- arrow keys move focus within toolbar (provided by `BasicToolBarUI`)
- tab-key moves focus out of toolbar
- if moving focus into the toolbar, focus recently focused toolbar button
(issue #346)
- renamed `MenuItemCheckBox.icon.checkmarkColor` to `CheckBoxMenuItem.icon.checkmarkColor`
- renamed `MenuItemCheckBox.icon.disabledCheckmarkColor` to `CheckBoxMenuItem.icon.disabledCheckmarkColor`
(Note: this are incompatible changes!)
- renamed `@disabledText` to `@disabledForeground`
- renamed `@textComponentBackground` to `@componentBackground`
- renamed `@textComponentMargin` to `@componentMargin`
- added `@disabledBackground`
(Note: this are incompatible changes!)
- reworked core themes
- reduced explicit colors by using color functions
- made it easier to create new themes
- avoid using colors from one component type for another component type
(except when useful; e.g. `Separator.foreground` is also used for other separators)
- HelpButton: use colors from Button (instead of from CheckBox.icon)
- ToolBar: improved "docking" and "floating" colors
- check for duplicate keys in StyleableInfos to find "overlapping" fields/properties (e.g. `borderColor` in `FlatBorder` and in `FlatComboBoxUI`)
- Button and ToggleButton: fixed styling `toolbar.spacingInsets`
- use new StringUtils.split(..., boolean trim, boolean excludeEmpty) where possible
- added substringTrimmed() and isTrimmedEmpty() to avoid temporary string allocation
Theme Editor:
- do not set client property `JComponent.focusOwner` on internal components of combobox and spinner
- repaint preview on window activation (necessary because if something changed in editor and switching to another app, the editor is saved and the preview is updated while the editor window is not-active, which hides all focus indicators)
- added `Component.accentColor`
- dark themes: changed threshold for contrast() from 39% down to 25% for better readability of text
- Demo: added "Default" accent color and changed "Blue" to lighter color
(issue #233)
- introduced @accentBaseColor variable that is now used as base for accent colors in Light/Dark/IntelliJ/Darcula themes, which use variations of the accent color
- @accentColor is now `null` by default, but if set to a color, then it is used unmodified for all accents
(issue #233)
