如何在Qt中模拟用户交互(按键事件)？

Question

我需要在Qt中模拟"输入"键事件.我怎样才能做到这一点？

Answer 1

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

Answer 2

正确答案可能是这样的:

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)
