When I was writing that e-mail I was thinking about that, as I have some code that does something similar... so, my argument may be completely wrong... needs investigation.
Anyone from Adobe care to comment? Troy. On 4/21/07, Ronnie Liew <[EMAIL PROTECTED]> wrote:
Hi Troy, U mentioned that the parent Sprite (root of app) doesn't receive mouse events because bitmap as a child object doesn't count as a drawn hitarea. In that case, how come when i create a child sprite with a bitmap child, that child spirite does receive mouse events? Going by your argument, the child sprite would need a rectangular graphic drawn too.
