You can use wizards to create Qt Quick projects.

Some of the wizards create Qt Quick projects that contain UI forms (.ui.qml files). The forms use a purely declarative subset of the QML language and you can edit them in the Design mode.

You can use the code editor (Edit mode) or the visual editor (Design mode) to develop Qt Quick applications.

You can use basic QML types to create your own components that you can combine with ready-made Qt Quick Controls and Layouts (available since Qt 5.1).

You can combine basic QML types with ready-made Qt Quick Controls, Dialogs, and Layouts (available since Qt 5.1) to create screens. You can use states and transitions to navigate between screens.

Qt Quick Designer contains commercial features that make developing Qt Quick applications faster and easier.

You can export designs from graphics software, such as Adobe Photoshop and GIMP, to QML files. You can then edit QML files in Qt Creator.

QML modules may use plugins to expose components defined in C++ to QML applications. Qt Creator cannot load the plugins to determine the details of the contained components, and therefore, the modules must provide extra type information for code completion and the semantic checks to work correctly.
