Question

I have a GWT app that have a HorizontalPanel that span across the width of the page, that serves as the “top bar” of the app. However I want to make it “sticky” that is when the page content grows, and when scrollbar appears, when scrolled I want the said HorizontalPanel to stick on top. Is it possible to do with GWT and/or with the help of GQuery?

Answer 1

By using CSS:

Add/set a css class to your HorizontalPanel

myHorizontalPanel.setStyleName("onTop");

In you css file:

.onTop{
  position: fixed;
  top: 0px;
  left: 0px;
  /* adapt width and heigth to fit your needs */
  width:100%;
  height:40px;
}

That should do the trick
