FlatLaf dark and light look and feels

[DevCharly]

(crosspost of ​https://forum.openstreetmap.org/viewtopic.php?id=69029)

Hello,

I'm the author of the FlatLaf look and feel (​https://github.com/JFormDesigner/FlatLaf)
and wanted to ask whether the JOSM community is interested in using FlatLaf in JOSM.

FlatLaf is a new modern open-source L&F that looks similar to Darcula/IntelliJ
themes you maybe know from IntelliJ IDEA. It comes with dark and light themes,
supports 3rd party IntelliJ themes, scales on HiDPI displays, runs on all
platforms (Windows, Linux and macOS), uses Mac platform specific key bindings on
macOS and is easy to integrate into existing Swing applications.

While FlatLaf is still young, there are already a lot of applications using it.
Most prominent is NetBeans 11.3.

Here are some screenshots of JOSM running with FlatLaf:

If there is interest in using FlatLaf in JOSM, I'm willing to integrate it,
fix FlatLaf related issues and submit SVN patches.

JOSM with FlafLaf Dark requires some minor color adjustments where hardcoded
colors are used in JOSM UI components.

I'll attach the patch used to create the screenshots to this ticket.

Thanks,
Karl

The JAR file is 290 kB -- ​https://mvnrepository.com/artifact/com.formdev/flatlaf/0.28

It might be a good candidate for a plugin.

Long years we had the plastic_laf, maybe that can be used as base for a new plugin. I also think this is good as plugin. It's nothing for the core.

plastic_laf plugin has been archived here: ​https://svn.openstreetmap.org/applications/editors/josm/oldplugins/plastic_laf/

[DevCharly]

OK, then I'll create a plugin.
Thanks for the link to the plastic_laf plugin.

​[o35482] - see #josm19027 - Add flatlaf plugin

However, due to r16498, even the early plugins are loaded too late (since setupUIManager is called before). I'm unsure when to load LaF plugins – ideally those would be loaded even early (before setupUIManager)…

[skyper]

Plugin does not show up under Plugins, yet.

[skyper]

I`d like to test the plugin but it is not listed under Plugins and therefore not available under preferences.

Is there something missing ?

[simon04]

Due to the problem mentioned in comment:5 (see also: ticket:19290#comment:5 et seq.), I haven't build a flatlaf.jar yet.

How do I set the look and feel after installing the plugin? I can't find anything new in the preferences under wiki:/Help/Preferences/Display#LookAndFeel or somewhere else.

I got it working by setting the proper value in advanced preferences for laf. Values are described ​here.

Guess a proper Gui integration to have the four values listed together with the default ones under Display Settings -> Look and Feel is needed.

Thx, that worked.

Yes that would be useful. Can you add that Simon?

[DevCharly]

Have not tried it, but I think the recent change in [35535/osm]
is responsible for not showing FlatLaf in the UI.

Those FlatLaf.install() methods invoke UIManager.setLookAndFeel(),
but invocation of UIManager.installLookAndFeel() is needed to show FlatLaf in the list of available LaFs in the UI.

[simon04]

In 35541/osm:

see #19027 - Use UIManager.installLookAndFeel

In 35542/osm:

see #19027 - dist flatlaf.jar

@DevCharly, thanks for your invesitations. Should be fixed now (after updating the plugin).

JOSM running with GDK_SCALE=3 (HiDPI w/ 300%) and FlatLaf Light is a piece of art. :-)

The dark mode is great!

One thing I noticed: The text in the status bar is nearly unreadable which can be seen in the third screenshot of the ticket description.

Yes, thanks for this plugin.

One thing I noticed: The text in the status bar is nearly unreadable which can be seen in the third screenshot of the ticket description.

Think all background colors, except blue, of boxes like in relation manager and history viewer could be darker at least two of the three colors. Would prefer a darker red and yellow/orange leaving the green lighter for color-bind users.

The blue links are hard to read too, imho. See preferences -> plugins or the help browser.
