[Qt-qml] Changing gradient in PropertyChanges

[Rakesh.Mutharaju at tieto.com]

Hi,
         That was really good suggestion from Pertti , hopeful to see that syntax support in future. Thanks Aaron for the hack and for considering.

Please do consider the 'position' changes also.

cheers,
Rakesh

Hi,

Hopefully we'll support the syntax you tried in the future, but for now you've got to do it as a bit of a hack - you have to give the GradientStop's ids and then modify them individually.

For example, this

Rectangle {
     gradient:  Gradient {
        GradientStop { id: stop1; position: 0.0; color: 'blue' }
        GradientStop { id: stop2; position: 1.0; color: 'lightblue' }
    }
}

can then be modified by

    PropertyChanges { target: stop1; color: 'gray' }
    PropertyChanges { target: stop2; color: 'lightgray' }


Cheers,

Aaron

Is it possible to change the gradient of an element in PropertyChanges?
I tried making a fancy button with in QML, but when I try to  change the
gradient I get the error message
"PropertyChanges does not support creating state-specific objects."
Here's the relevant snippet:

     State {
         name: 'pressed'
         PropertyChanges {
             target: self
             gradient:  Gradient {
                 GradientStop { position: 0.0; color: 'gray' }
                 GradientStop { position: 1.0; color: 'lightgray' }
             }
         }
     }
