Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo
I’ve found the Text Storage like this: NSTextStorage* myTextStorage; myTextStorage = [[self.pLogScrollView documentView] textStorage]; > You can control trucation behavior in an NSTextView by using NSTextStorage, > which is a subclass of NSMutableAttributedString. The truncation methods are > in NSParagraphStyle). But when I look in NSTextStore Class Reference I can see nothing relating to setting paragraph styles? There’s a “paragraph” property but it says: Special Considerations Unless you are dealing with scriptability, you should not invoke this method directly. I can’t believe its this hard to set wrapping or not and I can’t find real info on this from searching either. Does anyone have some code that does this or something similar?

Code to Stack or Tile Windows
Hi All, I seem to remember there being some sample code available to stack or tile windows to a particular screen. Is this still available somewhere or are there any built-in Cocoa methods to do this? I can easily write it myself but if there something around that does the job I’d rather use it if possible. Basically I just want to place some Windows Tiled to a Particular Screen. Thanks a lot.

For your purposes, the key point is that NSTextStorage is a subclass of NSMutableAttributedString, which is in turn a subclass of NSAttributedString. You should be looking at methods like NSMutableAttributedString's -setAttributes:range:. Basically, you start by creating a dictionary of formatting attributes, then you provide it to -setAttributes:range: with the range of characters to which you want those attributes applied. That's why they're called "attributed" strings -- they are strings with formatting attributes. Look at the introduction to the NSAttributedString technical reference document, the NSAttributedString AppKit Additions reference document, Text Attribute Programming Topics, and the Attributed String Programming Guide. The "Paragraph Attributes" section of the Text Attribute Programming Topics is especially pertinent to your question, including its cross reference to the much more detailed Ruler and Paragraph Style Programming Topics. -- Bill Cheeseman - wjcheese...@comcast.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo
Hi Bill, I’m familiar with NSAttributedString and friends. I had thought that there was a higher level interface to it as it seems like a common thing to want to do. Basically my ScrollView is just a scrolling line log similar to XCode’s NSLog window. I’m just appending an NSString to the Document View like this: myTextView = [self documentView]; [[[myTextView textStorage] mutableString] appendString:theString]; Should I convert “theString” to a NSAttributedString and then set the attributes of this string, or set the attributes of [[[myTextView textStorage] mutableString] ? The reason I ask is because the TextView can get large and I’m not sure if setting the attributes each time would slow things down?

Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo
I tried the following: myTextView = [self documentView]; [[[myTextView textStorage] mutableString] appendString:theString]; myRange = NSMakeRange(0,[[[myTextView textStorage] mutableString] length] - 1); [[myTextView textStorage] addAttribute:NSParagraphStyleAttributeName value:[NSNumber numberWithInt:NSLineBreakByTruncatingTail] range:myRange]; But this results in nothing being displayed in the ScrollView/TextView. I thought of appending an Attributed string to the Text Storage, but I can’t find a method that accepts an Attributed String, so not sure how I’m supposed to just set it to NOT wrap! If anyone knows the secret please let me know! Cheers Dave > On 25 Apr 2016, at 16:34, Dave wrote: > > Hi Bill, > > I’m familiar with NSAttributedString and friends.

Xcode Source Compiling Order Issue
My product is a System Preferences Pane. Its principal class is MyPrefPane and is defined correctly in the Info.plist file under NSPrincipalClass. The bug I am seeing happens when trying to install a new version over the top of an older one if (and only if) System Preferences is closed or System Preferences is open but the older pane has not been clicked on (and is thus not loaded). I get an error that my pref pane can't run on an Intel Mac and console reports: System Preferences[10232]: -[MyMinorClass initWithBundle:]: unrecognized selector sent to instance 0x7fc60be96170 System Preferences[10232]: [NSPrefPaneBundle instantiatePrefPaneObject]: error occurred during instantiation. It seems like System Preferences is trying to init my pref pane by loading a minor internal class instead of my MyPrefPane class. In Xcode Build Phases under compile sources, I noticed that the first two items are: MyMinorClass.m MyPrefPane.m If I reverse these, and compile MyPrefPane.m first, the bug is eliminated. Putting any other class before MyPrefPane.m results in System Preferences making the same attempt to call the first-compiled class with initWithBundle: Why does the compile order matter? I found a similar issue here: http://stackoverflow.com/questions/31373144/xcode-source-compiling-order-iss ue He solved it by rebuilding the project. I have just spent 8 hours rebuilding this complex project and still get the same results as before (this Xcode project has existed since Xcode 3) I am unable to reproduce this on a simple Xcode PrefPane template. Any ideas? I am not sure if this is an Xcode issue or something in the OS. For now of course all I can do is make sure the principal class is compiled first.
