Swing JSpinner

JSpinner類是一個(gè)組件，它可以讓用戶選擇一個(gè)數(shù)字或者一個(gè)對(duì)象值從一個(gè)有序的序列使用一個(gè)輸入字段中。

類聲明

以下是聲明 javax.swing.JSpinner類：

public class JSpinner
   extends JComponent
      implements Accessible

類構(gòu)造函數(shù)

S.N. 構(gòu)造函數(shù) & 描述
1 JSpinner() 
Constructs a spinner with an Integer SpinnerNumberModel with initial value 0 and no minimum or maximum limits.
2 JSpinner(SpinnerModel model) 
Constructs a complete spinner with pair of next/previous buttons and an editor for the SpinnerModel.

類方法

S.N. 方法 & 描述
1 void addChangeListener(ChangeListener listener) 
Adds a listener to the list that is notified each time a change to the model occurs.
2 void commitEdit() 
Commits the currently edited value to the SpinnerModel.
3 protected JComponent createEditor(SpinnerModel model) 
This method is called by the constructors to create the JComponent that displays the current value of the sequence.
4 protected void fireStateChanged() 
Sends a ChangeEvent, whose source is this JSpinner, to each ChangeListener.
5 AccessibleContext getAccessibleContext() 
Gets the AccessibleContext for the JSpinner
6 ChangeListener[] getChangeListeners() 
Returns an array of all the ChangeListeners added to this JSpinner with addChangeListener().
7 JComponent getEditor() 
Returns the component that displays and potentially changes the model's value.
8 SpinnerModel getModel() 
Returns the SpinnerModel that defines this spinners sequence of values.
9 Object getNextValue() 
Returns the object in the sequence that comes after the object returned by getValue().
10 Object getPreviousValue() 
Returns the object in the sequence that comes before the object returned by getValue().
11 SpinnerUI getUI() 
Returns the look and feel (L&F) object that renders this component.
12 String getUIClassID() 
Returns the suffix used to construct the name of the look and feel (L&F) class used to render this component.
13 Object getValue() 
Returns the current value of the model, typically this value is displayed by the editor.
14 void removeChangeListener(ChangeListener listener) 
Removes a ChangeListener from this spinner.
15 void setEditor(JComponent editor) 
Changes the JComponent that displays the current value of the SpinnerModel.
16 void setModel(SpinnerModel model) 
Changes the model that represents the value of this spinner.
17 void setUI(SpinnerUI ui) 
Sets the look and feel (L&F) object that renders this component.
18 void setValue(Object value) 
Changes current value of the model, typically this value is displayed by the editor.
19 void updateUI()

      });    
      headerLabel = new JLabel("", JLabel.CENTER);        
      statusLabel = new JLabel("",JLabel.CENTER);    

      statusLabel.setSize(350,100);

      controlPanel = new JPanel();
      controlPanel.setLayout(new FlowLayout());
