Qt键Pressevent输入 [英] Qt Key Pressevent Enter

问题描述

void LoginModle::keyPressEvent(QKeyEvent *event)
{
    qDebug() << event->key() << "\t" << Qt::Key_Enter << "\t" << QKeyEvent::Enter;
    if( event->key() == Qt::Key_Enter)
        OKButtonClicked();
    else
        QDialog::keyPressEvent(event);
}

这段代码非常简单，类LoginModle从QWidget继承.运行此代码，当我按 Enter 时，它将显示:

This code is very simple, class LoginModle inherits from QWidget. run this code and when I press Enter, it shows:

16777220     16777221    10

这意味着我在键盘上的 Enter 是16777220，但是在Qt中，它被定义为16777221.

It means that my Enter in keyboard is 16777220, but in Qt, it was defined as 16777221.

我的系统是基于Ubuntu 14.04的Elementary OS(Freya).

My system is Elementary OS (Freya), which is based on Ubuntu 14.04.

我的驱动程序是否有问题或只是程序的错误?

Is there something wrong with my driver or just the program's mistake ?

推荐答案

16777220(dec)= 1000004(hex)，因此根据 Wiki -Enter键在数字键盘中，您使用的键在Qt中称为返回键".

16777220(dec) = 1000004(hex), so according to this list, pressed key is "Return". Look at the Wiki - Enter key is in numeric keypad, key used by you is called in Qt "Return key".
