Image loading external content won't have a useful size at the time things

you want the viewstack to change in size? I think resizeToContent=true will
do that. If you can know ahead of time the size you want, setting that on
the viewstack would be better (and you'd save on the overhead of
Hi thanks for your reply. As the hbox gets populated i need it to resize itself. Once each hbox has been populated with the images I attach a function to the viewstack which allows me to scroll the hbox with mouse position - so it scrolls horizontally depending on where the mouse is in relation to the viewstack. So as you can see I need by this point for each hbox to have resized in order to correctly calculate my scrolling function. The bizarre thing is the selected Index hbox displays all the images but the rest of the hboxes takes on the same width as this one and this is a problem because some of my other hbox contains more images. As a test I set the selected Index of the viewStack to be the third Hbox, then I restarted the application and now all the hbox takes on the wdith of this one. I am creating a library of thumbnails which is dynamically driven. It's not possible for me to predetermine the width of each. Do you have any suggestions for this?
