  \title Introducing Qt Creator

Leena Miettinen's avatar

    Qt Creator is an integrated development environment (IDE) that provides you with
Leena Miettinen's avatar
Leena Miettinen committed
171
172
173
174
175
    tools to design and develop applications with the Qt application framework. Qt is designed for
    developing applications and user interfaces once and deploying them across several
    desktop and mobile operating systems. Qt Creator provides you with tools for
    accomplishing your tasks throughout the whole application development life-cycle,
    from creating a project to deploying the application on the target platforms.

182

184
    One of the major advantages of Qt Creator is that it allows a team of developers
    to share a project across different development platforms with a common tool
    for development and debugging.

    The recommended way to build a project is to use a version control system.
    Store and edit only project source files and the .pro and .pri files (for qmake)
    or CMakeLists.txt and *.cmake files (for CMake). Do not store
    files generated by the build system or Qt Creator, such as makefiles,
    .pro.user, and object files. Other approaches are possible,
    but we recommend that you do not use network resources, for example.

    Qt Creator allows you to specify separate build settings
    for each development platform. By default, \l{glossary-shadow-build}{shadow builds} are used to
    keep the build specific files separate from the source.

    You can create separate versions of project files to keep platform-dependent
    code separate. You can use qmake
    \l{http://qt.nokia.com/doc/4.7/qmake-tutorial.html#adding-platform-specific-source-files}{scopes}
    to select the file to process depending on which platform qmake is run on.

    Items such as open files, breakpoints, and watchers are stored in

    sessions. They are not considered to be part of the
    information shared across platforms.

    \section1 Creating Projects

    But why do you need projects? To be able to build and run applications,
    Qt Creator needs the same information as a compiler would need. This information
    is specified in the project build and run settings.

    Creating a project allows you to:

        \list

            \o Group files together

            \o Add custom build steps

            \o Include forms and resource files

            \o Specify settings for running applications

        \endlist

    Setting up a new project in Qt Creator is aided by a wizard that guides
    you step-by-step through the project creation process. In the first step, you
Leena Miettinen's avatar
Leena Miettinen committed
227
228
    select the type of the project from the categories: Qt Quick project, Qt widget
    project, or other project. Next, you select a location for the project and

232

234
235
236
237
238
239
    specify settings for it.

    \image qtcreator-new-qt-quick-project-wizard.png

    When you have completed the steps, Qt Creator automatically generates the
    project with required headers, source files, user interface descriptions
    and project files, as defined by the wizard.
    For example, if you choose to create a Qt Quick application, Qt Creator
    generates a QML file that you can modify with the integrated \QMLD.

    \section2 Adding Libraries
240
241
242
243
244
245

    In addition to Qt libraries, you can link your application to other
    libraries, such as system libraries or your own libraries. Further, your
    own libraries might link to other libraries. To be able to compile your
    project, you must add the libraries to your project. This also enables
    code completion and syntax highlighting for the libraries.
Leena Miettinen's avatar
Leena Miettinen committed
246
    The procedure of adding a library to a project depends on the build
247
248
    system that you use.

    \section2 Version Control Systems

    Qt Creator uses the version control system's command line clients to access
    your repositories. The following version control systems are supported:

    The functions available to you in Qt Creator depend on the version control
    system. Basic functions are available for all the supported systems. They include
    comparing files with the latest versions stored in the repository and displaying the
    differences, viewing versioning history and change details, annotating files,
    and committing and reverting changes.

    Large high-resolution screens, touch input, and significant graphics power
    are becoming common in portable consumer devices, such as mobile
    phones, media players, set-top boxes, and netbooks. To fully benefit from
    these features and to create intuitive, modern-looking, fluid user interfaces,
    you can use \l {http://doc.qt.nokia.com/4.7/qtquick.html}{Qt Quick}.

    Qt Quick consists of a rich set of user interface elements, a declarative
    language for describing user interfaces, and a language runtime. A
    collection of C++ APIs is used to integrate these high level features with
    classic Qt applications.
292

Leena Miettinen's avatar

    You can edit QML code in the code editor or in the integrated \QMLD.
    The integration includes project management and code completion.

    If you need a traditional user interface that is clearly structured and
    enforces a platform look and feel, you can use the integrated \QD. You can
    compose and customize your widgets or dialogs and test them using different
    styles and resolutions.

    As an IDE, Qt Creator differs from a text editor in that it knows how to build and run
    applications. It understands the C++ and QML languages as code, not just as plain text. This allows
    it to:

    \list

        \o Enable you to write well formatted code

        \o Anticipate what you are going to write and complete the code

        \o Display inline error and warning messages

        \o Enable you to semantically navigate to classes, functions, and symbols

        \o Provide you with context-sensitive help on classes, functions, and symbols

        \o Rename symbols in an intelligent way, so that other symbols with the same name
320
         that belong to other scopes are not renamed
Leena Miettinen's avatar

322
        \o Show you the locations in code where a function is declared or called

    QML declarative programming language.

331
    QML is an extension to JavaScript, that provides a mechanism to declaratively build
    an object tree of QML elements. QML improves the integration between JavaScript and
    Qt's existing QObject based type system, adds support for automatic property bindings
    and provides network transparency at the language level.

    Qt Creator is integrated with cross-platform systems for build automation:
    qmake and CMake. In addition, you can import generic projects that do not use qmake
    or CMake, and specify that Qt Creator ignores your build system.

    Qt Creator provides support for building and running Qt applications for
    desktop environment (Windows, Linux, and Mac OS) and mobile devices (Symbian and Maemo).
    Build settings allow you to quickly switch between build targets.

    When you install the \QSDK, the build and run settings for the Maemo and Symbian
    targets are set up automatically. However, you need to install and configure some
    additional software on the devices to be able to connect to them from the
    development PC.

    If you install Qt Creator as part of \QSDK, the GNU Symbolic Debugger
    is installed automatically and you should be ready to start debugging after
    you create a new project. However, you can change the setup to use debugging
    tools for Windows, for example.
    You can connect mobile devices to your development PC and debug processes
    running on the devices.

    Simulator and Maemo Emulator, but you also need to test the applications
    on real devices.

    You can use the Qt Creator \gui Debug mode to inspect the state of your
    application while debugging. You can interact with the debugger in several
    ways, including the following:

    \list
        \o Go through a program line-by-line or instruction-by-instruction.
        \o Interrupt running programs.
        \o Set breakpoints.
        \o Examine the contents of the call stack.
        \o Examine and modify registers and memory contents of
           the debugged program.
        \o Examine and modify registers and memory contents of
           local and global variables.
        \o Examine the list of loaded shared libraries.
        \o Create snapshots of the current state of the debugged program
           and re-examine them later.
    \endlist

    Qt Creator displays the raw information provided by the native debuggers
    in a clear and concise manner with the goal to simplify the debugging process
    as much as possible without losing the power of the native debuggers.

    In addition to the generic IDE functionality provided by stack view, views for
    locals and watchers, registers, and so on, Qt Creator includes
    features to make debugging Qt-based applications easy. The debugger
    plugin understands the internal layout of several Qt classes, for
    example, QString, the Qt containers, and most importantly QObject
    (and classes derived from it), as well as most containers of the C++
    Standard Library and some gcc and Symbian extensions. This
    deeper understanding is used to present objects of such classes in
    a useful way.

    You can use the Qt Creator \gui Debug mode to inspect the state of
    the application while debugging JavaScript functions. You can set breakpoints,
    view call stack trace, and examine locals and watchers.

    When the application is interrupted by a breakpoint, you can use the \gui {QML
    Script Console} to execute JavaScript expressions in the current context. You can
    type JavaScript expressions and use them to get information about the state of the
    application, such as property values.

    If you change property values or add properties in the code editor, the
    changes are updated in the running application when they are saved.

    \section3 QML Observer

    While the application is running, you can use the \gui {QML Observer} view to
    explore the object structure, debug animations, and inspect colors. When debugging
    complex applications, you can use the observe mode to jump to the position in code
    where an element is defined.

    \section2 Qt Simulator

    You can use the Qt Simulator to test Qt applications that are intended
    for mobile devices in an environment similar to that of the device. You
    can change the information that the device has about its configuration
    and environment.

    The Qt Simulator is installed as part of the \QSDK. After it is
    installed, you can select it as a build target in Qt Creator.

    \section2 Maemo Emulator

443
    The Maemo 5 emulator emulates the Nokia N900 device environment. You can test
Leena Miettinen's avatar
Leena Miettinen committed
444
    applications in conditions practically identical to running the application
445
    on a Nokia N900 device with the software update release 1.3 (V20.2010.36-2).
Leena Miettinen's avatar

    However, it is faster to test on a real device connected to the development
    PC.

    The Maemo Emulator is installed as part of the \QSDK. After it is
450
    installed, you can start it from Qt Creator.

    \section1 Deploying

    Qt Creator deploy configurations handle the packaging of the application as an
    executable and copying it to a location developers want to run the executable at.
    The files can be copied to a location in the file system of the development PC
    or to a mobile device.

    Qt Creator allows you to create installation packages for Symbian and Maemo
    devices that are suitable for publishing on Ovi Store and other channels.

    You can filter the documents displayed in the \gui Help mode to find
    relevant information faster. Select from a list of filters in the
    \gui {Filtered by} field. The contents of the \gui Index and \gui Contents
    pane in the sidebar change accordingly.

    \image qtcreator-help-filters.png "Help filters"

    You can modify the filters to include external documentation, for example,
    or you can define your own filters. To construct filters, you can use the
    filter attributes that are specified in the documentation. Each document
    contains at least one filter attribute. If several documents contain the
    same filter attribute, such as \c tools, you can use that attribute to
    include all those documents.

    To add filters:

    \list 1

        \o Select \gui {Tools > Options... > Help > Filters > Add}.

        \o Enter a name for the filter and press \gui {OK}.

        \o In \gui Attributes, select the documents that you want to include
        in the filter.

        \image qtcreator-help-filter-attributes.png "Help filter attributes"

        \o Click \gui OK.

        \o In the \gui Help mode, select the filter in the \gui {Filtered by}
        field to see the filtered documentation in the sidebar.

    \endlist

    To modify filters, select a filter in \gui Filters, select the attributes,
    and then click \gui Apply.

    To remove filters, select them in \gui Filters, and click \gui Remove.

    Large high-resolution screens, touch input, and significant graphics power
    are becoming common in portable consumer devices, such as mobile
    phones, media players, set-top boxes, and netbooks. To fully benefit from
    these features and to create intuitive, modern-looking, fluid user interfaces,
    you can use \l {http://doc.qt.nokia.com/4.7/qtquick.html}{Qt Quick}.
981

982
983
984
985
    Qt Quick consists of a rich set of user interface elements, a declarative
    language for describing user interfaces, and a language runtime. A
    collection of C++ APIs is used to integrate these high level features with
    classic Qt applications.
986

987
    You can edit QML code in the code editor or in the integrated \QMLD.
