In my app, I have a custom view which I'm printing. The NSPrintPanel has an accessory panel attached with a couple of options on it that I'm observing using the NSPrintPanelAccessorizing method -keyPathsForValuesAffectingPreview. That works fine.
When the user changes some of the settings, the size (ie, frame) of the view
changes (columns are added/removed from an NSTableView in my custom view).
When that happens, the preview doesn't get updated correctly: it uses the frame
of the view as it was when the NSPrintOperation was created. That means that
the preview panel doesn't show the correct image of the page to be rendered.
Is there a way to notify NSPrintOperation that the frame size has changed on
the view to be printed?
I've tried all sorts of fiddling with the frame and bounds of the view to try
to get it to display to no avail.
I'm really stuck so any help would be appreciated, as by my customer who is
very frustrated at how long this detail has taken resolve.
Thanks,
Ben.
