I have already posted this in the Flex 2 forum with no
response, so I thought I'd try here too...
I have created a form in Flex 2.0.1 and when the user clicks
the "Continue" button, I want to save the form as BitmapData, then
encode into JPG data. However, I would like to make some of the
components invisible first so they don't render, and disappear from
the screen while this is happening. I would also like a busy cursor
show while this is happening, as at the moment, the application
looks like it freezes for a few seconds, then continues to the next
page. The capture however does happen correctly, and the hidden
components are not captured
The problem is that no matter what I do, the items stay on
the screen while the BitmapDatais captured, and the busy cursor
never displayes. I have the following code:
The actual capturing of the bitmapdata etc works perfectly,
and in the captured image itself, the controls set to visible =
false are not captured. However, while the data is being captured,
the items are still displayed on the screen, and the busy cursor
never displays. While this is happening, it looks as though the app
is doing nothing, as the user can still move the mouse around the
screen, although the cannot interact.
Can anyone shed some light on how to achieve this? I just
need, at the very least, an indication to the user that SOMETHING
is going on behind the scenes.
