\QDS creates a set of files and folders that you need to create
a UI. The files are listed in the \l{File System} view.
\image loginui1-project-files.png
\list
\li The \e {loginui1.qmlproject} project file defines that all
component, JavaScript, and image files in the project folder belong
to the project. Therefore, you do not need to individually list new
files when you add them to the project.
\li The \e {loginui1.qml} file defines the functionality of
the UI. For the time being, it does not do anything.
\li The \e {Screen01.ui.qml} file is a custom component created by
the wizard template. For more information, see \l {UI files}.
By default, this is the main file in the project, but you can
change that in the .qmlproject file. While the custom component
is a good starting point for new users, you don't have to use it.
Specifically, if you export and import designs using \QB, your main
file is most likely called something else. For more information,
see \l {Exporting from Design Tools}.
\li The \e CMakeLists.txt project configuration file allowing you to
share your project as a fully working C++ application with
developers.
\li The \e {qtquickcontrols2.conf} file specifies the selected
\l {Styling Qt Quick Controls}{UI style} and some style-specific
arguments.
\li The \e imports folder contains \e {Constants.qml} and
\e {DirectoryFontLoader.qml} files that specify a font loader
and a \e qmldir module definition file that declares the Constant
component. For more information, see
\l {Module Definition qmldir Files}. The \e EventListModel.qml and
\e EventListSimulator.qml files are not used in this example, so
you can ignore them for now.
\endlist
\l{UI files} define a hierarchy of components with a highly-readable,
structured layout. Every UI file consists of two parts: an imports section
and a component declaration section. The components and functionality most
common to UIs are provided in the \c QtQuick import. You can view the code
of a \e .ui.qml file in the \l{Code} view.
\section2 Components
\QDS provides preset \l{glossary-component}{components} for creating
UIs, including components for creating and animating visual components,
receiving user input, and creating data models and views.
To be able to use the functionality of preset components, the wizard template
adds the following \e import statements to the UI files (.ui.qml) that it
creates:
\quotefromfile Loginui1/content/Screen01.ui.qml
\skipto import
\printuntil Controls
You can view the import statements in the \uicontrol {Code} view.
The \l Components view lists the components in each module that are
supported by \QDS. You can use the basic components to create your own
components, and they will be listed in \uicontrol {My Components}.
This section is only visible if you have created custom components.
The \l {basic-rectangle}{Rectangle}, \l Text, and \l {Images}{Image}
components used in this tutorial are based on the \l Item component.
It is the base component for all visual elements, with implementation
of basic functions and properties, such as component type, ID, position,
size, and visibility.
For more information, see \l{Use Case - Visual Elements In QML}. For
descriptions of all components, see \l{All QML Types} in the Qt reference
documentation.
\section3 Regtangle properties
The default \l {basic-rectangle}{Rectangle} component is used for drawing
shapes with four sides and four corners. You can fill rectangles either with
a solid fill color or a gradient. You can specify the border color separately.
By setting the value of the radius property, you can create shapes with
rounded corners.
If you want to specify the radius of each corner separately, you can use the
\l{studio-rectangle}{Rectangle} component from the
\uicontrol {Qt Quick Studio Components} module instead of the basic rectangle
component. It is available in \uicontrol Components
> \uicontrol {Qt Quick Studio Components}.
\section3 Text properties
The \l Text component is used for adding static text to the UI, such as
titles and labels. You can select the font to use and specify extensive
properties for each text component, such as size in points or pixels,
weight, style, and spacing.
If you want to create a label with a background, use the \l Label component
from the \uicontrol {Qt Quick Controls} module instead of the text component.
\section3 Image properties
The \l {Images}{Image} component is used for adding images to the UI in several
supported formats, including bitmap formats such as PNG and JPEG and vector
graphics formats such as SVG. To add an image to \uicontrol Assets, select
\imageplus
, and then select the image file.
If you need to display animated images, use the \l {Animated Image}
component, also available in \uicontrol Components >
\uicontrol {Default Components} > \uicontrol Basic.
\section2 UI controls
The \e {Custom Button} wizard template creates a button component
based on the \l {Button} control in the \l {Qt Quick Controls} module. It
is a push-button control that can be pushed or clicked by the user. Buttons
are normally used to perform an action or to answer a question. The
properties and functionality inherited from the Button component enable
you to set text, display an icon, react to mouse clicks, and so on.
To be able to use the functionality of the Button control, the wizard template
adds the following \e import statements to the \e EntryField.ui.qml file:
\quotefromfile Loginui1/content/EntryField.ui.qml
\skipto import
\printuntil Controls
\section2 Component IDs
Each component and each instance of a component has an \e ID that uniquely
identifies it and enables other components' properties to be bound to it.
An ID must be unique, it must begin with a lower-case letter or an
underscore character, and it can contain only letters, numbers, and
underscore characters.
For more information, see \l{The id Attribute}.
