Hello,
I'm currently working on a project which involves the creation of
a lot of compound widgets which act as the graphical interface to
a large suite of FORTRAN routines. I'm finding the widgets in IDL
very easy to handle and have produced what I think are good
results, but I do have one problem which I wonder if anyone else
has encountered (and perhaps knows a solution to?).
I find that when the value of a widget is updated using the
widget_control...set_value=... type construction the whole
compound widget seems to go through a convulsion as the
widget disappears and then reappears with its new value. This is
particularly noticeable when the compound widget is destroyed
and in some cases the effect can last for quite a while before
the widget disappears. The actual running of the program is
not affected in any way, but it makes the finished interface
look a lot less professional.
Is there perhaps a way of avoiding this that I haven't yet come
across?
Technical note: I am running IDL 3.6.1(c) on a DEC alpha (the problem
did not seem to be there for IDL 3.5.0 - perhaps because it ran
faster?).
Many thanks,
Tim Hammond.
