Eclipse开发经典教程：展现组件

public class CoolBarExample extends ApplicationWindow {
public CoolBarExample() {
super(null);
}
protected Control createContents(Composite parent) {
getShell().setText("CoolBar Test");
String asCoolItemSection[] = { "File", "Formatting", "Search" };
//添加CoolBar 
CoolBar composite = new CoolBar(parent, SWT.NONE);
for (int idxCoolItem = 0; idxCoolItem < 3; ++idxCoolItem) {
CoolItem item = new CoolItem(composite, SWT.NONE);
//添加子组件 
ToolBar tb = new ToolBar(composite, SWT.FLAT);
for (int idxItem = 0; idxItem < 3; ++idxItem) {
ToolItem ti = new ToolItem(tb, SWT.NONE);
ti
.setText(asCoolItemSection[idxCoolItem] + " Item #"
+ idxItem);
}
Point p = tb.computeSize(SWT.DEFAULT, SWT.DEFAULT);
tb.setSize(p);
Point p2 = item.computeSize(p.x, p.y);
//设置为一个CoolItem的控制类 
item.setControl(tb);
item.setSize(p2);
}
return composite;
}
public static void main(String[] args) {
CoolBarExample app = new CoolBarExample();
app.setBlockOnOpen(true);
app.open();
Display.getCurrent().dispose();
}
}
