I have following Tumbler defined in main.qml:
Qt Code: 
  1. Tumbler
  2.             {
  3.                 id: ueLoginKeypadTumbler
  4.  
  5.                 Layout.fillWidth: true
  6.                 Layout.fillHeight: false
  7.  
  8.                 height: 100
  9.  
  10.                 antialiasing: true
  11.  
  12.                 TumblerColumn
  13.                 {
  14.                     id: ueNumericTumblerColumnDigit1000
  15.  
  16.                     model: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  17.                 }   // ueNumericTumblerColumnDigit1000
  18.  
  19.                 TumblerColumn
  20.                 {
  21.                     id: ueNumericTumblerColumnDigit100
  22.  
  23.                     model: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  24.                 }   // ueNumericTumblerColumnDigit100
  25.  
  26.                 TumblerColumn
  27.                 {
  28.                     id: ueNumericTumblerColumnDigit10
  29.  
  30.                     model: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  31.                 }   // ueNumericTumblerColumnDigit10
  32.  
  33.                 TumblerColumn
  34.                 {
  35.                     id: ueNumericTumblerColumnDigit1
  36.  
  37.                     model: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  38.                 }   // ueNumericTumblerColumnDigit1
  39.             }   // ueLoginKeypadTumbler

I also have some Button:
Qt Code: 
  1. Button
  2.             {
  3.                 id: ueButtonLogin
  4.  
  5.                 Layout.fillWidth: true
  6.  
  7.                 text: qsTr("Login")
  8.  
  9.                 onClicked:
  10.                 {
  11.                     var uePinCode=ueNumericTumblerColumnDigit1000.model*1000+
  12.                                   ueNumericTumblerColumnDigit100.model*100+
  13.                                   ueNumericTumblerColumnDigit100.model*10+
  14.                                   ueNumericTumblerColumnDigit100.model
  15.                     print(uePinCode)
  16.                 }   // onClicked - gather Tumbler value
  17.             }   // ueButtonLogin
To copy to clipboard, switch view to plain text mode 
How do I get value of Tumbler in Button's onClicked:?
Sincerely,
Marko
