Detailed Description

Private implementation of fwThread::Worker using boost::asio.

Member Function Documentation

fwThread::Worker::FutureType fwGuiQt::WorkerQt::getFuture ( )

virtual

Returns a std::shared_future associated with the execution of Worker's loop.

Warning

Calling getFuture() may be blocking if it is required by a specific implementation (for example, the Qt implementation).

Reimplemented from fwThread::Worker.

Definition at line 213 of file WorkerQt.cpp.

References SLM_ASSERT.

void fwGuiQt::WorkerQt::processTasks ( )

virtual

Processes all worker pending tasks for the calling thread until there are no more tasks to process. You can call this function occasionally when your program is busy performing a long operation.

Warning

WxWidgets version is not yet implemented.

Implements fwThread::Worker.

Definition at line 261 of file WorkerQt.cpp.

void fwGuiQt::WorkerQt::processTasks ( PeriodType  maxtime )

virtual

Processes worker pending tasks for the calling thread for maxtime milliseconds or until there are no more tasks to process. You can call this function occasionally when your program is busy performing a long operation.

Parameters

maxtime

milliseconds to process worker pending tasks.

Warning

Qt implementation processes all Qt and Worker pending events, be careful.

WxWidgets version is not yet implemented.

Implements fwThread::Worker.
