Destructs an QtSignalCollector object.
Member Function Documentation
| void niftk::QtSignalCollector::AddListener | ( | QtSignalListener * | listener | ) |
Adds a listener that will get notified of the Qt signals that this object is connected to.
| void niftk::QtSignalCollector::Connect | ( | const QObject * | object, |
| const char * | signal = 0 |
||
| ) |
Connects this object to the signals of the given object. The current object will collect the given signals of that object.
| const QtSignalCollector::Signals & niftk::QtSignalCollector::GetSignals | ( | ) | const |
Gets the signals collected by this object.
| QtSignalCollector::Signals niftk::QtSignalCollector::GetSignals | ( | const char * | signal | ) | const |
Returns a set of the collected Qt signals that are of the given type.
| QtSignalCollector::Signals niftk::QtSignalCollector::GetSignals | ( | const QObject * | object, |
| const char * | signal = 0 |
||
| ) | const |
Returns a set of the collected Qt signals that are sent from the given object, and are of the given type.
| niftk::QtSignalCollector::mitkClassMacroItkParent | ( | QtSignalCollector | , |
| QObject | |||
| ) |
|
overrideprotectedvirtual |
Adds the object-signal pair to the list of collected signals.
Create a copy of the event as a newly allocated object.
Implements niftk::QtSignalListener.
|
overrideprotectedvirtual |
Prints the collected signals to the given stream or to the standard output if no stream is given.
Note that the SIGNAL macro inserted a '2' character before the signature of the signal. We do not want to print that, that is why we step the pointer by 1 (constData() + 1).
| void niftk::QtSignalCollector::RemoveListener | ( | QtSignalListener * | listener | ) |
Removes a listener. The listener will not get notified about the Qt signals observed by the current object, any more.
