arg1 (int) – an integer specifying the current offset of the text being read, if the object is textual.
  • arg2 (int) – an integer specifying the ending offset of the text being read, if the object is textual.

The signal “region-changed” is emitted by a screen reader to indicate that it is now reading or tracking a new object, or, a new piece of text within an object. This allows a magnifier to gain the information needed to highlight the object that the screen reader is reading.
