* Fixes: Simplify the cut-offs and be more agressive :-)Bjoern Erik Nilsen2009-04-061-7/+14
| | | | | AutoTest: Still pass. Details: It's easier to read and understand the code now.
* Fixes: Discard update requests if possible.Bjoern Erik Nilsen2009-04-061-0/+6
| | | | | | | | AutoTest: Still pass. Details: Update requests can be discarded if the item itself is clipped away and the item clips all its children to shape. This cut-off is extremely effective (and aggressive:))

* Fixes: Clever invalidating of the cached clip path.Bjoern Erik Nilsen2009-04-061-2/+16
| | | | | | | | RevBy: Andreas AutoTest: still pass Details: Adds emptyClipPath bit, a cut-off to test if the item has an empty clip path (i.e., is clipped away). Also adds code for invalidating the cache from inside setPos().
* Fixes: Compile on funky scratchbox ARM compiler.Bjoern Erik Nilsen2009-04-061-1/+1

* Fixes: Get rid of lots of calls to qFuzzyCompare.Bjoern Erik Nilsen2009-04-061-0/+6
| | | | | | | RevBy: Olivier AutoTest: Still pass. Details: Items usually don't have effective opacity, i.e. it is 1.0, so don't bother doing fuzzy compare if that's the case.
* Fixes: Optimization: Cache QGraphicsItem::clipPath().Bjoern Erik Nilsen2009-04-061-0/+14
| | | | | | RevBy: Alexis AutoTest: Still pass Details: No-brainer.
* Fixes: Be a bit more smarter when calling setGeometry from itemChangeAlexis Menard2009-04-061-1/+1
| | | | | | | | RevBy: bnilsen AutoTest: Bench Details : if we come from setPosHelper (so itemChange) we don't need to do all the stuff regarding the size in setGeometry because the size doesn't change. I remove two calls to fullUpdateHelper and update() because prepareGeometryChange already call updateHelper and setPosHelper call fullUpdaterHelper too so we don't need to call them inside setGeometry. We can only call prepareGeometryChange only if we don't come from setPos.
* Fixes: Speed up QGrahicsItemPrivate::effectiveOpacity().Bjoern Erik Nilsen2009-04-061-0/+2

* Long live Qt 4.5!Lars Knoll2009-03-231-0/+281
