I have a PopupPanel with a Label inside. I'm trying to center the popup
horizontally, so I'm calling setPopupPositionAndShow. In the callback,
however, the offsetWidth and offsetHeight arguments don't take into account
any margins or padding, whether I set them on the popup or the label: the
values are always for the text of the label only. Besides the arguments to
the callback, I get the same (incorrect) results from calling
getOffsetWidth/Height on the label or the popup directly.
PopupPanel#center() also does not work correctly. Tested on both Chrome and
Firefox.
Here's the code I'm using to set the position:
messageLabel.setText(message);
popup.setPopupPositionAndShow(new PositionCallback() {
@Override
public void setPosition(int offsetWidth, int offsetHeight) {
popup.setPopupPosition((Window.getClientWidth() - offsetWidth) / 2,
popupTop);
}
});
The PopupPanel is in a UiBinder; not sure if that's relevant. Am I doing
something wrong, or should I file a bug?
