375572 - Printing does not display the "processing" dialogue

Status: NEW

(Core :: Widget: Cocoa, defect, P3)

Description

[Smokey Ardisson (offline for a while; not following bugs - do not email)]

In Mac apps, when you press the "Print" button in the print dialogue/sheet, there's supposed to be a "Print" dialogue that displays a progress bar and has text about "Processing Page 1..." until the "processing" is done.

Even since we switched to Cocoa printing, this has been missing.  It's visually quite odd and a bit disturbing, since you wonder if printing is really working, especially if you've experienced the last several months of trunk printing ;)

This is quite bad when you're saving a page as a PDF file, because you would want to know if the file is finally saved before you open it.

Markus, can you have a look at this ?

That's exactly the case that brought this bug up in the forum tonight:  

"I bring this up because I was saving a page as a PDF and trying to open the file but it kept telling me that the file could not be opened. I found out that this is because the save simply wasn't finished, as it seems to take several (5+) seconds for the save to finish (this was a 21 page article filled mainly with text, on a MBP 2.53ghz). This strikes me as a usability issue because it's not telling the user what's going on."

Josh, is this something that new printing dialogs will take care of?

I don't think we'd block on this, considering printing still works.

I don't think the new printing dialogs take care of this bug Markus would know better. I don't remember why we weren't inheriting this behavior from the OS.

I don't know either. Cocoa probably gives us APIs for showing that dialog, and our cross-platform printing code has progress APIs which our Mac code doesn't use, but I'd have to spend more time to find out the details.
I probably won't get to this any time soon, sorry.
