Select row on power table

Ignition
1

I’m try to read value from different column in a row of my powertable.
I have associated script to onclick event for power table, but every time i have a error.

Here my code:

ptable = event.source.getComponent()

selRow = ptable.selectedRow

if selRow > -1:
	idFer = ptable.data.getValueAt(selRow, "ID")
	print idFer
	system.tag.write("[Client]testtag",idFer)

somebody can explain me why?

Thanks

What is the error? I’m guessing it has something to do with getComponent(), which expects an argument. If this script is on the power table then simply using event.source will give you the power table object, no need to use getComponent. If you’re using an extension function then use ‘self.data’ to get the power table’s dataset.

Also, in the future you can add triple back quotes before and after your code blocks to format it nicely for the forum.

Thanks for your help

Extension methods aren’t events. They have no event object. Where you would use event.source in an event method, you must use self in an extension method. Also look at the the extension function signature (in the def line) for the other parameters supplied to the function.
