JFormDesigner/FlatLaf 0.25

on GitHub

Note: Do not use this version from Maven Central. It is broken. Use 0.25.1.

• Hide menu mnemonics by default and show them only when Alt key is
  pressed. (issue #43)
• Menu: Fixed vertical alignment of sub-menus. (issue #42)
• TabbedPane: In scroll-tab-layout, the cropped line is now hidden. (issue #40)
• Tree: UI default value Tree.textBackground now has a valid color and is no
  longer null.
• Tree on macOS: Fixed Left and Right keys to collapse or
  expand nodes.
• ComboBox on macOS: Fixed keyboard navigation and show/hide popup.
• Button and ToggleButton: Support per component minimum height (set client
  property JComponent.minimumHeight to an integer). (issue #44)
• Button and ToggleButton: Do not apply minimum width if button border was
  changed (is no longer an instance of FlatButtonBorder).
• ToggleButton: Renamed toggle button type "underline" to "tab" (value of client
  property JButton.buttonType is now tab).
• ToggleButton: Support per component styling for tab-style toggle buttons with
  client properties JToggleButton.tab.underlineHeight (integer),
  JToggleButton.tab.underlineColor (Color) and
  JToggleButton.tab.selectedBackground (Color). (issue #45)
• ToggleButton: No longer use focus width for tab-style toggle buttons to
  compute component size, which reduces/fixes component size in "Flat IntelliJ"
  and "Flat Darcula" themes.
• TabbedPane: Support per component tab height (set client property
  JTabbedPane.tabHeight to an integer).
• ProgressBar: Support square painting (set client property
  JProgressBar.square to true) and larger height even if no string is
  painted (set client property JProgressBar.largeHeight to true).
