Method Summary

void	connect(java.lang.Object receiver, java.lang.String method) Creates an auto-connection from this signal to the specified object and method.
void	connect(java.lang.Object receiver, java.lang.String method, Qt.ConnectionType type) Connects the signal to a method in an object.
void	connect(QSignalEmitter.AbstractSignal signalOut) Creates an auto connection from this signal to another.
void	connect(QSignalEmitter.AbstractSignal signalOut, Qt.ConnectionType type) Creates a connection from this signal to another.
boolean	disconnect() Removes all connections from this signal.
boolean	disconnect(java.lang.Object receiver) Removes any connection from this signal to the specified receiving object
boolean	disconnect(java.lang.Object receiver, java.lang.String method) Disconnects the signal from a method in an object if the two were previously connected by a call to connect.
boolean	disconnect(QSignalEmitter.AbstractSignal signalOut) Disconnects a signal from another signal if the two were previously connected by a call to connect.

Method Detail

connect

public final void connect(java.lang.Object receiver,
                          java.lang.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)".

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

Throws:

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

java.lang.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(java.lang.Object receiver,
                                java.lang.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(java.lang.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.

QSignalEmitter.AbstractSignal.disconnect(Object, String)

disconnect

public final boolean disconnect()

Removes all connections from this signal.

Returns:

True if the disconnection was successful.

See Also:

QSignalEmitter.AbstractSignal.disconnect(Object, String)

connect

public final void connect(java.lang.Object receiver,
                          java.lang.String method)

Creates an auto-connection from this signal to the specified object and method.

Parameters:

receiver - The object that owns the method

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

See Also:

QSignalEmitter.AbstractSignal.connect(Object, String, com.trolltech.qt.core.Qt.ConnectionType)

connect

public final void connect(QSignalEmitter.AbstractSignal signalOut)

Creates an auto connection from this signal to another. Whenever this signal is emitted, it will cause the second signal to be emitted as well.

Parameters:

signalOut - The second signal. This will be emitted whenever this signal is emitted.

Throws:

java.lang.RuntimeException - Raised if either of the signal objects could not be successfully be introspected or if their signatures are incompatible.

connect

public final void connect(QSignalEmitter.AbstractSignal signalOut,
                          Qt.ConnectionType type)

Creates a connection from this signal to another. Whenever this signal is emitted, it will cause the second signal to be emitted as well.

Parameters:

signalOut - The second signal. This will be emitted whenever this signal is emitted.

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

Throws:

java.lang.RuntimeException - Raised if either of the signal objects could not be successfully be introspected or if their signatures are incompatible.

disconnect

public final boolean disconnect(QSignalEmitter.AbstractSignal signalOut)

Disconnects a signal from another signal if the two were previously connected by a call to connect. A call to this function will assure that the emission of the first signal will not cause the emission of the second.

Parameters:

signalOut - The second signal.

Returns:

true if the two signals were successfully disconnected, or false otherwise.
