I am currently trying to develop a basic browser web in order to surf on a specific internet site using qt framework. I created a MyWindow class which inherits QWebView and reimplements createWindow function, this in order to handle the opening of potential pop-ups in a new browser window. It works well during "normal" navigation, but when I encounter links such as:
<a class="lien_default" href="javascript:popupChat2('foo.php?id=42250')">bar</a>
If linked page has a flash content, a new window is created but it is empty. Here is the code of popupChat2:
function popupChat2(page)
{fenetre=window.open(page,'chat','top=0, left=0, width=800, height=500, resizable=no, toolbar=no, scrollbars=no, status=no, menubar=no, titlebar=no, dependent=yes');}
I also tried to save locally linked page, and if I open it with a very simple qt browser web like this:
main.cpp
#include "mainwindow.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
mainwindow.cpp
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
QUrl url("file:///[url of the page locally saved with flash player content]");
ui->setupUi(this);
QWebSettings *settings = ui->webView->settings();
settings->setAttribute(QWebSettings::JavascriptEnabled, true);
settings->setAttribute(QWebSettings::PluginsEnabled, true);
settings->setAttribute(QWebSettings::AutoLoadImages, true);
settings->setAttribute(QWebSettings::JavaEnabled, false);
settings->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);
settings->setAttribute(QWebSettings::LocalContentCanAccessFileUrls,true);
ui->webView->load(url);
ui->webView->show();
}
MainWindow::~MainWindow()
{
delete ui;
}
It is correctly loaded. The following is the code of my createWindow function and the code of linked page with flash content:
MyWindow *MyWindow::createWindow(QWebPage::WebWindowType type)
{
Q_UNUSED(type);
MyWindow *webView = new MyWindow;
webView->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
webView->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
webView->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);
webView->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
webView->setAttribute(Qt::WA_DeleteOnClose, true);
QWebPage *newWeb = new QWebPage(webView);
newWeb->setNetworkAccessManager(page()->networkAccessManager());
webView->setPage(newWeb);
webView->show();
return webView;
}

You apply your QWebSettings on webView, but they are effectively stored in
webView->page().So when you do
webView->setPage(newWeb);you revert to default QWebSettings, including the needed QWebSettings::PluginsEnabled.In fact, you don't seem to need an extra QWebPage, just set your QNAM on the default one:
