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 78 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 82 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 94 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 98 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 70 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 74 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 106 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 102 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 62 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 66 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 90 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 86 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 58 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 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.
