Method Details
-
setUrl
Sets the location which is to be displayed in this panel.- Parameters:
url
- locator of resource to display
-
getUrl
Returns the location which is currently displayed in this panel.- Returns:
- locator of displayed resource
-
hasJavaFx
public static boolean hasJavaFx()Indicates whether the JRE has access to JavaFX classes, and hence whether thecreateFxPanel
method ought to work.- Returns:
- true iff createFxPanel ought to work
-
createFxPanel
Attempts to create an HtmlPanel based on JavaFX classes. If it fails (for example because JavaFX classes are not present), null is returned and a report may be made through the loggint system.- Returns:
- JavaFX-based instance, or null
-
createSwingPanel
Creates an HtmlPanel based on Swing classes. This should always work.- Returns:
- Swing-based instance
-
createPanel
Returns a best-efforts HtmlPanel.- Returns:
- instance based on JavaFX if possible, otherwise instance based on Swing
