This update fixes:
- Compilation failure caused by template parameter error.
The software uses a syntax similar to Qt signal slots (but does not require moc), and provides developers with the following modules and functions:
*) GObject class; signal transmitters and signal receivers need to inherit this GObject class.
*) GSignal class; used to define signals and transmit signals;
*) GObject::connect function; developers use this function to connect the transmitter's signal to the receiver's slot function. After the connection is successful, the transmitter sends a signal, and the receiver's slot function will be called.
*) GObject::disconnect function; the developer uses this function to disconnect the transmitter's signal from the receiver's slot function. After the connection is disconnected, when the transmitter sends a signal, the receiver's slot function will not be called.
