View Full Version : Is it better to close or hide window from performance standpoint

6 Apr 2012, 7:21 AM
On a button click, I create a new window that contains a tree, grid, and tabpanel. From a performance / best practice standpoint, should I do:

A: recreate window on every button click and set window.closeAction: 'true'

B: create window if first time else reset window content and show hidden window. window.closeAction: 'hide'

Some things to consider:
1. Will keeping the window hidden use up a lot of browser memory due to lots of dom objects floating around?
2. Will recreating the window every time be a waste of time?

If the window will be in use a lot, then I would hide it. You can use xtype rendering to load it only when needed,
but once you have it loaded, just keep it around and show it when needed.
