Username or E-mail. It has become increasingly difficult to access Silverlight content in the browser with every passing year. In fact, the option to even enable Silverlight in Chrome was removed by Google in September of Yet some Silverlight content remains on the internet. But not a complete loss. It is still possible to use Silverlight in Chrome on Windows 10 with a free extension.

Until which time it becomes impossible to use these technologies, holdouts can still view Silverlight content within the Chrome wrapper. The extension uses the Internet Explorer rendering engine so you can view Silverlight content. Launch Google Chrome. A dialog will display asking you if you want to Add IE Tabaccompanied by a list of functions it can perform. Click the Add extension button. Click the icon to open an IE Tab.

In the IE Tab, input the web address of the page that contains Silverlight content. Your choice on Windows 10 to view Silverlight content is… you guessed it Internet Explorer.

Tags Chrome Google Silverlight Tweets by techhelpkb.So if you ask current market trend in browser technology then keep in mind browser should be compatible to HTML5 specifications.

For application layer Qt is one of the most popular platform. Again there are different Qt versions like Morty supports Qt 5. So ultimately we can not pick any Qt version from your choice like 5. It should be compatible with your BSP version. So here why we are discussing processor, BSP and all that stuff.

You might be saying i am interested in application layer and i want to write or port simple HTML5 compatible browser then why should i care of BSP version? Yes its important that what we choose and what could be the suitable for my application which i expect bug free and of production quality. In addition to the more common usage of Qt on the desktop, Qt is also great for developing apps to run on embedded linux devices. Instead of painting via X11, Qt when built for embedded Linux draw directly onto the framebuffer.

So when we choose Qt then we have many browser applications which is developed based on Qt.

Here i am considering production level browser applications and not browser like Qt demo browser. Basically Qt supports two backends, webkit and webengine. So most of Qt based browser supports both backend. So either you can compile your browser source for QtWebkit or QtWebengine.

So which backend is most suitable for your application? This comparison is mainly between QtWebkit and QtWebengine so we are not going to compare any above mentioned browser. In fact all above browsers are good and continuously doing improvement in browser features but they depends on Qt backend so if you see any problem with above browsers which might be problem of QtWebkit or QtWebengine.

So again back end is very important. As mentioned earlier, Webengine based on chromium so we get massive score here. If we compare with Google Chrome on PC i get out then you can realize how webengine score is much much better for embedded platform.August What can I do?

So what's special here? Why webkit? It's the most widely used, most widely deployed and easy to integrate web content rendering engine. Even the chrome's blink rendering engine is webkit based. It's open source too! Why Qt? The Qt toolkit is open source, versatile and easy to integrate in almost any GUI application. Qt widget style is highly configurable and pleasant looking too. Let's start, the main focus is being lightweight, but it should provide the basic features of a web browser.

Qupzilla started just as a research project, initially coded in Python PyQt now available in both Qt 4 and Qt 5. It's a fully featured browser with fast browsing and lots of settings to play around. Qupzilla is lightweight, but the web browsing speed is not that great, and forget about playing YouTube. On the other hand, Falkon is a little heavy, but performance is very close to Firefox or Google Chrome.

Both of them are capable of loading some extensions too. Otter browser is the complete Qt 5 rewrite of classic opera browser. Otter browser aims to be user friendly and respects user privacy.

The latest version could be built using QtWebEngine as rendering engine backend. And I've to say, it's currently beating Falkon in terms of features. It can import opera session, opera bookmarks and opera notes. It offers fast browsing experience and starts amazingly fast. Official website otter-browser. You can also change otter browser's appearance with Qt5ct.

Official website github. Slimboat is a cross platform freeware web browser, not an open source software, available as precompiled binaries. It's based on Qt 4 and Webkit with small memory usage. Now It's outdated, the project updated to slimjet, which is based on blink rendering engine. It is highly configurable and very lightweight on system resources. It's simply amazing, download it and find more about it here.

You could use those lightweight webkit based browsers as simple HTML viewer, all of them also supports mhtml web archive. Another distinct advantage is they starts very fast compared to other browsers like Chromium or Firefox. Suggestions are always welcome, please let us know about your thoughts on those Qt browser.

Don't forget to share this with friends! Used to run Qupzilla up to version 1.The web content can be opened in new tabs or separate windows. HTTP and proxy authentication can be used for accessing web pages. To run the example from Qt Creatoropen the Welcome mode and select the example from Examples.

For more information, visit Building and Running an Example. This example supports multiple main windows that are owned by a Browser object. This class also owns the DownloadManagerWidget and could be used for further functionality, such as bookmarks and history managers. In main. If no arguments are passed on the command line, we open the Qt Homepage :. The BrowserWindow constructor initializes all the necessary user interface related objects.

The TabWidget contains one or several WebView instances as tabs, and delegates it's signals and slots to the currently selected one:. First, we create the WebView with the necessary methods and signals:. If the render process is terminated, we display a QMessageBox with an error code, and then we reload the page:.

The loaded page might want to create windows of the type QWebEnginePage::WebWindowTypefor example, when a JavaScript program requests to open a document in a new window or dialog. This is handled by overriding QWebView::createWindow :. We add a menu item to the context menu, so that users can right-click to have an inspector opened in a new window.

We also check if the QWebEnginePage::ViewSource action is in the menu, because if it's not we have to add a separator as well. In all the cases above, we display the appropriate dialog to the user.

In case of authentication, we need to set the correct credential values on the QAuthenticator object:. In case of SSL errors, we just need to return a boolean value indicating whether the certificate should be ignored. This section describes the workflow for opening a new page. The setUrl method of WebView just forwards the url to the associated WebPagewhich in turn starts the downloading of the page's content in the background.

Private browsingincognito modeor off-the-record mode is a feature of many browsers where normally persistent data, such as cookies, the HTTP cache, or browsing history, is kept only in memory, leaving no trace on disk. In this example we will implement private browsing on the window level with tabs in one window all in either normal or private mode. Alternatively we could implement private browsing on the tab-level, with some tabs in a window in normal mode, others in private mode. Implementing private browsing is quite easy using Qt WebEngine.

In the example this new profile is owned by the Browser object:. Required profile for private browsing is created together with its first window. The default constructor for QWebEngineProfile already puts it in off-the-record mode. All that is left to do is to pass the appropriate profile down to the appropriate QWebEnginePage objects. The Browser object will hand to each new BrowserWindow either the global default profile see QWebEngineProfile::defaultProfile or one shared off-the-record profile instance:.

Downloads are associated with a QWebEngineProfile. This method prompts the user for a file name with a pre-filled suggestion and starts the download unless the user cancels the Save As dialog :. The QWebEngineDownloadItem object will periodically emit the downloadProgress signal to notify potential observers of the download progress and the stateChanged signal when the download is finished or when an error occurs.A ListView -based item is used to display a list of recipe names.

Clicking on a name causes the web view to load the respective recipe page.

The overall appearance of the application is provided by the Qt Quick Controls 2 items, which have their active style set to the Material style. To run the example from Qt Creatoropen the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example. In main. We set the default Qt Quick Controls 2 style to the Material style, so we do not have to specify it for each new item we add.

The value will be used in the main QML code to determine the window size. In the main. We also set up the size of the window depending on its primary orientation as well as the platform, so that the application is usable on both desktop and embedded platforms.

On desktop, the size is constrained by a minimum of x pixels up to the maximum size that the screen supports. The default window size is pixels wide and pixels high in landscape orientation. On embedded devices, the window will occupy the whole screen. Next, we add a RowLayout item so we can divide the window into two parts: one being a custom RecipeList item containing the recipe titles, and the other being the WebEngineViewwhich shows the recipe details.

The spacing is set to zero so the items are positioned directly next to each other. The RecipeList item has a few attached Layout propertiesin order to scale the item to a maximum of one third of the layout width.

We give the item focus, so that the keyboard can be used to navigate the recipes, in addition to using mouse and touch. The WebEngineView has similar layout properties, to make it occupy two thirds of the layout width.

This allows the user to continue navigating through the recipes using the keyboard. We also disable the default context menu by accepting the ContextMenuRequest.

When the application starts, instead of directly showing the WebEngineViewwe show a placeholder Rectangle with a BusyIndicator to provide a nicer user experience while the application is loading. Once the first page in the view is loaded, we start a Timer that will hide the placeholder and show the actual page. The delay provides more time for the recipe images to load, so that when the view is shown, the page is completely rendered.

The timer also shows a help ToolTip that informs the user on how to navigate the recipes. Let's see what the RecipeList item looks like from the inside.

The root item is a FocusScope to allow transferring focus to the child ListView whenever the root item receives focus. We also declare a custom recipeSelected signal, which will be emitted when the current item of the ListView changes. Again, we set the spacing to zero and make sure the layout occupies the whole space of the parent item. Inside the layout there is a styled ToolBar item, with a Label inside of it serving as the ListView header. The second item inside the layout is a ListViewwhose contents will fill the remaining space in the layout.

We set clip to true, so that the delegates that are scrolled up are not seen under the ToolBar item. We set focus to true, so the ListView gains focus when the FocusScope does. We add a vertical scroll bar, so the user can scroll through the recipes if the window size is small.

We also specify the recipe model to be used by the ListView as described later in this topic.

We have an ItemDelegate set as the ListView delegate, which displays the recipe title. The contentItem is a Text item, customized with a few properties to adjust the visual appearance and position of the text.

We create a binding to the current delegate's model URL, so we can access the respective URL outside the delegate itself.A ListView -based item is used to display a list of recipe names.
