Hello
all.
I have an OPI that sends some
data to Stream Device records that are connected to an
equipment using serial RS232. This operation is started with a button
press. I don't want this button to be pressed again while the data is
being transfered to my equipment. So, I tried to disable the button in the
beginnig of the script, and reenable it at the end. But what I see is
an enabled button until the end of the data transfer. Only at the end of the
script I can see a quick transition of the button to disabled state and again to
enabled.
Between each data I need to
transfer, I use time.sleep, because my equipment need some time to
process the data before receiveing the next one.
My python script is the
following:
(...)
button = widgetController.getWidgetModel() button.setPropertyValue("enabled", False) button.setPropertyValue("text", "Programming\nPlease, Wait") (data transfer code, with some time.sleep functions...)
button.setPropertyValue("text", "Program Furnace") button.setPropertyValue("enabled", True) Is there a way to force the OPI refresh, as
the disabled status of the button is shown?
Thanks,
