* Add a new optimization flag to QGraphicsItem.Dimitar Asenov2014-03-311-2/+4
| | | | | | | | | | | | | | | | | | The new flag ItemContainsChildrenInShape is similar to the existing flag ItemClipsChildrenToShape. Setting the new flag makes QGraphicsScene assume that children are drawn within the shape of the current item but this is not enforced by clipping. When an application manually ensures this clipping boundary, setting the new flag removes the overhead of enforcing the clip with ItemClipsChildrenToShape, while still allowing other routines to behave more optimially by assuming children are within the shape of the current item. [ChangeLog][QtWidgets][QGraphicsItem] Added the ItemContainsChildrenInShape flag that enables using optimizations of ItemClipsChildrenToShape without the overhead of enforcing the clip.

* Add a new optimization property to QGraphicsSceneDimitar Asenov2014-03-181-9/+73
| | | | | | | | | | | | | | | | | The minimumRenderSize is a qreal value that is used as a lower bound to determine what items are visible when a scene is rendered. If an item's view-transformed width or height are less than minimumRenderSize then this item is considered to insignificantly affect the final result and is not drawn. If the item clips its children to its shape they are automatically not drawn. This greatly reduces the drawing overhead for scenes with many items rendered in a zoomed out view. [ChangeLog][QtWidgets][QGraphicsScene] Added the minimumRenderSize property which can be used to speed up rendering by not painting items, smaller than a give size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This signal is emitted by QGraphicsScene whenever focus changes in the scene (i.e., when an item gains or loses input focus, or when focus passes from one item to another). You can connect to this signal if you need to keep track of when other items gain input focus. It is particularily useful for implementing virtual keyboards, input methods, and cursor items.

* | Make sure panels always gain focus when activated or tab is pressed.Andreas Aardal Hanssen2012-12-171-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes behavior, but I would argue it's a good change. If you create a panel and activate it (e.g., by simply showing it or reparenting it onto an already-visible item), you expect the panel to gain focus / which is sort of the whole point of activating it. Prior to this change, you had to have explicitly called setFocus() on one of the panel's children, which would give that item subfocus, for that item to auto- gain focus when the panel was activated. This change makes it more automatic. If the panel itself or any of the widgets in its focus chain can gain focus, they will gain focus when the panel is activated. So the new logic is - if the panel already has a focus item, so if someone explicitly set subfocus on an item before the panel is shown, that item gets focus. Otherwise, if the panel itself can gain focus (e.g., someone makes a line edit / text edit panel), it gains focus when activated. Otherwise, we search the focus chain until we find the first item that can gain focus. This last case is the file dialog case, where the dialog itself can't gain focus but typically the first item in the focus chain is the primary focus widget, such as the search field or the directory list view. The change also fixes this for the first Tab. If you clear focus on a panel, the user expects to be able to press Tab to regain focus. Prior to this change that didn't happen. Now, the panel or the first in the focus chain that can get focus gets focus on first tab.

|/ | | | | | | | | | | | | | | | | Add handling of the focus chain to QGraphicsItem::setFlags(), so that the focus chain is repaired (panels pop out of the chain and non-panels merge back in) when the ItemIsPanel flag is toggled. Add handling focus chain to QGraphicsWidgetPrivate::fixFocusChainBeforeReparenting for panels. Before this fix, you must enable the ItemIsPanel flag before adding the item as a child to a parent panel, and you lose focus when using the tab key to focus around a panel after it has been reparented into another panel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The capability flags indicate which information is valid in the touch points. Previously there was no way to tell if e.g. the value returned by pressure() is actually the value provided by the driver/device or it is just something bogus due to pressure not being supported. The points' flags return information about the individual touch points. One use case is to differentiate between touches made by finger and pen. Velocity, if available, is now also exposed. Each touch point can now contain an additional list of "raw" positions. These points are not reported individually but are taken into account in some way by the underlying device and drivers to generate the final, "accurate" touch point. In case the underlying drivers expose these additional positions, they are made available in the lists returned by the touch points' rawScreenPosition(). The raw positions are only available in screen coordinates to prevent wasting time with mapping from global positions in applications that do not use this data. Instead, apps can query the QWindow to which the touch event was sent via QTouchEvent::window() and can call mapFromGlobal() manually if they need local raw positions. The capability and device type information is now held in a new QTouchDevice class. Each touch event will contain only a pointer to one of the global QTouchDevice instances. On top of type and capability, the new class also contains a name which can be used to differentiate between multiple touch input devices (i.e. to tell from which one a given QTouchEvent originates from). The introduction of QTouchDevice has three implications: The QTouchEvent constructor and QWindowSystemInterface::handleTouchEvent need to be changed (to pass a QTouchDevice pointer instead of merely a device type value), and each platform or generic plug-in is now responsible for registering one or more devices using the new API QWindowSystemInterface::registerTouchDevice.
