I am creating a tableview and using NSDictionaryController
.
case.dict
file
I am using this code:
@interface MyClass : NSWindowController{
IBOutlet NSTableView *tableView;
IBOutlet NSDictionaryController *dictController;
IBOutlet NSArrayController *peopleList;
NSDictionary *currentPerson;
}
@property (retain) NSDictionary *currentPerson;
MyClass.m file
- (void)windowDidLoad
{
[super windowDidLoad];
NSBundle *bundle = [NSBundle mainBundle];
NSString *path = [bundle pathForResource: @"case" ofType: @"dict"];
NSArray *listFromFile = [NSArray arrayWithContentsOfFile: path];
[tableView setSortDescriptors:[NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"icon" ascending:YES] autorelease]]];
[peopleList addObserver:self forKeyPath:@"selectionIndexes" options:NSKeyValueObservingOptionNew context:nil];
if (listFromFile != nil)
{
[peopleList addObjects:listFromFile];
}
[peopleList setSelectionIndex:0];
[dictController bind:NSContentDictionaryBinding toObject:self withKeyPath:@"currentPerson" options:nil];
}
It works fine and table gives me image names which are stored in case.dict
file at index 0(ZERO)
.
EDIT : If i want to use something like
if (listFromFile != nil)
{
[peopleList addObjects:[NSImage ImageNAmed:listFromFile];
}
then what should i do?
Thanks in advance..!!

Anyone please help me in this.
Generally it works like this - you have to drag NSImageCell from Library on to table column, in which you want to show image, and bind its value property to an image attribute of your controller object.
Hope this helps !
