Eclipse开发经典教程：展现组件

public class SliderExample {
Display dispaly;
Shell shell;
SliderExample() {
dispaly = new Display();
shell = new Shell(dispaly);
shell.setSize(300, 250);
shell.setText("A Slider Example");
//添加Slider对象 
final Slider slide = new Slider(shell, SWT.V_SCROLL);
//设置Slider的位置和大小 
slide.setBounds(170, 25, 25, 20);
//设置Slider的最小值 
slide.setMinimum(0);
//设置Slider的最大值 
slide.setMaximum(100);
//设置Slider单击左右箭头的增加或递减值 
slide.setIncrement(1);
final Text t = new Text(shell, SWT.BORDER);
t.setBounds(115, 25, 55, 20);
t.setText("0");
t.setFocus();
//添加Slider的事件监听器 
slide.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
t.setText(new Integer(slide.getSelection()).toString());
}
});
shell.open();
while (!shell.isDisposed()) {
if (!dispaly.readAndDispatch())
dispaly.sleep();
}
dispaly.dispose();
}
public static void main(String[] args) {
new SliderExample();
}
}
