refresh

OK so I have a JList and the content is provided with an array. I know how to add elements to an array but I want to know how to refresh a JList... or is it even possible?

How may I refresh current client view page from the server side? for example, if I want to force refresh for page that is viewing now for all the clients, so they can view the new content. and I want to do this refresh in the time that I want using PHP.

I am dynamically creating dragrids in different rows of an existing datagrid in asp.NET My generated datagrids have a column which is TemplateColumn (a CheckBox Column). In my parent datagrid, I have a template column with checkboxes. when I check or uncheck the value of the check box, the check_change method is called (autopostback is set to true), the dynamically generated datagrids lose the checked checkboxes (the checkboxes are all unchecked again).

I am trying to have a auto refresh feature for the grid which basically, updates the grid with latest data from the server every 'n' seconds. I was able to implement the PollListner whenever the user enables Auto-Refresh. UI ui= TestUI.getCurrent(); Boolean value = isRefreshChkBox.getValue(); PollListener listener = e -> { explorer.reloadUI(); }; if (value) { String refreshRateValue = refreshRateTxtField.getValue(); int refreshRate = Integer.valueOf(refreshRateValue); int millis = (int) TimeUnit.SECONDS.toMillis(refreshRate); absUI.setPollInterval(millis); absUI.addPollListener(listener); }

I have a GWT application and I want to run some code when the user leaves the application to force a logout and remove any data etc. To do this I am using a CloseHandler and registering it using Window.addCloseHandler. I have noticed that when the refresh button is clicked the onClose method is run but I have been unable to differentiate this event from a close where the user has closed the browser. If it is a refresh I do not want to do the logout etc, I only want to do this when the user closes the browser/tab or navigates away from the site. Does anybody know how I can do this? There is no
