Hello cocoa-dev,
Basically, i'm trying to do a little debug console. I'm using the
NSTextView in NSScrollView from Interface Builder.
I've got a Print member in my window's controller class which
basically does:
[TextView setString:[[TextView string]
stringByAppendingString:newString]];
What I want is for the horizontal size of the NSTextView part to
expand to the length of the string. I'm guessing NSTextView already
knows about \n and how to make a suitable rectangular area out of a
string.
I've set the Text View portion to be horizontally and vertically
resizeable. I've also made sure it's only autosizing vertically, so
that the Scroll View will show a horizontal scroll bar.
By default, it doesnt work. I add text with Print, and it always
wraps. If I size my window (which resizes the ScrollView) wide
enough, the text goes onto one line. When i size it smaller, the
horizontal scroll bar appears as expected.
I have tried calling sizeToFit after the setString, but it doesn't
do anything.
This is probably a really simple job, but i'm out of ideas! I'm just
starting with Cocoa, really.
The text view only displays the text that's laid out by other objects.
In this case, the one you need to modify is the text container.
To get the text container, use [textView textContainer].
Then, set its size to something huge in width, say 10000 (-
setContainerSize:). Call -setHeightTracksTextView:YES and -
setWidthTracksTextView:NO, and I think that should do it.
