/**
* @author Mark Larkin, Conway Institute, UCD. mark.larkin@ucd.ie
*
* Changes:
*
* 20-02-07,Nigel Brown(EMBL): made getExtraRowNum() a const member so it can
* be called inside sizeHint(); added eventFilter() to catch containing
* viewport resize events; added single setMaxNameLength() member to compute
* maximum typeset text width; added computeSize() member to determine final
* widget size from text size or containing viewport size; added
* horizontalMargin member: Widget now fills viewport and resizes neatly.
*
* 11-04-07,Nigel Brown(EMBL): Added new member 'ctrlPressed'.
*
* 12-4-07, Mark Larkin, Removed destructor. No need to delete QObjects.
*
* 25-04-07,Nigel Brown(EMBL): removed 'shiftPressed', 'ctrlPressed' members
* and the keyPressEvent() and keyReleaseEvent() handlers. These are now
* handled by the external KeyController class.
*
* 09-05-07,Nigel Brown(EMBL): added 'mousePressed'. Renamed
* rowSelected' to 'firstRow' and added 'secondRow'. 'scrollArea' and
* registerScrollArea() allowing the instance to know its own
* containing QScrollArea (This is not the same as parentWidget()).
*
* 27-06-07,Nigel Brown(EMBL): For screen layout balancing: renamed
* numSequencesSoFar as numSequences, added numSequences2, which records the
* number of sequences in the *other* profile window; Added setNumSequences2().
