I'm building a submenu on the fly that will contain the names of the  
current uucp-connected systems:  Here is the code:


systemMenu = [[Menu alloc] init];	
subCell = [mainMenu findCellWithTag:28];
[mainMenu setSubmenu:systemMenu forItem:subCell];
	
pp = popen("/usr/bin/uuname","r");
	
while(fgets(instr,sizeof(instr),pp) != NULL) {
	instr[strlen(instr) - 1] = '\0';
	strcat(instr,"...");
	newCell = [systemMenu addItem:instr action:@selector(newMonitor:)
		keyEquivalent:0];
	[newCell setTarget:self];
}
	
pclose(pp);



The newMonitor is defined as - newMonitor:sender.  The menu builds  
beautifully but when testing and choosing one of my new menu items,  
instead of getting the id of the menuCell in newMonitor, I get the id of  
the Matrix of menuCells.  

How can I set this up so that I can identify which cell sent the message?   
Is this the best way to approach the problem?

Thanks,

tjb

Following up my own post, Paul Kim (pkim@delft.berkeley.edu) gave me the  
answer I needed.  In newMonitor, I just needed to call 
[sender selectedCell] to get the id of the chosen cell.

Thanks,

NeXT's User Interface Guidelines people STRONGLY DISCOURAGE this.
[Think about what happens when you have a large number of items.]
