how to show horizontal scrollbar in scrollpanel automatically?

[tong123123]

I have a scrollpanel enclosing a tree. when the tree node expands, the scrollpanel can show the vertical scrollbar automatically. but it cannot show the horizontal scrollbar automatically, instead, only eclipse (...) is shown for overflow item.
so how to show the horizontal scrollbar automatically when the tree expand inside a scrollpanel?

This is not a standard behavior. You must have a CSS style applied to your scroll panel or its content which resets overflow property. It should be overflow:auto.

No, the scrollpanel overflow property is already auto, but the horizontal scrollbar cannot be shown in ie8 or FF13
I set the css using

scrollPanel.getElement().setAttribute("style", "width:210px;height:247px;border:1px solid #B5BBC8; overflow:auto;");

In FireFox, I use firebug and see
element.style{
   border: 1px solid #B5BBC8;
   height: 247px;
   overflow: auto;
   width: 210px;
}

Remove white-space: nowrap; and text-overflow: ellipsis rules that are applied to your scroll panel.

 

I recommend asking such questions on SO.
