public abstract class BaseCombo
extends org.eclipse.swt.widgets.Canvas
The AbstractCombo is an abstract class which provides the basic functionality for a button with a DROP_DOWN, or "popup", shell component. When the user selects the button the shell is set visible and the SWT Components which have been placed on the "content" Composite will be shown.

    • addKeyListener

      public void addKeyListener​(org.eclipse.swt.events.KeyListener listener)
      Adds the listener to the collection of listeners who will be notified when keys are pressed and released on the system keyboard, by sending it one of the messages defined in the KeyListener interface.

      When a key listener is added to a control, the control will take part in widget traversal. By default, all traversal keys (such as the tab key and so on) are delivered to the control. In order for a control to take part in traversal, it should listen for traversal events. Otherwise, the user can traverse into a control but not out. Note that native controls such as table and tree implement key traversal in the operating system. It is not necessary to add traversal listeners for these controls, unless you want to override the default traversal.

      Overrides:
      addKeyListener in class org.eclipse.swt.widgets.Control
      Parameters:
      listener - the listener which should be notified
      Throws:

    • 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 the ModifyListener interface.
      Note that this is NOT the correct way to listen for changes in the underlying model for the combo. This should be provided by some other mechanism, such as a SelectionListener.
      Parameters:
      listener - the listener which should be notified
      Throws:
      java.lang.IllegalArgumentException -
      • ERROR_NULL_ARGUMENT - if the listener is null

      Button visibility will be handled automatically through focus events, popup events, as well as programmatically
      Style BUTTON_MANUAL:
      Button visibility will only be handled programmatically
