Hi,
This is aimed at the VMS community out there!!!!!
Is there a known bug using the sensitive=0 flag on a widget base under
OpenVMS?
For instance, the following code:
Pro my_test
tlb = widget_base(column=1)
my_base = widget_base(tlb, column=1, sensitive=0)
base2 = widget_base(my_base, row=1)
pulld = widget_droplist(base2, value=['aaa','bbb'])
widget_control, tlb,/realize
widget_control,my_base,/sensitive
end
When I run the above under OpenVMS 7.1 and IDL 5.4 and select the drop-down
list, each item is shown insensitive(greyed out). Surely this should be
sensitive (as per the penunltimate line). Furthermore, at this point the
X-system locks up. I can no longer size the screen, close it, minimise it.
All I can do is reboot - not exactly desirable.
Further investigation indicates that the software is expecting me to make a
selection, but this is not possible because they are greyed out. Hence the
systems is stuck on waiting for an event that can never occur.
I believe this is only a problem with VMS, as the same code runs as expected
on NT
I CAN work round it by not making my_base insensitive, but all the lower
widgets insensitive. However, in the real code, there is a large structure
of widgets (base,buttons,pull-downs,etc) under this base, and in order to
make them sensitive, I'd need to set each widget to sensitive individually -
messy and time consuming.
I would be grateful for any suggestions.
Regards,
Ian
