Hi everybody,
I'm a new user of java3D and I have a poor english but I hope you will
understand my problem.
I use class KeyNavigatorBehavior for change my view, and for move some
object. When I start in application, theappletviewer of Kawa doesn't give
me problem. But when I start in applet (with file .html), if my mouse is in
the window when it appears, the keys (arrow) are inactive. My mouse must go
out and in for active arrow and KeyNavigatorBehavior.
But, in the same applet, I use the Rotate, Translate and Zoom mouse
behavior too. But, here, in the both case, mouse behavior work well: my
arrows are inactive, but I can move my object.
What I do wrong?? Why my mouse must go out and in of window for activate
arrow?? Do you have the same bug when you loading my applet??
The attach file give the code I did. Note that I want to use
VirtualUniverse with Locale object, and not SimpleUniverse.
Thank for your help.
Vincent
