Member Function Documentation

void SmartCursorWatcher::characterDeleted ( SmartCursor *  cursor,
bool  deletedBefore 
) [virtual]

The character immediately surrounding the cursor was deleted.

If both characters are simultaneously deleted, positionDeleted() is called instead.

Parameters:
cursor pointer to the cursor which generated the notification.
deletedBefore true if the character immediately before was deleted, false if the character immediately after was deleted.

Definition at line 40 of file cursorfeedback.cpp.

void SmartCursorWatcher::characterInserted ( SmartCursor *  cursor,
bool  insertedBefore 
) [virtual]

A character was inserted immediately before or after the cursor, as given by insertedBefore.

Parameters:
cursor pointer to the cursor which generated the notification.
insertedBefore true if a character was inserted before cursor, false if a character was inserted after

Definition at line 44 of file cursorfeedback.cpp.

void SmartCursorWatcher::deleted ( SmartCursor *  cursor  )  [virtual]

The SmartCursor instance specified by cursor is being deleted.

Parameters:
cursor pointer to the cursor which is about to be deleted. It is still safe to access information at this point.

Definition at line 73 of file cursorfeedback.cpp.

void SmartCursorWatcher::positionChanged ( SmartCursor *  cursor  )  [virtual]

The cursor's position was changed.

Parameters:
cursor pointer to the cursor which generated the notification.

Definition at line 32 of file cursorfeedback.cpp.

void SmartCursorWatcher::positionDeleted ( SmartCursor *  cursor  )  [virtual]

The cursor's surrounding characters were both deleted simultaneously.

The cursor is automatically placed at the start of the deleted region.

Parameters:
cursor pointer to the cursor which generated the notification.

Definition at line 36 of file cursorfeedback.cpp.

void SmartCursorWatcher::setWantsDirectChanges ( bool  wantsDirectChanges  ) 

Set whether this watcher should be notified of changes that happen directly to the cursor, e.g.

by calls to SmartCursor::setPosition(), rather than just when surrounding text changes.

Parameters:
wantsDirectChanges whether this watcher should receive notifications for direct changes.

Definition at line 53 of file cursorfeedback.cpp.

bool SmartCursorWatcher::wantsDirectChanges (  )  const

Returns whether this watcher wants to be notified of changes that happen directly to the cursor, e.g.

by calls to SmartCursor::setPosition(), rather than just when surrounding text changes.
