\title Qt for WinRT
\brief Provides insight into Qt's WinRT port and how to use it.
\ingroup supportedplatform
Qt for WinRT allows you to run Qt applications on devices supporting the
Windows Store App APIs. This includes Modern UI applications in Windows 8.1
and up, as well as devices running Windows RT 8.1 and Windows Phone 8.1
and up.
Microsoft introduced a new design paradigm with the Windows 8 Modern UI. A
core part of this new approach is Windows Runtime (WinRT) that supports
development using different programming languages, such as C++/CX (component
extensions), C# VB.NET, or JavaScript. The Qt port uses the C++
capabilities. While WinRT supports the component extensions internally, they
are not used inside Qt and you do not need to use them. WinRT applications
run in a sandboxed environment for security reasons and support different
architectures, such as ARM and x86.
\section1 Requirements
Development for Windows Runtime requires a Microsoft Windows development host.
The minimum version supported is Windows 8.1.
Depending on your device target you will need the following tools provided
by Microsoft to be installed:
\table
\header
\li Device Target
\li Environment
\row
\li Windows 8.1 Modern UI
\li Visual Studio 2013 for Windows
\row
\li Windows RT
\li Visual Studio 2013 for Windows
\row
\li Windows Phone 8.1
\li Visual Studio 2013 for Windows Phone
\row
\li Windows 10
\li Visual Studio 2015
\endtable
If you are targeting a remote device, please follow all instructions by
Visual Studio to set it up correctly.
If you are targeting an emulator for Windows Phone, Windows 8.1 Pro is
required by Microsoft to launch the emulator itself.
\section1 Getting Started
\section2 Building Applications
You can develop applications for WinRT just as any other Qt applications.
Use your favorite editor or IDE (such as Qt Creator) and create your
application or load a Qt example. Then run \c qmake and \c {nmake/jom} to
build your application.
\section3 Building Applications with Visual Studio
To launch your project with Visual Studio a corresponding project needs to
be created. \c qmake supports converting a \c .pro project into Visual
Studio format by passing the parameters \c -tp vc.
\code
qmake -tp vc <your project>.pro
\endcode
Be aware of using the correct match of \c qmake and Visual Studio. As the
Visual Studio format is generic, it does not return an immediate error if
for instance you open a Windows Phone project inside Visual Studio
for Windows.
This creates a project which supports building applications and running them
with Visual Studio. It does not embed Qt libraries into the package and
requires you to add them manually. For this purpose, the command line
tool \l{The Windows Deployment Tool}{windeployqt} has been included in the installed package. To
enable automatic parsing of dependencies and adding the libraries and
dependencies into the application package, create the project with the
following options:
\code
qmake -tp vc <your project>.pro "CONFIG+=windeployqt"
\endcode
\section3 Building Applications with Qt Creator
You will not need to do any conversion to open your project in Qt Creator.
Please follow the generic instructions on how to open and build a project.
Qt Creator deploys your application on the WinRT device, if the
device is detected by the PC.
\note Remote PCs, such as the Surface, are not yet supported for deployment by Creator.
\section1 Building from Source
We assume that you have cloned the Qt 5 repositories (or obtained
the Qt sources elsewhere) and followed the platform-independent
requirements for building Qt. The process of building Qt is found
in the \l{Building Qt Sources} page.
Qt for WinRT is always built as a cross-build, because tools, such as qmake,
are built as desktop applications. For compiling those, a desktop development
environment is required. If you have installed Visual Studio 2013 for Windows,
this will only create binaries for WinRT. You will need Visual Studio for
Windows Desktop as well to create those desktop tools.
Please make sure to use an x86 command prompt (either use the \e {VS x86 Native
Tools Command Prompt} or call \e vcvarsall.bat without any parameter or with \c x86)
for every WinRT/Windows Phone build. While the toolchain which is used for the
target is set automatically, the command prompt decides what will be used for the
host tools like \e qmake or \e moc. Building these tools might fail if another
command prompt is used.
The WinRT mkspec format is \c {<platform>-<architecture>-<toolchain>}
where \e platform can be \c winrt or \c winphone and architecture can be
\c arm, \c x86, or \c x64. The following is an example of building qtbase
for WinRT:
\code
> ./configure -xplatform winrt-x64-msvc2013 -release
> nmake/jom
\endcode
\section1 Running Applications from Command Line
WinRT applications must be packaged (including all dependencies) and
installed or registered with the application service in order to be
launched. \l{winrtrunner}{The WinRT Runner Tool} can be used to
launch these applications from the command line.
\section2 Package Content
Package content
consists of the application executable and its dependencies, as for every
Windows application. The dependencies are the needed (Qt)
libraries and plugins. Note that Qt plugins have to be put into a folder
named after their category (platforms, imageformats, and so on) without
using a \c plugins folder as root. For more information, see
\l{Qt for Windows - Deployment}.
As WinRT applications are run in a sandboxed environment, setting
the path variable to point to the files required will not work.
The \l{The Windows Deployment Tool}{windeployqt} convenience tool looks up
the application's dependencies
and copies Qt libraries and plugins to the appropriate directories, as
necessary.
Because all resources are placed to one directory, you can register the
directory using an XML file (AppxManifest.xml) and Windows Powershell. The reference
for these manifest files can be found
\l{http://msdn.microsoft.com/en-us/library/windows/apps/br211473.aspx}{here}.
The target processor architecture must be specified (as opposed to the default,
'neutral').
As soon as these requirements are met, change into your \e packaged directory in
PowerShell and call:
\code
> Add-AppxPackage -Register AppxManifest.xml
\endcode
\note \l{winrtrunner}{The WinRT Runner Tool} can perform the same operation with the --install option.
If that worked, you should be able to find your application in Windows 8.1's
start screen. To remove your application, use Windows' built-in way to
uninstall applications (right-click or tap and hold the application and
choose \c{Uninstall}).
\note \l{winrtrunner}{The WinRT Runner Tool} can perform the same operation with the --remove option.
\section2 WinRT Runner Tool
\target winrtrunner
The WinRT Runner Tool can be found in QTDIR/bin/winrtrunner. It is
intended to aid in the deployment, launching, and debugging of Qt for WinRT
applications. It can be used from the command line, or invoked by the IDE.
\badcode
Usage: winrtrunner.exe [options] package [arguments]
winrtrunner installs, runs, and collects test results for packages made with Qt.
Options:
--test Installs, starts, collects output, stops (if
needed), and uninstalls the package. This is
the default action of winrtrunner.
--start Starts the package. The package is installed
if it is not already installed. Pass
--install to force reinstallation.
--debug <debugger> Starts the package with the debugger
attached. The package is installed if it is
not already installed. Pass --install to
force reinstallation.
--debugger-arguments <arguments> Sets the arguments to be passed to the
debugger when --debug is used. If no
debugger was provided, this option is ignored.
--suspend Suspends a running package. When combined
with --stop or --test, the app will be
suspended before being terminated.
--stop Terminates a running package. Can be be
combined with --start and --suspend.
--wait <seconds> If the package is running, waits the given
number of seconds before continuing to the
next task. Passing 0 causes the runner to
wait indefinitely.
--install (Re)installs the package.
--remove Uninstalls the package.
--device <name|index> Specifies the device to target as a device
name or index. Use --list-devices to find
available devices. The default device is the
first device found for the active run
profile.
--profile <name> Forces a particular run profile.
--list-devices Lists the available devices (for use with
--device).
--verbose <level> Sets the verbosity level of the message output
(0 - silent, 1 - info, 2 - debug). Defaults
to 1.
--ignore-errors Always exits with code 0, regardless of the
error state.
-?, -h, --help Displays this help.
Arguments:
package [arguments] The executable or package manifest to act
upon. Arguments after the package name will
be passed to the application when it starts.
