Confirmation pop up on Numeric text field

Ignition
1

Hello,

I need to have a ‘Are you sure’ pop up on numeric text field before the operator can actually enter values. I know it could be done by system.gui.confirm, but could someone please help me with the correct script for it?
Also what will happen if the operator chooses no ? will the pop up disappear and go back to the numeric text field for the operator to click on it again?

Thanks

In that example code they are using system.db.runupdatequery which I dont need in my case. When I delete that code and just keep system.gui.confirm, it gives me an error. Could you please help me further? I am new to python coding.

Oops, I didn’t read your question correctly. I’m not 100% sure on the best method for that. Maybe use system.gui.inputBox instead.

Add a custom property holding the previous value (my example is prevValue).

In a propertyChange script:

if event.propertyName == 'value':
	if event.source.value != event.source.prevValue:
		if system.gui.confirm("Are you sure?"):
			event.source.prevValue = event.newValue
		else:
			event.source.value = event.source.prevValue

EDIT: almost but not quite. I’d perhaps add one more custom property as a control value and write to that. There’s no way to intercept the value before being written to say, a tag. using a control value will help with that.

I am still finding it hard to understand. Do you mean adding custom property on the text field?
Here is what I am trying to do

So every time the operator clicks on that numeric field box, a confirmation pop up should appear.
