The main goal for Qt Creator is meeting the development needs of Qt developers who are looking for simplicity, usability, productivity, extendibility and openness, while aiming to lower the barrier of entry for newers to Qt. The key features of Qt Creator allow the developers to acplish the following tasks: ? Get started with Qt application development quickly and easily with project wizards, and quickly access recent projects and sessions. ? Design Qt widgetbased application user interface with the integrated editor, Qt Designer. ? Develop applications with the advanced C++ code editor that provides new powerful features for pleting code snippets, refactoring code, and viewing the outline of files (that is, the symbol hierarchy of a file). ? Build, run, and deploy Qt projects that target multiple desktop and mobile platforms, such as Microsoft Windows, Mac OS X, Linux, Symbian, MeeGo, and Maemo. ? Debug with the GNU and CDB debuggers using a graphical user interface with increased awareness of Qt class structures. ? Use code analysis tools to check for memory management issues in your applications. ? Deploy applications to mobile devices and create application installation packages for Symbian, MeeGo, and Maemo devices that can be published in the Ovi Store and other channels. ? Easily access information with the integrated contextsensitive Qt Help system. Qt Creator is part of Qt Quick, which allows designers and developers to create the kind of intuitive, modernlooking, fluid user interfaces that are increasingly used on mobile phones, media players, settop boxes and other portable devices. Qt Creator enables collaboration between designers and developers. Supported Operating Systems Qt Creator installation packages are available for Microsoft Windows, Mac OS X, and Linux. Qt Creator can be run on other platforms, but that requires the pilation of the publicly available source code. Building and running Qt Creator from source code may require a separate installation of Qt on your puter. Working with Qt Creator When you start Qt Creator, it opens to the Wele mode, where you can open tutorials and example projects or start the project wizard to create your own projects. Qt Creator meets its design goals of simplicity, easeofuse, and productivity by relying on the concept of modes. These adapt the user interface to the different application development tasks at hand. Developers can use 5 the mode selector or keyboard shortcuts to switch to a Qt Creator mode. Each mode has its own view that shows only the information required for performing a given task and provides only the most relevant features and functions related to it. As a result, the majority of the Qt Creator window area is always dedicated to actual application development tasks. Creating Projects To be able to build and run applications, Qt Creator needs the same information as a piler would need. This information is specified in the project build and run settings. When the steps have been pleted, Qt Creator automatically generates the project with required headers, source files, user interface descriptions and project files, as defined by the wizard. Not only does the wizard help new users get up and running quickly, it also enables more experienced users to streamline their workflow for the creation of new projects. The convenient user interface makes it easier to ensure that a project begins with the correct configuration and dependencies. Designing User Interface Qt Creator provides a fully integrated visual editor, Qt Designer. Qt Designer is a tool for designing and
