[Laszlo-dev] Help swapping order of subviews

[Henry Minsky]

I am trying to make a horizontal "dock" of icons, where the user can drag
and drop them to re-order them.

I have a view which has a horizontal simplelayout,  and I thought I could
just swap two elements of the subviews
array and call update() on the layout, and they would snap into a new order,
but that doesn't seem to work.

If I swap two views in the subviews array, then rerun the layout's update()
method, the views report properly
changed x coordinates, but they still display at their original locations.
Is there some cache I don't know about
which a view keep for it's children's postitions?

Here's my scrolling view
 <class name="scrollview" defaultplacement="content" clip="true"
focusable="true">
        <attribute name="scrollto" value="0" type="number"/>
        <view x="${-parent.scrollto}" name="content" >
          <simplelayout name="mylayout" axis="x"/>
        </view>
        <scrollbar name="sbx" axis="x" y="120"/>
        <method name="updatelayout">
          this.content.mylayout.update();
        </method>

 </class>
