问题描述

如何生成KeyEvent?

How can I generate a KeyEvent?

我必须在Keys.onPressed&上显示功能我的虚拟键盘生成的事件.

I have to show functionality on Keys.onPressed & events generated from my virtual keyboard.

那么当我生成虚拟键盘事件时，我可以假冒生成键事件吗?

So can I fake generate key Events when my Virtual Keyboard events are generated?

我只能找到如何从Qt向QML发送KeyEvent，但是我想从QML发出信号.

I could only find how to sendKeyEvents to QML from Qt, but I want to signal it from QML.

推荐答案

您不能直接在QML中使用.

You can't directly in QML.

您可以做的是向您的QML虚拟键盘公开一个自定义的Qt对象，该对象会在您需要时发出键信号(例如，通过调用方法YourCustomKeySignalGenerator::pressKey(YourKeyEnum pressedKey))

What you can do is expose to your QML Virtual keyboard a custom Qt object that emits key signals when you want (e.g. by calling a method YourCustomKeySignalGenerator::pressKey(YourKeyEnum pressedKey) )
