# To subscribers of the xforms list from Jan Menzel <jmenzel@mail.desy.de> :
Hi all,
on displaying popup using fl_newpup(FL_ObjWin(ob)), fl_addtopup()
and fl_dopup from within a prehandler strange things are happening (on
i386 Linux with glibc2.1 and newest version of xforms):
a) redisplaying of main forms is stopped (e.g. slider value changes
from within fl_idle_callback() are not visible). If a fl_show_input() is
displayed as result of popup interaction, pressing e.g. the "clear" button
reenables the display-update again.
b) positioners updates (e.g. prosessing of FL_DRAW on switching displays)
are inhibited until any other interaction with the form has taken place.
The positioner is in a from within a tabfolder. On changing the active
folder, pressing any button, focussing an input field, pushing a choicer
or selecting a line within a browser reenables the positioner again. Also
pressing a mouse button within the positioner reenables updating it even
if it is currently not shown.
Sorry, I don't have test code for demonstrating this behavior,
execpt the application I'm currently working on, which shows all the
reported problems. On interest i could provide i via privat e-mail
(~150k).
Regards Jan
