[Mono-osx] NSPathControl and NSOpenPanel

Hi All,

Sorry if this is a double post. But Im not sure if my original got up here. I think its because my email wasn't setup correctly *facepalm*

Just trying to get my head around how to do mono and Objc. Loving it so far. 

The problem i've come across is that I have an application with NSPathControl in it.

When I select choose form there it pops up an NSOpenPanel. In objc, you hook up a delegate somehow and you can pass in an NSOpenPanel to NSPathControl to modify how the NSOpenPanel looks. In my case I would like a create folder button in it.

I kinda understand the theory (although I'm still pretty hazy on these delegate methods. I probably incorrectly think of them as function pointers), but I have no idea on how to do the syntax at this point (either in objc or mono). Any help with explaining exactly how to do this would be great.

this is my AppDelegate.cs file

// This file has been generated automatically by MonoDevelop to store outlets and
// actions made in the Xcode designer. If it is removed, they will be lost.
// Manual changes to this file may not be handled correctly.
using MonoMac.Foundation;
using System.Threading;

namespace TontoCopy
[Register ("AppDelegate")]
partial class AppDelegate
MonoMac.AppKit.NSPathControl sourceDirectory { get; set; }

MonoMac.AppKit.NSPathControl destinationDirectory { get; set; }

MonoMac.AppKit.NSProgressIndicator progressIndicator { get; set; }

MonoMac.AppKit.NSWindow window { get; set; }

[Action ("copy:")]
void copy (MonoMac.Foundation.NSObject sender){

progressIndicator.DoubleValue = 0.0;

TontoCopy.FileList file_list = new TontoCopy.FileList(sourceDirectory.Url.Path, destinationDirectory.Url.Path, progressIndicator);

progressIndicator.MaxValue = file_list.totalFileSize;

Thread copyThread = new Thread(file_list.copy);


Any help would be great!
