如何更改内容面板gxt的标题

Question

我正在努力通过改变它的颜色使内容面板的标题看起来像闪烁。但我正在尝试的代码不起作用，这里是代码：

public class Reminder extends ContentPanel{
Timer time = new Timer{
public void run(){
rpc.getReminders(new AsyncCallBack<ArrayList<ModelData>>(){
public voidonFailure(Throwable caught)
{ }
public void onSuccess(ArrayList<ModelData> result){
//the next line does not affect any result
getHeader().setStyleAttribute("backgroundColor","red");
//even tried throught css, but both of them gave no result
getHeader().addStyleName("myredpanel");
//But this method is working, but its also overwriting the parents css styles, but i only need to change backgroun color
getHeader().setStyleName("myredpanel");
})

搜索论坛，但这些例子不适用于我的论坛？还有什么建议？

Answer 1

致电setStyleAttribute时，请勿使用驼峰案例名称。

getHeader().setStyleAttribute("backgroundColor","red"); // WRONG

getHeader().setStyleAttribute("background-color","red"); // CORRECT

Answer 2

如果您使用的是gxt 3.0.X，则应更改ContentPanelAppereance，直接样式设置可能没有帮助。如果你愿意，我可以发一个例子。
