Re: Struggling with NSTextView in a custom view

Hi,

I almost got my custom view working now. There is one thing that I don't
understand yet. My custom view has an NSScrollView in which I have an
NSTextView plus an NSView for a left margin (for linenumbers). I do the
following:

// create a frame for the left margin
    frame.origin = NSMakePoint(0, 0);
    frame.size = [scrollView contentSize];
    frame.size.width = left_margin_width;

    margin = [[NSView alloc] initWithFrame:frame];
    [scrollView addSubview:margin];

// create a frame for the text view
    frame.origin = NSMakePoint(left_margin_width, 0);
    frame.size = [scrollView contentSize];
    frame.size.width -= left_margin_width;

// make the text view and add it to the scrollview
    textView = [[NSTextView alloc] initWithFrame:frame];
    [scrollView setDocumentView:textView];


The problem is that the textView always starts at the left side of the
scrollview, instead of at left_margin_width. This is because I use
setDocumentView instead of addSubview. If I use the latter, then the margin
and the text are positioned ok, but the scroller doesn't respond to changes
in the textview.

How can I solve this?


thanks,

- Koen.
