I there an event which is fired everytime when a form becomes visible?
And which I can catch from inside the form. When the user switches away
from a form in my app, and later switches back, parameters may have
changed in the meantime so the form has to be reinitialized.
TIA,
Hans

Hello Hans,
Unfortunately there are no callback methods for the events you described.
You would have to implement it yourself. Take a look at the Displayable
isShown() method, maybe it can help you.

Thanks David, so i have to roll my own. Btw, I asked the wrong question.
It's all about a canvas, not a form as I wrote but I guess that doesn't
change much, right?
