Calculator
public Calculator(org.eclipse.swt.widgets.Composite parent, int style)Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.The style value is either one of the style constants defined in class
SWT
which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using theint
"|" operator) two or more of thoseSWT
style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.- Parameters:
parent
- a composite control which will be the parent of the new instance (cannot be null)style
- the style of control to construct- Throws:
java.lang.IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the parent is null
org.eclipse.swt.SWTException
-- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent

addModifyListener
public void addModifyListener(org.eclipse.swt.events.ModifyListener listener)Adds the listener to the collection of listeners who will be notified when the receiver's text is modified, by sending it one of the messages defined in theModifyListener
interface.- Parameters:
listener
- the listener which should be notified- Throws:
java.lang.IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the listener is null
org.eclipse.swt.SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

getValue
public java.lang.String getValue()- Returns:
- the value
-
removeModifyListener
public void removeModifyListener(org.eclipse.swt.events.ModifyListener listener)Removes the listener from the collection of listeners who will be notified when the receiver's text is modified.- Parameters:
listener
- the listener which should no longer be notified- Throws:
java.lang.IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the listener is null
org.eclipse.swt.SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
