My personal choice is to remove all reflection from the code but sometimes its not possible 🙂

I've also used this library. I don't think it uses true Java Reflection and is just file I/O operations http://static.javadoc.io/org.reflections/reflections/0.9.10/org/reflections/Reflections.html

SpreadsheetView needs a lot of TornadoFX love. I started to work on it and have a vision to declare different sections of the spreadsheet using a DSL. It's a pain though trying to juggle all these indices and getting the GridBase managed correctly. https://github.com/edvin/tornadofx-controlsfx/blob/spreadsheetview/src/test/kotlin/tornadofx/controlsfx/testapps/SpreadsheetView.kt

What I'm trying to accomplish is copycatting the idioms from

TableView

that worked so well, and build different sections of the Spreadsheet using that

TableView

idiom.

@edvin that looks like you have some javafx jars on the classpath and others on the module path

i don't think that error looks reflection related

i've seen it when i've tried to pull in classes from other JARs that aren't loaded

(java 8)

if the jars are all on the module path, there should be exports between them already for cases where they need to access internal apis between each other

yeah but that's a java 11 error

modules related

what's the command line being used?

@abhinay I tried, now it complains about "Unknown module: javafx.controls specified to --add-exports", but I've added a

requires javafx.controls

line to my

module-info.java

. Seems like it's not picking it up. Hopefully this can be described in the build system somehow, we can't expect users to add all this gibberish to the command line to run apps 😞

does that get added to a manifest like osgi?

@mikehearn Aha, OK. I need to read up on the module system from the beginning, I'm missing the full picture here 🙂

@mikehearn I have the javafx dependencies listed in the Maven deployment descriptor, and in addition I have requires statements for the modules in module-info.java. Is that not how it's supposed to be set up?

This is what I did initially: https://openjfx.io/openjfx-docs/#maven

That works for "hello world", but without

module-info.java

I get errors like "java.lang.IllegalAccessError: superclass access check failed: class com.sun.javafx.scene.control.ControlHelper (in unnamed module @0x4f638935) cannot access class com.sun.javafx.scene.layout.RegionHelper (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.scene.layout to unnamed module @0x4f638935" when I try to create a View

what is the java command line being run?

I've been trying a lot of things, right now it's:

-.kt

yeah so you are mixing classpath and module path

that's on the classpath

but

those are on the module path

all the javafx modules need to be on the module path

now the question is - where did this command line come from, and how did you end up with this mix?
