    Hi,

    What is the best approach to work around the QtQuick1 limitations for this ?

    ListElement: cannot use script for property value
    remainingTimeElementRole: (function () { return (countDownTimerValue / 60 / 10).toFixed(0); }) ();

    I began without a closure, and then I had that idea to try out, but apparently no go.

    Here is the ListModel code:
    javascript Code:
    1. ListModel {
    2. id: remainingTimeModel;
    3. ListElement {
    4. remainingTimeElementRole: (countDownTimerValue / 60 / 10).toFixed(0);
    5. }
    6.  
    7. ListElement {
    8. remainingTimeElementRole: countDownTimerValue / 60 % 10;
    9. }
    10.  
    11. ListElement {
    12. remainingTimeElementRole: ":";
    13. }
    14.  
    15. ListElement {
    16. remainingTimeElementRole: (countDownTimerValue % 60 / 10).toFixed(0);
    17. }
    18.  
    19. ListElement {
    20. remainingTimeElementRole: countTimerDownTimerValue % 60 % 10;
    21. }
    22. }

    Thank you in advance!

    Probably for loop in a Component.onCompleted block inside the ListModel, and call ListModel append() with the appropriate values is the simplest hack around. :/

    Define the function not as a lambda function but as a regular one and call it normally.

    javascript Code:
    1. ListModel {
    2.  
    3. function remainingTime(val) { return (val / 60 / 10).toFixed(0); }
    4.  
    5. ListElement { remainingTimeElementRole: remainingTime(val); }
    6. }

    Your biological and technological distinctiveness will be added to our own. Resistance is futile.
