Doesn't sound like you've tried too hard.  But then some people hate
ANYTHING new.  I heard the same thing about Swing.

May I ask why you think that?

The core concepts of JavaFX have been seen working successfully
in Adobe Flex, Microsoft Silverlight and web.

The foundation seems solid.

Is it lacking maturity or?

Java does not have any major market share in desktop apps and
it seems very unlikely that JavaFX will change that. It has been out
(since 2.x) for some years now and no indication of change.

Java's future seems solid centered around Java EE, Android and
big data.

Yes, but Java is big on IOS and Android devices and Oracle is pushing
Java FX for those, especially web-based apps.

Oracle is not pushing JavaFX to iOS and Android. In fact they removed
support for JavaFX  on ARM.

Those that would want to get that working will need to use
various third party components.

For now, yes. But it was slow and buggy.  I expect them to bring it back
in the future.

You can easily scale the entire window after the screen size.

And most parts would scale with the window.

It is text that is causing you problems?

The fonts are really small but that can be fixed pretty easily.  It's 
the frame and dialogs that are really small that can't easily be 
corrected.  Using the windows system laf helps some but you still have 
to adjust the font sizes.  I actually surprised there isn't some way to 
do it automatically with the Nimbus laf but there apparently isn't.

If you set the font size, use layout manager and do a pack wouldn't
everything scale?

I think I am missing something.

Well it only works with the Windows LAF for starters.  The simple 
program I'm trying to get to work has a JOptionPane dialog and the icon 
shows extremely small.  Multiplying the font size by a factor of the new 
window size divided by the old window size gives a wildly too large 
font.  So for the moment I'm going to increase the font size and later 
rewrite it in FX.  Another wrinkle is that I can't figure out how to get 
a desktop link to add the required command line switches to java.exe to 
switch the LAF.  I'm going to have to code it in.

This is going to become more of a problem in the future as physically 
small screens (mine is an 11 inch laptop) have very high pixel counts 
(mine is 3200x1800).  I have a large Swing app running on a Windows 
machine with a physically large screen with about the same pixel count 
and the customer is complaining about the size of the type.  After what 
I've discovered playing with this we may have to run that program with 
the Windows LAF instead of the default to get it to scale better.

It's disappointing that at this late stage of the game that Swing 
doesn't have some sort of adjustment for high DPI displays.  But maybe 
they want us to move to FX?

If you are worried about the future why not create a browser based  user 
interface? That is by far the easiest way to get a responsive and 
scalable UI across the various screen sizes and resolutions.

Like an Applet?  This started with a simple program that needs to 
read/write a file to the local file system.  I don't think you can do 
that with a browser based app?

Really high DPI monitors are coming, something has got to give somewhere.

I think for now anyway it is going to be much less work to learn JavaFX.

No, not an Applet. I used invisible applets in stead of JS in my early 
AJAX-avant-la-lettre days before JS had XHR. But for the rest I never 
liked the Applet concept.

Reading/writing local files would indeed be a challenge. But if it is a 
simple file-in/file-out thingy than I usually opt for a web-app with an 
upload/download mechanism. Really basic stuff.

I can hardly remember the days when I used to worry about distributing 
an application, let alone a users OS, Java version, etc. You would be 
really hard pressed to get me to go there ever again. JavaFX is a dead end.

javaw -Dlaf=whatever ...

and:

UIManager.setLookAndFeel(System.getProperty("laf"));

?

     Haven't tried it myself, but this should be possible without code
changes.  From the Tutorial:

	If the program hasn't successfully specified a L&F, then the UI
	manager uses the L&F specified by the swing.defaultlaf
	property. [...]

... so -Dswing.defaultlaf=whatever should suffice ...

	[...] If the property is specified in both the swing.properties
	file and on the command line, the command-line definition takes
	precedence.

... so editing swing.properties would be an alternative (but would
affect the L&F of *all* applications that don't set their own).

Nice. I did not know about that one.

How do you set the font size?

The following works for me:

import java.awt.BorderLayout;
import java.awt.Toolkit;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.SwingUtilities;
import javax.swing.UIDefaults;
import javax.swing.UIManager;
import javax.swing.plaf.FontUIResource;

public class FontSizing extends JFrame {
	private static final long serialVersionUID = 1L;
	private void setFontSizePoints(int siz) {
		UIDefaults def = UIManager.getLookAndFeelDefaults();
		Object[] keys = def.keySet().toArray();
		for(Object key : keys) {
			if(def.get(key) instanceof FontUIResource) {
				FontUIResource fnt = (FontUIResource)def.get(key);
				def.put(key, new FontUIResource(fnt.getFontName(), fnt.getStyle(), 
siz));
			}
		}
	}
	private void setFontSizeInches(double siz) {
		int dpi = Toolkit.getDefaultToolkit().getScreenResolution();
		int pt = (int)(siz * dpi);
		setFontSizePoints(pt);
	}
	public FontSizing() {
		setFontSizeInches(0.75);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		getContentPane().setLayout(new BorderLayout());
         setTitle("Font Sizing");
         JButton test = new JButton("Test");
         test.addActionListener((ev) -> 
JOptionPane.showMessageDialog(FontSizing.this, "It works"));
         getContentPane().add(test,  BorderLayout.CENTER);
		pack();
	}
	public static void main(String[] args) {
         SwingUtilities.invokeLater(() -> (new 
FontSizing()).setVisible(true));
	}
}

I don't think desktop is a priority at all.
