textbox in showcase lower right corner, has a dragger to resize the textbox

[tong123123]

in the showcase
http://gwt.google.com/samples/Showcase/Showcase.html#!CwBasicText
the textbox lower right corner has a dragger to resize the textbox, how to do it?

 I try

TextArea ta = new TextArea();
 ta.setCharacterWidth(80);
 ta.setVisibleLines(5);

but the textbox generated has no such a resize dragger.

Its a CSS3 property named "resize", see: http://www.w3schools.com/cssref/css3_pr_resize.asp

Currently only supported on the browsers listed at: http://caniuse.com/#search=resize

It might because of setCharacterWidth(), that's the only difference from the showcase.

Anyway, the dragger is "native", added and handled by your browser, so it also depends which browser you use.
