\title Qt WebBrowser
The Qt WebBrowser (codename \c{Roadtrip}) is a browser for embedded
devices developed using the capabilities of Qt and \l{Qt WebEngine}.
Using recent \l{Chromium Project}{Chromium}, it features up-to-date
HTML technologies behind a minimal but slick touch-friendly
user interface written in \l{Qt Quick}.
\image webbrowser.png
\section1 User Interface
The user interface of the browser is designed for embedded devices
using a touch screen. It uses flat icons and minimalistic transitions to
provide a contemporary look and feel.
All central actions are conveniently accessible in the menu bar at the
top. When the user scrolls down a page, the menu bar disappears to
leave more screen space for content. It appears again if
the user scrolls upwards.
\image menubar.png
The \uicontrol Back button (1) and \uicontrol Forward button (2) navigate
through the history of pages already visited.
The input bar (3) allows the user to type and edit URL's,
or search for text. It also allows to reload a page, or stop a page currently
loading.
Pages can be bookmarked with the \uicontrol Bookmark button (6),
the bookmarked pages are accessible through the \uicontrol Home button (4).
The \uicontrol Pages button (5) allows the user to manage the pages
currently opened. The \uicontrol Settings button (7) brings up a view of
the current settings.
\section2 Opening Pages
The input bar supports typing in either a full URL or a query
that is automatically passed to \l{Google}. Url suggestions of visited pages
matching the text are suggested during typing. The current text can be
cleared by pressing the \uicontrol Cancel button on the right.
\image inputhelp.png
When the user finishes editing, a blue line serves as a progress indicator
for the page currently loading. The loading can be stopped by pressing
the \uicontrol Cancel button. After the page finished loading
this button is replaced by a \uicontrol Reload button, that forces a reload
of the page when pressed.
\section2 Page Scrolling
The view of the page can be moved around by pressing and moving a finger.
\section2 Page Zooming
Zoom in or out a particular section of the page by pinching fingers.
\section2 Bookmark Management
Individual pages can be bookmarked by pressing the \uicontrol Bookmark
button. By pressing the same button again the page is removed from the
bookmarks.
The \uicontrol Home button lets the user browse the bookmarked pages
in a multi-page grid. Each page is represented by its name and icon,
if available.
\image bookmarks.png
\section2 Page Management
The \uicontrol Pages button enables the user to open new pages and to
switch between them using the Carousel UI pattern:
\image pageselection.png
The number of pages that can be opened simultaneously is intentionally
limited to 10.
\section2 User Settings
A settings page is available by pressing the \uicontrol Settings button.
The page contains options for enabling a \e {private browsing} mode
that does not leave traces in the history and cookies.
\image settings.png
\section2 Virtual Keyboard
The integrated \l{Qt Virtual Keyboard}
slides in whenever text input is required. It enables typing text in a
great variety of different languages.
\image virtualkeyboard.png
\section1 Features
Qt WebEngine leverages \l{Chromium Project}{Chromium} to provide
a state-of-the art, high performance HTML5 web engine.
\image html5test.png
\section2 Video and Audio
Chromium and therefore Qt WebEngine directly
integrate with OS services to access video and audio devices.
After the user acknowledges access to them, solutions using WebRTC, such as
video and audio conferencing, work out-of-the-box, provided that the
required codecs are available.
\section2 Location Information
Qt WebEngine uses \l {Qt Location} to provide pages with location
information. Again, the users have to explicitly give their consent to each
page attempting to access this information.
\section2 Fullscreen Mode
Videos can be played in fullscreen mode.
\section1 Developer Features
\section2 Developer Tools
Qt WebEngine supports remotely accessing the built-in Chromium Developer
Tools. This allows debugging and optimizing individual pages on the device.
For more information, see the \l{Qt WebEngine} documentation on
\l{Qt WebEngine Debugging and Profiling}{Debugging and Profiling}.
\section2 Simulation of Touch Input
While the Qt WebBrowser is optimized for touch devices,
it can also be tested on all the desktop operating systems.
Keyboard and mouse input works out of the box. Touch input
can be simulated by using several mouse buttons
while pressing the \c Ctrl key.
\section1 Platform Requirements
Qt WebBrowser requires the \l{Qt WebEngine},
\l{Qt Quick} and
\l{Qt Virtual Keyboard} modules in version 5.7 or
newer.
\image block-diagram.png
At minimum 1 GB of RAM is advised to provide a seamless experience
for different pages. Depending on the exact configuration and the
pages visited this can be further optimized.
Qt Quick and Qt WebEngine use OpenGL for rendering. Best performance
therefore requires dedicated graphics hardware with drivers supporting
OpenGL.
