Center Align Document Extension

Brian_Munz — Mon, 26 Jan 2026 16:26:21 GMT

I've often heard requests for an extension that can center align a QlikView document, and I recently built one for the Global Games app.

One difference between that one and the one I'm posting here, is that that version also places a new background image on the page.

So, non-technically, this extension will take your app and align it to the center of the window, including the tabs. It also centers any background image on the app as well, so if you have a background image that is wider than the content area of the app, it could cause that background image to look strange.

A little more technically...since QV uses all absolutely positioned elements, it's difficult to determine the width of the content area, but I was able to do that in this extension in order to center it. The one issue is that if there is a smaller width the content area, it will center based on that small area and look strange. So, the default width that it sets the document to is 1024 pixels. If the extension determines the app is wider, it will center properly for that width.

Even more technically...all the extension is really doing is wrapping the content area (the PageContainer div) inside a div with a class of "master." Then, the extension just determines the content area width, and centers that content in the master div.

ANYway, hopefully this helps some people out. I haven't tested in QVS yet, but it should work in QVS also.

Thanks.

EDIT: I modified the extension I originally posted to ensure the aligning updates when switching between sheets of different widths.

It calculates initially for the first sheet?

because when switching between sheets/tabs the centering is not adjusted, when objects are wider.

Still good extension and can help in some situations

or maybe it has to do with the container objects because sheets with containers give the problem.

Good catch. I've fixed the extension and updated it on here.

Looking good, but if you can do this, then you can also make it autozoom!

Typical Qlikview User, give them a finger and they want the whole hand.........

This is what we qlikview designers are looking for, because in webview (AJAX) the macro's don't work.

Maybe it's better to make it in another extension so we can select them both of single.

You make me smile, thanx for this extension!

Oof, autozoom. The main problem with autozoom is Firefox. I could easily get some sort of extension set up for it (in fact I have one that was nearly complete) but Firefox deals with zooming differently than other browsers so it'd be much more of a pain in the neck than I was willing to deal with at the time

I'll keep you posted, though, if I ever get anywhere with it.

Thnx Brian!

This autozoom feature that people seem to want...would it simply zoom in so that the QVW's width fit into the screen, or would it zoom to as high of a level as it could while keeping all objects in view?

Zoom fit to window Same as possible in THE qv designer

Hi,

I'm fairly new to the noble art of Qlikview extensions and I was wondering if somebody could explain how to use this extension?

I installed it, use the webview mode and create the object... then what? I'm lost

Re: Center Align Document Extension

jochem_zw — Thu, 02 Aug 2012 08:22:26 GMT

you have to go to document properties, extensions (tab), there you can activate it.

Ah okay so it's not an object... Thanks

Re: Center Align Document Extension

jochem_zw — Thu, 02 Aug 2012 08:27:07 GMT

it's a document extension, not an extension object

Re: Center Align Document Extension

Thu, 02 Aug 2012 08:44:56 GMT

Ok, got it working now. Thanks.

jochem_zw,

I finished a document extension which does the zoom to fit window.

Let me know if this was what you were looking for.

jochem_zw — Fri, 03 Aug 2012 19:27:37 GMT

Was just downloading it!

Thanx will see if it does what I think it needs to do!

Yeah it's not going to be exactly like the designer one by any means since I have to use web technologies to do the zooming.

This is a great extension and has bugged me since using Qlikview that i couldnt center my app.

On my current project however, i needed to hide my tabrow and noticed that when i use this extension, it pops my background down a few pixels. i cant tell if its bumped down to compensate for the tabrow, or its some kind of bug related to how im using my background (background is a tiled image 1 pixel length wide stretching across page).

as soon as i remove and then apply the background it then looks the way its suppose to.

any thoughts?

I love this app! One question in the Global Games app you made how did you set up the new background image on the same page?

Great extension!! Thanks Brian.

Just for info, I had to replace the entry "qvtr-tabs" with "qvtr-tabs-wrap" to align the Tabs too. I'm using the 11.20.

Thanks again Brian for sharing your work.

I have implemented this extension and it works fine on desktop browsers. We have users using Good For Enterprise on iPad and dashboards with this extension were very slow. Performance was restored after we have removed this extension from the dashboard. Looks like on GfE the browser was constantly realigning objects.
