Relative to https://javafx-jira.kenai.com/browse/RT-38640, I propose to
add the following method to Region:
/**
* An implementation may specify its own user-agent styles for this
Region, and its children,
* by overriding this method. These styles are used in addition to
whatever user-agent stylesheets
* are in use. This provides a mechanism for third parties to
introduce styles for custom controls.
* @return A string URL
*/
public string getUAStylesheet()
Note: an alternative is to make Control method getUserAgentStylesheet
public and move it to Region. But I'm not sure about binary
compatibility and, in the interest of time, I'm putting this API out
there. The reasons for putting this API on Region is eloquently stated
by Jonathan in the JIRA issue.
