Member Function Documentation
void KTextEditor::SmartRangeNotifier::caretEnteredRange | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::View * | view | |||
) | [signal] |
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
void KTextEditor::SmartRangeNotifier::caretExitedRange | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::View * | view | |||
) | [signal] |
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
void KTextEditor::SmartRangeNotifier::childRangeInserted | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::SmartRange * | child | |||
) | [signal] |
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.
void KTextEditor::SmartRangeNotifier::childRangeRemoved | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::SmartRange * | child | |||
) | [signal] |
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.
void KTextEditor::SmartRangeNotifier::mouseEnteredRange | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::View * | view | |||
) | [signal] |
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
void KTextEditor::SmartRangeNotifier::mouseExitedRange | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::View * | view | |||
) | [signal] |
The mouse cursor on view exited range
.
- Todo:

- Parameters:
-
range pointer to the range which generated the notification. view view over which the mouse moved to generate the notification
void KTextEditor::SmartRangeNotifier::parentRangeChanged | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::SmartRange * | newParent, | |||
KTextEditor::SmartRange * | oldParent | |||
) | [signal] |
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.
void KTextEditor::SmartRangeNotifier::rangeAttributeChanged | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::Attribute::Ptr | currentAttribute, | |||
KTextEditor::Attribute::Ptr | previousAttribute | |||
) | [signal] |
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
void KTextEditor::SmartRangeNotifier::rangeContentsChanged | ( | KTextEditor::SmartRange * | range, | |
KTextEditor::SmartRange * | mostSpecificChild | |||
) | [signal] |
The contents of the range changed.
- Warning:
- 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 pointer to the range which generated the notification. mostSpecificChild the child range which both contains the entire change and is the furthest descendant of this range.
void KTextEditor::SmartRangeNotifier::rangeContentsChanged | ( | KTextEditor::SmartRange * | range | ) | [signal] |
The contents of the range changed.
- Parameters:
-
range pointer to the range which generated the notification.
void KTextEditor::SmartRangeNotifier::rangeDeleted | ( | KTextEditor::SmartRange * | range | ) | [signal] |
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.
void KTextEditor::SmartRangeNotifier::rangeEliminated | ( | KTextEditor::SmartRange * | range | ) | [signal] |
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.
void KTextEditor::SmartRangeNotifier::rangePositionChanged | ( | KTextEditor::SmartRange * | range | ) | [signal] |
The range's position changed.
- Parameters:
-
range pointer to the range which generated the notification.
void SmartRangeNotifier::setWantsDirectChanges | ( | bool | wantsDirectChanges | ) |
Set whether this notifier should notify 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 provide notifications for direct changes.

bool SmartRangeNotifier::wantsDirectChanges | ( | ) | const |
Returns whether this notifier will notify 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.
