Qt WebView 怎么实现无边框拖动或者页面指定区域拖动

[Tz_Sword]

#ifndef WB_H
#define WB_H

#include <QWebView>
#include <QMouseEvent>
#include <QFrame>
#include <QWebFrame>

class Wb : public QWebView
{
	Q_OBJECT
public:
    Wb(QWidget * parent=0);
    ~Wb();
protected:
    virtual void mousePressEvent(QMouseEvent *event);
    virtual void mouseReleaseEvent(QMouseEvent *event);
	virtual void mouseMoveEvent(QMouseEvent *event);

private:
    QPoint offset;
    QPoint temp;

	QPoint move_point; //移动的距离
	bool mouse_press; //按下鼠标左键
};
#endif // WB_H

#include "wb.h"

Wb::Wb(QWidget * parent):QWebView(parent)
{
	setWindowFlags(Qt::FramelessWindowHint | Qt::Dialog);
	setAttribute(Qt::WA_TranslucentBackground);
	//初始化为未按下鼠标左键
	mouse_press = false;

}
Wb::~Wb()
{

}
void Wb::mousePressEvent(QMouseEvent *event)
{
	temp=event->pos();
	qDebug()<<"temp";
    qDebug()<<temp;
	if(temp.x()<100&&temp.y()<100){
		//只能是鼠标左键移动和改变大小
		if(event->button() == Qt::LeftButton) 
		{
			mouse_press = true;
		}
		//窗口移动距离
		move_point = event->globalPos() - pos(); 
	 }else{
		 this->setMouseTracking(true);
	 }
}
void Wb::mouseReleaseEvent(QMouseEvent *event)
{
	mouse_press = false;
}

void Wb::mouseMoveEvent(QMouseEvent *event)
{
	//移动窗口
	if(mouse_press)   
	{
		QPoint move_pos = event->globalPos();
		move(move_pos - move_point);
	}
}

#include "wb.h"
#include <QtWidgets/QApplication>

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
	
	Wb w;
	w.load(QUrl("http://www.baidu.com"));
	w.show();
	return a.exec();
}

页面可以拖动 但页面的标签 链接 按钮 不响应鼠标事件了


就是想 用Qt做个h5的壳子 里面嵌入页面，采用那些成熟的nodejs、Electron 与本地交互这块不熟悉
