I have a dialog that has a few controls as well as a complex custom
view that itself contains other controls as subviews. The custom
view (for various good reasons) is instantiated and added as a
subview in code. A template view and NSView's replaceSubview:with is
used so the positioning etc can be set in the nib.
To fully support keyboard access, I need to somehow set things up so
that the user can tab from the nib-instantiated controls to the
controls within the custom view and then back out again. How can I
achieve this?
I'll also (presumably) need to set up the nextKeyView-chain for the
controls within the custom view (composed of a hierarchy of subviews
with their own subcontrols...), but I think I have an idea of how to
do this.
While I don't manually set up any UI as you're doing, I found that in
some cases, I still needed to programatically rewire the key loop.
This was especially so for complex screens involving nested tabless
tab views.
To manually rewire controls, look into the setNextKeyView: API.
If you then have tab views, you may need to provide an implementation
of tabView:didSelectTabViewitem: and rewire controls based upon the
new selected tab.
Also inside of tabView:didSelectTabViewItem:, I had to sometimes reset
the window's firstResponder. But, make sure to first ask the view if
it can be the first responder using canBecomeKeyView.
