QtQuick Flickable kinetic movement

Peppy

How to make (using Flickable) kinetic movement of any item on scene? I mean object is able to move (with inertia) although mouse/touch are gone...

andre

Did you try flickDeceleration (property of Flickable)?

Peppy

No, I will look at that...

Hmm... I am thinking wrong (again)... I can't move with rectangle inside flickable element (what am I doing wrong?!)
@

// Nothing really happens
Flickable
{
id: flickable
boundsBehavior: Flickable.DragAndOvershootBounds
flickDeceleration: 0.5
contentHeight: rect.height
contentWidth: rect.width

Rectangle
{
      id: rect

      width: 60
      height: 60

     color: "red"
}

}

Well I think, I am thinking wrong once again ... flickable is just working inside the area of flickable, but not outside??

Hi,

I'm not sure if I understand exactly what you are after, but adding a width and height to the Flickable, e.g.

@width: 400; height: 400@

should make it possible to flick the Rectangle. If you want to flick the Rectangle, and not have it snap back to its original position, you can use a larger contentWidth and contentHeight and play around with the positioning/hierarchy/etc, e.g.

@Flickable
{
id: flickable
width: 400; height: 400
boundsBehavior: Flickable.DragAndOvershootBounds
contentWidth: 740; contentHeight: 740

Rectangle
{
    id: rect

    width: 60
    height: 60
    x: 340; y: 340

    color: "red"
}

}@

The problem is I can't have Flickable through the whole scene because there are also other active objects...hmm... I just want to move that rectangle on scene, but not to affect other objects...

okay that flicking is working, but it means Flickable is just an area, where I can flick?...

Yes, that sounds correct.

You might be able to get something working using the Flickable in a non-traditional manner, for example overlaying the scene with a Flickable with the Flick dynamics you are looking for, and then binding the Rectangle's position based on contextX/contentY (rather than the Rectangle being a child of the Flickable).

I thought, the Flickable is container that allows to move with the object inside over the scene.

Yes, I am looking for kinetic movement with inertia...
