如何用QWebview打开本地的网页文件

[Fan小凡]

如何使用QWebView打开本地的网页文件，我使用的是下面这种方面
QUrl url = QUrl::fromUserInput(filename);
ui->webView->load(url);

不知为什么他会不停的打开窗口，能帮我解决一下这个问题吗？提前谢谢了！！1

可能是你循环调用上面贴的这部分代码了吧

[Fan小凡]

信号和槽的连接
QObject::connect(ui->openAction,SIGNAL(triggered()),this,SLOT(openHtmlSlot()));

槽的实现
void MainWindow::openHtmlSlot()
{
QString filename=QFileDialog::getOpenFileName(this,tr("打开文件..."),QString(),tr("网页文件 (*.htm *.mht *.html);;AllFiles(*.*)"));

if (!filename.isEmpty())
{
ui->webView->load(QUrl::fromUserInput(filename));

QString curFile = QFileInfo(filename).canonicalFilePath(); //获得文件的标准路径
this->setWindowTitle(curFile+" - WebView");

this->statusLabel->setText("");

}
}

我是这样做的没有用到循环呀！！！！

QObject::connect(ui->webView,SIGNAL(urlChanged(QUrl)),this,SLOT(setUrlSlot(QUrl)));

void MainWindow::setUrlSlot(QUrl url)
{
if(url.toString().contains(".html") || url.toString().contains(".htm"))
{
MainWindow *other =new MainWindow;
other->addressComboBox->addItem(url.toString());
other->addressComboBox->setCurrentIndex(other->addressComboBox->count()-1);
other->ui->webView->load(url);

other->show();
}
else
{
this->addressComboBox->addItem(url.toString());
this->addressComboBox->setCurrentIndex(this->addressComboBox->count()-1);
this->statusLabel->setText(url.toString());
this->statusProgressBar->show();
}
}

它的改变也应该会影响到这里吧！我看了好几遍代码了，Qt自带的例子里的代码我也看了，好像就是这样调用的，为什么它的就没问题呀！！！能帮我一下，再次谢谢了！！！！！
