• 使用Row

  Row {        
      anchors.fill: parent
  
      Rectangle {
          id: rect1
          width: parent.width * 0.3
          height: parent.height
          color: "blue"
      }
      Rectangle {
          height: parent.height
          width: parent.width * 0.7
          color: "red"
      }
  }
  

• 使用RowLayout

  RowLayout{
      anchors.fill: parent
      spacing: 0
      Rectangle{
          Layout.fillHeight: true
          Layout.preferredWidth: parent.width * 0.3
          color: "blue"
      }
      Rectangle{
          Layout.fillHeight: true
          Layout.fillWidth: true
          color: "red"
      }
  }
