Ciao Sto cercando di utilizzare un NSPopUpButtonCell all'interno di NSTableView. Fondamentalmente quando si seleziona un elemento nel pop up lo voglio visualizzato nella colonna/riga della vista tabella. Quando viene premuto un elemento nella cella popup, lo memorizzo all'interno dell'origine dati utilizzando "tableView: setObject: forTableColumn: row", quindi quando la tabella richiede i dati che recupero e imposta lo stato della cella popup in "tableView: objectValueForTableColumn: riga:". Si prega di trovare il mio codice allegato. Sono completamente bloccato in questo momento. Spero che qualcuno possa dare un senso a questo. Grazie in anticipo.Utilizzo di NSPopUpButtonCell con NSTableView
questo è all'interno del regolatore:
//Create the table columns
NSTableColumn *nameColumn = [[NSTableColumn alloc] initWithIdentifier:LXDetailItemName];
NSTableColumn *dataTypeColumn = [[NSTableColumn alloc] initWithIdentifier:LXDetailItemDataType];
NSTableColumn *deviceColumn = [[NSTableColumn alloc] initWithIdentifier:LXDetailItemDevice];
//Data type column drop down
NSPopUpButtonCell *dataTypeDropDownCell = [[NSPopUpButtonCell alloc] initTextCell:@"" pullsDown:YES];
[dataTypeDropDownCell setBordered:NO];
[dataTypeDropDownCell setEditable:YES];
NSArray *dataTypeNames = [NSArray arrayWithObjects:@"NULL", @"String", @"Money", @"Date", @"Int", nil];
[dataTypeDropDownCell addItemsWithTitles:dataTypeNames];
[dataTypeColumn setDataCell:dataTypeDropDownCell];
//Add the columns to the table
[tableView addTableColumn:nameColumn];
[tableView addTableColumn:dataTypeColumn];
[tableView addTableColumn:deviceColumn];
enter code here
Questo è all'interno della classe origine dati/delegato.
