Hi Andrea,
If you need to have multiple copies of an NSTextView, try creating a
master copy in Interface Builder. Put a view in the nib file and
inside the view include an nstextview, which will automatically
generate the necessary scrolling stuff.
Now sublcass NSObject and make your subclass the nib file owner.
Inside the init method of your subclass, have it claim the nib file
using [NSBundle loadNibNamed:@"MyNibFile" owner:self];
Also in your subclass, include a method that returns that main view.
Then, whenever you need to add another text view to a tab, initialize
your subclass, grab the main view that contains the text and scroll
views using your custom method, and add that main view to the tab.
Hope that makes sense!

Hi to all,
I need to create dynamically a certain number of tab that keeps
inside an istance of nstextview.
NSTextView *chatView;
int a = [theTabView indexOfTabViewItemWithIdentifier:aNick];
if (a == NSNotFound)
{
id * lastTab;
NSTabViewItem * thePvtTab = [[NSTabViewItem alloc]
initWithIdentifier:aNick];
[theTabView addTabViewItem:thePvtTab];
[thePvtTab setLabel:aNick];
NSScrollView *scrollview = [[NSScrollView alloc]
initWithFrame:NSMakeRect(0, 50, 500, 500)];
NSSize contentSize = [scrollview contentSize];
[scrollview setBorderType:NSGrooveBorder];
[scrollview setHasVerticalScroller:YES];
[scrollview setHasHorizontalScroller:NO];
chatView = [[NSTextView alloc] initWithFrame:NSMakeRect(0,
0,contentSize.width, contentSize.height)];
[chatView setVerticallyResizable:YES];
[chatView setHorizontallyResizable:NO];
[chatView setAutoresizingMask:NSViewWidthSizable];
[chatView setMinSize:NSMakeSize(0.0, contentSize.height)];
[chatView setMaxSize:NSMakeSize(1e7, 1e7)];
[chatView setDrawsBackground:TRUE];
[chatView setBackgroundColor:[NSColor whiteColor]];
[chatView setEditable:TRUE];
[chatView setRichText:TRUE];
[chatView setSelectable:TRUE];
[[chatView textContainer] setContainerSize:contentSize];
[[chatView textContainer] setWidthTracksTextView:YES];
[scrollview setDocumentView:chatView];
[thePvtTab setView: scrollview];
[theTabView selectLastTabViewItem:(id)lastTab];
[chatView insertText:aMess];
}
else
{
NSTabViewItem * thePvtTab = [theTabView tabViewItemAtIndex:a];
NSScrollView * scrollview = [thePvtTab view];
chatView = [scrollview documentView];
[chatView insertText:aMess];
}
}
When I run the app all works (the threads too), but if a scroll the
textview after some lines the app crash!
I think the problem is NSScrollView NSMakeRect
Where the last 500 is wrong...
How can I modify it to mantain the scroll infinite?
