After enough trying there, I went to #macdev instead, looking for alternative thoughts. Fortunately, someone there was finally able to understand the question, but only after dozens and dozen of lines of IRCing in a PM. He gave some pointers, and now it's all worked out. However, in the mean time, another user in #macdev started bitching at me about reposting the question when I already supposedly got loads of answers in #iphonedev (which I most definitely did not). I say bitching because he wasn't just politely reminding me that re-posting question is frowned up. His words were of a condensing sort, and he was _bitching_ about it. So, I said fuck you, /ignore, and put him on /ignore Immediately after that, the admin RTFM_FTW banned me, and he's not willing to lift it. I get banned from #iphonedev and #macdev on a very regular basis. Don't quote me on the numbers, but I think it's something like once per month, sometimes maybe more. Every time it's by this abusive admin RTFM_FTW. I've had open disputes with him in the past. Eventually I politely told him that I didn't think we should interact anymore, and then put him on a permanent /ignore in my IRC client. But the bans keep coming anyway :-/ I feel that I'm being discriminated against. The bans keep coming from RTFM_FTW, and from nobody else. I wish I could put some sort of injunction on RTFM_FTW banning me, because I'm certain no other admins would. I'm not really sure what to do here. I'm really missing #macdev/#iphonedev right now :-( -Patrick P.S If you're on here RTFM_FTW, fuck you. Just leave me the fuck alone already. I don't want to talk to you, and you don't want to talk to me; we don't like each other, and that's fine. But stop fucking banning me already, it's an abuse of your position. Feel free to ask another op to ban me, and if that other op feel that it's fit, then I'll be fine with a ban from _them_. But I doubt that's likely to ever happen, because 90% of your reason for banning me is due to the lasting dislike of me that you have from that time I talked back to you earlier this year in #macdev, so just quit it already, please! ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [iPhone] How to scroll to UITableView footer view

Re: [iPhone] How to scroll to UITableView footer view
contentSize is the correct way to do this. It gives a ‘buffer zone’ at the top and bottom (and sides if you wish) on the scroll view.

hi anyone out there,

i can't find any graphics clipping problems or something like that
i have looked for something that tells the scroll bar to be vertical or

does that automatically
i think i can see a horizontal bar stuck in a little piece of the vertical
slot, and a vertical bar stuck in the horizontal slot
the slots are correct in size, but the bar hasn't re-jiggered to fit the slot
does anyone know what is going on?
Your problem is unrelated to the NSScroller problem I'm experiencing. However,
looking at my code I'm not doing anything special when I create my NSScrollers
to make them horizontal or vertical other than giving them the correctly
oriented frame rect. For example if the frame rect is wider than it is high
then I get a horizontal scroller. I'm not sure that helps, but it might pay to
check the your frame rects are correct.
Here's a snippet of my creation code. As you can see it's pretty
straightforward:
m_scroller = [[NSScroller alloc] initWithFrame:boundsRect];
m_nativeControl = m_scroller;
if ( m_scroller != nil )
{
SetMinValue( inParams.minValue );
SetMaxValue( inParams.maxValue );
SetValue( inParams.initialValue );
[m_scroller setEnabled:YES];
if ( inParams.smallVariant == uctrue )
{
[m_scroller setControlSize:NSSmallControlSize];
}
[m_nativeControl setAutoresizingMask:NSViewMinYMargin];
[[macWindow contentView] addSubview:m_scroller];
}

IB Plugin Container View and child management
Dear list members
I have created in IB Plugin based on the Xcode template and everything works
fine.
If you need the completly boring source to help me out I can upload the full
project somewhere.
Here's what I'd like to accomplish:
I have a custom NSView subclass that is configured to be a container for other
objects.
Exposing child objects using - (NSArray *)ibDefaultChildren works as
expected.
Now I want to be able to drag other Library Objects from my IBPlugin inside the
container but limiting
the objects to certain classes.
How does IB determine the possible drop locations for dragged library objects?
I have implemented:
- (void)ibDidAddToDesignableDocument:(IBDocument *)document
{
NSObject *parent;
parent = [document parentOfObject:self];
NSLog(@ibDidAddToDesignableDocument: %@, document);
NSLog(@ parent: %@, parent);
// Try to remove ourself when added to the wrong parent
if ([parent isKindOfClass:[self class]] == NO) {
[document removeObject:self];
NSLog(@removed);
}
}
I assumed (wrongly) that I might be able to check the parent object and remove
the
just-added instance, but that leads to a nice assertion failure in IB.
Is there any way for a object to refuse itself to be dropped in certain
locations?
Thanks a lot
Patrick

Re: Strange NSScroller sizing behaviour
Hi,
Further to my original post, I've done some more investigation. I wrote a pure
Cocoa app (i.e. without my C++ UI framework code getting in the way) and still
experienced the resizing problems. The problems seem to effect scrollers which
are placed at the bottom or right edges of a window with a resize control, as
you would for scrolling window content. A scroller which was away from that
area resized as expected. After a bit of messing about I found that placing the
scroller inside an NSView and adjusting the scroller frame when the NSView
frame changed largely solves the problem. Vertical scrollers seem fine but
horizontal ones are sometimes off by a pixel or two after resizing. I can live
with it for now.
I don't think the NSScroller resizing behaviour is what it should be so will
file a bug.
In case anyone has a similar problem here is some code to give an idea of what
I'm doing. handleFrameDidChange: is a handler for the
NSViewFrameDidChangeNotification, where the scroller frame is updated. I should
probably also handle the bounds change notification.
INTERFACE CODE
@interface UCMacNSScrollerView : NSView
{
NSScroller* m_scroller;
}
- (id) initWithFrame:(NSRect) frame;
- (IBAction) handleAction: (id)sender;
- (void) handleFrameDidChange:( NSNotification* ) note;
@end
IMPLEMENTATION CODE
#import UCMacNSScrollerView.h
@implementation UCMacNSScrollerView
- (id) initWithFrame:(NSRect) frame
{
self = [super initWithFrame:frame];
if (self)
{
CGFloat width = NSWidth( frame );
CGFloat height = NSHeight( frame );
NSRect bounds = NSMakeRect( 0, 0, width, height );
m_scroller = [[NSScroller alloc] initWithFrame:bounds];
if ( width = height )
{
// NOTE: The NSViewMinYMargin flag here may not apply
to you, as I need to deal with the top left origin my UI framework uses
[m_scroller setAutoresizingMask:NSViewMinYMargin |
NSViewWidthSizable | NSViewMaxXMargin | NSViewMinXMargin];
}
else
{
[m_scroller setAutoresizingMask:NSViewMinYMargin |
NSViewHeightSizable | NSViewMaxYMargin];
}
[self addSubview:m_scroller];
[m_scroller setTarget:self];
[m_scroller setAction:@selector( handleAction: )];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector( handleFrameDidChange: )
name:@NSViewFrameDidChangeNotification object:self];
}
return self;
}
- (IBAction)handleAction: (id)sender
{
// Handle scroller action here
return;
}
- (void) handleFrameDidChange:( NSNotification* ) note
{
NSRect frame = [self frame];
NSRect scrollerFrame = [m_scroller frame];
scrollerFrame.origin.x = 0;
scrollerFrame.origin.y = 0;
scrollerFrame.size = frame.size;
[m_scroller setFrame:scrollerFrame];
return;
}

Re: Including UIImageView to Scroll down with UITableView
Your explanation of what you are doing now is incredibly vague (what do you mean by placing a UIImageView above a UITableView?) but I assume the answer you're looking for is to set your image view as the tableHeaderView.

Much like you'd see in iTunes when a song is too long to be displayed or how the modem connect NSStatusItem will scroll the words dialing... authentication I tried to simply write text to the menu bar using a Timer writing one character at a time, but the result isn't smooth and due to spacing in between letters can be variable in how much it moves each iteration. I suspect that a custom NSView is set to the NSStatusItem, but I am at a complete loss as to how to pull this off. Any examples of how to: 1. Properly animate the text. 2. Attach the resulting animation to the menu bar would be greatly appreciated. I have googled around extensively and have yet to find a solid example or clue.

Re: CoreData in predicate

theme sets with NSUserDefaults
Here's the scenario.

Here's an example to illustrate the idea. On the preferences page there is a combo box, where the user can pick a theme or enter the name of a new theme. The settings for the theme are some check buttons which have different states for the different themes. Obviously, the current state is easy with NSUserDefaults.

Dictionaries cannot contain nil values, but -objectForKey: will return nil if the key doesn't exist. Anyway, are you sure that oneClass is non-nil in you code? Have you stepped through the code using the debugger to see if the values are what you expect, and are being added to the dictionary properly? What happens after I adding an oneClass MutableArray Object to the parsedClasses MutableDictionary and how can I preserve the oneClass objects in parsedClasses after removing all objects? NSDictionary copies keys and retains objects, so you should never lose them if an owning collection releases them. Also, objects are not automatically removed from a collection when their reference becomes invalid (completely released). Chances are, they are not getting added to the dictionary at all.

Re: My program causes MacBook Pro to use NVidia graphics processor
Not particularly. I mean it is a graphics based program, but we don't have animations going on while the program is just sitting there, and we don't use any opengl or anything like that. Even when the user is interacting with it, it's just normal screen redraws - nothing I would have thought would be particularly taxing graphically. I'm a bit mystified as to why the machine would think that it needs the most advanced graphics chip available.

Re: Selecting an object based on the value of one of its attributes
Roland, the application in question uses Core Data. To build a dictionary as
you suggest, I will need to wait until the array controller loads its content,
then iterate over all members of the array, putting the property in question
and the array index into the dictionary. How can I know immediately (without
any user action) that the content has finished loading? I can't use
awakeFromNib, as the content has not yet been loaded when that method is called.

You could use NSPredicate to filter your collection based on your unique
string property being equal to the one sought. If they are unique it will
return exactly one item (or none, if it doesn't exist).
See [NSArray filteredArrayUsingPredicate:]
It's unclear whether that would be actually any faster than doing a linear
search yourself - it might be slower, in that it wouldn't return as soon as
it found the item, but would always check every element.
--Graham
I think that as Graham suggests that would be slower than searching yourself,
but it is a method and it does exist and it's free, so you could try that
and if it's fast enough for you, that's great.
Actually iterating the list however yourself is very simple and possibly
only the same number of lines of code as making a predicate. (code typed in
mail)
YourObject *found = nil;
for( YourObject *obj in yourArrayOfObjects )
if( [ [ obj thePropertyYouWant ] isEqualToString:yourThing ] )
{
found = obj;
break;
}
// if found isn't nil, you found one, if it is, you failed.
Finally - are these all your objects and are you always looking for the same
property of them? If so instead of dumping them into an array you could build
a dictionary of them as you insert them, keyed by that string property, then
go look it up later when you want it.

Using Xcode 3.1.3 (or 2.5), I created a standard Carbon application with a single document window. After running the application, I use the Display System Preferences to move the menubar from one display to another one. The document window for the Carbon application followed the menubar and moved to the other display. Doing the same thing, but this time with the default Cocoa application, the document window does not automatically move. Is there a way to configure a Cocoa window so it will follow the menubar to another display? I'm assuming there isn't as I have not seen such an option...unless I missed something. I assume the appropriate way to handle this in Cocoa is to respond to NSApplication's -applicationDidChangeScreenParameters: delegate method and move the window myself. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

How can I know immediately (without any user action) that the content has finished loading? I can't use awakeFromNib, as the content has not yet been loaded when that method is called. This sounds like something that should be happening at the model layer, not at the controller layer. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Is there something that I specific I may have in my application that would force it to use that graphics card? I've read in reviews that the new MBPs will switch graphics chips based on the frameworks apps link against. So your app may be linking (directly or transitively) one of the trigger frameworks. I don't know what's on that list besides, of course. OpenGL. You can set the environment variable DYLD_PRINT_LIBRARIES when starting your app, and all the libraries loaded will be spewed to stderr as it launches. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I suspect this is done to Carbon apps to keep them from breaking, since otherwise the window's global coordinates would change behind its back. Back in the day (during OS X 10.0 development) there were a lot of problems with having non-app code move Carbon windows, which is one reason why they're not draggable while the app is busy. So in short, this is a workaround, not a feature. I wouldn't expect an app window to move to follow the menu bar. But maybe your app has some special behavior that makes that behavior desirable? Your idea of the NSApp delegate call seems like a good way to implement that. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I have not verified any of this independently, and I am only assuming that running my program is the only thing that has changed, and that it is not just a temporary switch while the application is starting up or something like that...I'll do what I can to check that, but I think from the replies so far it appears that the operating system chooses what it chooses and you can't control that directly. Anyway, I don't think that I'll spend a lot of time on this since there is a new version of the program that links against different libraries etc due out next week. I'll see if this user still has the problem with that version. I see from Jens' reply, that I could try DYLD_PRINT_LIBRARIES, but it would perhaps not be very useful until I know what I am looking for, and we're not going to update the old version of the application anyway. If anyone does know if it is specific libraries that do this, and can provide a list, maybe I can check the new application against that list and possibly make some changes if required.

In regards to both of these (and especially the QC option). Would it be possible to add those to the NSMenu as with a setView?

Undo Action Message
I have a core data document based application. The standard 'Undo' menu sends an 'undo:' action message to the first responder. The message is passed along the responder chain to the window's delegate which is an NSPersistentDocument instance and then apparently to the NSManagedObjectContext instance. How does the 'undo:' action message actually get to the managed object context instance's 'undo' method? NSPersistentDocument and NSDocument are in the responder chain but do not have an 'undo:' method. NSManagedObjectContext is not in the responder chain but has an 'undo' method. However 'undo' is not the same as 'undo:'. --Richard ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Core Data Versioning: Non-trivial Value Expressions?
When doing Core Data versioning, when creating a Mapping Model, when writing Custom Value Expressions, I understand that the syntax to be used is that described in the Predicate Programming Guide Predicate Format String Syntax. But I can't figure out how to do non-trivial mappings like these... Example 1: Old data model attribute type is an Integer16. I want to map this to a Boolean which is NO if the old value was 0 and YES if != 0. Example 2: Old and new data model attribute types are both String. If the string is Joe, I want to map it to Jose; else, map the original value. It seems like the concept of mapping should support stuff like this, but I can't find any such examples. In MigratingDepartmentAndEmployees, all I see is mapping from one attribute name to another. Relations get a complicated expression like this generated automatically: FUNCTION($manager, destinationInstancesForEntityMappingNamed:sourceInstances: , EmployeeToEmployee, $source.employees) but I have no idea where that FUNCTION keyword comes from (it's not listed as a reserved word in the Predicate Programming Guide). It seems like I should be able to make my own FUNCTION to implement the stuff I need in my examples. Is this possible?
