When the outline has focus, arrow keys navigate the outline instead
of changing the current page.
Add opt-up and opt-down as a way to move by one page even when the
outline has focus. (This matches Preview.app.)
xib change: Added two menu Previous Page with key equivalent opt-up
and Next Page with key equivalent opt-down to Go menu and bound them to
goToPreviousPage: and goToNextPage: on First Responder.
When the outline has focus, the responder chain is outline ->
window, so also add the actions on the window controller, and
let that forward to the PDF view.
Clicking an item in the outline now opens that page.
This requires giving the outline view a delegate, which for some
reason also has th effect of indenting expandable items ¯\_(ツ)_/¯
The vertical alignment of text still looks off, though.
- MacPDFWindowController is now the xib file's owner
- _pdfView moves over
- MacPDFWindowController is now the MacPDFViewDelegate and responsible
for updating the window's title
- Due to MacPDFWindowController now being the xib file's owner,
windowControllerDidLoadNib: is no longer called automatically,
so call a custom windowIsReady method manually instead
No behavior change.
I'd like to add a sidebar, and NSSplitViewItem apparently isn't
accessibly in .xib files without contortions. So I want to move
to creating the window in code, and this is a step towards that.
No behavior change.
