Dear Chris,
I see that QTransform() is used in Panner:drawItems to get an identity matrix.
So if we implemented scaling, we'd need to somehow obtain horizontal and
vertical transformation information to feed to QTransform().
Here is a snippet of the current code starting at line 185:
painter->save();
painter->setTransform(QTransform());
painter->drawPixmap(0, 0, m_cache);
painter->restore();
QTransform::fromScale ( qreal sx, qreal sy ) for qt 4.5
or
QTransform::scale ( qreal sx, qreal sy ) for eariler
Creates a matrix which corresponds to a scaling of sx horizontally and sy
vertically. This is the same as QTransform().scale(sx, sy) but slightly faster.
So each slot would need to set panner scale members before calling on the
update to the panner.
Is this correct?
Sincerely,
Julie S.
