Qt is designed for developing applications and user interfaces once and deploying them across several desktop and mobile operating systems.
The easiest way to start application development with Qt is to download and install Qt 5. It contains Qt libraries, examples, documentation, and the necessary development tools, such as the Qt Creator IDE (集成开发环境)。
Qt Creator provides you with tools for accomplishing your tasks throughout the whole application development life-cycle, from creating a project to deploying the application on the target platforms. Qt Creator automates some tasks, such as creating projects, by providing wizards that guide you step-by-step through the project creation process, create the necessary files, and specify settings depending on the choices you make. Also, it speeds up some tasks, such as writing code, by offering semantic highlighting, checking code syntax, code completion, refactoring actions, and other useful features.
