  \title Introducing Qt Creator

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

  \section1 Designing User Interfaces

  Qt Creator provides two integrated visual editors, \QD and \QMLD.

  \QD is a tool for designing and building graphical user interfaces (GUIs) from
  Qt widgets. You can compose and customize your widgets or dialogs and test
  them using different styles and resolutions.

  Widgets and forms created with \QD are integrated seamlessly with programmed code,
  using the Qt signals and slots mechanism, that lets you easily assign behavior to
  graphical elements. All properties set in \QD can be changed dynamically within the code.
  Furthermore, features like widget promotion and custom plugins allow you to use your
  own widgets with \QD.

  UIs that use widgets are clearly structured and enforce a platform look and feel,
  which makes them useful for traditional applications. However, they are static, and
  do not fully make use of the large high-resolution screens, touch input, and significant
  graphics power that are becoming common in portable consumer devices, such as mobile
  phones, media players, set-top boxes, and netbooks.

  \QMLD allows you to easily develop animations by using a declarative programming
  language called \l {http://qt.nokia.com/doc/4.7-snapshot/declarativeui.html}{QML}.
  In QML, a user interface is specified as a tree of objects with properties.

  You use a visual editor to create items, screens, and applications, as well as define changes
  in their state. \QMLD generates the necessary code for you.

  \note The visual \QMLD editor is provided as an experimental plugin that you must
  enable to be able to edit QML files in the \gui Design mode. Enabling the
  visual editor can negatively affect the overall stability of Qt Creator.

  You can edit the code in the code editor to add transitions from one state to another,
  and interaction to specify user actions that change the states. You
  can use Qt or JavaScript to implement the application logic.

  \section1 Coding Applications

  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 Qt Quick 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

    Qt Creator has been localized into several languages. If the system language
    is one of the supported languages, it is automatically selected. To change
    the language, select \gui {Tools > Options > Environment} and select a language
    in the \gui Language field. The change takes effect after you restart Qt Creator.

    \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{Developing Application UI}{Design}} mode for designing and developing
           application user interfaces.
        \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. Clicking on
    \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

           .
    \endlist


    \section2 Viewing Project Files

    The sidebar displays projects 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 To bring up a context menu containing the actions most commonly
           needed right-click an item in the project tree.
           For example, through the menu of the project root directory you can,
           among other actions, 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 To hide source files which are automatically generated by the build
           system, during a build, 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:
    \list
       \o  \gui{Build Issues}
       \o  \gui{Search Results}
       \o  \gui{Application Output}
       \o  \gui{Compile Output}
    \endlist

    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
    encountered during a build. The pane filters out irrelevant output from
    the build tools and presents the issues in an organized way.

    Right-clicking on a line brings up a context menu with options to copy
    the contents and to show a version control annotation view of the
    line that causes the error message.

    \image qtcreator-build-issues.png


    \section2 Search Results

    The \gui{Search Results} pane displays the results for global searches,
    for example, searching within a current document, files on disk, or all
    projects.

    The figure below shows an example 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.
    The \gui{Compile Output} 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.
    \list
        \o To view documentation, switch to \gui Help mode.
        \o To obtain 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.

           \image qtcreator-context-sensitive-help.png

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

    \section2 Adding External Documentation

    You can display external documentation in the \gui Help mode.
    To augment 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 To add the .qch file to Qt Creator, select \gui Tools >
           \gui Options... > \gui Help > \gui Documentation > \gui Add.
    \endlist

    \section2 Using Documentation Filters

    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.

    \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 Qt Quick Designer

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

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

    \note The visual \QMLD editor is provided as an experimental plugin that you must
    enable to be able to edit QML files in the \gui Design mode. Enabling the
    visual editor can negatively affect the overall stability of Qt Creator.

    To enable or disable the \QMLD visual editor, select
    \gui {Help > About Plugins... > Qt Quick > QmlDesigner}. You must restart Qt Creator
    to enable or disable the visual editor.

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

    Use the visual editor panes to manage your project:

    \list

    \o \gui {Navigator} pane displays the items in the scene. You can
    show and hide items to focus on specific parts of the application.

    \o \gui {Library} pane displays lists of predefined \gui {Items} and
    imported \gui {Resources} that you can use to design applications. The
    images and other files that you copy to the project folder appear in the
    \gui {Resources} pane.

    \o \gui {Properties} pane displays the properties of the selected component.
     You can also change the properties in the code editor.

    \o \gui {State} pane displays the different states of the component. To add
    states, click the empty slot. Then modify the new state in the editor.
    In the code editor, you can see the changes recorded as changes to
    the base state.

    \endlist

    \title Using the Editor

    Qt Creator's code editor is designed to aid you in creating, editing and
    navigating code.  Qt Creator's code editor 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}

    You can perform the following configuration actions:
    \list
        \o Set the font preferences and apply syntax highlighting in
           \gui{Font & Colors}.
        \o Set tabs, indentation, the handling of whitespace, and mouse operations in
           \gui Behavior.
        \o Set various display properties, for example,
           \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{Completing Code}{code completion} in \gui Completion.
    \endlist


    \section1 Using the Editor Toolbar

    The editor toolbar is located at the top of the editor view. The editor
    toolbar 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 forward or backward through your location history, 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 a \c{.ui} file, the toolbar contains
    Qt Designer specific tools.


    \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 the following 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, O}.

    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}. This
    option is enabled by default.


    \section1 Checking Code Syntax

    As you write code Qt Creator checks code syntax. When Qt Creator spots a
    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, a semicolon is missing at the end of the
           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 Completing Code

    Qt Creator understands the code as code, not just as plain text. This
    allows it to help you to write well formatted code and to anticipate
    what you are going to write and complete the code. The code completion
    differs somewhat depending on whether you write Qt code or QML code.

    \section2 Completing Qt Code

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

    \image qtcreator-codecompletion.png

    To open the list of suggestions at any time, press \key{Ctrl+Space}.
    If only one option is available, Qt Creator inserts it automatically.

    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.
    Select \gui Tools > \gui{Options...} > \gui{Text Editor} > \gui Completion.

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

    \table
        \header
            \o Icon
            \o Description
        \row
            \i  \inlineimage completion/class.png
            \i  A class

            \i  \inlineimage completion/slot_priv.png
            \i  A private slot
        \row
            \i  \inlineimage completion/slot_prot.png
            \i  A protected slot
        \row
            \i  \inlineimage completion/keyword.png
            \i  A keyword
        \row
            \i  \inlineimage completion/macro.png
            \i  A macro
        \row
            \i  \inlineimage completion/namespace.png
            \i  A namespace
    \endtable

    \section2 Completing QML Code

    As you write QML code, Qt Creator suggests properties, IDs, and code
    snippets to complete the code. The snippets can consist of multiple
    fields that you specify values for. Select an item in the list and press
    \key Tab or \key Enter to complete the code. Press \key Tab to
    move between the fields and specify values for them.

    \image qmldesigner-code-completion.png "Completing QML code"

    \section1 Using Bookmarks

    To insert or delete a bookmark right-click the line number and select
    \gui{Toggle Bookmark} or press \key{Ctrl+M}.

    \image qtcreator-togglebookmark.png

    To go to previous bookmark in the current session, press \key{Ctrl+,}.

    To go to next bookmark in the current session, press \key{Ctrl+.}.


    \section1 Moving to Symbol Definition or Declaration

    In Qt Creator you can move directly to the definition or the declaration of
    a symbol by holding the \key Ctrl and clicking the symbol.

    To enable this moving function, in \gui Tools > \gui{Options...} >
    \gui{Text Editor} > \gui Behavior select \gui{Enable mouse navigation}.


    \section1 Using Update Code Model

    To refresh the internal information in Qt Creator pertaining to your code,
    select \gui{Tools} > \gui{C++} > \gui{Update Code Model}.

    \note In Qt Creator indexing updates the code automatically. Use
    \gui{Update Code Model} only as an emergency command.


    \section1 Pasting and Fetching Code Snippets

    In Qt Creator, you can paste snippets of code to a server or fetch
    snippets of code from the server. To paste and fetch snippets of code,
    Qt Creator uses the following:
    \list
        \o \gui{CodePaster}
        \o \gui{Pastebin.Com}
        \o \gui{Pastebin.Ca}
    \endlist

    To configure the server, select \gui{Tools} > \gui{Options...} >
    \gui{Code Pasting}.

    To paste a snippet of code onto the server, select \gui{Tools} >
    \gui{Code Pasting} > \gui{Paste Snippet...} or press \key{Alt+C,Alt+P}.

    To fetch a snippet of code from the server, select \gui{Tools} >
    \gui{Code Pasting} > \gui{Fetch Snippet...} or press \key{Alt+C,Alt+F}.

    \note To use \gui{Pastebin.Com}, configure the domain
    prefix in \gui{Tools} > \gui{Options...} > \gui{Code Pasting} >
    \gui{Pastebin.com}.

    For example, you might ask colleagues to review a change that you plan to
    submit to a version control system. If you use the git version control system,
    you can create a \e{diff} view by selecting \gui{Tools} > \gui{Git} >
    \gui{Diff Repository}. You can then upload its contents to the server by choosing
    \gui{Tools} > \gui{Code Pasting} > \gui{Paste Snippet...}. The reviewers can retrieve
    the code snippet by selecting \gui{Tools} > \gui{Code Pasting} > \gui{Fetch Snippet...}.
    If they have the project currently opened in Qt Creator, they can apply and test
    the change by choosing \gui{Tools} > \gui{Git} > \gui{Apply Patch}.

    \section1 Using FakeVim Mode

    In the \gui{FakeVim} mode, you can run the main editor in a manner similar
    to the Vim editor. To run the editor in the \gui{FakeVim} mode, select
    \gui{Edit} > \gui{Advanced} > \gui{Use Vim-style Editing} or press
    \key{Alt+V,Alt+V}.

    In the \gui{FakeVim} mode, most keystrokes in the main editor will be
    intercepted and interpreted in a way that resembles Vim. Documentation for
    Vim is not included in Qt Creator. For more information on using Vim,
    see \l{http://www.vim.org/docs.php}{Documentation} on the Vim web site.

    To map commands entered on the \gui{FakeVim} command line to actions of the
    Qt Creator core, select \gui{Tools} > \gui{Options...} > \gui{FakeVim} >
    \gui{Ex Command Mapping}.

    To make changes to the Vim style settings, select \gui{Tools} >
    \gui{Options...} > \gui{General}.

    To quit the FakeVim mode, click \gui {Quit FakeVim} or press
    \key{Alt+V,Alt+V}.


    \section1 Using an External Editor

    To open the file you are currently viewing in an external editor, select
    \gui Edit > \gui Advanced > \gui{Open in External Editor}.

    To use the external editor of your choice:
    \list 1
        \o Add the editor path to the \c{PATH} environment variable of your
           operating system.
        \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 a 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.
    \endlist

           \inlineimage qtcreator-editor-regularexpressions.png
           .
           Regular expressions used in Qt Creator are modeled on Perl regular
           expressions. For more information on using regular expressions, see
           \l {http://doc.qt.nokia.com/4.6/qregexp.html#details}
           {Detailed Description} in the QRegExp Class Reference.
    \endlist

    \note If you have selected text before selecting \gui Find/Replace, the
    search is conducted within the selection.

    To replace occurrences of the existing text, enter the new text in the
    \gui{Replace with} field.
    \list
        \o To replace the selected occurrence and move to the next one,
           click \inlineimage qtcreator-next.png
           or press \key Ctrl+=.
