GWT - how to precisely set rendered width of TextArea in pixels?

Question

I need to render a TextArea in an exact pixel width for the special purposes of my GUI.

When I set its width to "250px", it comes out as 256px.

Is there a way to override this behavior so I can render it as 250px exactly?

Answer 1

When you use setWidth(), you're effectively setting the element's content width.

To get the offset width use UIObject#getOffsetWidth(). This will return the width including padding and border (but not margins).
