slider control

[wysota]

It means nothing as the expression is likely invalid. If it works, then it will once resize the current item to the other item at the moment when the expression is evaluated (provided that no contradictory anchors are defined for the item) which is probably not what you want.

I would like to point out we still don't know what you are trying to do so it is quite demanding to suggest a solution to an unknown problem.

Consider the fact the we have already defined the layout.

The fact that the rectangle has a sibling item?

Does the above statement mean any of the following:

1. The grid layout is stick to the rectangle or the other way around.

"fill" is basically a shortcut for

anchors {
    left: other.left
    right: other.right
    top: other.top
    bottom: other.bottom
}

anchors {
    left: other.left
    right: other.right
    top: other.top
    bottom: other.bottom
}

To copy to clipboard, switch view to plain text mode 

If the grid layout is stick to the rectangle , should it be problem to move it ?

Try that with real world objects:
- take a piece of paper
- glue it onto another piece of paper
- now try to move one while not moving the other.

If not, then , how would you suggest to get it fixed ?

Since they are independent, position them independently.

Please Check the following screen-shot:

Do you see the UI(slider and text arranged in the grid layout) at the top left corner of the window ?


What i want to get is:

1. The UI will slide inside/outside of the window using the spring animation with the key press event (F1).

So the rectangle and the grid are not independent?

Then your answer is in comment #6

P.S.: and in general it would be really helpful if you actually read what people are writing, i.e. answering question instead of ignoring everything and writing vague randomness

So what exactly is the problem and how is it related to anything written so far in this thread? Either use a Behavior or states with a transition.
