IllegalArgumentException: No interpolator found for float during implementing Substance LAF

Question

I have tried to implement Substance LAF. I have also downloaded Trident library. Application will normally start (with LAF chosen from package structure) but when I try to used menus in JMenuBar I get exception below.

I have found very similar problem but it is definitely something different – Flamingo ribbon: Java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float.

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException:     No interpolator found for

Any ideas?

Answer 1

I have found the solution to this, after some good hours. The error

java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float

has nothing to do with the code in the TimelinePropertyBuilder class. It is instead missing the trident-plugin.properties file in the META-INF of the respective top-level library. There exactly are being defined the Interpolator classes sources.

So instead of looking for it, here is the so much needed trident-plugin.properties:

UIToolkitHandler=org.pushingpixels.trident.swing.SwingToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swing.AWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.swt.SWTToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swt.SWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.android.AndroidToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.android.AndroidPropertyInterpolators

PropertyInterpolatorSource=org.pushingpixels.trident.interpolator.CorePropertyInterpolators

This should sort it out.
