Autohiding of GWT popup panel

Question

How to hide GWT DecoratedPopupPanel after some time? I can make it with Timer class, but may be exist some more elegant way?

Answer 1

Maybe GWT Scheduler is more elegant way for your task than timer.

See scheduleFixedDelay

Answer 2

Absolutely not. You must create a Timer object to handle it

Answer 3

if you want to hide it when user clicks outside it you can specify autohide property

DecoratedPopupPanel

public DecoratedPopupPanel(boolean autoHide,
                           boolean modal)

    Creates an empty decorated popup panel, specifying its "auto-hide" and "modal" properties.

    Parameters:
        autoHide - true if the popup should be automatically hidden when the user clicks outside of it
        modal - true if keyboard or mouse events that do not target the PopupPanel or its children should be ignored

refer javaDoc

other option is Timer class as you have discovered.
