I've used the paint() method on it ( even if it's not necessary on a QGraphicsView ) to reduce absurdely the number of items that are inserted on the QGraphicsScene ( each small line of the profile should be an item if it was not for this, it's like that on the old profile. ) and thus reducing the memory consumption, speed and so on.

/* This is the Profile Item, it should be used for quite a lot of things

on the profile view. The usage should be pretty simple:
|
|
|
|
DiveProfileItem *profile = new DiveProfileItem();
|
|
profile->setVerticalAxis( profileYAxis );
|
|
profile->setHorizontalAxis( timeAxis );
|
|
profile->setModel( DiveDataModel );
|
|
profile->setHorizontalDataColumn( DiveDataModel::TIME );
|
|
profile->setVerticalDataColumn( DiveDataModel::DEPTH );
|
|
scene()->addItem(profile);
|
|
|
|
This is a generically item and should be used as a base for others, I think...
