Describe NSTextFieldCellSubclassandfontproblem here.

Im developing a font managment software in cocoa, and im having problems with the preview of the fonts.

For the preview Im using a NSTableView, with a subclass of NSTextFieldCell. In this subclass I draw the name of the font and a text example with the font.

The problem is after I preview the font in a cell, i can�t deactivate it. It seems like the NSFont object used in the cell is not released and dont allow to deactivate the font.

The NSTextFieldCell Subclass code:

@implementation TextPreviewCell

• (void)dealloc { NSLog(@”deallocing CELL”); [datosColumna release]; datosColumna = nil; [super dealloc]; }//end method

• (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {

    NSRect	rectanguloCabecera;
    NSDivideRect(cellFrame, &rectanguloCabecera, &cellFrame, 14, NSMinYEdge);
  	
    if (sStripeColor == nil) sStripeColor = [[NSColor colorWithCalibratedRed:STRIPE_RED green:STRIPE_GREEN blue:STRIPE_BLUE alpha:1.0] retain];
    [sStripeColor set];
    rectanguloCabecera.size.width = (rectanguloCabecera.size.width + 8);
    rectanguloCabecera.origin.x = (rectanguloCabecera.origin.x - 1);
    rectanguloCabecera.origin.y = (rectanguloCabecera.origin.y - 2);
   		NSRectFill(rectanguloCabecera);
  	
    NSPoint p;
    p.x = rectanguloCabecera.origin.x + 3;
    p.y = rectanguloCabecera.origin.y + 1;
  	
    int columna = [controlView rowAtPoint:p];
    NSString *nombreFuente = controlView dataSource] getDataRow:columna];
  	
    [[NSFont *fuenteCabecera = [[NSFont fontWithName:@"LucidaGrande" size:10] autorelease];
    NSMutableDictionary *estilo = [NSMutableDictionary dictionary]; [estilo setObject:fuenteCabecera forKey:NSFontAttributeName];
    [nombreFuente drawAtPoint:p withAttributes:estilo];
  	
    if (tamanoFuente == 0) [self setTamanoFuente:8];
    if (textoCelda == nil) [self setTexto:@"sin asignar"];
  	
    NSFont *fuente = [[NSFont fontWithName:nombreFuente size:tamanoFuente] autorelease];
  	
    [self setFuente:fuente];
    [self setFont:font];
    [self setStringValue:textoCelda];
    [self setLineBreakMode:NSLineBreakByTruncatingTail];
    [self setWraps:NO];
  
    [super drawWithFrame:cellFrame inView:controlView];
  

}

For activating the font Im using:

err = ATSFontActivateFromFileSpecification(&fspec, kATSFontContextGlobal, kATSFontFormatUnspecified, NULL, kATSOptionFlagsDefault, &id_fuente);

And for deactivating:

ATSFontDeactivate(id_fuente, NULL, kATSOptionFlagsDefault);

If I activate the font without preview in the table, works fine, activating and deactivating the font.

I note that if I put a NSLog in the dealloc method of my NSTextFieldCell subclass, it sends the log when i click in the row or when i move the scrolls, but it not log when I reload data in the data source of the NSTableView, but the rows are deleted and the new data is displayed. �are those cells deallocated?.

Sorry for my English and thanks.
