string QML Value Type

a free form text string. More...

• string is part of Qt for MCUs QML Basic Types.

Detailed Description

The string type refers to a free form text in quotes, for example, "Hello world!".

Example:

Text { text: "Hello world!" }

Strings have a length attribute that holds the number of characters in the string.

The Qt Quick Ultralite string object extends the Javascript String object with the arg() function.

Example:

Text {
    property string message: "There are %1 items"
    property int count: 20

    text: message.arg(count)
}

• Nested arg calls

  Text {
      text: "%1".arg("%1".arg("Hello")) // "Hello"
  }

• Dynamically replacing numbered place marker

  Text {
      text: "%0 %1".arg("%1").arg("Hello") // "Hello Hello"
  }

  Note: You can achieve the above with an alternative qml syntax.

  Example:

  Text {
      property string nested: "%1".arg("Hello")
  
      text: "%1".arg(nested) // "Hello"
  }

  Text {
      property string replaced: "%0 %1".arg("%1")
  
      text: replaced.arg("Hello") // "Hello Hello"
  }

This basic type is provided by the QML language.
