* QGraphicsView drawing artifacts due to rounding errors.Bjørn Erik Nilsen2010-05-031-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Found during investigation of QTBUG-8820, and clearly visible in examples/graphicsview/diagramscene when slowly moving an item out of the viewport (left and top edge). Caused by two problems: 1) Using QRectF::toRect() instead of QRectF::toAlignedRect(). 2) Didn't adjust the item's bounding rect properly in drawSubtree(). QRectF::toRect() is completely useless since all the coordinates are rounded to the nearest integer. E.g. QRectF(-0.4, -0.4, 10.4, 10.4).toRect() -> QRect(0, 0, 10, 10), whereas toAlignedRect() returns QRect(-1, -1, 11, 11). Then when we have a proper aligned rect, we have to adjust it by 2 pixels in all directions (or 1 pixel in case of QGraphicsView::DontAdjustForAntialiasing). At first glance this adjustment seems too much, since one would assume adjusing the QRectF by 0.5 before using toAlignedRect() would be sufficient. That's sufficient in an untransformed world with pens using BevelJoin. However, the story is completely different as soon as the world is transformed or the pens use a different join. It's basically complicated (in some cases impossible) to calculate a pixel perfect aligned QRect, so instead we adjust by the amount of pixels required in the worst case. This commit also includes some optimizations for QRegion updates (since I anyways had to change the code). There's no point in using QRegion granularity if the viewport update mode is either FullViewportUpdate or BoundingRectViewportUpdate. Auto tests adjusted and new ones included.

* Add QGraphicsItem::stackBefore(), and fix Z ordering bugs.Andreas Aardal Hanssen2009-09-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we changed the sibling stacking order to be defined (4.5) instead of undefined (4.2, 4.3, 4.4), the need to control this stacking order arose. Before we could just say the order was random, but stable, and the only way people could rely on order was to set Z. Now, when the default order is defined as "insertion order", people start relying on this order, and incidentally they want more control. In QML, the need to have insertion order semantics is very evident as the order you define the elements in QML more strongly implies a graphical stacking order than the imperative order they get when added in C++. This change adds QGraphicsItem::stackBefore(const QGraphicsItem *), which works similarily to QWidget::stackUnder(). It moves the item in front of the sibling item passed as an argument. While implementing this function, and writing tests for how this function behaves in combination with Z values, I found that the code we had for updating siblingIndex was broken in the case where you remove an item from the middle of the children list. In this case newly added items would be assigned the same sibling index order as one that's already in the list. So in order to get the tests to pass I had to fix this bug as well.. The approach is to sort the children list by insertion order, so that we can fix up the sibling indexes. Performancewise this has little implications. If there are gaps in the sibling index list, which only occurs if you remove an item from the middle of the children list, will the sibling index list be adjusted / corrected before used (for example, by stackBehind()). Multiple calls to stackBehind will be fast, and the list is flagged for resorting (including Z order). Reviewed-by: jasplin

They can be activated and deactivated just like windows and focus is handled just like with windows. The main difference is that panels are more light-weight. There's less built-in functionality (e.g., clicking a panel doesn't automatically activate nor raise it). This patch also introduces QGraphicsItem::panel(), QGraphicsItem::isPanel(), and QGraphicsItem::isActive(), as well as QGraphicsScene::activePanel(), QGraphicsScene::setActivePanel(). and QGraphicsScene::isActive().

Also, we are not connecting to cloned signal but only to the orginial ones. For example, destroyed(QObject * = 0) would generate two signal, we now only connect to the first one.

The issue is this: Each item can delegate another item to be its focus proxy. That item can be a parent or child, or something completely unrelated. Either of the two items can be deleted independently. The former solution was to store backpointers in a map in the scene. Problem is, the items may not be in a scene when this happens, they may be removed from the scene, and the items may be moved between two scenes. The bad part about this fix is that it adds another pointer to QGraphicsItemPrivate. Reviewed-by: Shane Kearns <shane.kearns@sosco.com>

* | | Make tst_QGraphicsEffectSource::boundingRect happy.Bjørn Erik Nilsen2009-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot modify the transformPtr directly because we might want to use the original transform later. The problem in this particular case was that we called source->pixmap() (which modified the transformPtr), then source->boundingRect(Qt::DeviceCoordinates) which in turn used wrong transform to map the bounding rect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following QWidget's behavior, you can not assign any item in the same scene as a focus proxy for another item. Also supports nested focus proxies. You can only assign items in the same scene as focus proxies. Autotests are included. Reviewed-By: mbm
