Yes I know I should be using the Internal Designer, but I'm working with a legacy Scene Builder layout.
I would like to programmatically adjust some of the "Transform" parameters of an AnchorPane which are available in Scene Builder, but not exposed in B4J:
Specifically I would like to programmatically adjust Scale X, Scale Y and Translate Y.
You should be able to use the JavaObject library to achieve what you want.
B4X:
Dim anchorPaneJO as JavaObject = yourAnchorPane
anchorPaneJO.RunMethod("SetScaleX",array(2.0d)) ' 2.0d as it wants a double
...
anchorPaneJO.RunMethod("setTranslateY",array(100.0d)) ' translate it +100
