[Mono-osx] Dynamically add User Control (SubView) defined in the Nib

[Tomas Trescak]

Hi

I am trying following code:

SubView sb = new SubView (box.Handle); // subview is the monomac code 
generated to my nib
sb.SetFrameOrigin (new PointF (0, 100));
sb.SetFrameSize (new SizeF(200, 200));
box.AddSubview(sb); // box the the NSView contorl type box

Doing this the whole thing crashes ;(

Tomas

PS: Here is the remaining code

public partial class SubView : MonoMac.AppKit.NSView
{
#region Constructors

// Called when created from unmanaged code
public SubView (IntPtr handle) : base (handle)
{
Initialize ();
}

// Called when created directly from a XIB file
[Export ("initWithCoder:")]
public SubView (NSCoder coder) : base (coder)
{
Initialize ();
}

// Shared initialization code
void Initialize ()
{
}

#endregion
}


public partial class MainWindowController : 
MonoMac.AppKit.NSWindowController
{
#region Constructors

// Called when created from unmanaged code
IntPtr hndl;

public MainWindowController (IntPtr handle) : base (handle)
{
Initialize ();
hndl = handle;
}

// Called when created directly from a XIB file
[Export ("initWithCoder:")]
public MainWindowController (NSCoder coder) : base (coder)
{
Initialize ();
}

// Call to load from the XIB/NIB file
public MainWindowController () : base ("MainWindow")
{
Initialize ();
}

// Shared initialization code
void Initialize ()
{
}

#endregion

//strongly typed window accessor
public new MainWindow Window {
get {
return (MainWindow)base.Window;
}
}

int count = 0;

partial void ClickButton (NSObject sender)
{
label.StringValue = string.Format ("Button clicked {0} times.", ++count);

SubView sb = new SubView (box.Handle);
sb.SetFrameOrigin (new PointF (0, 100));
sb.SetFrameSize (new SizeF(200, 200));
box.AddSubview(sb);
}
}
