帮帮忙,看看代码问题啊

Question

int bardrateReady;{
combo2 = new Combo(group1, SWT.READ_ONLY);
combo2.setBounds(91, 58, 145, 20);
combo2.setItems(new java.lang.String[] {"9600","4800","2400","1200","600","300"});
combo2.select(baudrateReady);
combo2.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent evt) {
//System.out.println("combo2.widgetSelected, event="+evt);
//baudrateReady = Integer.parseInt(combo2.getText());
baudrateReady = combo2.getSelectionIndex();
System.out.println(baudrateReady);
}
});
}
这是一个combo的代码,我想在一触发选择事件的时候就提取所选择的项的索引,可是为什么每次选择好,打印出来都是0啊,谁懂这个请帮帮我啊
