  \title Introducing Qt Creator

  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.
88 89
      \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 for you
      that you can modify with the integrated Qt Designer.

           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
           .

    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 Enable \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
    Qt Designer 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 >
494
    \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

    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.

    Qt Creator can complete common prefixes before showing a list of
    suggestions. This is especially useful for the classes with several
    similarly named members. To use this functionality, in the code
    completion preferences enable \gui{Autocomplete common prefix}.

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

    \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 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.

    Code refactoring is the process of changing the code without modifying the
    existing functionality of your application. By refactoring your code you
    can:
    \list
        \o Improve internal quality of your application
        \o Improve performance and extensibility
        \o Improve code readability and maintainability

    \section1 Selecting the Qt Version

    Qt Creator allows you to have multiple versions of Qt installed on
    your computer and use different versions for your projects.

    If Qt Creator finds \bold qmake in the PATH environment variable, it uses
    that version. This \l{glossary-system-qt}{version of Qt} is referred to as
    \bold{Qt in PATH}. If you intend to use only one version of Qt and it is
    already in the PATH and correctly set up for command line use, you do not
    need to manually configure your Qt version.

    \note By default, Qt Creator compiles projects with the
    \l{glossary-default-qt}{default Qt version}. For information on how to
    override this setting, see \l{Build Settings}.

    \section2 Windows

    To add a Qt version for \bold MinGW:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Click \inlineimage qtcreator-windows-add.png
           and enter the name of the version in \gui{Version Name} field.
        \o Enter the qmake binary path in the \gui{qmake Location}.
        \o Enter the MinGW installation path in the \gui{MinGW Directory}.

           \image qtcreator-qt4-qtversions-win-mingw.png
    \endlist

    To add a Qt version for a \bold{Microsoft Visual C++} compiler:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Qt Creator automatically sets the correct environment variables for
           compilation. Select the internal version number of the installed
           Microsoft Visual C++ tool chains using the \gui MSVC drop-down
           box:
           \list
               \o \bold 7.1 for Visual Studio 2003
               \o \bold 8.0 for Visual Studio 2005
               \o \bold 9.0 for Visual Studio 2008
           \endlist

           \note If you are using the
           \bold{Windows SDK for Windows Server 2008}, Qt Creator identifies
           it as version 9.0.

           \image qtcreator-qt4-qtversions-win-msvc.png
    \endlist

    If you are using \bold{Qt for Symbian} and your S60 SDK is registered
    with devices.exe, Qt Creator automatically detects the Qt version. To add a
    Qt for Symbian version:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Select the \gui{S60 SDK} you want the Qt Creator to use.

           \image qtcreator-qt4-qtversions-win-symbian.png
        \o To build an application for your device using GCCE, enter the path
           to the \bold{CSL ARM Toolchain} directory in
           \gui{CSL\\GCCE Directory}.

           You do not need to specify this path if the compiler is included in
           the PATH environment variable.
        \o To build an application for the emulator (WINSCW toolchain), enter
           the path to your Carbide C++ installation directory in
           \gui{Carbide Directory}.

           You need to have Carbide C++ version 2.0 or later installed.

    Use the \gui Build and \gui Run buttons on *Desktop* to switch between
    the build and run settings for the active project.

    If you have multiple projects open in Qt Creator, use
    \gui{Select a Project} option at the top to navigate between different
    project edits.

    \section1 Build Settings

    Different build configurations allow you to quickly switch between
    different build settings. By default, Qt Creator creates \bold debug
    and \bold release build configurations. Both of these configurations use
    the \l{glossary-default-qt}{default Qt version}.

    \section1 File Encoding

    To define the default file encoding, select the desired encoding in the
    \gui{Editor Settings}. By default, the Qt Creator uses the file encoding
    used by your system.


    \section1 Dependencies

    If you have multiple projects loaded in your session, you can define the
    dependencies between them. This affects the build order of your
    projects.

    \note These dependencies are unrelated to the dependencies inside a qmake
    project.

    To define the dependencies:
    \list 1
        \o Select the project for which you want to configure dependencies.
        \o In the \gui Dependencies section check the checkboxes to select
           other projects as dependencies.
    \endlist


    \section1 Adding External Libraries to a qmake Project

    Through external libraries Qt Creator can support code completion and
    syntax highlighting as if they were part of the current project or the Qt
    library.

    To add an external library:
    \list
        \o Open your project file (.pro) using the \gui Projects pane.
        \o Follow the instructions at \l http://doc.trolltech.com/latest/qmake-project-files.html#declaring-other-libraries
           {Declaring other Libraries}.
    \endlist

    Syntax completion and highlighting work once your project successfully
    builds and links against the external library.

    Once you have installed Qt Creator, it detects automatically if Qt's
    location is in your \c PATH variable. If not, please follow the

    instructions in \l{Selecting the Qt version}.

    We begin with a Qt4 Gui Application project generated by Qt Creator. The

    \l{Creating a project} document describes this process in
1206
    detail. Remember to select QWidget as the Text Finder's base class. If

    your project is not yet loaded, load it by selecting \gui{File} > \gui{Open}.

    \list

    The \c{.h} and \c{.cpp} files come with the necessary boiler plate code.
    The \c{.pro} file is also complete.

    We begin by designing the user interface and then move on to filling
    in the missing code. Finally, we add the find functionality.

    Design the form below with:
    \list
        \o \l{http://doc.trolltech.com/qlabel.html}{QLabel}
        \o \l{http://doc.trolltech.com/qlinedit.html}{QLineEdit} (named lineEdit)
        \o \l{http://doc.trolltech.com/qpushbutton.html}{QPushButton} (named findButton)
        \o \l{http://doc.trolltech.com/qtextedit.html}{QTextEdit} (named textEdit)
    \endlist

    We recommend that you use a \l{http://doc.trolltech.com/qgridlayout.html}{QGridLayout}
    to lay out the label, the line edit and the push button.
    The grid layout and the text edit can then be added to a
    \l{http://doc.trolltech.com/qvboxlayout.html}{QVBoxLayout}.
    If you are new to designing forms with \QD, see the
    \l{http://doc.trolltech.com/designer-manual.html}{Qt Designer Manual}.
