* More re-factoring of Graphics View's update mechanism.Bjørn Erik Nilsen2009-06-094-83/+185
| | | | | | | | | This time with a recursive approach of processing dirty items. I've kept the previous approach using a dirty list, but the recursive one is now the default. Use QT_GV_USE_DIRTY_LIST=1 to swap. I've also cached the item's device transform in both cases so that we can re-use it later when drawing the item.
* Introduce QGraphicsItem::ItemHasNoContents.Andreas Aardal Hanssen2009-06-091-2/+2
| | | | | | | | | | | This flag helps optimize the case where an item is used only as a transformation node in a scene graph, and where the item itself doesn't paint anything. This is the default for FxItem (the subclasses that do paint enable the HasContents flag). This lets Graphics View know whether there's any point in setting up the world transform, opacity and other things. Reviewed-by: Lars

* simplify opacity handling in QGraphicsItemLars Knoll2009-06-091-4/+2
| | | | | | | | | Greatly simplify how we handle opacity and store it as a member in QGraphicsItemPrivate. Remove the caching of effectiveOpacity. It's faster to calculate it on the fly, and the recursive painting algorithm will make even that need go away. Reviewed-by: Andreas
* get rid of the hasTransform flag in QGraphicsItemLars Knoll2009-06-092-235/+9
| | | | | | | | Since the transform is now a pointer in QGraphicsItemPrivate, we can use this pointer directly and there's no need for a separate bitflag anymore. Reviewed-by: Andreas
* Remove scene transform cache from QGraphicsItem.Andreas Aardal Hanssen2009-06-091-0/+232
| | | | | | | | | Now that we have a recursive painting algorithm these types of optimizations are no longer necessary. In fact they only cause more problems and clutter up the code unnecessarily. Removing this also removes extra overhead from moving and transforming items. Reviewed-by: Lars

* greatly speed up QTransform::mapRect() for projective transformsLars Knoll2009-06-091-10/+2
| | | | | | | | | The code so far was converting the rect to a painterpath, mapping that one and then taking the bounding rect. It is actually sufficient to simply map the four corners of the rectangle and take the bounding rect of these four points even in the projective case. Reviewed-by: Andreas

* simplify and cleanup handling of transformations in QGraphicsItemLars Knoll2009-06-094-464/+23
| | | | | | | | | | | Removed some experimental code to handle scaling and rotating around different axis. It cuased setTransform and transform not to behave symmetrically and caused some performance regressions. Additionally moved the QTransform out of the (relatively slow) extra list and made it a pointer in QGraphicsItemPrivate. Reviewed-by: Andreas
* Massive re-factoring of Graphics View's update mechanism.Bjørn Erik Nilsen2009-06-099-380/+253
| | | | | | | | | | | This is work-in-progress, so don't expect everything to work perfectly. Most of the auto-test pass and examples and demos seem to run fine. Unfortunately I'm too tired to write about the actual update mehanism now, but it's faster than the old approach (if that helps:)). There's more to optimize, but I'll come back to that later. I need some sleep now :) To be continued.
