2.1 PCB Dimension Requirements
On the right side of the form in Figure 1 is a QCalendarWidget component, which displays dates in the form of a calendar and can be used for date selection. QCalendarWidget has a signal selectionChanged (), which is transmitted after the date selected on the calendar changes. Create a slot function for this signal and write the following code:

D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:
