Method Details

connect

public final QMetaObject.Connection connect(Object receiver,
 String method,
 Qt.ConnectionType ... type)

Connects the signal to a method in an object. Whenever it is emitted, the method will be invoked on the given object.

Parameters:

receiver - The object that owns the method

method - The signature of the method excluding return type and argument names, such as "setText(String)".

connectionType - One of the connection types defined in the Qt interface.

Throws:

QNoSuchSlotException - Raised if the method passed in the slot object was not found

RuntimeException - Raised if the signal object could not be successfully introspected or if the signatures of the signal and slot are incompatible.

disconnect

public final boolean disconnect(Object receiver,
 String method)

Disconnects the signal from a method in an object if the two were previously connected by a call to connect.

Parameters:

receiver - The object to which the signal is connected

method - The method in the receiver object to which the signal is connected

Returns:

true if the connection was successfully removed, otherwise false. The method will return false if the connection has not been previously established by a call to connect.

Throws:

QNoSuchSlotException - Raised if the method passed in the slot object was not found

disconnect

public final boolean disconnect(Object receiver)

Removes any connection from this signal to the specified receiving object

Parameters:

receiver - The object to which the signal has connections

Returns:

true if any connection was successfully removed, otherwise false. The method will return false if no connection has previously been establish to the receiver.

Removes the given connection from this signal.

Parameters:

connection - the connection to be removed

Returns:
