Highlights

Custom window decorations

Custom window decorations (Windows 10 only) support dark window title panes and embedding menu bar into window title pane.

Native Windows 10 borders and behavior are used when running in JetBrains Runtime 11 or later (the JRE that IntelliJ IDEA uses):

To use custom window decorations in your application, enable them with following code (before creating any frames or dialogs).

JFrame.setDefaultLookAndFeelDecorated( true );
JDialog.setDefaultLookAndFeelDecorated( true );

Then, if running on Windows 10, custom window decorations are used and the menu bar is automatically moved into the title pane. On other platforms or older Windows versions, the custom window decorations are not used.

Filled check boxes and radio buttons

It is now easy to use "filled" style check boxes and radio buttons in any FlatLaf theme (as already used in IntelliJ theme):

Enable with:

UIManager.put( "CheckBox.icon.style", "filled" );

  support:
  • dark window title panes

0.34

Highlights

This release brings a complete rewrite of menu item layout with stable left margins, right aligned accelerators (as in Windows and macOS) and larger gap between text and accelerator. The text and accelerator are no longer layouted in "columns", which makes menu width smaller.

Also a new "underline" menu selection style is now available:

Can be enabled with:

UIManager.put( "MenuItem.selectionType", "underline" );

Change Log

• Menus: New menu item renderer brings stable left margins, right aligned
  accelerators and larger gap between text and accelerator. This makes menus
  look more modern and more similar to native platform menus.
• New underline menu selection style that displays selected menu items similar
  to tabs (to enable use UIManager.put( "MenuItem.selectionType", "underline" );).
• Menus: Fixed text color of selected menu items that use HTML. (issue #87)
• Menus: On Windows, pressing F10 now activates the menu bar without
  showing a menu popup (as usual on Windows platform). On other platforms the
  first menu popup is shown.
• Menus: On Windows, releasing Alt key now activates the menu bar (as
  usual on Windows platform). (issue #43)
• Menus: Fixed inconsistent left padding in menu items. (issue #3)
• Menus: Fixed: Setting iconTextGap property on a menu item did increase left
  and right margins. (issue #54)
• Hide mnemonics if window is deactivated (e.g. Alt+Tab to another
  window). (issue #43)
• macOS: Enabled drop shadows for popup menus and combobox popups. (issue #94)
• macOS: Fixed NPE if using JMenuBar in JInternalFrame and macOS screen menu
  bar is enabled (with -Dapple.laf.useScreenMenuBar=true). (issue #90)

0.33

Highlights

Improved disabled grayscale icons:

Note: Using this release in NetBeans 11.3 (and older) shows an "cannot find symbol" error in the NB editor for look and feel classes like FlatLightLaf or FlatDarkLaf. This will be fixed in NetBeans 12 Beta 4. Either ignore the error, because build and run project still works, and update to NB 12 later. Or pass a string to UIManager.setLookAndFeel("com.formdev.flatlaf.FlatLightLaf");.

Change Log

• Improved creation of disabled grayscale icons used in disabled buttons, labels
  and tabs. They now have more contrast and are lighter in light themes and
  darker in dark themes. (issue #70)
• IntelliJ Themes: Fixed ComboBox size and Spinner border in all Material UI
  Lite themes and limit tree row height in all Material UI Lite themes and some
  other themes.
• IntelliJ Themes: Material UI Lite themes did not work when using
  IntelliJ Themes Pack addon. (PR #88, issue #89)
• IntelliJ Themes: Added Java 9 module descriptor to
  flatlaf-intellij-themes-<version>.jar.
