what does QBbusyHide() does?

I believe its referring to native dialog box that is showed during the save action. If you take Dan's Demo as an example, which uses this code, after you hit "Save and Close" you'll notice that before the record reloads, it displays the dialog box. During this time, the page is in a frozen state of reloading and during the normal action of a page reload it shows a "Busy" Icon that normally says, "Saving...". Whenever Dan's calls QBbusyHide(), he is hiding that "Saving..." icon and shows the dialog box in its place.


<div id="qbBusyDiv" style="width: auto; min-height: 0px; height: auto;" class="ui-dialog-content ui-widget-content" scrolltop="0" scrollleft="0">
    <span class="BusyIcon"></span>
<span id="qbBusySpan" class="FS-H1">Saving . . .</span>
</div>
