◆ catchDanger

void MainWindow::catchDanger ( int type )

slot

catchDanger Slot function to handle a dangerous situation detected by the Safety class

Handles the detection of a danger signal.

Parameters

type	The type of danger detected

This function is called when a danger signal is detected based on the type parameter:

If type is 0, it indicates that the maximum allowed temperature has been exceeded.
If type is 1, it indicates that even though the MV output is at the maximum, the temperature change is less than the threshold.
