Numeric stepper in perspective

Ignition
1

Hello!

I´m trying to replicate a numeric control with stepper up and down
image

To do so I added a NumericEntryField and 2 buttons on the side. All inside of a container.

In the container I created a custom property:
image

wich I bind from the NumericEntry Field
image

and in the decrease buttons I added a script event onclick

def runAction(self, event):

def runAction(self, event):
  currentValue = parent.custom.currentValue
    if currentValue > 0: 
        parent.custom.currentValue = currentValue - 1

and on the increase buttons I added a script event onclick

def runAction(self, event):
    currentValue = self.view.parent.custom.currentValue
    self.view.parent.custom.currentValue = currentValue + 1

NOne of the versions, with
parent.custom.
or
self.view.parent.custom

working

But I may missing something because is not working. Any ideas welcome.

Is your NumericEntryField binding bidirectional?

You can simplify your code:

def runAction(self, event):
    if parent.custom.currentValue > 0: 
        parent.custom.currentValue -= 1

Tip: as mentioned before, show the window title on your binding screenshots so we can see what exactly you are binding.

Also, the indentation is not correct on the first runAction script.

Sorry, error in my code. It should be,
if parent.custom.currentValue > 0:
Fixed.

I can't see any errors in your configuration.

Tips:

  • Always use onActionPerformed rather than onClick. onClick will execute even if the button is disabled. onActionPerformed doesn't.
  • Don't give your user options that won't work. On Button_1's props.enabled create an expression binding,
    parent.custom.currentValue > 0
    Now you don't need the if parent.custom.currentValue > 0: in your event script.
  • Do something similar with the Button_0.
  • Make sure that the button style changes when not enabled.

I think the problem is you have left out self.

def runAction(self, event):
	self.parent.custom.currentValue -= 1

Use the Browse Properties button in the script editor to avoid this kind of error.
