How do you pass constructor parameters using a builder like SwingBuilder?

Question

I want to access JFrame(GraphicsConfiguration) using SwingBuilder.frame(), but I can't set it via the attributes, since it's unavailable. How do you pass constructor parameters using the Groovy Builders?

UPDATE: As requested, including the solution. The value parameter for the FrameFactory.newInstance(builder, name, value, attrs) method is checked first to see if it's a JFrame itself. If not, it's ignored, and a new JFrame is created. It is then passed to a post-init method to handle the attributes.

This maps to the following syntax:

builder.name(value, attrs){}

where attrs is your map of attributes in the standard key:value format.

So, to complete with an example:

SwingBuilder swing = new SwingBuilder()
// pass the title to the valueFrame, even though we can pass as attr, for the example
JFrame valueFrame = new JFrame("Value Frame Title")
JFrame myFrame = swing.frame(valueFrame, 
                             pack:true, 
                             defaultCloseOperation:JFrame.DISPOSE_ON_CLOSE) {
  ... add your panels, etc here
}
assert myFrame == valueFrame

Answer 1

You should be able to pass in a JFrame as the value argument, according to the SwingBuilder.frame docs; maybe try that.
