Clarification needed: Material Design 3 styles in v21.18.0-alpha and missing Dialogs in v11.27.0-all

[tennisplatz924-prog]

Hello.

I am attempting to use this library for a small project but im having difficulty. I have read the documentation but seems like I'm still stuck.

I am using the following implementation: io.github.palexdev:materialfx:21.18.0-alpha (tried 11.17.0 as well)

UserAgentBuilder.builder()
    .themes(JavaFXThemes.MODENA)
    .themes(MaterialFXStylesheets.forAssemble(true))
    .setDeploy(true)
    .setResolveAssets(true)
    .build()
    .setGlobal();

Even with this setup, the controls appear to follow the Material Design 2 guidelines rather than Material Design 3. Could you clarify if M3 is the default in the 21.x branch or if a specific theme/token set needs to be applied to see the M3 look?

Missing Dialogs in materialfx-all:11.27.0
When I switch to io.github.palexdev:materialfx-all:11.27.0, the design actually looks M3, but the all package does not seem to include the Dialogs. Are Dialogs intentionally excluded from the all bundle, or is there a specific registration required for them in the 11.x UserAgentBuilder?

Note: The image shows how the buttons look using the materialfx non all package.

Environment:
Java Version: 25
OS: Windows 10
MaterialFX Versions tested: 21.18.0-alpha, 11.27.0, 11.17.0

Hello @tennisplatz924-prog
Version 21.x.x is for Material Design 2

If you want to try Material Design 3 you want to grab version 25.x.x, source is on the rewrite branch.
BUT! Beware that this version is work in progress, it's incomplete and offers only a few components. Do you have any idea of which controls you may need?

You can take a look at one of my side projects on how to import and use the newest versions.
Here are the Gradle config files: 1, 2
Check the versions on Maven though, they may be slightly outdated.

Here's how to add the themes: ThemeEngine

As for the dialogs, I'm not sure what could be the problem, I actually don't remember how they are handled on v21.

In v25 all kinds of popups (including dialogs) have been heavily reviewed. They are now part of the MFXCore module and they are generic, meaning that there are no pre-built recipes. Every popup has a content property, so you can set their view to whatever you want and of course style them however you want.
