RE: protocol and properties
Then I implement a class which implements this protocol. To do that
I make a property:
@property (nonatomic, readwrite, retain) NSArray * objects;
and put the appropriate synthesize statement in the implementation.
I get compiler warnings that this class doesn't implement the
protocol. It seems it doesn't take the synthesized getter as being an
implementation of the -objects method.
I also tried explicitly adding the implementation, but the warning
remains:
- (NSArray*) objects
{
return objects;
}
Am I doing something wrong here, or is it not possible to use a
property to satisfy a protocol?
Yes, you are doing something wrong.
Here you are just using a method that you declared and implemented in a
protocol.
You need to tell a class where that method is declared and implemented, and
you do that like this:
@interface ClassIWantToUseSomeProtocolMethodIn : NSObject
MyProtocolThatIWantToImplement

Question about NSScrollView
Hi all ! So I have a question on how to resolve a little issue I have with NSScrollView. I have created everything programmatically (a little exploration task to learn and understand how to do stuff without IB). I have an NSOutlineView enclosed in an NSScrollView (as recommended by documentation). All works good except for little thing. Since NSOutlineView is not populated, content area is empty, but vertical scroller knob is shown (horizontal not showed). Question: Why ? I googled for an answer and got some facts together but don't really know how to get to the solution to rectify the issue. Facts: Scroller in this situation is shown because NSOutlineView has NSTableHeader shown (instantiated). If I set NSOutlineView headerView to nil, it gets released and not shown in the NSScrollView, and then there is no scroller knob. But what if I want to have NSTableHeader ? Seams to me that if the headerView is ON, NSScrollView makes wrong calculation of how much is the content area big and how much should it be shown. I have been examining the documentation for NSScrollView and NSClipView and found couple of methods that has something to do regarding that but I don't know to make a use of them. If any one knows something which could point me to the solution it will be much appreciated. Thanks in advance. Bye.

But then I could also remove headerView and evade the problem in the first place. What would be solution if I want to have vertical scroller visible ? I'm thinking more in the way of somehow recalculating contentView area before it gets send to the NSClipView to be displayed. Correct ? Wrong? Thanks for suggestions.

Re: make connections without InterfaceBuilder
Hello !
I don't know if this got answered but here is my attempt. It is just a
basic way of programmatically setting
an object as a application delegate and programmatically creating a
button on the applications main
window and setting it to perform an action when clicked.
I know that there are some issues about the way this is implemented
but it points the way to go.
Since I am a newbie my self any suggestions are more than welcome.
Brief explanation follows.
In Interface Builder:
- in MainMenu.xib create generic NSObject by adding it from the Library
- select that NSObject and in the Identity Inspector make it an
instance of our ApplicationController class
In Xcode:
- in awakeFromNib we make our self as the application delegate
- in applicationDidFinishLaunching: we tell the application to make
the first window that it finds as main
window, because at this time there is still no main window
- then we create our button instance, set its action as a selector
with our action method, set our self as a target of that action,
and perform all necessary initializations for our button (title, type,
etc)
- we add our button on the main window and then release the button
- in dealloc we remove our self as being application delegate
- okButtonAction: is our button's action method that performs NSBeep()
function
Code follows.
ApplicationController.h
#import Cocoa/Cocoa.h
@interface ApplicationController : NSObject
{
}
@end
ApplicationController.m
#import ApplicationController.h
@implementation ApplicationController
- (void)awakeFromNib
{
[NSApp setDelegate:self];
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
[NSApp makeWindowsPerform:@selector(makeMainWindow) inOrder:NO];
NSButton * okButton = [[NSButton alloc]
initWithFrame:NSMakeRect(10.0, 10.0, 96.0, 32.0)];
[okButton setAction:@selector(okButtonAction:)];
[okButton setTarget:self];
[okButton setTitle:@OK];
[okButton setButtonType:0];
[okButton setBezelStyle:11];
[[[NSApp mainWindow] contentView] addSubview:okButton];
[okButton release];
}
- (void)dealloc
{
[NSApp setDelegate:nil];
[super dealloc];
}
- (void)okButtonAction:(id)sender
{
NSBeep();
}
@end
Thanks.

Informations about Cocoa implementations of VDCP and MOS protocols
Hello to the list ! I'm wondering if anyone here ever came across of Cocoa or Objective-C implementations of VDCP and MOS protocols ? Google shows no results that would give me any references and examples about how could (should) this be done. I guess that nobody tried to make an open source version yet. There are companies that have their proprietary implementations but ... So, I would very much appreciate if anyone have any kind of documentation (beside official MOS protocol from their website), references (websites), examples or anything that could help me learning how to implement these protocols in my Cocoa application. Thanks in advance.

copyWithZone - if anyone could explain this to me ?
Hi !
I have some trouble understanding this implementation:
- copyWithZone:(NSZone *)zone
{
ImageAndTextCell *cell = (ImageAndTextCell *)[super
copyWithZone:zone];
cell-image = [image retain];
return cell;
}
It is from the Apple's sample code.
First question is why there is no return type declared in front of
copyWithZone: (probable - id - type) ?
Second question is what this sign stands (means) for: - (in cell-
image = [image retain];) ?
Could that line be written somehow different (like any other objc
message) ?
Basically, I'm asking for a child-like explanation of this
implementation.
Thanks for your answers in advance. Bye.

NSOutlineView - How to hide disclosure triangle for root nodes ?
Hello to all on the list. I have a little question so if anyone could help me. I'm have an outline view that has one (for now) object in root array that acts as a root from which all other objects derives. \/ Root Array |\/ Root object |- Child 1 |- Child 2 |--- \/ Child 3 |--- Child 3.1 |--- Child 3.2 |- Child 4 My question is: How to hide the disclosure triangle in front of the Root object and remove indentation for it, and just that object (and later if there is more Root objects for them too) ? \/ Root Array | Root object |- Child 1 |- Child 2 |--- \/ Child 3 |--- Child 3.1 |--- Child 3.2 |- Child 4 I would like it too look like source list in Apple's Mail application - where it says - MAILBOXES. I found the delegate method which is used for drawing outlineCell - (void)outlineView:(NSOutlineView *)outlineView willDisplayOutlineCell:(id)cell forTableColumn: (NSTableColumn*)tableColumn item:(id)item but that method does not get called if Root object is empty. There is a method that is also used for drawing outlineCell - (NSRect)frameOfOutlineCellAtRow:(NSInteger)row but it is not a delegate method which means that I should subclass NSOutlineView to implement that behavior. I'm trying to make it work with the delegate method (that would be my preferred way) but I can't make it work. Any suggestions what to do ? And how ? There is a zip archive of my project at http://www.box.net/crowebster-public so anyone interested can download it to review my work. P.S. additional question: If there is number of object that are identical (just added to the array but not yet modified), when one item is selected and removeItem method is called upon it, all identical objects are removed instead just selected object. How to avoid that behavior (the simplest possible way) ? Notice: All objects are instances of NSMutableDictionary. That problem is also in the same project. Any suggestions are appreciated.

Disregard that last question. I have just checked online documentation on Apple Dev site. It's Snow Leopard feature, not available in Leopard.

Re: NSOutlineView - How to hide disclosure triangle for root nodes ?
Hi !
So I have sub classed NSOutlineView and implemented single method like
this:
- (NSRect)frameOfOutlineCellAtRow:(NSInteger)row {
return row == 0 ? NSZeroRect : [super frameOfOutlineCellAtRow:row];
}
That works except the indentation problem is still on.
If root object is empty than it is indented (default in IB is 14), but
when I add child object to it,
root object indentation gets reset to zero (0).
How do I fix that ?
Bye.

Re: NSOutlineView - How to hide disclosure triangle for root nodes ?
Here's me again !
So I have found a different solution for my problem and it does not
include subclassing NSOutlineView,
but trough the use of two delegate method.
This is my implementation:
- (NSCell *)outlineView:(NSOutlineView *)outlineView
dataCellForTableColumn:(NSTableColumn *)tableColumn item:(id)item {
[outlineView rowForItem:item] == 0 ? [outlineView
setIndentationPerLevel:0.0] : [outlineView setIndentationPerLevel:14.0];
return nil == tableColumn ? nil : [tableColumn dataCellForRow:
[outlineView rowForItem:item]];
}
- (void)outlineView:(NSOutlineView *)outlineView
willDisplayOutlineCell:(id)cell forTableColumn:(NSTableColumn
*)tableColumn item:(id)item {
[outlineView rowForItem:item] == 0 ? [cell setTransparent:YES] :
[cell setTransparent:NO];
}
To explain:
In both methods I ask if row in question is the root. If it is, than
set no indentation and hide triangle,
otherwise set some indentation and show the triangle.
I believe that this is better solution than subclassing.
Still I have some issues to resolve. Work in progress.
Thanks everyone for their suggestions. If anyone is interested in
reviewing my code,
the project is in zip archive at http://www.box.net/crowebster-public.
Bye.

Re: NSOutlineView - Automatically select newly added item - Help needed
Hi all !
Thanks for your replies everybody !
I have reviewed my code according to yours inputs and I found where
the problem was.
Here's the reviewed code:
if ([lsOutlineView selectedRow] 0)
{
Parent *parent = [Parent new]; --- create new Parent
object
NSLog(@1 - %@, parent);
[sourceListLevelZero addObject:parent]; --- add newly created
Parent object to the root array
[lsOutlineView reloadItem:nil reloadChildren:YES]; --- reload
outline view
NSUInteger index = [lsOutlineView rowForItem:parent]; --- get the
row index of the newly created Parent object from the outline view
NSLog(@2 - %i, index);
NSMutableIndexSet *indexSet = [NSMutableIndexSet new]; --- create
new empty NSMutableIndexSet object
NSLog(@3 - %@, indexSet);
[indexSet addIndex:index]; --- add row index of the Parent object
to the indexSet
NSLog(@4 - %@, indexSet);
[lsOutlineView expandItem:nil expandChildren:YES]; --- expand the
root array objects and all of their children
[lsOutlineView selectRowIndexes:indexSet byExtendingSelection:NO];
--- select row with index number from the indexSet without multiple
row selection
[parent release]; --- release parent object
[indexSet release]; --- release indexSet
}
I assume this is correct way now because it works fine.
If someone has some objections, please state your comment, I am
interested to hear (learn).
I will (when I make this code actually do something useful) post a
link to the list for the entire source code so anyone interested to
review it (and point out my mistakes) will
be most welcome.
Since I have no idea how to use Instruments (and until I do) this will
be very helpful to me in future learning.
Thanks again.

Re: NSOutlineView - Automatically select newly added item - Help needed
Again me !
Just a little update !
I packed previous code in combined message calls.
Here's how it looks now:
if ([lsOutlineView selectedRow] 0)
{
Parent *parent = [Parent new]; --- create new Parent
object
[sourceListLevelZero addObject:parent]; --- add newly created
Parent object to root array
[lsOutlineView reloadItem:nil reloadChildren:YES];
[lsOutlineView expandItem:nil expandChildren:YES];
[lsOutlineView selectRowIndexes:[NSIndexSet indexSetWithIndex:
[lsOutlineView rowForItem:parent]] byExtendingSelection:NO]; ---
select row according to index from indexSet created with row index of
outline view for item - parent
[parent release]; --- release Parent object
}
Again this works fine.
Ok, that's it.
Bye !

NSOutlineView - Automatically select newly added item - Help needed
Hello to the list !
Request for help regarding a little problem.
So I have this piece of code:
- (IBAction)addNewItem:(id)sender
{
if ([lsOutlineView selectedRow] 0)
{
[sourceListLevelZero addObject:[Parent new]];
[lsOutlineView reloadItem:nil reloadChildren:YES];
[lsOutlineView expandItem:nil expandChildren:YES];
[lsOutlineView selectRowIndexes:[NSIndexSet indexSetWithIndex:
[lsOutlineView rowForItem:[Parent new]]] byExtendingSelection:NO];
}
...
}
It is the last line that trouble's me.
It should select newly added item in the list (right ?), but it does
not !
Or am I doing something wrong (very likely !) ?
Ok, so you got it by now that I am trying to get the behavior that
when user clicks add button new item that appears in the list
automatically gets selected.
Thanks for help

splitView not rendering correctly - where am I wrong ?
Hello everyone!
So I have a little problem that I don't know how to fix so if somebody
would be kind to help and explain the solution.
Problem is that splitView displays subviews that are rendered outside from the
visible area
of the window so therefore are clipped (not visible). They are clipped after
the splitView
has been resized in that extend that (only right subview and/or both) subviews
had been totally sized down.
When resized back up, top (of both subviews) and/or right part (of right
subview) are clipped.
My guess it has something to do with bounds and/or position of subviews, but
since I'm novice in Cocoa
and Objective-C I can't see the solution.
Here is the code that I'm using for displaying splitView.
Thanks in advance!
Mario

- (void)splitView:(NSSplitView *)sender
resizeSubviewsWithOldSize:(NSSize)oldSize
{
NSView *leftView = [[sender subviews] objectAtIndex:0];
NSView *rightView = [[sender subviews] objectAtIndex:1];
float dividerThickness = [sender dividerThickness];
NSRect splitViewFrame = [sender frame];
NSRect leftFrame = [leftView frame];
NSRect rightFrame = [rightView frame];
int differenceInWidth = splitViewFrame.size.width - oldSize.width;
leftFrame.size.height = newFrame.size.height;
leftFrame.origin = newFrame.origin;
if (differenceInWidth 0)
{
rightFrame.size.width += differenceInWidth;
}
else if (differenceInWidth 0)
{
rightFrame.size.width += differenceInWidth;
}
rightFrame.size.width = splitViewFrame.size.width - leftFrame.size.width -
dividerThickness;
rightFrame.size.height = newFrame.size.height;
rightFrame.origin.x = newFrame.origin.x + leftFrame.size.width +
dividerThickness;
[leftView setFrame:leftFrame];
[rightView setFrame:rightFrame];
[sender adjustSubviews];
[sender display];

How to: many users edit same file at the same time ?
Hello everyone ! Again me with another bizarre question So I am interested how to implement a possibility that many users can edit same file (text, XML, sheet, database entry) at the same time ? Forget the networking part for now and focus on the part of what to use for file: txt file, xml file, database ? Witch one is more appropriate ? How does that file gets saved when many people edit it at the same time ? How to implement restrictions for some users (privileges) ? To explain what I'm trying to figure out, is how collaborative editor like SubEthaEdit works (with files, file-locking, accessing, saving, etc) Thanks to all in advance.

Re: How to make app login window to look like OS X user login window ?
On 2009.04.23, at 04:08, Chris Hanson wrote: You shouldn't always show a log-in panel in your application either; Mac OS X has the Keychain for secure storage of user credentials, you should only ask the user to log in to your service if there's no stored credential or they've done something like reset their password. And instead of checking network connectivity, your application should just try to use the network and fail gracefully when it's not available. After all, it could go away between when you check and actually start using it, or while you're using it - at that point, what does checking get you? Well I was thinking this way: First window that shows when you start the app is login window because user can't use an app if he doesn't log in. And about Splash Screen: The user name and password provided in login window is checked against a remote database over network, so that is why network check is done on app launch and while that is performed I show Splash Screen. If network resources are unavailable no login window is showed but instead a window that perform certain tasks regarding the problem (if no connection - open network pref, if no database - select or create database, etc). I hope I made it a little bit clear about what I'm trying to accomplish.

How to make app login window to look like OS X user login window ?
Greetings everyone ! So the question is how to make a window that doesn't have a title bar and borders ? Actually I would like it to be just like user login window of OS X.

On 2009.04.13, at 11:15, Quincey Morris wrote:
Not exactly. Make your application delegate (let's say its class is
MyAppDelegate) separate from your window controller. So, the steps
are:
-- write a MyAppDelegate class (subclass of NSObject)
-- in IB, drag an object into MainMenu.xib, and set its class to
MyAppDelegate (that causes an instance to be created automatically
when your app starts up)
-- in IB, connect the 'delegate' outlet of the (predefined)
Application object in MainMenu.xib to the MyAppDelegate object (that
causes your MyAppDelegate object to actually *be* the application's
delegate)
-- in your MyAppDelegate class, add an instance variable
mainWindowController, of class MainWindowController
-- in your MyAppDelegate class, write an
applicationDidFinishLaunching: method something like this:
- (void) applicationDidFinishLaunching: (NSNotification *)
aNotification {
mainWindowController = [[MainWindowController alloc] init];
[mainWindowController showWindow: nil];
}
-- your MainWindowController's init method should look something
like this:
- (id) init {
self = [super initWithWindowNibName: @MainWindow];
if (!self) ...
...
return self;
}
-- in IB, set the class of File's Owner in MainWindow.xib to
MainWindowController
I may have left out something, but that's the basic idea.
It's working !
Thank you!
Tell me please should and in what cases would I keep MyAppDelegate
separate from MainWindowController and in what not, because I kinda
made it work all from one place:
#import Cocoa/Cocoa.h
@interface MainWindowController : NSObject
{
NSWindowController *mainWindowController;
}
@end
#import MainWindowController.h
@implementation MainWindowController
- (void) applicationDidFinishLaunching:(NSNotification *) aNotification
{
mainWindowController = [[NSWindowController alloc]
initWithWindowNibName:@MainWindow];
[mainWindowController showWindow:nil];
}
@end
And about delegates, so if I want to do something else now I have to
create another object in MainMenu.nib and make it a delegate of proxy
object Application again ?
There can be multiple delegations for one Application object ?
Or should I make one object that will be a delegate but will hold the
code for all other stuff ?
Could you explain this to me a little bit more ?
Thanks !

How to open two nibs at app launch ? Beginners question
My regards to all on the list My name is Mario and I am now to Cocoa and Objective-C so I have some questions which will sound trivial to those with more experience. Please don't refer me to documentations because I have read them and looked for an answer and I tried to do it according to documentations but I still can't make it. That is why I posting here. The problem is: I have MainMenu.xib with only main menu whose File's Owner is NSApplication. I want to have MainWindow.xib with only a window but that will be launched also when the application starts. Now you will ask why separate nibs ? Never mind why ! I just want it that way ! Is that wrong ? So I read the docs and it says that I need to have File's Owner for that nib that is external to that nib. I tried putting NSWindowController but I don't know where and how do I instantiate that class ? I tried creating a subclass of NSWindowController and using it for the File's Owner and according to output of NSLog everything gets allocated and initialized but window does not get showed. I starting to think that I should do something in main.m but I don't think that would be the right way. I am doing something wrong so please point me the right way.
