Function Documentation

QmitkRunAsyncBlocking() [1/2]

template<typename T >

T QmitkRunAsyncBlocking	(	const QString &	title,
		const QString &	label,
		std::function< T()>	task
	)

Runs a long task in a background thread while keeping the UI responsive.

The function blocks until the task finishes, using a QEventLoop to process events and prevent the UI from freezing.

While the task is running, a QProgressDialog is shown with a delay of 250ms.

Exceptions are caught in the background thread and rethrown in the calling thread.
