Hi. Please help me with signals.<br><br>I am trying to migrate code from C++ to C#. This is an example from Qt (Qt/4.8.2/examples/animation/animatedtiles/main.cpp)<br>In C++ has the following code:<br><br>class Button : public QGraphicsWidget<br>{<br>...<br>signals:<br> void pressed();<br>...<br>}<br><br>Then a signal "pressed()" is passed as a parameter to the function rootState->addTransition<br><br>Button *ellipseButton = new Button(QPixmap(":/images/ellipse.png"), buttonParent);<br>QState *rootState = new QState;<br>QAbstractTransition *trans = rootState->addTransition(ellipseButton, SIGNAL(pressed()), ellipseState);<br><br>I can't understand how to write it to C#.<br><br>class Button: QGraphicsWidget<br>{<br>...<br>protected pressed() <-- ??? How to properly declare a signal?<br>...<br>}<br>At first I thought do not use signals, and instead use the C# events:<br>event EventHandler pressed;<br>But in any case, don't know that I
need to pass to the function :(<br>rootState->addTransition(ellipseButton, SIGNAL("<--??? What to write here?"), ellipseState);<br><br>Please help me with a problem.<br><br>With best regards<br>Alexandr Vodorez<br><br>_______________________________________________<br>Kde-bindings mailing list<br><a ymailto="mailto:Kde-bindings@kde.org" href="mailto:Kde-bindings@kde.org">Kde-bindings@kde.org</a><br><a href="https://mail.kde.org/mailman/listinfo/kde-bindings" target="_blank">https://mail.kde.org/mailman/listinfo/kde-bindings</a><br><br><br> </div> </div> </div></body></html>
