panel setHeight() extremely slow

[smerny]

responseContainer.setHeight(rowCount * 420);
responseContainer.doLayout();

it's taking several times (probably 10x) longer to load than if i remove the setHeight line.

without the setHeight, the cmp's within this container overflow off the container.

why does it take so long? is there an alternative (quicker) way to do this?

Not sure why you are using setHeight... If you don't use a layout manager, the items should make the container auto height. If you do, then you should use scrolling. The doLayout will make the container redo the layout of all the items.

deviceTabPanel (sencha TabPanel) contains items that have scroll: 'vertical'... one of which is responseContainer

responseContainer contains a sidebar and a contentContainer (sencha panel).

contentContainer is populated by rows (sencha panels) of 3 components (sencha panels)

if i include the setHeight like in my first post, it works as desired but takes forever to load.

if i exclude the setHeight, it loads faster but the content within contentContainer flow off the responseContainer and i am unable to scroll to overflowing rows.

i'm making the content independently scrollable and putting the doLayout on that and it seems to work well. thanks
