## Detailed Description

The Universal style is a device-agnostic style based on the Microsoft Universal Design Guidelines. The Universal style has been designed to look good on all devices, from phones and tablets to PCs.

The Universal style in light and dark themes

Note: The Universal style is not a native Windows 10 style. The Universal style is a 100% cross-platform Qt Labs Controls style implementation that follows the Microsoft Universal Design Guidelines. The style runs on any platform, and looks more or less identical everywhere. Minor differences may occur due to differences in available system fonts and font rendering engines.

### Customization

The Universal style allows customizing two attributes, theme and accent. The following example illustrates how to create a red stop button with light text:

      import QtQuick 2.0
      import Qt.labs.controls 1.0
      import Qt.labs.controls.universal 1.0

      Button {
          text: "Stop"
          highlighted: true

          Universal.accent: Universal.Red
          Universal.theme: Universal.Dark
      }

Both attributes can be specified for any window or item, and they automatically propagate to children in the same manner as fonts. In the following example, the window and all three radio buttons appear in the dark theme using a violet accent color:

      import QtQuick 2.0
      import Qt.labs.controls 1.0
      import Qt.labs.controls.universal 1.0

      ApplicationWindow {
          visible: true

          Universal.theme: Universal.Dark
          Universal.accent: Universal.Violet

          Column {
              anchors.centerIn: parent

              RadioButton { text: qsTr("Small") }
              RadioButton { text: qsTr("Medium");  checked: true }
              RadioButton { text: qsTr("Large") }
          }
      }

Note: The Universal style must be separately imported to gain access to these style-specific attributes. It should be noted that regardless of the references to the Universal style, the same application code runs with any other style. The Universal style-specific attributes only have an effect when the application is run with the Universal style. Furthermore, in case of explicit Universal style-specific references, the Universal style must be deployed with the application.

Note: Types in the Qt.labs module are not guaranteed to remain compatible in future versions.
