B4J Question How to dynamically determine height of 'Label' control (with WrapText property set to True) based on its current Text contents?

[m4.s]

Of course, factoring in the Label's defined/set Font size too.

well... i am using that... ...i always add some dips at the result to be sure...

Sub MeasureMultilineTextHeight (Font As Font, Width As Double, Text As String) As Double
    Dim jo As JavaObject = Me
    Return jo.RunMethod("MeasureMultilineTextHeight", Array(Font, Text, Width))
End Sub

#if Java
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import javafx.scene.text.Font;
import javafx.scene.text.TextBoundsType;
public static double MeasureMultilineTextHeight(Font f, String text, double width) throws Exception {
  Method m = Class.forName("com.sun.javafx.scene.control.skin.Utils").getDeclaredMethod("computeTextHeight",
  Font.class, String.class, double.class, TextBoundsType.class);
  m.setAccessible(true);
  return (Double)m.invoke(null, f, text, width, TextBoundsType.LOGICAL_VERTICAL_CENTER);
  }
#End If
