Class protocol:

cleanup
o  lowSpaceCleanup
(comment from inherited method)
ignored here - redefined in some classes to
cleanup in low-memory situations

instance creation
o  for: anEditView

queries
o  isAbstract
(comment from inherited method)
Return if this class is an abstract class.
True is returned for Object here; false for subclasses.
Abstract subclasses must redefine this again.


Instance protocol:

accessing
o  editView: anEditTextView

events
o  buttonPress: button x: x y: y

o  editViewLostFocus
this is a hack for Windows:
on windows, an activate:false event is first sent to my textView,
then an activate is sent to the completion popup.
this is done BEFORE the buttonPress event is delivered.
therefore, allow for the activate of the completionMenu and its button event to be processed.
before forcing it to be closed...

o  handleKeyPress: key x: x y: y
return true, if I have eaten this keypress

o  postKeyPress: key
only update, if already open

o  startTimeoutForEditViewLostFocus
see comment in #editViewLostFocus

private
o  computeAndShowCompletions
compute completions, then push an event to show them.
Notice: this is interrupted and terminated if the user presses another key
within delayTime

o  computeCompletions
compute the completions.
Don't know how to do this here.

o  release
(comment from inherited method)
remove all references to objects that may refer to self.
Subclasses may redefine this method but should do a 'super release'.

o  startCompletionProcess
start the code completion process in the background

o  stopCompletionProcess
kill any background completion process

o  updateCompletionList
called for keypress events

private-API
o  adjustPositionAndSizeOfCompletionView: topViewOfCompletionView
oops - no cursor shown???

o  adjustSizeOfCompletionView: topViewOfCompletionView

o  closeCompletionView
completionView := nil.

o  openCompletionView
Opens the completion view with an initial list. Called as soon as
completion is initiated but completion options are not yet computed.

o  openCompletionView: list
Makes sure the completion view is opened and with given `list`.
