\enum QX11Info::PeekOption
\brief An enum to tune the behavior of QX11Info::peekEventQueue().
\value PeekDefault
Peek from the beginning of the buffered native event queue. A peeker
id is optional with PeekDefault. If a peeker id is provided to
peekEventQueue() when using PeekDefault, then peeking starts from
the beginning of the queue, not from the cached index; thus, this
can be used to manually reset a cached index to peek from the start
of the queue. When this operation completes, the associated index
will be updated to the new position in the queue.
\value PeekFromCachedIndex
QX11Info::peekEventQueue() can optimize the peeking algorithm by
skipping events that it already has seen in earlier calls to
peekEventQueue(). When control returns to the main event loop,
which causes the buffered native event queue to be flushed to Qt's
event queue, the cached indices are marked invalid and will be
reset on the next access. The same is true if the program
explicitly flushes the buffered native event queue by
QCoreApplication::processEvents().

\typedef QX11Info::PeekerCallback
Typedef for a pointer to a function with the following signature:

The \a event is a native XCB event.
The \a peekerData is a pointer to data, passed in via peekEventQueue().
Return \c true from this function to stop examining the buffered
native event queue or \c false to continue.
\note A non-capturing lambda can serve as a PeekerCallback.
*/
/*!
\brief Peek into the buffered XCB event queue.
You can call peekEventQueue() periodically, when your program is busy
performing a long-running operation, to peek into the buffered native
event queue. The more time the long-running operation blocks the
program from returning control to the main event loop, the more
events will accumulate in the buffered XCB event queue. Once control
returns to the main event loop these events will be flushed to Qt's
event queue, which is a separate event queue from the queue this
function is peeking into.
\note It is usually better to run CPU-intensive operations in a
non-GUI thread, instead of blocking the main event loop.
The buffered XCB event queue is populated from a non-GUI thread and
therefore might be ahead of the current GUI state. To handle native
events as they are processed by the GUI thread, see
QAbstractNativeEventFilter::nativeEventFilter().
The \a peeker is a callback function as documented in PeekerCallback.
The \a peekerData can be used to pass in arbitrary data to the \a
peeker callback.
The \a option is an enum that tunes the behavior of peekEventQueue().
The \a peekerId is used to track an index in the queue, for more
details see QX11Info::PeekOption. There can be several indices,
each tracked individually by a peeker id obtained via generatePeekerId().
This function returns \c true when the peeker has stopped the event
proccesing by returning \c true from the callback. If there were no
events in the buffered native event queue to peek at or all the
events have been processed by the peeker, this function returns \c
false.
