在连接信号与槽时，报错解决error: no matching member for call to 'connect'

由于信号被重载过，同名了，但是参数不一样，就会报错。

connect(sender, SIGNAL(func()), receiver, SLOT(func1()))
- matching connect member error callmatching connect member error matching function connect member matching function信号connect max_connect_errors error server-side processing connected error operationalerror connection unknown connection redis error read error successfully established connection connection internal fatal error error connecting openocd cannot
