Hi,  
is it possible to set a rectangle FillPaint property to a gradient color by using an expression based on some variable values? (I’m using Ignition 7.8.0)

Thank you in advance

Hello,

You wouldn’t be able to use a binding directly but you could do something like this through scripting and then work this into an expression binding using the runScript() expression function.

```auto
from com.inductiveautomation.ignition.client.util.gui.paints import RelativeLinearGradientPaint
from java.awt import Color
from java.awt.geom import Point2D

#RelativeLinearGradientPaint(java.awt.geom.Point2D start, java.awt.geom.Point2D end, float[] fractions, java.awt.Color[] colors, MultipleGradientPaint.CycleMethod cycleMethod)
rlgp = RelativeLinearGradientPaint(Point2D.Double(0.0,0.5), Point2D.Double(1.0,0.5), [0.0, 0.4111675024032593, 1.0],[Color(255,0,0), Color(0,255,200), Color(0,0,255)], RelativeLinearGradientPaint.CycleMethod.NO_CYCLE)
event.source.parent.getComponent('Rectangle').fillPaint = rlgp
```

If you placed this script on a button it would change the gradient of a rectangle on screen to the specified colors and locations.

Let me know if this helps.

Best,

For Some reason it does not work to me.Could you please insert here the entire script included runScript() expression.
