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
IInformationControl.isFocusControl() is implemented like this (
fShell is the
return fShell.getDisplay().getActiveShell() == fShellLikewise,
IInformationControl.addFocusListener(org.eclipse.swt.events.FocusListener)should install listeners for
SWT.Deactivateon the shell and forward events to the focus listeners. Clients are encouraged to subclass
AbstractInformationControl, which does this for free.

Method SummaryModifier and TypeMethodDescription
(int widthInChars, int heightInChars)Computes the width- and height constraints of the information control in pixels, based on the given width and height in characters.
booleanTests whether the given control is this information control or a child of this information control.Returns the rich information control creator for this information control.
(Control control)Tests whether the given control is this information control or a child of this information control.
control- the control to test
trueiff the given control is this information control or a child of this information control
trueiff the information control is currently visible
(int widthInChars, int heightInChars)Computes the width- and height constraints of the information control in pixels, based on the given width and height in characters. Implementors should use the main font of the information control to do the characters-to-pixels conversion. This is typically the
widthInChars- the width constraint in number of characters
heightInChars- the height constraint in number of characters

getInformationPresenterControlCreatorIInformationControlCreator getInformationPresenterControlCreator()Returns the rich information control creator for this information control.
The returned information control creator is used to create an enriched version of this information control, e.g. when the mouse is moved into this control and it needs to be
enrichedor when it needs to be made sticky for other reasons.
The returned information control creator must create information controls that implement
IInformationControlExtension2, and whose
IInformationControlExtension2.setInput(Object)accepts all inputs that are also supported by this information control.
Note that automatic enriching of this information control works only if it also implements
This method may be called frequently, so implementors should ensure it returns quickly, e.g. by caching the returned creator.
