| 33 | + | Данный пример разработан для использования второго пакета доступа к Qt, описанного выше. | |
| 44 | 34 | ``` | |
| 35 | + | var | |
| 36 | + | app: QApplicationH; | |
| 37 | + | btn: QPushButtonH; | |
| 38 | + | begin | |
| 39 | + | // create static ( interfaced handled ) QApplicationH | |
| 40 | + | app := NewQApplicationH(ArgCount, ArgValues).get; | |
| 41 | + | // due to a bug in fpc 1.9.5 the WideString helper methods with default parameter are disabled | |
| 42 | + | //btn := NewQPushButtonH('Quit', nil).get; | |
| 43 | + | btn := NewQPushButtonH(qs('Quit').get, nil, nil).get; | |
| 44 | + | btn.setGeometry(100, 100, 300, 300); | |
| 45 | + | btn.show; | |
| 46 | + | // override the virtual eventFilter method of btn | |
| 47 | + | btn.OverrideHook.eventFilter := @TTest.MyEventFilter; | |
| 48 | + | // and install the btn as it's own eventFilter | |
| 49 | + | btn.installEventFilter(btn); | |
| 50 | + | // connect Qt signal to Qt slot | |
| 51 | + | QObjectH.connect(btn, SIGNAL('clicked()'), app, SLOT('quit()')); | |
| 52 | + | ... | |
| 53 | + | ``` | |

| 46 | 55 | Если вы знаете, как QT используется в C++, вы можете увидеть, что существует не так уж много различий. | |
