In this post, I’ll be describing version 4 of JMetro, which has just been released.
JMetro is a Java, JavaFX theme inspired by Fluent Design. This version brings new styles to the following controls:
- Combo Box
- Scroll Bar
- Scroll Pane
These new styles are comprised of a new dark and light version.
JMetro 4.0 Details
I first started by updating the Combo Box.
Combo Box New Style
In this new Combo Box style, the colors and the down arrow image have changed:
Combo Box OLD JMetro Light Theme
Combo Box NEW JMetro Light Theme
You will notice here that the down arrow image has a thinner stroke and is wider. This is one thing that doesn’t happen in Fluent Design, but it happens with JMetro when you move the mouse over the Combo Box. Then, it immediately starts to open up to key presses from the keyboard. This is indicated by the focus indicator — the border of the Combo Box turns black (white in the case of the dark theme). Pressing the down and up arrow keyboard keys will now change the selected item. This is the default behavior of JavaFX.
You’ll notice above that JavaFX adds Scroll Bars when the Combo Box has more content. The first Combo Box is fine without the Scroll Bars, whereas the one below shows them for the user to be able to scroll through a larger content set.
Combo Box OLD JMetro Dark Theme
Combo Box NEW JMetro dark theme
Scroll Bar Style Change
Since I’ve changed the Combo Box style, I took the opportunity to update the Scroll Bar. I did this because, like I said, Scroll Bars can also be used inside Combo Box’s.
Scroll Bar OLD JMetro light theme
Scroll Bar NEW JMetro light theme
The colors are slightly different and the arrow has changed to one with a thinner stroke. The same is true of the dark style, with the arrow image color changing to white.
ScrollBar OLD JMetro Dark Theme
ScrollBar NEW JMetro Dark Theme
And the new Scroll Pane light and dark style:
ScrollPane NEW JMetro light theme
ScrollPane NEW JMetro dark theme
Version 4.0 of JMetro brings new styles to the Scroll Bar and the Combo Box. These control’s arrow images to be made thinner and wider. Colors from light and dark theme have also changed — just slightly.
Since version 3.0 came out a few weeks ago, 12 controls have been updated. This included new styles for controls that didn’t have them as well as refreshing, existing styles. Since there is a dark and light version for every control, that’s 24 new styles since the start of this last iteration!
With those 24 new styles, there are tons of small detail changes. They might seem tiny, but all of them add up to what can be an interface shine.
The versioning I’ve been adopting might seem a bit odd to you (and, maybe, it actually is) but my objective is, in version 5.0, to finish refreshing the looks of all the important controls. Also, I might add one or two new styles for controls that don’t have them, yet, and possibly a new feature that would allow changing the colors of the theme with a method call or through a CSS variable override.
I haven't updated the documentation page for Java, JavaFX theme JMetro. I'll be doing it in the near future.
