Examples of org.eclipse.jface.text.IInformationControlExtension5

org.eclipse.jface.text.IInformationControlExtension5
Extension interface for {@link org.eclipse.jface.text.IInformationControl}. Adds API
- to test the visibility of the control,
- to test whether another control is a child of the information control,
- to compute size constraints based on the information control's main font and
- to return a control creator for an enriched version of this information control.
Important: Enriching this information control only works properly if {@link IInformationControl#isFocusControl()} is implemented like this (fShellis the control's shell):
```
 return fShell.getDisplay().getActiveShell() == fShell 
```
Likewise, {@link IInformationControl#addFocusListener(org.eclipse.swt.events.FocusListener)}should install listeners for {@link SWT#Activate} and {@link SWT#Deactivate}on the shell and forward events to the focus listeners. Clients are encouraged to subclass {@link AbstractInformationControl}, which does this for free.
