getThemeURIs

public java.util.Collection<java.lang.Object> getThemeURIs(Execution exec,
                                                           java.util.List<java.lang.Object> uris)

Description copied from interface: ThemeProvider

Returns a list of the theme's URIs of the specified execution, or null if no theme shall be generated. Each item could be an instance of either String or StyleSheet. If you want to specify the media attribute, use StyleSheet.

It is called when a desktop is about to be rendered. It is called only once for each desktop.

Notice that StyleSheet is allowed since 5.0.3.

Specified by:

getThemeURIs in interface ThemeProvider

Overrides:

getThemeURIs in class StandardThemeProvider

Parameters:

exec - the current execution (never null), where you can retrieve the desktop, request and response. Note: if your Web application supports multiple devices, you have to check Desktop.getDevice().

uris - the default set of theme's URIs, i.e., the themes defined in language definitions (lang.xml and lang-addon.xml) and the configuration (the theme-uri elements in web.xml). Each URI is an instance of of either String or StyleSheet. Notice that, unless it is customized by application specific lang-addon, all URIs are, by default, String instances.

Returns:

the collection of the theme's URIs that the current desktop shall use. Each URI is an instance of of either String or StyleSheet.

beforeWidgetCSS

public java.lang.String beforeWidgetCSS(Execution exec,
                                        java.lang.String uri)

Description copied from interface: ThemeProvider

Called when a WCS (Widget CSS descriptor) file is about to load the CSS file associated with a widget. This method then returns the real URI of the WCS file to load. If no need to change, just return the uri parameter.

This method is usually overridden to load the CSS files from a different directory. For example,

String beforeWidgetCSS(Execution exec, String uri) {
  return uri.startsWith("~./") ? "~./foo/" + uri.substring(3): uri;
}

Specified by:

beforeWidgetCSS in interface ThemeProvider

Overrides:

beforeWidgetCSS in class StandardThemeProvider

Parameters:

exec - the current execution (never null), where you can retrieve the request ad response. However, unlike ThemeProvider.getThemeURIs(org.zkoss.zk.ui.Execution, java.util.List), the desktop might not be available when this method is called.

uri - the URI of the CSS file associated with a widget, e.g., ~./js/zul/wgt/css/a.css.dsp

Returns:

the real URI of the CSS file to load If null is returned, the CSS file is ignored.
