Is there a way to block the user from triggering new events while the processing icon is spinning? (ie. Rather than queueing up all events and running them one by one?)
Basically I'm trying to prevent impatient users from clicking everywhere while lists are populating, children frames are loading, etc.
Thanks,
Gordon
Hi,
Blocking all events when something happens is not easy, I think a hignlighted window is an alternative to match your request, there is an example to show the idea
<window title="new page title" border="normal">
<label id="statusLabel" value="before loading"/>
<button label="load data">
<attribute name="onClick">
WarningWin.doHighlighted();
statusLabel.setValue("loading");
</attribute>
</button>
</window>
<window id="WarningWin" title="warning" border="normal" visible="false">
Please wait...
<button label="cancel" onClick="WarningWin.setVisible(false)"/>
</window>
When you click the button load data, a window will be highlighted to make sure users can't access all components before clicking the button cancel. You can revise your code with the idea.
Hideokidd,
Thanks for the tip, I'll play around with that. Alternatively, do you know where I can edit the look and feel of that processing spinner animation? Preliminary user feedback from my app suggests that some people miss the spinner because it is in the top left of the page. I'd like to move it to the center of the screen (like the 'loading...' spinner that is fired up when the ZK Demo is loaded up) so that it is more prominent.

Hello,
This configuration in zk.xml might solve both of your problems.
It will center the processing message, also act as a modal, making impossible the interaction with the background components.
Note that this might get your app a little slower
<!-- Optional -->
<device-config>
<!-- Configure the progress message to show in the center -->
<embed><![CDATA[
<script type="text/javascript">
AU_progressbar = function (id, msg)
{
Boot_progressbox(id, msg, 0, 0, true, true);
};
</script>
]]></embed>
</device-config>

Magruga, I've just copied the code you posted on my zk.xml, here's part of it:
<?xml version="1.0" encoding="UTF-8"?>
<!-- zk.xml
Purpose:
Description:
History:
Created by ZK Studio
-->
<zk>
<!-- Turn on the following if you want to keep session after Web server restarts
<system-config>
<ui-factory-class>org.zkoss.zk.ui.http.SerializableUiFactory</ui-factory-class>
</system-config>
-->
<!-- Turn on the following if used with WebLogic 9.1
<system-config>
<cache-provider-class>org.zkoss.zk.ui.sys.GlobalDesktopCacheProvider</cache-provider-class>

<!-- Turn on to test FailoverManager with an useless failover manager

<!-- Optional -->
<!-- You can define any number of richlets as follows.
Note: To use richlet, you have to map zkLoader to /xx/* in web.xml,
where xx could be any name. And, the final URL will be /xx/richlet-url.

<device-config>
<!-- Configure the progress message to show in the center -->
<embed><![CDATA[
<script type="text/javascript">
AU_progressbar = function (id, msg)
{
Boot_progressbox(id, msg, 0, 0, true, true);
};
</script>
]]></embed>
</device-config>
But the "processing" dialog is still showing at the top-left corner of the screen and no overlapping is being made....all the other components are fully accessible while the dialog is showing.
Can you help me with this please?
thanks in advance,
judacoor
Hello judacoor,
Everything appears to be right, it might be a typo error.
Did you tried to remove all the info in zk.xml and let only the device-config tag to see if works?
Also, what is your zk version?
Regards,
Madruga
Madruga,
I've just finished trying only with your snippet in my zk.xml but it didn't work anyways. It had only the device-config tag and still did not work...
BTW, I'm currently using ZK 3.5.2
Any ideas why this is happening?
Thanks,
judacoor
That's very strange. It should be straight forward
Can you confirm that your zk.xml is loaded?
In your web server log should be something like "INFO: Parsing file:path_to_file/web-app/WEB-INF/zk.xml"

I think the zk.xml missed the a line "<device-type>ajax</device-type>" and it should be:
<!-- Optional -->
<device-config>
<!-- Configure the progress message to show in the center -->
<device-type>ajax</device-type>
<embed><![CDATA[
<script type="text/javascript">
AU_progressbar = function (id, msg)
{
Boot_progressbox(id, msg, 0, 0, true, true);
};
</script>
]]></embed>
</device-config>
