I would like to change the color that is visible behind the "processing" dialog (Clients.showBusy(String label)) when I am redirecting from one zul page to another.

My zul's all have a black background, but when you do redirect to another zul from server side processing in Java (subclasses of GenericForwardComposer) using Executions.sendRedirect, until the other page loads, I get a white/greyish background behind my processing dialog I put up. I want to make the background black while I am between pages.

My windows are all defined to have a black background via CSS, and I have the body tag overloaded in my style sheets to have a black background.

I am running both on a desktop browser and in an Ipad UIWebView. I tried on the Ipad to make the UIWebView background solid black to see if that would do it, but I end up with a grey background between pages so it's something in the HTML that is making it that color since I know my background behind the html (the UIWebView) is black.

Any help appreciated! Thanks! Andy

Hi, you can try modify the CSS style

.z-modal-mask {
    background: black;
    opacity: 1.0;

I tried that, no luck, I also have tried : .z-window { background : #000000 !important; } without success.

Let me update - that did have some effect, I get "less" white before and after the processing, but behind the processing is still white/grey.

I even tried specifying a background image for the body that's all black, didn't work. body { background: url("./images/system/defaultbackground.png") no-repeat scroll 0 0 rgba(0, 0, 0, 0); padding: 0 !important; }

There is another style "opacity:0.6", just modify it to "opacity: 1.0". Update the answer

We finally figured out what was going on (thanks to Vincent!).

The settings he provides above for your style sheet are correct and will work - HOWEVER - if you are using stylesheets like I am and importing them into your pages via the <style> tag it won't work.I t's very important that you use the <?style src="yourstylesheet.css" ?> tag instead at the top of your zul file to include the sheet that has the css code

.z-modal-mask {
    background: black;
    opacity: 1.0;

I was including the style sheet using <style src="mystyle.css"/> inside my window tags. This doesn't set the style until the window has already started processing, which is too late for the changes I was trying to make.

I ended up going with the following CSS to eliminate the processing dialog and it's window behind it (actually a div)

    padding:0 0 0 0 !important;   
    background : #000000;
.z-temp, .z-modal-mask
    display : none !important;
    visibility : hidden !important;

And here is the actual html generated by ZK that creates that processing dialog if you wan to look for it or see the html that creates it :

<div id="g4fX_" class="z-temp"><div id="zk_proc" class="z-loading"><div class="z-loading-indicator"><span class="z-loading-icon"></span>Processing...</div></div></div>

Here is the top of my zul files now :

<?page title="Example Zul"?>
<?style src="/stylesheets/myStyleSheetToFixProcessingIssue.css"?>

Additionally, if you have a window type defined in lang-addon.xml like I do :


I moved the definition of the sclass "dhIpadBaseWindowStyle" to the style sheet loaded via the <?style....?> tag, that sclass sets my background to black. This final step eliminated all white flashes on the desktop and ipad.

    .dhIpadBaseWindowStyle .z-window-content
    background: #000000 !important;
    padding: 0 0 0 0;
    margin: 0 0 0 0;
