Create NSScrollView Programmatically in an NSView - Cocoa

Question

I have an NSView class which takes care of a Custom View created in the nib file. Now I want to add an NSScrollView to the custom view, but I need to do it programmatically and not using Interface Builder (Embed Into Scroll View). I have found this code: ``` NSView *windowContentView = [mainWindow contentView]; NSRect windowContentBounds = [windowContentView bounds]; scrollView = [[NSScrollView alloc] init]; [scrollView setBorderType:NSNoBorder]; [scrollView setHasVerticalScroller:YES]; [scrollView setBounds: windowContentBounds]; [windowContentView addSubview:scrollView]; ``` Assuming I declare as IBOutlets the variables 'mainWindow' and 'scrollView' above, how would I go about connecting them to the proper components in Interface Builder? Does it make any sense to do it this way? Or is there a better way to add a scroll view programmatically? P.S. I cannot connect them in the usual way because I cannot create an NSObject Object from Interface Builder, or use the File Owner..

Accepted Answer

This code fragment should demonstrate how to create an NSScrollView programmatically and use it to display any view, whether from a nib or from code. In the case of a nib generated view, you simply need to load the nib file to your custom view prior, and have an outlet to your custom view (outletToCustomViewLoadedFromNib) made to File's Owner.

```
NSScrollView *scrollView = [[NSScrollView alloc] initWithFrame:[[mainWindow contentView] frame]];

// configure the scroll view
[scrollView setBorderType:NSNoBorder];
[scrollView setHasVerticalScroller:YES];

// embed your custom view in the scroll view
[scrollView setDocumentView:outletToCustomViewLoadedFromNib];

// set the scroll view as the content view of your window
[mainWindow setContentView:scrollView];
```

Apple has a guide on the subject, which I won't link to as it requires Apple Developer Connection access and their links frequently break. It is titled "Creating and Configuring a Scroll View" and can currently be found by searching for its title using Google.
