Hi,
Perhaps someone has tried to do this and has figured it out.
Me...no. The objective is to take image snapshots from the display
objects on individual tabs (children) of the tab navigator and use
them for a tile list in another container...preferrably on another
tab of the TabNavigator.
The problem seems to be that only the visible tab can be snapped.
Taking snapshots of the other non selected children produces what
appears to be a very narrow slice of display...
Stepping through the children, selectedIndex = i, setting that child
to be visible, taking a snapshot, all programmatically without user
interaction does not work. Again, one valid snapshot, and the rest
are some machination of some image with positive size, but only a
slice. I've done quite a bit with snapshots before so I'm confident
in that part of the code (getting the snapshot of bitmapData, using
it to form a Bitmap Object, wrapping in UIComponent, adding as child
to container), and I'm picking up one successfully but no luck on
picking them all up. I set breakpoints at the first point of the
snapshot and the size tells me its not the full display object. I'm
sticking the snapshots in a model and using to source the list. The
copy in the model has only the single full image.
I've even tried making a copy of the display objects themselves and
presenting them in the tile list but for whatever reason, the instant
I add the child to the tilelist container, it is no longer visible in
the original tab.
Its a barchart image I'm trying to capture so I try
var cloneBarChart:BarChart = new BarChart();
cloneBarChart = this.barChartDisplay as BarChart;
but as I mentioned, the minute I add the cloneBarChart as a child to
the tilelist container, the original barchart disappears from the
original tab.
I didn't include code cause its a bit spread out. I'm just wondering
if I'm missing some characteristic of the tab navigator or a
viewstack that makes hidden children inaccessible? It could be a
creation sequence problem but setting the selected index and
visibility should force creation, no?
thanks,
Danny
