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.

Member Function Documentation
void SmartRangeWatcher::caretEnteredRange | ( | SmartRange * | range, | |
View * | view | |||
) | [virtual] |
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
Definition at line 77 of file rangefeedback.cpp.
void SmartRangeWatcher::caretExitedRange | ( | SmartRange * | range, | |
View * | view | |||
) | [virtual] |
The caret on view exited 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
Definition at line 81 of file rangefeedback.cpp.
void SmartRangeWatcher::childRangeInserted | ( | SmartRange * | range, | |
SmartRange * | child | |||
) | [virtual] |
The range child was inserted as a child range into the current range.
- Parameters:
-
range pointer to the range which generated the notification. child pointer to the range which was inserted as a child range.
Definition at line 93 of file rangefeedback.cpp.
void SmartRangeWatcher::childRangeRemoved | ( | SmartRange * | range, | |
SmartRange * | child | |||
) | [virtual] |
The child range child was removed from the current range.
- Parameters:
-
range pointer to the range which generated the notification. child pointer to the child range which was removed.
Definition at line 97 of file rangefeedback.cpp.
void SmartRangeWatcher::mouseEnteredRange | ( | SmartRange * | range, | |
View * | view | |||
) | [virtual] |
The mouse cursor 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
Definition at line 69 of file rangefeedback.cpp.
void SmartRangeWatcher::mouseExitedRange | ( | SmartRange * | range, | |
View * | view | |||
) | [virtual] |
The mouse cursor on view exited 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
Definition at line 73 of file rangefeedback.cpp.
void SmartRangeWatcher::parentRangeChanged | ( | SmartRange * | range, | |
SmartRange * | newParent, | |||
SmartRange * | oldParent | |||
) | [virtual] |
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.
Definition at line 105 of file rangefeedback.cpp.
void SmartRangeWatcher::rangeAttributeChanged | ( | SmartRange * | range, | |
Attribute::Ptr | currentAttribute, | |||
Attribute::Ptr | previousAttribute | |||
) | [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
Definition at line 101 of file rangefeedback.cpp.
void SmartRangeWatcher::rangeContentsChanged | ( | SmartRange * | range, | |
SmartRange * | mostSpecificChild | |||
) | [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 65 of file rangefeedback.cpp.
void SmartRangeWatcher::rangeContentsChanged | ( | SmartRange * | range | ) | [virtual] |
The contents of the range changed.
- Parameters:
-
range pointer to the range which generated the notification.
Definition at line 61 of file rangefeedback.cpp.
void SmartRangeWatcher::rangeDeleted | ( | SmartRange * | range | ) | [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 89 of file rangefeedback.cpp.
void SmartRangeWatcher::rangeEliminated | ( | SmartRange * | range | ) | [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 85 of file rangefeedback.cpp.
void SmartRangeWatcher::rangePositionChanged | ( | SmartRange * | range | ) | [virtual] |
The range's position changed.
- Parameters:
-
range pointer to the range which generated the notification.
Definition at line 57 of file rangefeedback.cpp.
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 52 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.
