  \title Introducing Qt Creator

  Qt Creator provides you with tools to design and develop animated applications for
  mobile devices and to develop complex applications for multiple desktop
  platforms.

  \section1 Developing for Mobile Devices

  \QMLD allows you to easily develop animations by using a declarative programming
  language called QML. You use a visual editor to create widgets and define changes
  in their state. \QMLD generates the necessary code for you.
  You can edit the code in the code editor to add transitions and interaction. You
  can write JavaScript to implement the application logic.

  \section1 Developing for Desktop Platforms

  As an IDE, Qt Creator differs from a text editor in that it knows how to build and run
  applications. It understands the code 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
         that belong to other scopes are not renamed
      \o Show you the locations in code where a function is declared or called
   \endlist

      \section1 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

      You can either create a project from scratch or import an existing
      project. Qt Creator generates all the necessary files, depending on the type of
      project you create. For example, if you choose to create a graphical user
      interface (GUI) application, Qt Creator generates an empty .ui file
      that you can modify with the integrated \QD.

      If you choose to create a QML application, Qt Creator generates a .qml file
      that you can modify with the \QMLD visual editor and the code editor.

    \title Quick Tour

    The figure below shows some of the components of Qt Creator in
    \gui{Edit} mode.

    \image qtcreator-breakdown.png

    \section1 Qt Creator Modes

    The mode selector allows you to quickly switch between tasks such as
    editing project and source files, designing application UIs,
    configuring how projects are built and
    executed, and debugging your applications. To change modes, click the
    icons, or use the \l{keyboard-shortcuts}{corresponding keyboard shortcut}.

    \list
        \o \gui Welcome mode for opening recent sessions and projects.
        \o \gui{\l{Using the Editor}{Edit}} mode for editing project and source files.
        \o \gui{\l{Implementing Application UI}{Design}} mode for designing and developing animated applications for
        mobile devices.
        \o \gui{\l{Debugging}{Debug}} mode for inspecting the state of your program while
           debugging.
        \o \gui{\l{Managing Projects}{Projects}} mode for configuring project building and
           execution.
        \o \gui{\l{Getting Help}{Help}} mode for viewing Qt documentation.
    \endlist

    Certain actions in Qt Creator trigger a mode change. For example,
    \gui {Debug} > \gui {Start Debugging} > \gui {Start Debugging}
    automatically switches to \gui {Debug} mode.


    \section1 Browsing Project Contents

    Use the sidebar to browse files, projects and bookmarks.
    \image qtcreator-sidebar.png

    You can select the content of the sidebar in the sidebar menu:
    \list
        \o \gui Projects shows a list of projects open in the current
           session.
        \o \gui{File System} shows the content of the currently selected
           directory.
        \o \gui Bookmarks shows all bookmarks for the current session.
        \o \gui{Open Documents} shows currently open files.
    \endlist

    You can change the view of the sidebar in the following ways:
    \list
        \o To toggle the sidebar, click \inlineimage qtcreator-togglebutton.png
           or press \key Alt+0 (\key Cmd+0 on Mac OS X).
        \o To split the sidebar, click \inlineimage qtcreator-splitbar.png
           . Select new content to view in the split view.
        \o To close a sidebar view, click
           \inlineimage qtcreator-closesidebar.png
           .
    \endlist


    \section2 Viewing Project Files

    When the sidebar shows projects, they are displayed in a project tree. The
    project tree contains a list of all projects open in the current session.
    The files for each project are grouped according to their file type.

    You can use the project tree in the following ways:
    \list
        \o Double-click a file to open it in an editor.
        \o Right-click an item in the project tree to bring up a
           context menu containing the actions most commonly needed.
           For example, through the menu of the project root directory you can,
           build, re-build, clean and run the project.
        \o To list all files in a project, click
           \inlineimage qtcreator-filter.png
           and select \gui{Simplify Tree}.
        \o During a build, the build system automatically generates source
           files. To hide these files, click \inlineimage qtcreator-filter.png
           and select \gui{Hide Generated Files}.
        \o To toggle the synchronization of your project tree with the file
           opened in the editor, click
           \inlineimage qtcreator-synchronizefocus.png
           .
        \o To see the absolute path of a file, move the mouse pointer over the
           file name.
    \endlist


    \section1 Viewing Output

    The task pane in Qt Creator can display one of the following panes:
    \gui{Build Issues}, \gui{Search Results}, \gui{Application Output}, and
    \gui{Compile Output}. Output panes are available in all
    \l{Qt Creator Modes}{modes}.


    \section2 Build Issues

    The \gui{Build Issues} pane provides a list of errors and warnings
    encoutered during a build. The pane filters out irrelevant output from
    the build tools and presents the issues in an organized way.

    \image qtcreator-build-issues.png


    \section2 Search Results

    The \gui{Search Results} pane displays the results for global searches
    such as searching within a current document, files on disk, or all
    projects. The figure below shows an example output of search result for all
    occurrences of \c textfinder within the \c "/TextFinder" directory.

    \image qtcreator-search-pane.png


    \section2 Application Output

    The \gui{Application Output} pane displays the status of a program when
    it is executed, and the debug output. The figure below shows an example
    output from qDebug().

    \image qtcreator-application-output.png


    \section2 Compile Output

    The \gui{Compile Output} pane provides all output from the compiler. In
    other words, it is a more detailed version of information displayed in the
    \gui{Build Issues} pane.

    \image qtcreator-compile-pane.png


    \section1 Getting Help

    Qt Creator comes fully integrated with Qt documentation and
    examples using the Qt Help plugin. You can get help in the following
    ways:

    \list

    \o To view documentation, switch to \gui Help mode.

    \o To get context sensitive help, move the text cursor to a Qt class or
    function and press \key F1. The documentation is displayed in a pane
    next to the code editor, or, if there is not enough vertical space, in the
    fullscreen \gui Help mode.

    \endlist

    \image qtcreator-context-sensitive-help.png

    To select and configure how the documentation is displayed in the
    \gui Help mode, select \gui Tools > \gui Options > \gui Help.

    \section2 Adding External Documentation

    You can display external documentation in the Qt Creator \gui Help mode.
    To augument or replace the documentation that ships with Qt Creator and Qt:
    \list 1
        \o Create a .qch file from your documentation.

           For information on how to prepare your documentation and create a
           .qch file, see
           \l{http://doc.qt.nokia.com/4.6/qthelp-framework.html}{The Qt Help Framework}.
        \o Add the .qch file to Qt Creator by selecting \gui Tools >
           \gui Options > \gui Help > \gui Documentation > \gui Add.
    \endlist


    \section1 Navigating with Keyboard

    Qt Creator caters not only to developers who are used to using the mouse,
    but also to developers who are more comfortable with the keyboard. A wide
    range of \l{keyboard-shortcuts}{keyboard} and
    \l{Searching With the Locator}{navigation} shortcuts are available to help
    speed up the process of developing your application.

    \section1 Developing Application UI

    To help you design the user interface of your application, two visual
    editors are integrated into Qt Creator:

    \list
    \o \QD
    \o \QMLD
    \endlist

    The integration includes project management and code completion.

    \section1 Using Qt Designer

    Qt Creator automatically opens all .ui files in \QD.

    \image qtcreator-formedit.png

    To change the layout of \QD user interface elements:
    \list 1
        \o Select \gui Tools > \gui{Form Editor} > \gui Views >
           \gui Locked.

           When this option is unchecked, you can change the layout.
        \o Click the header of an element and drag the element to a new
           position.
    \endlist

    To change \QD properties, select \gui Tools > \gui Options >
    \gui Designer.
    \list
        \o Set the class properties and code generation preferences in \gui
           {Class Generation}.
        \o Set an additional folder for saving templates in \gui{Template
           Paths}.
        \o Set the grid settings and preview preferences in \gui Forms. To
           preview your form with skins, enable \gui{Print/Preview
           Configuration} and select your skin. Otherwise default preview
           settings are used.

           To preview the settings, select \gui Tools > \gui{Form Editor} >
           \gui Preview, or press \key Ctrl+Alt+R.
        \o To specify embedded device profiles, such as style, font, and screen
           resolution, select \gui{Embedded Design}.
    \endlist

    For more information on \QD, see
    \l{http://doc.trolltech.com/designer-manual.html}{Qt Designer Manual}.

    \section1 Using QML Designer

    You can edit .qml files in either the visual \QMLD editor or in the
    code editor.

    In \gui Projects, double-click a .gml file to open it in the code
    editor. Then select the \gui {Design} mode to edit the file in the
    visual editor.

    \image qmldesigner-visual-editor.png "Visual editor"

    \title Using the Editor

    Qt Creator's code editor is designed to aid you in creating, editing and
    navigating code. It is fully equipped with syntax checking, code
    completion, context sensitive help and in-line error indicators while you
    are typing.


    \section1 Configuring the Editor

    Qt Creator allows you to configure the text editor to suit your specific
    needs. To configure the editor, select  \gui Tools > \gui Options >
    \gui{Text Editor}:
    \list
        \o Set the font preferences and apply syntax highlighting in
           \gui{Font & Colors}.
        \o Set tabs, indentation and the handling of whitespace in
           \gui Behavior.
        \o Set various display properties, such as
           \l{Highlighting and Folding Blocks}{highlighting and folding blocks},
           text wrapping or \l{Moving to Symbol Definition or Declaration}
           {moving to symbol definition or declaration}
           in \gui Display.
        \o Configure \l{Code Completion}{code completion} in \gui Completion.
    \endlist


    \section1 Using the Editor Toolbar

    The editor toolbar is located at the top of the editor view. It is context
    sensitive and shows items relevant to the file currently open in the
    editor.

    \image qtcreator-editortoolbar-symbols.png

    Use the toolbar to navigate between open files and symbols in use:
    \list
        \o To browse the history of edits for the currently open session, click
           \inlineimage qtcreator-back.png
           and \inlineimage qtcreator-forward.png
           .
        \o To go to any open file, select it from the \gui{Open files}
           drop-down menu.
        \o To jump to any symbol used in the current file, select it from the
           \gui Symbols drop-down menu.
    \endlist

    When you create or edit forms in an .ui file, the toolbar contains
    \QD specific tools.

    If you are using a version control system, the toolbar enables you to
    compare the current file with the version in the repository. For more
    information on using Qt Creator with version control systems, see
    \l{Using Version Control Systems}.


    \section1 Splitting the Editor View

    Split the editor view when you want to work on and view multiple files on
    the same screen.

    \image qtcreator-spliteditorview.png

    You can split the editor view in two ways:
    \list
        \o To split the editor view into a top and bottom view, select
           \gui Window > \gui Split or press \key{Ctrl+E, 2}.

           Split command creates views below the currently active editor view.
        \o To split the editor view into adjacent views, select
           \gui Window > \gui{Split Side by Side} or press
           \key{Ctrl+E, 3}.

           Side by side split command creates views to the right of the
           currently active editor view.
    \endlist

    To move between split views, select \gui Window >
    \gui{Go to Next Split} or press \key{Ctrl+E, 0}.

    To remove a split view, place the cursor within the view you want to
    remove and select \gui Window > \gui{Remove Current Split} or press
    \key{Ctrl+E, 0}. To remove all but the currently selected split view,
    select \gui Window > \gui{Remove All Splits} or press \key{Ctrl+E, 1}.


    \section1 Highlighting and Folding Blocks

    Use block highlighting to visually separate parts of the code that belong
    together. For example, when you place the cursor within the braces,
    the code enclosed in braces is highlighted.

    \image qtcreator-blockhighlighting.png

    To enable block highlighting, select \gui Tools > \gui Options >
    \gui{Text Editor} > \gui Display > \gui{Highlight blocks}.

    Use the folding markers to collapse and expand blocks of code within
    braces. Click the folding marker to collapse or expand a block. In the
    figure above, the folding markers are located between the line number and
    the text pane.

    To show the folding markers, select \gui Tools > \gui Options >
    \gui{Text Editor} > \gui Display > \gui{Display folding markers}.


    \section1 Syntax Checking

    As you write code Qt Creator checks code syntax. When it spots syntax error
    in your code it underlines it and shows error details when you move the
    mouse pointer over the error:
    \list
        \o Syntax errors are underlined in red.

           In the following figure, semicolon is missing at the end of line.

           \image qtcreator-syntaxerror.png
        \o Semantic errors and warnings are underlined in olive.

           In the following figure, the type is unknown.

           \image qtcreator-semanticerror.png
    \endlist


    \section1 Code Completion

    As you write code Qt Creator provides a list of context-sensitive
    suggestions to the statement where your cursor is.

    \image qtcreator-codecompletion.png

    Set code completion preferences in \gui Tools > \gui Options >
    \gui{Text Editor} > \gui Completion.

    When completion is invoked manually, Qt Creator completes the common prefix
    of the list of suggestions. This is especially useful for classes with
    several similarly named members. To disable this functionality, uncheck
    \gui{Autocomplete common prefix} in the code completion preferences.

    The following table lists available types for code completion and icon
    used for each.

    \list 1
        \o On Windows add the editor path to the \bold Path system variable.
           On Linux and Mac OS X add the editor path to the \bold PATH
           environment variable.
        \o In Qt Creator select \gui Tools > \gui Options... >
           \gui Environment > \gui General.
        \o In \gui{External editor} enter the name of the application followed
           by \key Space and \tt{\bold %f}. For example, to open the file in
           Smultron, enter \tt{\bold{smultron %f}}

           To further define how to open the file in the external editor, you
           can use the following variables separated by space:
           \list
            \o Current line number \tt{\bold %l}
            \o Current column number \tt{\bold %c}
            \o Editor's x position on the screen \tt{\bold %x}
            \o Editor's y position on the screen \tt{\bold %y}
            \o Editor's width in pixels \tt{\bold %w}
            \o Editor's height in pixels \tt{\bold %h}
            \o Editor's width in characters \tt{\bold %W}
            \o Editor's height in characters \tt{\bold %H}
            \o To pass % symbol to the editor \tt{\bold %%}
           \endlist

           \note Not all variables work with all editors.

           change and select \gui Tools > \gui C++ >
           \gui{Rename Symbol under Cursor} or press \key Ctrl+Shift+R.

           The \gui{Search Results} pane opens and shows the location and
           number of instances of the symbol in the current project.

           \image qtcreator-refactoring-replace.png
        \o To replace all selected instances, enter the name of the new symbol
           in the \gui{Replace with} text box and click \gui Replace.

           To omit an instance, uncheck the check-box next to the instance.

           \note This action replaces all selected instances of the symbol in
           all files listed in the \gui{Search Results} pane. You cannot
           undo this action.
    \endlist

    \note Renaming local symbols does not open the \gui{Search Results} pane.
    The instances of the symbol are highlighted in code and you can edit the
    symbol. All instances of the local symbol are changed as you type.
