Method Detail

createHintsComponent

public JComponent createHintsComponent()

Description copied from interface: IntelliHints

Creates the component which contains hints. At this moment, the content should be empty. Following call IntelliHints.updateHints(Object) will update the content.

Returns:

the component which will be used to display the hints.

createList

protected JList createList()

Creates the list to display the hints. By default, we create a JList using the code below.

 return new JList() {
     public int getVisibleRowCount() {
         int size = getModel().getSize();
         return size < super.getVisibleRowCount() ? size : super.getVisibleRowCount();
     }
 

     public Dimension getPreferredScrollableViewportSize() {
         if (getModel().getSize() == 0) {
             return new Dimension(0, 0);
         }
         else {
             return super.getPreferredScrollableViewportSize();
         }
     }
 };
 

Returns:

the list.

protected JList getList()

Gets the list.

Returns:

the list.

setListData

protected void setListData(Object[] objects)

Sets the list data.

Parameters:

objects -

setListData

protected void setListData(Vector<?> objects)

Sets the list data.

Parameters:

getSelectedHint

public Object getSelectedHint()

Description copied from interface: IntelliHints

Gets the selected value. This value will be used to complete the text component.

Returns:

the selected value.

getDelegateComponent

public JComponent getDelegateComponent()

Description copied from class: AbstractIntelliHints

Gets the delegate component in the hint popup.

Specified by:

getDelegateComponent in class AbstractIntelliHints

Returns:

the component that will receive the keystrokes that are delegated to hint popup.

getDelegateKeyStrokes

public KeyStroke[] getDelegateKeyStrokes()

Gets the delegate keystrokes. Since we know the hints popup is a JList, we return eight keystrokes so that they can be delegate to the JList. Those keystrokes are DOWN, UP, PAGE_DOWN, PAGE_UP, HOME and END.

Specified by:

getDelegateKeyStrokes in class AbstractIntelliHints

Returns:

the keystrokes that will be delegated to the JList when hints popup is visible.
