WPF - AvalonDock - Kapanış Belgesi

Question

WPF projesinde MVVM ile AvalonDock kullanıyorum.

"X" 'ye ("Sekme Kapat") bastığımda, belgem kapanıyor, ancak bellekte kalıyor. Görünüşe göre sadece gizli. Model.Documents koleksiyonumdan kaldırılmadı.

DockingManager_DocumentClosing ekler ve belgesini koleksiyondan kaldırmaya çalışırsanız, aşağıdaki yöntemde bir Özel Durum alırsınız, çünkü parentAsContainer boştur.

/// <summary> 
/// Close the content 
/// </summary> 
/// <remarks>Please note that usually the anchorable is only hidden (not closed). By default when user click the X button it only hides the content.</remarks> 
public void Close() 
{ 
    var root = Root; 
    var parentAsContainer = Parent as ILayoutContainer; 
    parentAsContainer.RemoveChild(this); 
    if (root != null) 
     root.CollectGarbage(); 
    OnClosed(); 
} 

herkes ben onun Close düğmesine vurduğunda sonunda bertaraf edilmesi edilebilmesi için benim Model.Documents çıkarılabilir AvalonDock belgeyi yönetmek nasıl biliyor mu? Başvuru için

:

Answer 1

Aslında kabul edilemez bir geçici çözüm bulmak: Bu AvalonDock benim XAML olduğunu. Gerçekten bükülmüş.

Sadece bunu referans olarak verdim. Bunu yapmanın temiz bir yolu olmalı.

// ************************************************************************ 
    private void DockingManager_DocumentClosing(object sender, Xceed.Wpf.AvalonDock.DocumentClosingEventArgs e) 
    { 
     e.Document.CanClose = false; 

     DocumentModel documentModel = e.Document.Content as DocumentModel; 
     if (documentModel != null) 
     { 
      Dispatcher.BeginInvoke(new Action(() => this.Model.DocumentItems.Remove(documentModel)), DispatcherPriority.Background); 
     } 
    } 

Answer 2

IsVisibleChanged için kayıt. CanClose="False" veya CanFloat="False":

void layoutFPR_Hidden(object sender, EventArgs e) 
{ 
    LayoutAnchorable window = (LayoutAnchorable)sender; 
    YourClass content = window.Content as YourClass; 

    // Close the object 
    content = null; 
    ((LayoutAnchorable)sender).Close(); 

} 

Answer 3

Ben LayoutDocument veya LayoutAnchorablePane, bu ayarı hem uygulayarak çalışır bulduk.

Kapat düğmesini kaldırır.

<avalonDock:LayoutDocument Title="Board" 
          ContentId="Board" 
          CanClose="False" 
          CanFloat="False"> 
</avalonDock:LayoutDocument>
