Latest Flash Player for OS X not working with Qt 4.8.n applications.
After the latest Flash Player update, to version 11.8.800.94, Flash areas in QWebView and QGraphicsWebView objects stopped working in OS X. GUI is never shown, but sound can be heard.
This happens at least using x86 OS X compiled versions of Qt 4.8.2 and 4.8.5 together with both our cross platform application and the “fancybrowser” example included with Qt (with one additional statement to enable plugins).
Qt 5.1.0 work fine in OS X, Windows applications based on Qt 4.8.n work fine and if we downgrade the OS X Flash player to some earlier version, like 11.7.700.232 things work fine too.
None of the examples at this page work: http://www.adobe.com/devnet/flash/samples.html
Update!
When using the non working Flash plugin the invalidRect argument passed to NPN_InvalidateRect (in “npapi.cpp”) always have the dimension (0, 0, 2000, 2000). When using working Flash plugins the area varies depending on GUI updates and always have more sane values.
Has anyone else experienced this problem? Is there a solution?
Thanks in advance!

Qt 5.1 QWebView Mouse Clicks Work but not Touch Clicks, but both work in Qt 4.8 QWebView
Hi,
I made an Windows 7 application on a QWidget that has an embedded QWebView.
I originally made it for Qt 4.8, and ported it to Qt 5.1 recently.
In Qt 4.8, on a Windows 7 Touch device, mouse clicking and touching the screen both result as a mouse click.
However, on Qt 5.1, mouse clicking and touching the screen still have the same result in my Application except with the QWebView. In the QWebView, mouse clicks work fine, but touching only highlights the link but no click is done. Everywhere else in my Application, touching works the same as the mouse clicks.
Is there some setting I must set? Here is my code for setting up the QWebView embedded browser:
QWebView * embeddedBrowser = new QWebView(this);
embeddedBrowser->setGeometry(embeddedBrowserRect);
embeddedBrowser->setVisible(true);
embeddedBrowser->page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks);
embeddedBrowser->setAttribute(Qt::WA_AcceptTouchEvents);
embeddedBrowser->setAttribute(Qt::WA_InputMethodEnabled);
embeddedBrowser->setAttribute(Qt::WA_TouchPadAcceptSingleTouchEvents);
connect(embeddedBrowser, SIGNAL(linkClicked(QUrl)), this, SLOT(browserLinkClicked(QUrl)));
connect(embeddedBrowser, SIGNAL(loadProgress(int)), this, SLOT(browserLoadProgress(int)));
connect(embeddedBrowser, SIGNAL(selectionChanged()), this, SLOT(browserSelectionChanged()));
embeddedBrowser->setEnabled(true);
What am I missing? And thank you very much for any help. I really appreciate it,

Link - middle button click
I am trying to write a simple tab browser and everything is working ok but I have problem in implementing opening link in tab by clicking on it with the middle mouse button. I don’t know in what way I should check if link was clicked by left button or middle button?
What I have already tried:
I have set
webView->page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks);
Then I used linkClicked signal
connect(webView->page(), SIGNAL(linkClicked(QUrl)), this, SLOT(linkClickedSlot(QUrl)));
but in this slot I don’t know how to check what button was clicked. So I thought to reimplement mousePressEvent in QWebView:
void WebView::mousePressEvent(QMouseEvent *event)
{
//checking what mouse button was clicked (left, middle, right)
if(event->button() == Qt::LeftButton)
{
lastClickedMouseButton = 0;//left 0
}else if(event->button() == Qt::MidButton)
{
lastClickedMouseButton = 1;//middle 1
}else if(event->button() == Qt::RightButton)
{
lastClickedMouseButton = 2;//right 2
}
}
and then check lastClickedMouseButton value in linkClickedSlot
void Tab::linkClickedSlot(QUrl url)
{
if(webView->lastClickedMouseButton == 0)//left button
{
qDebug("left button clicked");
webView->setUrl(url);//opening clicked link in this page
}else if(webView->lastClickedMouseButton == 1)//middle button
{
qDebug("middle button clicked");
//creating new tab with clicked link
//will be added later
}else if(webView->lastClickedMouseButton == 2)//right button
{
qDebug("right button clicked");
}else
{
qDebug("unknown button clicked");
}
}
And it is more-less working – when I click once it is not working but it is working when I click fast few times… How should I check if the left or middle button was clicked in the correct way?

QWebView - jquery script problem
Hi,
I’m developping a simple HTML5 interface for an embedded system and for containers, i’ve decided to use iscroll4 plugin ( http://cubiq.org/iscroll-4 ) to animate a bit the scrolling.
The problem is that this plugin/script is not working. Also, I’m not receiving any errors on console if i’m enabling developing extras setting.
Also, i’ve tried to load directly this link : http://cubiq.org/dropbox/iscroll4/examples/simple/ in a QWebView object, but doesn’t work too.
Has anyone encountered this problem and knows a solution?
Thanks a lot!

QMimeData::setUrls() and setData() with custom data type works works incorrect(different) from JS-side.
Hello,
I have an issue with QMimeData.
It works well in Qt 4.7.4, but it works in another way in Qt 4.8, Qt 5.1 (Win7).
My application is custom QWebView that shows some WebPage.
I have added some code on DropEvent but the issue can be reproduced even using browser-project from example.
1. Open browser(5.1) / fancybrowser(4.8.4) / fancybrowser(4.7.4) from example folder
2. Open test-html page:
<html>
<body>
<input name="First" size="40" ondrop=droph(event) ondragover="return false;"/>
</body>
</html>
<scrip_t>
function droph(event)
{
alert(event.dataTransfer.getData('text/uri-list'));
alert(event.dataTransfer.getData('text/plain'));
//console.log('PoolName', event.dataTransfer.getData('PoolName'));
}
</scrip_t>
3. Drag’n‘Drop file(-s) on input area on webPage.
Result (alerts()):
4.7.4 libs will show you links to files that you droped (‘text/uri-list’)
4.8.4 & 5.1.0 will show some Chinese chars first(‘text/uri-list’) and after that correct paths(‘text/plain’).
Chinese chars is some kind of another(incorrect?) encoding of data.
The same behavior for custom Mime-data. If I use
byteArrPoolName.append("MyNameOfPool");
mimeData->setData("PoolName", byteArrPoolName);
and after that try to get it in JavaScript
event.dataTransfer.getData('PoolName');
It returns incorrect charachters the same as in Uri case.
Please, help me. Because It blocks my application in migration to newer version of Qt and WebKit.
Thanks in advance.

QNetworkReply and 302 Found code
Hi all,
I am developing an application that uses the Qt Webkit. I have this code :
void SignalHandler::ddlogin()
{
Manager = new QNetworkAccessManager();
QObject::connect(Manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(finished_login(QNetworkReply *)));
QNetworkRequest request;
request.setUrl(QUrl("http://ddunlimited.net/ucp.php?mode=login"));
request.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/x-www-form-urlencoded"));
request.setRawHeader("User-Agent", "Firefox/3.0.10");
QUrl params;
params.addQueryItem("username", *(Config->get_user_forum()) );
params.addQueryItem("password", *(Config->get_pass_forum()));
params.addQueryItem("redirect","index.php");
params.addQueryItem("login", "Login");
params.encodedQuery();
QNetworkReply *test = Manager->post(request,params.encodedQuery());
}
void SignalHandler::finished_login(QNetworkReply *reply)
{
QObject::disconnect(Manager, SIGNAL(finished(QNetworkReply *)),this,SLOT(finished_login(QNetworkReply *)));
QByteArray *temp = new QByteArray(reply->readAll());
QFile file("temp.html");
file.open(QIODevice::WriteOnly);
file.write(*temp);
file.close();
}
This code should make the login in forums based on phpbb3. It works for several forums, but it doesn’t work for a forum. The problem is that the reply->readAll() return an empty QByteArray. The same code works for others forum, and it returns the html page after the login.
I tried to debug the problem with a network analyzer and I saw that the server responds with the http response status code 302. It seems a sort of redirect, but I’m not sure. How can I handle this ? Is there a workaround ? Sorry for my english and sorry for my lack of experience.
Kind regards,
Stefano.

Qt application could be minimized only once in Mac
Overview:
The logic to minimize the application using ‘window()->setWindowState(Qt::WindowMinimized)’ is only working for the first time in Mac. Successive call to the same after maximizing the window does not have any action.
Steps to Reproduce:
A Qt application was created with a ‘minimizeScreen’ button which has the action to minimize the window using a call to “window()->setWindowState(Qt::WindowMinimized)” .
#include “mainwindow.h”
#include “ui_mainwindow.h”
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
connect(ui->minButton, SIGNAL), this, SLOT));
}
void MainWindow :: minimizeWindow()
{
window()->setWindowState(Qt::WindowMinimized);
}
[\code]
Actual Results:
The window minimizes for the first time. Successive call to minimize does not have any action.
Expected Results:
The window must be minimized every time when the user presses the ‘minimizeScreen’ button.
Build Date & Platform:
Tried with QT 5.0.2 and QT 5.0.1 . OS : MAC OSX 10.8.3

Getting a higher quality image from QWebPage
I’m creating an image capture utility to allow uses to download snapshots of the charts and graphs that our web application generates. I’ve used the Framecapture [qt-project.org] example application as a starting point.
It works well, but the image quality is too low for our needs. I need to be able to created higher resolution images.
My understanding from reading the QWebPage documentation [qt-project.org] is that I need to increase the pixel density ratio in the Viewports Attributes.
Unfortunately, I cannot figure out how to do that. Seems like I might need to do something with the X11 server that QWebPage talks to to get the Viewports Attributes, but I’m not a real expert in any of this stuff, so am having a hard time figuring it out.
Could somebody please give me some pointers?
The code that I’m using is basically like this:
QWebPage m_page;
m_page.mainFrame()->load(url);
m_page.mainFrame()->setScrollBarPolicy(Qt::Vertical, Qt::ScrollBarAlwaysOff);
m_page.mainFrame()->setScrollBarPolicy(Qt::Horizontal, Qt::ScrollBarAlwaysOff);
m_page.setViewportSize(1200,800);
QImage image(m_page.mainFrame()->contentsSize(), QImage::Format_ARGB32_Premultiplied);
image.fill(Qt::transparent);
QPainter painter(&image);
painter.setRenderHint(QPainter::Antialiasing, true);
painter.setRenderHint(QPainter::TextAntialiasing, true);
painter.setRenderHint(QPainter::SmoothPixmapTransform, true);
m_page.mainFrame()->documentElement().render(&painter);
painter.end();
image.save(fileName);
