This variable is an integer to allow for recursive calls to lockInGui() - without using a recursive mutex. See isPostingSyncEvent. - - RenderThread::isPostingSyncEvent: This variable is set in the render thread just - before the sync event is sent to the GUI thread. It is used to avoid deadlocks - in the case where render thread waits while waiting for GUI to pick up the sync - event and GUI thread gets a resizeEvent, the initial paintEvent or a grab. - When this happens, we use the - exhaustSyncEvent() function to do the sync right there and mark the coming - sync event to be discarded. There can only ever be one sync incoming. - - RenderThread::isRenderBlock: This variable is true when animations are not - running and the render thread has gone to sleep, waiting for more to do. - - RenderThread::isExternalUpdatePending: This variable is set to false when - a new render pass is started and to true in maybeUpdate(). It is an - indication to the render thread that another render pass needs to take - place, rather than the render thread going to sleep after completing its swap. - - RenderThread::doGrab: This variable is set by the grab() function and - tells the renderer to do a grab after rendering is complete and before - swapping happens. - - RenderThread::shouldExit: This variable is used to determine if the render - thread should do a nother pass. It is typically set as a result of show() - and unset as a result of hide() or during shutdown() - - RenderThread::hasExited: Used by the GUI thread to synchronize the shutdown - after shouldExit has been set to true. - */ - - -void QQuickRenderThreadSingleContextWindowManager::initialize() -{ - Q_ASSERT(m_rendered_windows.size());

QSGThreadedRenderLoop and + QSGRenderThread. All communication between the two is based on + event passing and we have a number of custom events. + + In this implementation, the render thread is never blocked and the + GUI thread will initiate a polishAndSync which will block and wait + for the render thread to pick it up and release the block only + after the render thread is done syncing. The reason for this + is: + + 1. Clear blocking paradigm. We only have one real "block" point + (polishAndSync()) and all blocking is initiated by GUI and picked + up by Render at specific times based on events. This makes the + execution deterministic. + + 2. Render does not have to interact with GUI. This is done so that + the render thread can run its own animation system which stays + alive even when the GUI thread is blocked doing i/o, object + instantiation, QPainter-painting or any other non-trivial task. + + --- + + The render loop is active while any window is exposed. All visible + windows are tracked, but only exposed windows are actually added to + the render thread and rendered. That means that if all windows are + obscured, we might end up cleaning up the SG and GL context (if all + windows have disabled persistency).

It doesn't however - directly proxy a list or model, instead a range of indexes from one or many lists can be - inserted into the compositor and then categorized and shuffled around and it will manage the - task of translating from an index in the combined space into an index in a particular list. - - Within a compositor indexes are categorized into groups where a group is a sub-set of the - total indexes referenced by the compositor, each with an address space ranging from 0 to - the number of indexes in the group - 1. Group memberships are independent of each other with - the one exception that items always retain the same order so if an index is moved within a - group, its position in other groups will change as well. - - The iterator classes encapsulate information about a specific position in a compositor group. - This includes a source list, the index of an item within that list and the groups that item - is a member of. The iterator for a specific position in a group can be retrieved with the - find() function and the addition and subtraction operators of the iterators can be used to - navigate to adjacent items in the same group. - - Items can be added to the compositor with the append() and insert() functions, group - membership can be changed with the setFlags() and clearFlags() functions, and the position - of items in the compositor can be changed with the move() function. Each of these functions - optionally returns a list of the changes made to indexes within each group which can then - be propagated to view so that it can correctly refresh its contents; e.g. 3 items - removed at index 6, and 5 items inserted at index 1. The notification changes are always - ordered from the start of the list to the end and accumulate, so if 5 items are removed at - index 4, one is skipped and then 3 move are removed, the changes returned are 5 items removed - at index 4, followed by 3 items removed at index 4. - - When the contents of a source list change, the mappings within the compositor can be updated - with the listItemsInserted(), listItemsRemoved(), listItemsMoved(), and listItemsChanged() - functions. Like the direct manipulation functions these too return a list of group indexes - affected by the change. If items are removed from a source list they are also removed from - any groups they belong to with the one exception being items belonging to the \l Cache group. - When items belonging to this group are removed the list, index, and other group membership - information are discarded but Cache membership is retained until explicitly removed. This - allows the cache index to be retained until cached resources for that item are actually - released. - - Internally the index mapping is stored as a list of Range objects, each has a list identifier, - a start index, a count, and a set of flags which represent group membership and some other - properties. The group index of a range is the sum of all preceding ranges that are members of - that group. To avoid the inefficiency of iterating over potentially all ranges when looking - for a specific index, each time a lookup is done the range and its indexes are cached and the - next lookup is done relative to this. This works out to near constant time in most relevant - use cases because successive index lookups are most frequently adjacent. The total number of - ranges is often quite small, which helps as well.
