Problem with property bool

Hi
This is my code:

Code:

---

import Qt 4.7
 
Item {
 
    width: 180
    height: 60
    id: root
 
    property bool collapsedButton: true
(...)
    ParallelAnimation {
        running:root.collapsedButton
        NumberAnimation { target: backgroundCallapsed; property: "width"; to: 64 ;}
        NumberAnimation { target: background; property: "opacity"; to: 0 }
        NumberAnimation { target: text; property: "opacity"; to: 0 }
 
    }
(...)

---

Thie code does not work, but when I change "root.collapsedButton" form running to "true" this script work

Define what "does not work" mean. Do you get any errors at the console?

Aniamtion don't run. Console is empty. Variable "collapsedButton" contains value "true", but animation don't start.
I tried this:

Code:

---

import Qt 4.7
 
    Item {
 
    width: 180
    height: 60
    id: root
 
    property bool collapsedButton: true
    (...)
    ParallelAnimation {
    running:{
               if(root.collapsedButton == true){
                     true
                }else{
                     false
}
    NumberAnimation { target: backgroundCallapsed; property: "width"; to: 64 ;}
    NumberAnimation { target: background; property: "opacity"; to: 0 }
    NumberAnimation { target: text; property: "opacity"; to: 0 }
 
    }
    (...)

but aniamtion don't start too.
