Examples with ImageInfo com.codename1.ui.plaf.StyleParser.ImageInfo used on opensource projects

Example 1 with ImageInfo

use of com.codename1.ui.plaf.StyleParser.ImageInfo in project CodenameOne by codenameone.

the class UIManager method parseStyle.

/**
 * Creates a style by providing style strings in a specific format. This method allows for the use of inline styles
 * to override the styles in {@link com.codename1.ui.Component}
 * @param theme Theme used to retrieve images referenced in the style strings.
 * @param id The style ID (UIID) to use to cache the style inside the theme.
 * @param prefix Prefix to use for styles.  Corresponds to the {@literal prefix} argument in {@link #getComponentStyleImpl(java.lang.String, boolean, java.lang.String)
 * @param baseStyle The style class from which this new style should derive.
 * @param selected True if this is for a selected style.
 * @param styleString Array of style strings to be parsed.  The format is {@literal key1:value1; key2:value2; etc...}.  While this looks similar to CSS, it is important to note that it is NOT
 * CSS.  The keys and values correspond to the properties of {@link com.codename1.ui.plaf.Style} and their associated values.
 * @return A style object representing the styles that were provided in the styleString.
 *
 * <h3>Example Usage</h3>
 *
 * {@code
 * Style s = parseStyle(theme, "Button[MyCustomButton]", "", "Button", false,
 *     "fgColor:ff0000; font:18mm; border: 1px solid ff0000; bgType:none; padding: 3mm; margin: 1mm");
 *
 * // Create a 9-piece image border on the fly:
 * Style s = parseStyle(theme, "Button[MyCustomButton]", "", "Button", false,
 *      "border:splicedImage /notes.png 0.3 0.4 0.3 0.4");
 *      // This splices the image found at /notes.png into 9 pieces.  Splice insets are specified by the 4 floating point values
 *      // at the end of the border directive:  [top] [right] [bottom] [left].
 * }
