# To subscribers of the xforms list from Jan Menzel <jmenzel@mail.desy.de> :
Hi all,
i'm working on a application, which does interaction with itself
using a back ground process. (i was tolled thats called push/pull). The
application writes its changes to the back ground process and read it back
for displaying it in a form.
The readback is done using the idle callback. Now I discovered
some problems while using callbacks for interaction: main problem is, how
to handle the displaying of current settings, while the mouse is doing
interaction. For button and sliders evaluating "pushed" works good. For
browsers neigther "pushed" nor "belowmouse" does the trick. Any hints?
The second point it event, on which callbacks are called. I
noticed that callback are called on releasing either mouse buttons or
keyboard keys. Can that be changed to calling them when ever a press
occures or do i need to do that by hand using prehandlers?
Any hints?
Cheers Jan
