Swing JScrollBar

JScrollBar類實(shí)現(xiàn)滾動(dòng)。

類聲明

以下是javax.swing.JScrollBar類的聲明：

public class JScrollBar
   extends JComponent
      implements Adjustable, Accessible

字段域

以下是javax.swing.ImageIcon類的字段：

protected int blockIncrement
protected BoundedRangeModel model -- 模型表示滾動(dòng)條的最小，最大程度（又名“可視部分”）和當(dāng)前值。
protected int orientation
protected int unitIncrement

類構(gòu)造函數(shù)

S.N.	構(gòu)造函數(shù) & 描述
1	JScrollBar() Creates a vertical scrollbar with the initial values.
2	JScrollBar(int orientation) Creates a scrollbar with the specified orientation and the initial values.
3	JScrollBar(int orientation, int value, int extent, int min, int max) Creates a scrollbar with the specified orientation, value, extent, minimum, and maximum.

類方法

S.N.	方法 & 描述
1	void addAdjustmentListener(AdjustmentListener l) Adds an AdjustmentListener.
2	protected void fireAdjustmentValueChanged(int id, int type, int value) Notify listeners that the scrollbar's model has changed.
3	AccessibleContext getAccessibleContext() Gets the AccessibleContext associated with this JScrollBar.
4	AdjustmentListener[] getAdjustmentListeners() Returns an array of all the AdjustmentListeners added to this JScrollBar with addAdjustmentListener().
5	int getBlockIncrement() For backwards compatibility with java.awt.Scrollbar.
6	int getBlockIncrement(int direction) Returns the amount to change the scrollbar's value by, given a block (usually "page") up/down request.
7	int getMaximum() The maximum value of the scrollbar is maximum - extent.
8	Dimension getMaximumSize() The scrollbar is flexible along it's scrolling axis and rigid along the other axis.
9	int getMinimum() Returns the minimum value supported by the scrollbar (usually zero).
10	Dimension getMinimumSize() The scrollbar is flexible along it's scrolling axis and rigid along the other axis.
11	BoundedRangeModel getModel() Returns data model that handles the scrollbar's four fundamental properties: minimum, maximum, value, extent.
12	int getOrientation() Returns the component's orientation (horizontal or vertical).
13	ScrollBarUI getUI() Returns the delegate that implements the look and feel for this component.
14	String getUIClassID() Returns the name of the LookAndFeel class for this component.
15	int getUnitIncrement() For backwards compatibility with java.awt.Scrollbar.
16	int getUnitIncrement(int direction) Returns the amount to change the scrollbar's value by, given a unit up/down request.
17	int getValue() Returns the scrollbar's value.
18	boolean getValueIsAdjusting() True if the scrollbar knob is being dragged.
19	int getVisibleAmount() Returns the scrollbar's extent, aka its "visibleAmount".
20	protected String paramString() Returns a string representation of this JScrollBar.
21	void removeAdjustmentListener(AdjustmentListener l) Removes an AdjustmentEvent listener.
22	void setBlockIncrement(int blockIncrement) Sets the blockIncrement property.
23	void setEnabled(boolean x) Enables the component so that the knob position can be changed.
24	void setMaximum(int maximum) Sets the model's maximum property.
25	void setMinimum(int minimum) Sets the model's minimum property.
26	void setModel(BoundedRangeModel newModel) Sets the model that handles the scrollbar's four fundamental properties: minimum, maximum, value, extent.
27	void setOrientation(int orientation) Set the scrollbar's orientation to either VERTICAL or HORIZONTAL.
28	void setUI(ScrollBarUI ui) Sets the L&F object that renders this component.
29	void setUnitIncrement(int unitIncrement) Sets the unitIncrement property.
30	void setValue(int value) Sets the scrollbar's value.
31	void setValueIsAdjusting(boolean b) Sets the model's valueIsAdjusting property.
32	void setValues(int newValue, int newExtent, int newMin, int newMax) Sets the four BoundedRangeModel properties after forcing the arguments to obey the usual constraints.
33	void setVisibleAmount(int extent) Set the model's extent property.
34	void updateUI() Overrides JComponent.updateUI.
