QWebView problem

[wirasto]

I try show a html file in webview, but I surprised because me always get a blank page.
I generate a html file with my function call htmlgenerate(). The file is created with successful, but I don't know why webview just give me a blank page. If I use firefox for display my html file, everything is fine.

This is my code for display

void Dialog::showHtml()
{
	htmlgenerate(); // save to QDir::tempPath ()+"/tahede.html"
 
	Viewer *lap0=new Viewer(this);
	lap0->setPage(QUrl(QDir::tempPath()+"/tahede.html"));
	lap0->reload();
	lap0->exec();
}

void Dialog::showHtml()
{
	htmlgenerate(); // save to QDir::tempPath ()+"/tahede.html"

	Viewer *lap0=new Viewer(this);
	lap0->setPage(QUrl(QDir::tempPath()+"/tahede.html"));
	lap0->reload();
	lap0->exec();
}

To copy to clipboard, switch view to plain text mode 

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}
 
 
void Viewer::reload()
{
    m_ui->web->reload();
    qDebug() << m_ui->web->url(); // result always QUrl( "about:blank" ) 
}

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}


void Viewer::reload()
{
    m_ui->web->reload();
    qDebug() << m_ui->web->url(); // result always QUrl( "about:blank" ) 
}

Btw, I always remove my html every close my application

void MainWindow::closeEvent(QCloseEvent *event)
{
    QFile::remove(QDir::tempPath()+"/tahede.html");
}

void MainWindow::closeEvent(QCloseEvent *event)
{
    QFile::remove(QDir::tempPath()+"/tahede.html");
}

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}

Perhaps, you should use load() instead of setUrl(), or you should call load() after calling setUrl()

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}

void Viewer::setPage(QUrl url)
{
	//web is QWebView
    m_ui->web->setUrl(url);
}

Perhaps you should change the name of your setPage(), because QWebView already has setPage().
