    <p>I added a childWindow of a custom subclass of NSWindow to a parentWindow (also a custom subclass of NSWindow). The childWindow has the NSBorderlessWindowMask and canBecomeKeyWindow: is overridden to return YES and canBecomeMainWindow: to return NO.</p> <p>The childWindow is set to resize with the parentWindow. So I want to create the illusion that the views of the childWindow are part of the parentWindow. The main idea is to arrange the document windows created by the document-based application within a main window to provide a tabbed interface (just like in a browser) to switch between the documents.</p> <p>My problem is that whenever I click in one of the views of the childWindow, the parentWindow (the main window) looses focus and the traffic light buttons are getting greyed out. This is obviously contrary to what I want to achieve.</p> <p>I found this answer: <a href="https://stackoverflow.com/questions/4916100/make-nsview-in-nspanel-first-responder-without-key-window-status">Make NSView in NSPanel first responder without key window status</a></p> <p>But even if I override isKeyWindow: (of the main window) to always return YES, the title bar gets greyed out nonetheless when I click into the childWindow.</p> <p>I also tried to follow this advice: <a href="http://www.cocoabuilder.com/archive/cocoa/143945-non-focused-child-window.html" rel="nofollow noreferrer">http://www.cocoabuilder.com/archive/cocoa/143945-non-focused-child-window.html</a></p> <p>But I'm not sure what "include the child window in its responder chain just ahead of its nextResponder" means. With canBecomeKeyWindow: to return NO (for the childWindow), the views within the child never can become key and are always greyed out.</p> <p>Any clue what I am doing wrong?</p> <p>One addition: Is it possible to make the views in the childWindow FirstResponder without giving the childWindow key-status?</p>

    1. COIs there a reason you're not simply using a tab view (with the tabs turned off, if you'd rather use a custom tab-switcher view) to switch amongst the different views?

    2. CO@PeterHosey: Yes, the document-based application creates windows for each document. It would be extremely difficult to hack the document-based application architecture to make it produce views for each open document. The effort would essentially mean to completely rewrite the document architecture. I would like to avoid that, because it will be error-prone and I would have to implement all the features coming with future OS X versions myself. I guess it would not be worth the effort. But at the same time I think that a tabbed-based application is a good approach for my program.

    3. COYou could override `makeWindowControllers` to make a view controller and add its view to the nearest existing window (if there is one) instead.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
