3.4.1

Change Log

Fixed bugs

• SplitPane: Update divider when client property JSplitPane.expandableSide changed.
• TabbedPane: Fixed swapped back and forward scroll buttons when using
  TabbedPane.scrollButtonsPlacement = trailing (regression in FlatLaf 3.3).
• Fixed missing window top border on Windows 10 in "full window content" mode. (issue #809)
• Extras:
  • FlatSVGIcon color filters now support linear gradients. (PR #817)
  • FlatSVGIcon: Use log level CONFIG instead of SEVERE and allow
    disabling logging. (issue #823)
  • Added support for JSplitPane.expandableSide client property to FlatSplitPane.
• Native libraries: Added API version check to test whether native library
  matches the JAR (bad builds could e.g. ship a newer JAR with an older
  incompatible native library) and to test whether native methods can be invoked
  (some security software allows loading native library but blocks method invocation).
• macOS: Fixed crash when running in WebSwing. (issue #826; regression in 3.4)

Incompatibilities

• File names of custom properties files for nested Laf classes now must include
  name of enclosing class name. E.g. nested Laf class IntelliJTheme.ThemeLaf
  used ThemeLaf.properties in previous versions, but now needs to be named
  IntelliJTheme$ThemeLaf.properties.

BTW if you'd like to support the FlatLaf open-source project, please consider sponsoring it. Thank you very much for doing so.

Highlights

"full window content" mode for FlatLaf window decorations (Windows 10/11 and Linux)

Full window content mode allows you to extend the content into the window title bar. This means that the content pane (and glass pane) of the Swing window is extended into the window title bar. The window icon and title are automatically hidden. Only the minimize/maximize/close buttons stay visible. So your application can use (nearly) the whole window area.

You can try out "full window content" mode in FlatLaf Demo.
Press the "expand" button on the right side in the tab area.

macOS: window title bar close/minimize/zoom buttons spacing

If using full window content mode on macOS, it is now possible to use larger space
around the close/minimize/zoom buttons (traffic lights) to give your application a "native" look:

Change Log

New features and improvements

• FlatLaf window decorations (Windows 10/11 and Linux): Support "full window
  content" mode, which allows you to extend the content into the window title bar. (PR #801)
• macOS: Support larger window title bar close/minimize/zoom buttons spacing in
  full window content mode and introduced "buttons placeholder". (PR #779)
• Native libraries:
  • System property flatlaf.nativeLibraryPath now supports loading native
    libraries named the same as on Maven central.
  • Published flatlaf-<version>-no-natives.jar to Maven Central. This JAR is
    equal to flatlaf-<version>.jar, except that it does not contain the
    FlatLaf native libraries. The Maven "classifier" to use this JAR is
    no-natives. You need to distribute the FlatLaf native libraries with your application.
    See https://www.formdev.com/flatlaf/native-libraries/ for more details.
  • Improved log messages for loading fails.
• Fonts: Updated Inter to v4.0.
• Table: Select all text in cell editor when starting editing using F2 key. (issue #652)

Fixed bugs

• macOS: Setting window background (of undecorated window) to translucent color
  (alpha < 255) did not show the window translucent. (issue #705)
• JIDE CommandMenuBar: Fixed ClassCastException when JIDE command bar displays
  JideMenu in popup. (PR #794)

Fonts: Inter 4.0

Updated Inter font to v4.0.

Change Log

New features and improvements

• macOS (10.14+): Popups (JPopupMenu, JComboBox, JToolTip, etc.) now use
  native macOS rounded borders. (PR #772; issue #715)
• Native libraries: Added libflatlaf-macos-arm64.dylib and libflatlaf-macos-x86_64.dylib.
  See also https://www.formdev.com/flatlaf/native-libraries/.
• ScrollPane: Support rounded border. (PR #713)
• SplitPane: Support divider hover and pressed background colors. (PR #788)
• TabbedPane: Support vertical tabs. (PR #758, issue #633)
• TabbedPane: Paint rounded tab area background for rounded cards. (issue #717)
• ToolBar: Added styling properties separatorWidth and separatorColor.

Fixed bugs

• Button and ToggleButton: Selected buttons did not use explicitly set
  foreground color. (issue 756)
• FileChooser: Catch NPE in Java 21 when getting icon for .exe files that use
  default Windows exe icon. (see JDK-8320692)
• OptionPane: Fixed styling custom panel background in JOptionPane. (issue #761)
• ScrollPane: Styling ScrollPane border properties did not work if view
  component is a Table.
• Table:
  • Switching theme looses table grid and intercell spacing. (issues #733 and #750)
  • Fixed background of boolean columns when using alternating row colors. (issue #780)
  • Fixed border arc of components in complex table cell editors. (issue #786)
• TableHeader:
  • No longer temporary replace header cell renderer while painting. This avoids
    a StackOverflowError in case that custom renderer does this too. (see
    NetBeans issue #6835) This
    also improves compatibility with custom table header implementations.
  • Header cell renderer background/foreground colors were not restored after
    hover if renderer uses null for background/foreground. (PR #790)
• TabbedPane:
  • Avoid unnecessary repainting whole tabbed pane content area when layouting
    leading/trailing components.
  • Avoid unnecessary repainting of selected tab on temporary changes.
  • Fixed "endless" layouting and repainting when using nested tabbed panes (top
    and bottom tab placement) and RSyntaxTextArea (with enabled line-wrapping)
    as tab content. (see jadx issue #2030)
• Fixed broken rendering after resizing window to minimum size and then
  increasing size again. (issue #767)

Incompatibilities

• Removed support for JetBrains custom decorations, which required
  JetBrains Runtime (JBR) 8 or 11. It did not work for JBR 17. System property
  flatlaf.useJetBrainsCustomDecorations is now ignored. Note: FlatLaf
  window decorations continue to work with JBR.

3.2.5

Fixes a regression in 3.2.1.

Change Log

Fixed bugs

• Popup: Fixed NPE if popup invoker is null on Windows 10.
  (issue #753; regression in 3.2.1 in fix for #626)

3.2.4

Fixes a regression in 3.2.3.

Change Log

Fixed bugs

• Popup: Fixed NPE if popup invoker is null on Linux with Wayland and Java 21.
  (issue #752; regression in 3.2.3)

3.2.3

Update: Do not use this release because it throws a NPE in (unusual) case that the popup invoker is null.

Another bug fix release that fixes a JDK 21+ bug on Linux with Wayland regarding popups that request focus.
If you use complex popups (e.g. with text fields or other components that request focus)
and your application runs on Linux in Java 21 or later, then it is recommended to upgrade to this version.

Change Log

Fixed bugs

• PopupMenu: Popups that request focus were not shown on Linux with Wayland and Java 21. (issue #752)

3.2.2

This is a bug fix release that fixes a JDK 19+ bug regarding HTML text in buttons.
If you use HTML text in buttons and your application runs in Java 19 or later,
then it is recommended to upgrade to this version.

Change Log

Fixed bugs

• Button: Fixed painting icon and text at wrong location when using HTML text,
  left/right vertical alignment and running in Java 19+. (issue #746)
• CheckBox and RadioButton: Fixed cut off right side when border is removed and
  horizontal alignment is set to right. (issue #734)
• TabbedPane: Fixed NPE when using focusable component as tab component and
  switching theme. (issue #745)

3.2.1

This is a bug fix release that fixes a memory leak in class MultiResolutionImageSupport,
which may, in worst case, result in an out-of-memory situation. See change log below for details.

Change Log

Fixed bugs

• Fixed memory leak in MultiResolutionImageSupport.create(int,Dimension[],Function<Dimension,Image>),
  which caches images created by the producer function. Used by FlatSVGIcon.getImage() and
  FlatSVGUtils.createWindowIconImages().
  If you use one of these methods, it is strongly recommended to upgrade to this
  version, because if the returned image is larger and painted very often it may
  result in an out-of-memory situation. (issue #726)
• FileChooser: Fixed occasional NPE in FlatShortcutsPanel on Windows. (issue #718)
• TextField: Fixed placeholder text painting, which did not respect horizontal
  alignment property of JTextField. (issue #721)
• Popop: Fixed drop shadow if popup overlaps a heavyweight component. (Windows 10 only; issue #626)
