Change Log

New features and improvements

• Windows 11: Popups (JPopupMenu, JComboBox, JToolTip, etc.) now use
  native Windows 11 rounded borders and drop shadows. (PR #643)
• Fonts:
  • Added Roboto Mono (https://fonts.google.com/specimen/Roboto+Mono). (PR #639, issue #638)
  • Updated JetBrains Mono to v2.304.
• Theme Editor: Support macOS light and dark themes.
• TabbedPane: Support hover and focused tab foreground colors. (issue #627)
• TabbedPane: tabbedPane.getBackgroundAt(tabIndex) now has higher priority
  than TabbedPane.focusColor and TabbedPane.selectedBackground. If
  tabbedPane.setBackgroundAt(tabIndex) is used to set a color for a single
  tab, then this color is now used even if the tab is focused or selected.
• TableHeader: Support column hover and pressed background and foreground
  colors. (issue #636)
• Native libraries: Made it easier to distribute FlatLaf native libraries
  (Windows .dll and Linux .so) to avoid problems on operating systems with
  enabled execution restrictions.
  See https://www.formdev.com/flatlaf/native-libraries/ for more details. (issue #624)
  • Published native libraries to Maven Central for easy using them as
    dependencies in Gradle and Maven.
  • If available, native libraries are now loaded from same location as
    flatlaf.jar, otherwise they are extract from flatlaf.jar to temporary
    folder and loaded from there.
  • Windows DLLs are now digitally signed with FormDev Software GmbH certificate.

Fixed bugs

• FlatLaf window decorations:
  • Fixed inconsistent size of glass pane depending on whether FlatLaf window
    decorations are used (e.g. Windows 10/11) or not (e.g. macOS). Now the glass
    pane no longer overlaps the FlatLaf window title bar. (issue #630)
  • Linux: Fixed broken window resizing on multi-screen setups. (issue #632)
  • Linux: Fixed behavior of maximize/restore button when tiling window to left
    or right half of screen. (issue #647)
• IntelliJ Themes:
  • Fixed default button hover background in "Solarized Light" theme. (issue #628)
  • Avoid that accent color affect some colors in some IntelliJ themes. (issue #625)
  • Updated "Hiberbee Dark" and "Material Theme UI Lite" themes.
• Styling: Fixed resolving of UI variables in styles that use other variables.
• MenuItem: Fixed horizontal alignment of icons. (issue #631)
• Table: Fixed potential performance issue with paint cell focus indicator
  border. (issue #654)
• Tree: Fixed missing custom closed/opened/leaf icons of a custom
  DefaultTreeCellRenderer. (issue #653; regression since implementing PR #609
  in FlatLaf 3.0)
• Tree: Fixed truncated node text and too small painted non-wide node background
  if custom cell renderer sets icon, but not disabled icon, and tree is
  disabled. (issue #640)
• Fixed HiDPIUtils.paintAtScale1x(), which painted at wrong location if
  graphics is rotated, is scaled and x or y parameters are not zero. (issue #646)
