关于QTextEdit下ctrl+ENTER的实现(用于发送或其他功能) [复制链接]

#ifndef MYTEXTEDIT_H_
#define MYTEXTEDIT_H_


#include <QTextEdit>

class mytextedit:public QTextEdit
{
    Q_OBJECT
public:
    mytextedit(QWidget* parent=0);
    ~mytextedit();
signals:
    void Ctrl_Enter_Press();
protected:
    void keyPressEvent(QKeyEvent *event);
};

#endif

#include "mytextedit.h"
#include <QKeyEvent>

mytextedit::mytextedit(QWidget *parent)
    :QTextEdit(parent)
{
}

mytextedit::~mytextedit()
{
}

void mytextedit::keyPressEvent(QKeyEvent *event)
{
        if (event->modifiers() == Qt::ControlModifier && event->key() == Qt::Key_Return)
        {
            emit Ctrl_Enter_Press();
        }
        else
        QTextEdit::keyPressEvent(event);
}
