Method Details

updateRendererCSSFontBaseSize

public static void updateRendererCSSFontBaseSize(JComponent c)

Adds CSS rule BASE_SIZE to the style sheet of the HTML view, which re-calculates font sizes based on current component font size. This is necessary for "absolute-size" keywords (e.g. "x-large") for "font-size" attributes in default style sheet (see javax/swing/text/html/default.css). See also CSS font-size.

This method should be invoked after BasicHTML.updateRenderer(JComponent, String).

indexOfTag

private static int indexOfTag(String html,
 String tag,
 boolean endIndex)

Returns start or end index of a HTML tag. Checks only for leading 'invalid input: '<'' character and (case-ignore) tag name.

usesAbsoluteSizeKeywordForFontSize

private static boolean usesAbsoluteSizeKeywordForFontSize(View view)

Checks whether view uses "absolute-size" keywords (e.g. "x-large") for font-size (see javax/swing/text/html/default.css).
