Is a compile-time error

CodePudding user response:

Warning is a warning, not an error, can need not ignore
The Event 'dwndropdown' always be overloaded.
Events' dwndropdown 'cannot be overloaded,

CodePudding user response:

refer to the second floor zhangyangziwo response:

warning is a warning, not wrong, don't have to listen to
The Event 'dwndropdown' always be overloaded.
Events' dwndropdown 'cannot be overloaded,

The Event 'dwndropdown' always be overloaded. If you want to solve, what should I do?

CodePudding user response:

Try to compile this code comments, if no problem, check the code, see the specific where there is a problem,

CodePudding user response:

Tip can't overload, means that in the event have on the parent class; Can't overloading on a subclass, that is to say on the subclass rewrite this event,

CodePudding user response:

My program also have this problem, draw lessons from 4th floor to
The statement notes, compile again, no alarm,
Return statement, compile again, no alarm

Is really amazing solution
