qt - How can I simulate user interaction (key press event) in Qt?

Question

I need to simulate "Enter" key event in Qt. How can I do this?

Answer 1

正确的答案可能是这样的：

QKeyEvent *event = new QKeyEvent ( QEvent::KeyPress, Qt::Key_Enter, Qt::NoModifier);
QCoreApplication::postEvent (receiver, event);

实际上没有匹配的函数来调用

QtKeyEvent::QtKeyEvent(Type type, int key)

但是还有：

QtKeyEvent::QtKeyEvent(Type type, int key, Qt::KeyboardModifiers modifiers)

Answer 2

QKeyEvent *event = new QKeyEvent ( QEvent::KeyPress, Qt::Key_Enter);
QCoreApplication::postEvent (receiver, event)
