Qt for WinRT allows you to run Qt applications on devices supporting the Windows Store App APIs. This covers Modern UI applications on Windows 10, Windows 10 Mobile and Windows 10 IoT.
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.
Development for Windows Runtime requires a Microsoft Windows development host. The minimum version supported is Windows 10.
Depending on your device target you will need the following tools provided by Microsoft to be installed:
| Device Target | Environment |
|---|---|
| Windows 10 Mobile | Visual Studio 2015 |
| Windows 10 Desktop | Visual Studio 2015 |
| Windows 10 IoT | Visual Studio 2015 |
| XBox One | Visual Studio 2015 |
If you are targeting a remote device, please follow all instructions by Visual Studio to set it up correctly.
As WinRT applications run in a sandboxed environment, some restrictions should be taken into account when considering porting or writing cross-platform applications:
QT_NO_PROCESS
being defined) as no subprocesses can be launched.
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
qmake
and
nmake/jom
to build your application.
To launch your project with Visual Studio a corresponding project needs to be created.
qmake
supports converting a
.pro
project into Visual Studio format by passing the parameters
-tp
vc.
qmake -tp vc <your project>.pro
Be aware of using the correct match of
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 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:
qmake -tp vc <your project>.pro "CONFIG+=windeployqt"
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.
注意： Remote PCs, such as the Surface, are not yet supported for deployment by Creator.
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 构建 Qt 源 页面。
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
VS x86 Native Tools Command Prompt
or call
vcvarsall.bat
without any parameter or with
x86
) for every
WinRT
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
qmake
or
moc
. Building these tools might fail if another command prompt is used.
The
WinRT
mkspec format is
<platform>-<architecture>-<toolchain>
where architecture can be
arm
,
x86
，或
x64
. The following is an example of building qtbase for
WinRT
:
> ./configure -xplatform winrt-x64-msvc2013 -release > nmake/jom
WinRT applications must be packaged (including all dependencies) and installed or registered with the application service in order to be launched. The WinRT Runner Tool can be used to launch these applications from the command line.
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
plugins
folder as root. For more information, see
Qt for Windows - 部署
.
As WinRT applications are run in a sandboxed environment, setting the path variable to point to the files required will not work.
The 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 here . The target processor architecture must be specified (as opposed to the default, 'neutral'). As soon as these requirements are met, change into your packaged directory in PowerShell and call:
> Add-AppxPackage -Register AppxManifest.xml
注意： 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' start screen. To remove your application, use Windows' built-in way to uninstall applications (right-click or tap and hold the application and choose
Uninstall
).
注意： The WinRT Runner Tool can perform the same operation with the --remove option.
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.
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.
