RE: Dynamically change file in embedded screen

[CHOQUET Antoine via Tech-talk <tech-talk at aps.anl.gov>]

Hello,

Here is an embedded python script that I use on an embedded display to update the file path:

"""

from org.csstudio.display.builder.runtime.script import PVUtil

channel = PVUtil.getString(pvs[0])

#Reload window
widget.setPropertyValue("file", "")
widget.setPropertyValue("file", channel)

"""

Then I use action buttons to write the path of the file to be opened in the embedded display. The action button writes the path as a string to a local pv, which the script above retrieves with pvs[0] (the script is triggered when the PV value changes).

Best Regards,

Antoine Choquet.

Objet : Dynamically change file in embedded screen

 

Hi all,

 

is it  possible in Phoebus to dynamically change the file loaded in an embedded display?
I tried to create a display with an action button and an embedded display; the "file" field of the embedded display is a pv whose value is overwritten by clicking on the button.
This however doesn’t seem to work.

 

Best regards,
