Examples of org.eclipse.ui.forms.widgets.ImageHyperlink

org.eclipse.ui.forms.widgets.ImageHyperlink
This class extends hyperlink widget by adding the capability to render an image relative to the text. If no text has been set, only image will be shown. Images for hover and active states can be set in addition to the normal state image.
When image is taller than the text, additional style can be provided to control vertical alignment (supported values are SWT.TOP, SWT.BOTTOM and SWT.CENTER).
The class does not need to be sublassed but it is allowed to do so if some aspect of the image hyperlink needs to be modified.

Styles:

SWT.WRAP, SWT.BOTTOM, SWT.TOP, SWT.MIDDLE, SWT.LEFT, SWT.RIGHT
