Detailed Description

Single Instance Interface to control the dispatch behaviour.

Use this object to create new queues, get one of the main or global queues.

When using this object from within a QRunnable executed on a queue you can also use it to get the queue you're running in.

For information about the Dispatch mechanism, please also see Apple's documentation on libDispatch.

Three priority classes used for the three standard global queues.

Enumerator:

static dispatch_time_t QDispatch::asDispatchTime ( const QTime & ) [static]

static QTime QDispatch::asQTime ( dispatch_time_t t ) [static]

Remarks:: Please be careful when using this converter as a QTime is tracking 24 hours max, whereas a dispatch_time_t can hold way more. This additional time will be cropped while converting.

static QDispatchQueue QDispatch::currentQueue ( ) [static]

Returns:: The queue the currently active runnable (or block) is executed in.

static QDispatchQueue QDispatch::globalQueue ( Priority p = DEFAULT ) [static]

Returns the global queue associated to the given Priority p.

Runnables submitted to these global concurrent queues may be executed concurrently with respect to each other.

static QDispatchQueue QDispatch::mainQueue ( ) [static]

Returns the main queue.

This is the queue running within the Qt Event Loop. Thus only items put on this queue can change the GUI.
