The ctkCmdLineModuleFutureWatcher class provides enhanced monitoring of a ctkCmdLineModuleFuture using signals and slots.
This class enhances the standard QFutureWatcher class by adding the two signals outputDataReady() and errorDataReady(). These signals are fired whenever the watched future reports new output data (usually text written to the standard output channel) or new error data (usually text written to the standard error channel).
Use readPendingOutputData() or readPendingErrorData() to get the newly added data.
- Warning
- While you could use a QFutureWatcher<ctkCmdLineModuleResult> instance directly (and provide a ctkCmdLineModuleFuture via QFutureWatcher<ctkCmdLineModuleResult>::setFuture(future) by virtue of "slicing") this is discouraged. The reason is that a member variable of type QFutureWatcher<ctkCmdLineModuleResult> will have a different size, depending on the inclusion of the ctkCmdLineModuleFutureInterface.h header (this header provides a specialization of the QFutureInterface template which adds a data member). This can lead to subtle heap corruptions. Since the code compiles with or without the ctkCmdLindeModuleFutureInterface.h inclusion, you should always use ctkCmdLineModuleFutureWatcher when working with ctkCmdLineModuleFuture objects to avoid runtime heap corruptions.
