Editing QML Files in Design Mode ◦ Creating Components

# Creating UIs

Qt Quick enables you to build UIs around the behavior of components and how they connect with one another. You create components using Qt Quick and QML types that are available in the Design mode. You can specify values for the properties of a component to change its appearance and behavior. All QML types have a set of predefined properties, some of which control things that are visible to users, while others are used behind the scene.

While it is useful to learn the basics of Qt Quick, you can also rely on Qt Quick Designer to write the code for you when you drag-and-drop the ready-made components to the Form Editor view and change them to your liking by modifying their properties in the Properties view in the Design mode. You can always check up details in the extensive Qt Quick documentation by pressing F1.

- Creating Components

  In addition to your imported artwork, you can use the Design mode to customize ready-made components or design any custom form and shape directly as QML types. You can import visual assets in various formats, such as PNG, JPG, and SVG for use in the components.

- Managing Item Hierarchy

  You can manage the items in the current QML file and their relationships in the Navigator.

- Specifying Item Properties

  You can specify values for the properties of a component to change its appearance and behavior. All QML types have a set of predefined properties. Some properties, such as position, size, and visibility, are common to all QML types, whereas others are specific to the QML type. You can specify properties for your components in the Properties view.

- Using Custom Fonts

  You can load custom fonts to Qt Quick Designer and use them in your designs.

- Annotating Designs

  You can annotate your designs to provide reviewers or developers with additional information about them.

- Qt Quick UI Forms

  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.
