Method Detail
-
getStyle
public static Object getStyle(JComponent c)
Returns the style specified in client propertyFlatClientProperties.STYLE
.
-
getStyleClass
public static Object getStyleClass(JComponent c)
Returns the style class(es) specified in client propertyFlatClientProperties.STYLE_CLASS
.
-
getResolvedStyle
public static Object getResolvedStyle(JComponent c, String type)
-
getStyleForClasses
public static Object getStyleForClasses(Object styleClass, String type)
Returns the styles for the given style class(es) and the given type.The style rules must be defined in UI defaults either as strings (in CSS syntax) or as
Map
<String, Object> (with binary values). The key must be in syntax:[style]type.styleClass
, where the type is optional. E.g. in FlatLaf properties file:
or in Java code:[style]Button.primary = borderColor: #08f; background: #08f; foreground: #fff [style].secondary = borderColor: #0f8; background: #0f8
The rule "Button.primary" can be applied to buttons only. The rule ".secondary" can be applied to any component.UIManager.put( "[style]Button.primary", "borderColor: #08f; background: #08f; foreground: #fff" ); UIManager.put( "[style].secondary", "borderColor: #0f8; background: #0f8" );
To have similar behavior as in CSS, this method first gets the rule without type, then the rule with type and concatenates both rules. E.g. invoking this method with parameters styleClass="foo" and type="Button" does following:
return joinStyles( UIManager.get( "[style].foo" ), UIManager.get( "[style]Button.foo" ) );
- Parameters:
styleClass
- the style class(es) either as string (single class or multiple classes separated by space characters) or asString[]
orList
<String> (multiple classes)type
- the type of the component- Returns:
- the styles
-
joinStyles
public static Object joinStyles(Object style1, Object style2)
Joins two styles. They can be either strings (in CSS syntax) orMap
<String, Object> (with binary values).If both styles are strings, then a joined string is returned. If both styles are maps, then a joined map is returned. If one style is a map and the other style a string, then the string is parsed (using
parse(String)
) to a map and a joined map is returned.- Parameters:
style1
- first style as string or map, ornull
style2
- second style as string or map, ornull
- Returns:
- new joined style
-
concatStyles
public static String concatStyles(String style1, String style2)
Concatenates two styles in CSS syntax.- Parameters:
style1
- first style, ornull
style2
- second style, ornull
- Returns:
- concatenation of the two styles separated by a semicolon
-
parseAndApply
public static Map<String,Object> parseAndApply(Map<String,Object> oldStyleValues, Object style, BiFunction<String,Object,Object> applyProperty) throws FlatStylingSupport.UnknownStyleException, IllegalArgumentException
