I'm implementing the function with javaobject but there are same problems

B4X:

Private shadow as JavaObject
shadow.InitializeStatic("javafx.scene.effect.DropShadow")
shadow.RunMethod("setRadius", Array As Object("5"))
shadow.RunMethod("setOffsetX", Array As Object("3"))
shadow.RunMethod("setOffsetY", Array As Object("3"))
shadow.RunMethod("setColor", Array As Object("0, 0, 0"))
........

java.lang.RuntimeException: Method: setRadius not matched.
and also SetOffsetX ecc.
where I'm wrong?
Thanks

DropShadow will not add the shadow to the text. It will add it to the whole field.

About the JavaObject code. The types must be double:

B4X:

Dim offsetX = 3, offsetY = 3, radius = 5 As Double
shadow.RunMethod("setRadius", Array(radius))
...

Color is a bit more complicated. Just remove that line.

Ther's an article on oracle doc:

B4X:

https://docs.oracle.com/javafx/2/text/jfxpub-text.htm

Drop Shadow Effect
To implement a drop shadow effect, use the DropShadow class. You can specify a color and an offset for the shadow of your text. In the TextEffects application, the drop shadow effect is applied to the red text and provides a three-pixel gray shadow. You can see the code in Example 15.

Example 15

DropShadow ds = new DropShadow();
ds.setOffsetY(3.0f);
ds.setColor(Color.color(0.4f, 0.4f, 0.4f));

Text t = new Text();
t.setEffect(ds);
t.setCache(true);
t.setX(10.0f);
t.setY(270.0f);
t.setFill(Color.RED);
t.setText("JavaFX drop shadow...");
t.setFont(Font.font(null, FontWeight.BOLD, 32));

You are correct. It will show the text shadow for a Label.

Ok, now where i wrong?
About the JavaObject code as you suggested:

B4X:

shadow.InitializeStatic("javafx.scene.effect.DropShadow")
Dim offsetX = 3, offsetY = 3, radius = 5 As Double
shadow.RunMethod("setRadius", Array(radius))
shadow.RunMethod("setOffsetX", Array As Object(offsetX))
shadow.RunMethod("setOffsetY", Array As Object(offsetY))

Line 19 java.lang.IllegalArgumentException: object is not an instance of declaring class...(shadow.RunMethod("setRadius", Array(radius)))

The next version of B4J will allow you add shadows with the designer.

You need to use InitializeNewInstance instead of static.
