QT学习之全局热键

在网上收到的注册QT全局热键的方法，基本都不支持QT5，查了大量资料发现QT5不支持QAbstractEventDispatcher::EventFilter；参考资料进行了更改，使用如下：

代码：

使用方法：

#include "./sethotkey/qxtglobalshortcut.h"

    QxtGlobalShortcut* m_pHotKey;

//注册热键

void initHotKey()
{
    m_strHotKey = "Ctrl+H";
    m_pHotKey = new QxtGlobalShortcut(QKeySequence(m_strHotKey));
    connect(m_pHotKey, SIGNAL(activated()), this, SLOT(slotHotKeyEvent()));
}

//删除热键

void DeleteShortcut()
{
    m_pHotKey->setDisabled();

//
}

 

void slotHotKeyEvent

{

//do something

}
