MigPane sizing not properly

[GoogleCodeExporter]

What steps will reproduce the problem?
Run attached source

What is the expected output? What do you see instead?
MigPane doesn't handle properly the pane sizing, in fact it should match with 
the button's preferred size (like HBox or similar layouts in FX). Instead the 
pane is more little than the button (see screenshot).

What version of the product are you using? On what operating system?
Linux 3.2.0, JRE 1.7.0_45-b18, MigLayout (MigPane) 4.2

This is not a bug, what you are seeing is MigLayout's default attempts to make 
a UI look good byh adding white space. Try creating MigLayout like this:

MigPane root = new MigPane(new LC().insets("0px"));

I'm sorry, I've read you issue wrong.

Ok, interestingly enough MigPane seems to be doing it fine, below are some 
debug prints:

MigPane.setPrefHeight 14.0
MigPane.setPrefHeight 35.0
Button[id=null, styleClass=button] FX2ComponentWrapper.setBound x=7,y=7 / 
w=28,h=21 / resizable=true
MigPane.setPrefHeight 35.0
Button[id=null, styleClass=button] FX2ComponentWrapper.setBound x=7,y=7 / 
w=102,h=21 / resizable=true

The first time setPrefHeight is called, it is set to just the insets (2x7px). 
Later on the button is added (21px) and the prefheight is set to 35px. For some 
reason the window does not pick that up. If I hardcode the prefHeight to 35, so 
the first call also sets 35px, then the window sizes correctly.

Strange

So it's a problem concerning JavaFX that doesn't update the window size, 
MigLayout, or both?

I have found a workaround for this. Maybe it's not a "correct" way, but a 
temporary solution would be to append 

stage.sizeToScene()

after

stage.show()

I found the problem, it was a matter of when MigPane recalculated its size and 
when JavaFX wanted to know it.

Sweet! :-)
Will it be fixed in a near future release? And can we already have a patch to 
apply to the current release or is it too early to ask?

It is already fixed, in the 5.0-SNAPSHOT

Where can I find the 5.0 snapshot?

Good work, Thanks for the fix. Fixed my issues

I downloaded snapshot 5.0 from:
https://oss.sonatype.org/content/repositories/snapshots/com/miglayout/

I tried the version 5.0, but it's not working with Java7. I get the next 
exception: Caused by: java.lang.UnsupportedClassVersionError: 
org/tbee/javafx/scene/layout/fxml/MigPane : Unsupported major.minor version 52.0

I understand that version 52.0 means Java8, isn't?

Is there a solution for Java7?

5.0 is Java 8, MigPane 4 is for Java 7. I would suggest upgrading to J8, since 
JavaFX  also is a major upgrade.
