    <p>If your sheet is a nib/xib with an NSPanel, the call to close it is simply [panel close]; Assuming your window controller has a property for the panel, you can put the close code at the end of its row-adding IBAction. Or you could have the IBAction itself call another method if you prefer.</p> <p>If your panel is running modal, you might need to stopModal too. (That's what's needed if everything stays frozen after the panel closes; otherwise never mind.)</p> <p>Assuming hopBill, your data source, is a property of the window controller, any IBAction you write in the window controller also has access to hopBill; it can do everything you need.</p> <p>So add a single IBAction to the window controller and connect the panel's OK button to it. That ought to work.</p> <p>As for calling an IBAction from somewhere other than a control in a nib, yes, you can do that. Use a reference to the control as the sender arg, or nil if the IBAction doesn't use the sender arg.</p> <p>You could also create your panel programmatically, or use NSAlert. But it sounds like your current setup is simpler -- and therefore better. </p> <hr> <p>Take a look at this h file for an app controller: <a href="http://developer.apple.com/library/mac/#samplecode/ClockControl/Listings/AppController_h.html" rel="nofollow">Apple's ClockControl example</a></p> <p>The NSMutableArray *appointments property is the actual data source that will be used by the NSTableViewDataSource protocol methods. The IBAction "addAppointment" can access "appointments" directly: [self.appointments addObject:whatever atIndex:whatever];</p> <p>The ClockControl example could be modified to use HopBill. You would import its declarations up top: #import "HopBill.h" And then instead of the "appointments" property, it would declare HopBill *hopBill; And "addApointment" would access HopBill's mutable array (aHopBill) like this: [self.hopBill.aHopBill addObject:whatever atIndex:whatever];</p>

    1. COThanks for your answer. The NSPanel runs as modal and is a different object than the hopBill my datasource. That's why I haven't got access to hopBill. I need to perform two action on two different objects, adding a record to my datasource and closing the window. Or is it best practice to make one object out of the datasource object and the modal window object?

    2. CORight, the NSPanel has to be a different object from the data source. Both the panel and HopBill would normally be properties of your window controller. I've added to my answer an example that might make the structure more clear. You might also want to consult an Objective-C or Cocoa programming book for some complete tutorials. It's hard to understand this stuff just by discussion.

    3. COThanks for your answer. I can't seem to get it to work. I added #import HopBill.h to HopBillSheetController.h. And inserted the code you mentioned in HopBillSheetController.m. But on Build I get an error on the [self.hopBill.aHopBill] line stating "Request for member 'hopBill' in something not a structure or union". Maybe I'm doing something completely wrong, that why I uploaded the source to: http://kloran.home.xs4all.nl/iBrouwsrc.zip. I've got the books Objective-C for Dummies and Cocoa Programming for Mac OS X for Dummies.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
