Re: [Foxgui-users] FOX and Multithreading

[Selverian, J. <Joh...@sy...>]

I use something like this after I start my threads:




	firstLoop = true;
	anyThreadsRunning = false;
	while (true) 
	{
		totalRunsCompleted = numAcceptedRuns = 0.0;
		anyThreadsRunning = false;
		for ( FXint i = 0 ; i < totalNumCombiThreadsRunning ; i++ ) 
		{
			if ( comboRunsThread[i].running() ) {
				anyThreadsRunning = true;
			}
			totalRunsCompleted += comboRunsThread[i].getTotalRunsCompleted();
			numAcceptedRuns += comboRunsThread[i].getNumAcceptedRuns();
		}

		// if all threads are finished
		if ( !anyThreadsRunning ) {
			break;
		} else {
			if ( firstLoop ) {
				setButtons();
				firstLoop = false;
			}

			progressBar->setProgress((FXint) (totalRunsCompleted * 100.0 / largestNumRuns));
			tmpStr.format("%d", numAcceptedRuns);
			acceptedDesigns_LBL->setText(tmpStr);

			if ( getApp()->peekEvent() ) {
				getApp()->runWhileEvents();
			}
		}
	} // while (true)

Subject: [Foxgui-users] FOX and Multithreading

Hi,

I'm using FOX 1.6.

If I remember correctly, FOX functions must only be called from within the main thread. However, I want a worker thread to prepare some data which needs then to be displayed as soon as it's ready (and convenient for the main thread).

Can someone please hint me as to how data can safely be transported from a side thread to the main thread?


Thanks and
Regards
Martin
