Blinking Table's cell

Ignition
1

Hi All,

I was wondering if there is a way to make a specific Power Table’s cell blink from let’s say… yellow to red with a blink time of 1 second.

Thanks in advance.
Cheers,

This was written by @JGJohnson in another post. This should be placed in the configureCell function of the power table. This should help point you in the right direction on what you need to do.

attributes = {"background": "#FFFFFF", "foreground": "#000000"}
    if rowIndex % 2 == 0:
        attributes["background"] = "#EEECE8"
	if colName == "val":
		if self.data.getValueAt(rowIndex, "writeable") == True:
			attributes["background"] = "#FFFF47"
	if colName == "alarm" and value is not None:
		attributes["text"] = None
	elif colName == "unit" and value is None:
		attributes["text"] = None
		if self.data.getValueAt(rowIndex, "alarm") is not None:
			attributes["iconPath"] = "CustomIcons/Indicator_Red.png"
			if value < 1:
				attributes["iconPath"] = "CustomIcons/Indicator_Green.png"

	return attributes

Has anyone tried something similar ? Can't understand the condition if value < 1:

trying to achieve a blinking cell where the dataset it coming from sql and only one cell value is live from OPC.

@JGJohnson , can help ?

It got messed up when dkhayes copied it. The line is actually

if value < 1:

As for blinking a cell, my first thought would be to add a couple of extra hidden columns to the dataset, so the data might look something like this:

MyCol, MyColBlinks, MyColBlinkState
value, True, 0

Then use a timer with a 1 second interval to update the dataset and toggle the blink state for any rows where MyColBlinks is set to True.

Then it's a simple matter of coloring the cell in the configureCell extension function according to whether or not the cell should blink and what it's blink state is.

if colName == "MyCol":
    if self.data.getValueAt(rowIndex, "MuColBlinks":
        if self.data.getValueAt(rowIndex, "MuColBlinkState":
            attributes["background"] = "#FF0000":
        else:
            attributes["background"] = "#FFFFFF"

Yes, great to know that I am on the correct path. Doing something similar.

Just created couple of custom properties and using the value from there as below,

Finally I found a really easy way to make a row blink:

  1. Put this function in project script, dont forget to import time on top of your project script
    image
  2. In configureCell function of a Power table, run this script: return Utilities.colorDelay2()

You got your row blinking with a interval of 1 second :wink:
