macOS custom cells in tableview

[medasmx]

I have been working on this custom cells for table view for a while, through various posts. The code below works and does the following...creates a 3x3 table view of gray cells. There is a pop-up button that will print text ("jimmy" here), depending on which column is selected (1 through 3). Appreciate prior input of Kainjow.

Here is the code for the custom cells...

#import "MyCell.h"

@implementation MyCell

-(void)prepareAttributes
{
	attributes=[[NSMutableDictionary alloc]init];
	[attributes setObject:[NSFont fontWithName:@"Helvetica" size:20] forKey:NSFontAttributeName];
	[attributes setObject:[NSColor blackColor] forKey:NSForegroundColorAttributeName];
}

- (id)initWithFrame:(NSRect)frameRect {
    self = [super initWithFrame:frameRect];

    if (!self) return nil;
	[self prepareAttributes];
	string=@"Jimmy";
    return self;
}

-(void)dealloc
{
	[string release];
	[super dealloc];
}

-(NSString*)string
{
	return string;
}

-(void)setString:(NSString*)c
{
	c=[c copy];
	[string release];
	string=c;
}

-(void)drawStringCenteredIn:(NSRect)cellFrame
{
	NSPoint textPoint;
		
	textPoint.x = cellFrame.origin.x + 5;
	textPoint.y = cellFrame.origin.y;
	
	[string drawAtPoint:textPoint withAttributes:attributes];
}


-(void)drawWithFrame:(NSRect)cellFrame inView:(NSView*)controlView
{
	[[NSColor grayColor]set];
	NSRectFill(NSInsetRect(cellFrame,4,4));

	[self drawStringCenteredIn:cellFrame];
}

@end

Here is the code for the appcontroller...

#import "AppController.h"
#import "MyCell.h"

@implementation AppController

-(void)awakeFromNib
{
	data=[[NSArray alloc]initWithObjects:@"1",@"2",@"3",nil];
	myCell=[[[MyCell alloc]init]autorelease];
	NSTableColumn*column=[tv tableColumnWithIdentifier:@"columnOne"];
	[column setDataCell:myCell];
	NSTableColumn*column2=[tv tableColumnWithIdentifier:@"columnTwo"];
	[column2 setDataCell:myCell];
	NSTableColumn*column3=[tv tableColumnWithIdentifier:@"columnThree"];
	[column3 setDataCell:myCell];
	[tv setRowHeight:100];
}

-(int)numberOfRowsInTableView:(NSTableView *)tv
{
	return [data count];
}

-(id)tableView:(NSTableView *)tv objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row 
{
	return [data objectAtIndex:row];
}

-(IBAction)asmbutton1:(id)sender;
{
	NSString*buttonString=[(NSPopUpButton*)sender titleOfSelectedItem];
	NSString*mySecondString=@"jimmy";
	NSString*myThirdString=@"";
	mySecondCell=[[[MyCell alloc]init]autorelease];
	myThirdCell=[[[MyCell alloc]init]autorelease];
	[mySecondCell setString:mySecondString];
	[myThirdCell setString:myThirdString];
	
	NSTableColumn*column=[tv tableColumnWithIdentifier:@"columnOne"];
	NSTableColumn*column2=[tv tableColumnWithIdentifier:@"columnTwo"];
	NSTableColumn*column3=[tv tableColumnWithIdentifier:@"columnThree"];
	
	if ([buttonString isEqualToString:@"1"]) {
	[column setDataCell:mySecondCell];	
	[column2 setDataCell:myThirdCell];
	[column3 setDataCell:myThirdCell];}
	
	else if ([buttonString isEqualToString:@"2"]) {
	[column2 setDataCell:mySecondCell];
	[column setDataCell:myThirdCell];
	[column3 setDataCell:myThirdCell];}
	
	else {[column3 setDataCell:mySecondCell];	
	[column setDataCell:myThirdCell];
	[column2 setDataCell:myThirdCell];}
}

@end

What I really want to do is to have a pop-up 1-9 and be able to put the text in one specific cell, not just the whole column. I read some about dataCellForRow:, but haven't figured it out yet. Any help is appreciated. Thanks
