  \title Introducing Qt Creator

92 93
  Qt Creator provides you with tools to design and develop user interfaces and
  complex applications for multiple desktop and mobile
94 95
  platforms.

96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114
  \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.
115 116

  \QMLD allows you to easily develop animations by using a declarative programming
117 118 119 120
  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
121
  in their state. \QMLD generates the necessary code for you.
122 123 124
  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 to implement the application logic.
125

  \section1 Coding Applications
127

Leena Miettinen's avatar

128 129 130 131
  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
132 133 134 135 136
      \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
137
      \o Rename symbols in an intelligent way, so that other symbols with the same name
138 139
         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
150 151 152 153
      \o Group files together
      \o Add custom build steps
      \o Include forms and resource files
      \o Specify settings for running applications
Leena Miettinen's avatar
Leena Miettinen committed
154 155 156 157 158
      \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
159 160 161 162 163
      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.

    You can split the editor view in the following ways:

        \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 >
615
    \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

645 646 647
    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.

    \section1 Code Completion

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

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

672 673 674 675
    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.

    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

    To find the use of a specific symbol in your project:
    \list 1
        \o In the editor place the cursor on the symbol and select \gui Tools
           > \gui C++ > \gui{Rename Symbol under Cursor} or press
           \key Ctrl+Shift+U.

           Qt Creator looks for the symbol in the following locations:
           \list
            \o Files listed as a part of the project
            \o Files directly used by the project files (for example, generated

            \o Header files of used frameworks and libraries
           \endlist
        \o The \gui{Search Results} pane opens and shows the location and
           number of instances of the symbol in the current project.

        \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
