Detailed Description
A class which provides notifications of state changes to a SmartRange via virtual inheritance.
This class provides notifications of changes to the position or contents of a SmartRange via virtual inheritance.
If you prefer to receive notifications via QObject signals, see SmartRangeNotifier.
Before destruction, you must unregister the watcher from any ranges it is watching.

The caret on view entered range
.
- Todo:
- For now, to receive this notification, the range heirachy must be registered with the SmartInterface as for arbitrary highlighting with dynamic highlighting. Need to add another (and probably simplify existing) method.
- Parameters
-
range pointer to the range which generated the notification. view view over which the mouse moved to generate the notification

The caret on view exited range

The child range child was removed from the current range.
- Parameters

The range's parent was changed.
- Parameters
-
range pointer to the range which generated the notification. newParent pointer to the range which was is now the parent range. oldParent pointer to the range which used to be the parent range.

virtual |
The highlighting attribute of range was changed from previousAttribute to currentAttribute.
- Parameters
-
range pointer to the range which generated the notification. currentAttribute the attribute newly assigned to this range previousAttribute the attribute previously assigned to this range

virtual |
The contents of the range changed.
- Parameters
-
range pointer to the range which generated the notification.
Definition at line 62 of file rangefeedback.cpp.
|
virtual |
The contents of the range changed.
This notification is special in that it is only emitted by the top range of a heirachy, and also gives the furthest descendant child range which still encompasses the whole change (see contents
).
- Parameters
-
range the range which has changed mostSpecificChild the child range which both contains the entire change and is the furthest descendant of this range.
Definition at line 66 of file rangefeedback.cpp.

virtual |
The SmartRange instance specified by range
is being deleted.
- Parameters
-
range pointer to the range which is about to be deleted. It is still safe to access information at this point.
Definition at line 90 of file rangefeedback.cpp.
|
virtual |
The range now contains no characters (ie.
the start and end cursors are the same).
- Parameters
-
range pointer to the range which generated the notification.
Definition at line 86 of file rangefeedback.cpp.
|
virtual |
The range's position changed.
- Parameters
-
range pointer to the range which generated the notification.

void SmartRangeWatcher::setWantsDirectChanges | ( | bool | wantsDirectChanges | ) |
Set whether this watcher should be notified of changes that happen directly to the range, e.g.
by calls to SmartCursor::setRange(), or by direct assignment to either of the start() or end() cursors, rather than just when surrounding text changes.
- Parameters
-
wantsDirectChanges whether this watcher should receive notifications for direct changes.
Definition at line 53 of file rangefeedback.cpp.
bool SmartRangeWatcher::wantsDirectChanges | ( | ) | const |
Returns whether this watcher will be notified of changes that happen directly to the range, e.g.
by calls to SmartCursor::setRange(), or by direct assignment to either of the start() or end() cursors, rather than just when surrounding text changes.
