Dialog over pdf document embedded in iframe does not display correctly

[rotoflex]

Dialog does not display correctly in Firefox (3.5.2) when it is displayed over pdf document embedded in iframe. Dialog content displays over pdf document but titlebar and small portion of dialog's frames stay under pdf document.

When ui-dialog-content and ui-widget-content are added as titlebar's class, titlebar displays correctly but this also causes dialog to lose it's draggable effect.

Could be something about position:relative. A testpage would be nice.

It seems that in Firefox 3.5.5 (Linux) it will render div content on top of PDF plugin if it has overflow:auto (or one of overflow-x or overflow-y set to auto). Adding this to .ui-dialog style improves the rendering (border and padding of dialog are still hidden), but it also make dragable dialogs movement erratic. Solution seems to be that we need to envelop the whole ui-dialog into another div (sizing of which needs to be handled manually, not sure how well moving/resizing would work). This wrapper div need have no style other than overflow:auto, but we must be careful not to actually produce any scrollbars around it

In case of using modal dialogs, then just the overlay needs overflow:auto. Note that this will cause all of PDF plugin to hide when overlay is placed on top of it (as if it's replaced with a transparent div)

Please provide a reduced test case showing the problem so we can see how you're embedding the pdf.

Hi,

Here's test case for this ​http://jsbin.com/imevek. As you can see page contains simple iframe with pdf embedded in it. If you drag dialog over pdf you'll see it will go behing iframe. I've tested this with IE9, Chrome 18.0.1025.168 and Firefox 12.0 and Firefox is the only browser that dialog will stay on top of iframe.

Regards,

Janne

Works for me in Chrome 20, Chrome 18 just downloaded the file instead of displaying it.

Strange, my Chrome 18 displays pdf instead of downloading it. I noticed that if I use Chrome's internal PDF viewer dialog stays on top but with Adobe Acrobat is will stay under iframe.

Unfortunately most of our clients use Internet Explorer from version 7 to 9 so it would be really helpful to get this working on it.

Is there a reliable way to reproduce this? What software exactly has to be running?

[mikesherov]

joern, see comment 6 for a test case.

[Jörn Zaefferer]

That works fine in Chrome 23 on OSX. In Firefox 16, it starts downloading the PDF, and there's still nothing on top of the dialog.

[mikesherov]

​http://jsbin.com/imevek shows the failure in IE9 on browserstack for me. However, I really think this should be a wontfix, as pdf display isn't really part of the "web", so to speak, and the fix would involve yet another iframe hack. Thoughts?

Jörn: I think you'd need to install the Acrobat plugin to see the broken behavior.

But, as was discussed recently (and mentioned by Mike above), we won't support this.
