Close popup automatically after x seconds in Perspective

Ignition
1

Hi,

I'm trying to close a popup automatically after x seconds in Perspective.

So far I've tried the following script on the view's onStartup event:

def runAction(self):
	def closeLater():
		from time import sleep
		sleep(30)
		system.perspective.closePopup("")
	system.util.invokeAsynchronous(closeLater)

But this isn't very clean. If the popup is closed manually the script still runs.

Is there a proper way of achieving this?

Thanks

When you read your own script and find sleep() in there you're not thinking right. Don't!

  • Try creating a custom property on the popup view. e.g., viewOpenedAt.
  • Make the startup script write the time to the property. Something like,
    self.parent.custom.viewOpenedAt = system.date.now()
  • create another custom property, viewTimeout. Create an expression binding on it,
    (now() - {this.custom.viewOpenedAt}) > 5000
    This will turn true at 5000 ms.
  • Right-click on viewTimeout and create a change script. In this add your code to close the popup if the timeout is true.

I haven't tested this. You may need to reset the timeout before you quit so it's ready for the next use.

What Transistor said, but i'd use an expression binding on viewOpenedAt:

now(0)

I don't like to use sleep() either. The code is inspired from this answer from @cmallonee on another post.

Thank you @Transistor and @josborn for the proposed alternative.

The finally working setup of the view's custom properties is:

  • viewOpenedAt
    • Binding: now(0)
    • Persistant: false
  • viewTimeout
    • Binding: (now() - {this.custom.viewOpenedAt}) > 30000
    • Change Script:
def valueChanged(self, previousValue, currentValue, origin, missedEvents):
	if currentValue.value == True:
		system.perspective.closePopup("")

A working view example:
