B4J Question Forms Builder Obsolete?

[Jim McDougal]

I'm trying to run Forms Builder in B4J with Java\jdk-11.0.1\bin\javac.exe and I get the following error response:

Main - 67: Undeclared variable 'r' is used before it was assigned any value.
Main - 66: Undeclared variable 'r' is used before it was assigned any value.
Main - 65: Unknown type: reflector
Are you missing a library reference?

And the error in:

Sub AddKeyPressedListener
Dim r As Reflector
r.Target = MainForm.RootPane
r.AddEventHandler("keypressed", "javafx.scene.input.KeyEvent.KEY_PRESSED")
End Sub

Any thoughts on what might be causing this? Both B4J and Forms Builder are new downloads.

I posted this to an old thread (mea culpa) and was advised that Forms Builder was deprecated years ago, however it is the tool demonstrated in the Forms and User Input video tutorial and the Forms Builder source code is only dated Sep 2019 (perhaps that is old, I don't know).

You are talking about
[B4X] Forms Builder
? This one is not deprecated.

The deprecated one is FXSceneBuilder

Working with JavaFX Scene Builder

This is an old and irrelevant tutorial.

Sorry, i did interpret your other post wrong.

Just to clarify (I haven’t seen your other post). Are you talking about the forms builder in the pint 1?

[B4X] B4XPreferencesDialog - Cross platform forms

B4XPreferencesDialog makes it easy to create dialogs with all kinds of input fields. The main steps required to use these dialogs are: 1. Define the list of fields. The recommended way to do it is with Forms Builder tool...

Yes, the Forms Builder used with B4XPreferencesDialog.

My other post is identical to the one beginning this thread:

And here's the compile error:

B4J Version: 8.90
Parsing code. Error
Error parsing program.
Error description: Unknown type: reflector

Thanks.

Just select ( = import) the jReflection library:

It looks like you haven't downloaded the reflection library. Download the file from the first post in the link, unzip it and copy the jar and xml to your additional libraries folder.

Voila! I passed on that post previously since it was 8 years old, but that fixed it. Thanks.
