absolute layout (x,y,w,h) looks different on Windows and Mac (windows wrong) about miglayout

This is because MigLayout uses logical pixels by default, which depend on screen DPI. Looking at the large Windows border in your screen shot, it seems that is uses larger DPI than your Mac.

If you want use real pixels, try

this.add(label, "x 0, y 0, w 250px, h 200px");

Or change the default unit to real pixels:

PlatformDefaults.setDefaultHorizontalUnit(UnitValue.PIXEL);
PlatformDefaults.setDefaultVerticalUnit(UnitValue.PIXEL);

You could also indicate that the size of a logical pixel should always be a real pixel with:

PlatformDefaults.setLogicalPixelBase( PlatformDefaults.BASE_REAL_PIXEL );

BTW would be interesting to know what Java version you use and the resolution of your screen.
Also a screenshot comparing a Java button with a native Windows button (to see any difference in size).

Thank you JFormDesigner :) After debugging through the code I found this PIXEL vs. LPX difference ;)

So after setting the default unit, everything works fine - in the same manner like MigLayout 4.

But is it a good idea to switch the default unit between ML4 and 5 from PX to LPX? It could be confusing for many people like me ;)

Thank you for your help. MigLayout is the best layout manager available. So I hope one day MigLayout is as popular as the built-in layout manager - or even better - will be integrated in the offiical JDK...

Best,
Tobi

btw: I used Java 1.8.0_60 and 1.6 on MacBook Pro Retina....1400x900 (@2x)

Integrated into the JDK... Hm, it is a recognition, but it would stifle any development.
