that is automatically positioned relative
to a specified anchor point. The popup can be dismissed in the same
manor as all popup dialogs, but additionally allows clients the option
of specifying a command id that can be used to persist the contents of
the dialog.
Clients may subclass this.

protected abstract Control createDialogArea(Composite parent)
PopupDialog
The PopupDialog
implementation of this framework method
creates and returns a new Composite
with standard margins
and spacing.
The returned control's layout data must be an instance of
GridData
. This method must not modify the parent's
layout.
Subclasses must override this method but may call super
as
in the following example:
Composite composite = (Composite) super.createDialogArea(parent); //add controls to composite as necessary return composite;
createDialogArea

parent
- the parent composite to contain the dialog areaprotected Point getInitialLocation(Point initialSize)
getInitialLocation
in class PopupDialog
initialSize
- the initial size of the shell, as returned by

if the dialog's bounds should
never be stored.public int open()
PopupDialog
This method is reimplemented for special configuration of PopupDialogs.
It never blocks on open, immediately returning OK
if the
open is successful, or CANCEL
if it is not. It provides
framework hooks that allow subclasses to set the focus and tab order, and
avoids the use of shell.open()
in cases where the focus
should not be given to the shell initially.
open
in class PopupDialog
Window.open()
public boolean close()
PopupDialog
This method is extended to save the dialog bounds and initialize widget
state so that the widgets can be recreated if the dialog is reopened.
This method may be extended (super.close
must be called).
close
in class PopupDialog
true
if the window is (or was already) closed, and
false
if it is still open
