* Small optimization to QGraphicsItemPrivate::combineTransform(To|From)Parent.Bjørn Erik Nilsen2009-06-191-2/+2
| | | | Every cycle counts :)
* Refactor QGraphicsScene::drawSubtreeRecursive.Bjørn Erik Nilsen2009-06-193-153/+169
| | | | | | | | It's easier to read and maintain the code now. This version is also faster than the old one and makes it easier to implement another cut-off I'm working on. All auto-tests still pass. Examples/demos run fine.

| | | | | | | | | The QtSVG module failed to link because it includes qgraphicsitem_p.h, which had an inlined function (updateHelper) that called an undeclared function (QGraphicViewPrivate::update(Region|Rect))...Resulting in unresolved symbols. Reviewed-by: MariusSO

| | | | | | Broken after: 85f811b849f3b0e0b79e0f1b7bf41512d7f53414 QPainter::worldTransform returns a const reference(!) so we have to make a copy.
* Reduce QTransform operations in QGraphicsView::paintEvent.Bjørn Erik Nilsen2009-06-171-9/+18

* Remove two work-arounds in QGraphicsView::paintEvent.Bjørn Erik Nilsen2009-06-171-4/+0
| | | | | | | | | | | | The accelerate scrolling work-around is fixed by: 8ebe882b077fffedc3ff80fb80d2e181d5e56ab8 The other case was trying to avoid doing expensive QRegion calculations when everything must be repainted anyways. However, it was not entirely correct to assume all paintEvents are triggered by GV itself. Anyways, we don't need it anymore :-) Reviewed-by: Andreas

* | Don't mark ItemHasNoContents items as dirty, ever.Andreas Aardal Hanssen2009-06-161-5/+8
| | | | | | | | | | | | | | | | | | | | The QGraphicsItem::ItemHasNoContents flag ensures that we don't have to ever paint this item. So let's not mark it as dirty at all (items are marked as dirty when updated, moved, or transformed). This is a minor optimization. Reviewed-by: bnilsen
* | Optimization: Don't determine the expose if the item is invisible.Andreas Aardal Hanssen2009-06-151-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | If the item either sets the ItemHasNoContents flag, or if it's invisible but has child items that are not (and ignore parent opacity), then don't bother calculating the item's exposed view rect as the item will not get drawn anyway. This carves down the number of QTransform::mapRect operations by 25% when running the Declarative UI calculator transition. We'll proceed to removing such operations from the markDirty step as well.

* | QGraphicsItems are repainted when outside the view's exposed region.Bjørn Erik Nilsen2009-06-121-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that we used QRect::isEmpty() on the item's bounding rect intersected with the exposed region's bounding rect as a criteria for whether the item should be drawn or not. This does not work as expected with partial updates, where the boundingRect() of the exposed region easily can cover the entire viewport area. The item should *only* be drawn if its bounding rect intersects with the exposed region (and not the exposed region's bounding rect). Auto-test included.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem appears in the chip demo when clicking an item while scrolling the view using the mouse wheel. The problem was that we didn't translate the the item's old painted view rect. There was also a problem when enabling the DontAdjustForAntialiasing flag, causing an item to not redraw its edges. We have to adjust the rectangle by (-1, -1, 1, 1) since QRect() and QRectF() behaves differently. Auto-test (made by Andreas) included. Reviewed-by: Andreas
* | QGraphicsView: Replace update() with updateAll().Bjørn Erik Nilsen2009-06-112-22/+20
| | | | | | | | | | | | | | | | | | | | We have some nice cut-offs when there's a full update pending, but we don't know about it if we call update() directly on the viewport. Instead call QGraphicsViewPrivate::updateAll() which has the same effect, except that it also sets a flag telling us a full update is pending. Reviewed-by: Andreas

QGraphicsObject then simply inherits from QObject and QGraphicsItem. This change is binary compatible as it will leave the vtable layout unchanged and as the parent class doesn't appear in the C++ name mangling on any of our platforms. It's also source compatible as it isn't noticable by existing code. The restriction we have on QGraphicsObject is that we can not add any new virtual methods to it, or add data members to the class. We can however implement a QGraphicsObjectprivate inheriting from QGraphicsItemPrivate if there is a need to add data members to the class. This change will allow us to now have one single base for all QGraphicsItems that inherit from QObject: QGraphicsTextItem, QGraphicsWidget and in the future QFxItem. Having that single base class will significantly simplify our work in the qml engine. Reviewed-by: Andreas

We cannot compute the item's transform relative to the parent by using transformToParent() because the new position is not yet set on the item, that's why the new position is passed into the function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use stable sorting to keep insertion order. This works fine as long as we sort a complete list of siblings in one go, and this list already has items in insertion order. But if we shuffle such a list, the only way to get proper sort order again (with insertion order intact), is if each item has a sibling index. We used to have this, but we don't have it anymore (as it's not needed for NoIndex mode). So until we separate the BSP index into a separate class and add this index there, we add this workaround which uses the toplevelitems list to ensure the items have the correct order.

* | Fix QGraphicsView::render() regression, ensure the right device is passed.Andreas Aardal Hanssen2009-06-091-2/+4
| | | | | | | | | | | | | | | | If we pass the viewport widget as the widget pointer when rendering to an arbitrary painter (e.g., onto a pixmap), we confuse the rendering functions to thinking that it's the viewport's region we should render into. So instead, when drawItems() is passed a painter that's different from the view, we pass 0 for the widget.

| | | | | | | | | | | | | | | | | | | | This change introduced an unexpected interdependency for scenes with items that enable ItemStacksBehindParent, and that contain children that are transformed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | E.g. item->update(QRectF(0, 0, 5, 5)); item->update(); The problem was that we discarded all update requests whenever the item was already marked as dirty. The dirty bit only means it has pending updates (which might be a full update). However, we have a separate bit for full updates (fullUpdatePending) so we have to check against that bit instead.

The problem however, was that we didn't reset the item's dirty state if a full scene update occurred in between, i.e. item->update(); scene.update(); We don't have to calculate the item's dirty rect if a full scene update occurs in between, but we still have to reset its state.
