Is Gwt PopupPanel method setPopupPosition overwritten when adding it to another Panel?

Question

I'd like to set the position of my PopupPanel relative to the Panel I'm adding it to. However, the position I set with

popupPanel.setPopupPosition(750,230);

is ignored.

Is the method position overwritten when adding it to a panel?

You don't “add a PopupPanel to a panel”. If you do that, then you're treating it like it's a SimplePanel, and it behaves almost like a SimplePanel; so yes setPopupPosition won't work, at least without some additional CSS applied.

If you want to show a PopupPanel relative to another element, use setPopupPositionAndShow and compute the position relative to the other element's absolute position.
