我有以下 ViewModel,我正在使用 Caliburn Micro。IWindowManager 实例已正确解析,并且所有代码都可以正常工作。如 TODO 注释所示,我需要获取对当前窗口的引用,以便切换 AlwaysOnTop 属性。我怎样才能做到这一点?
namespace CaliburnWizardPlay
{
[Export(typeof(DropWindowViewModel))]
public class DropWindowViewModel : PropertyChangedBase, IHaveDisplayName
{
private readonly IWindowManager windowManager;
[ImportingConstructor]
public DropWindowViewModel(IWindowManager windowManager)
{
this.windowManager = windowManager;
}
public string DisplayName
{
get { return "Main Window"; }
set { }
}
public bool AlwaysOnTop
{
get { return Settings.Default.DropWindowAlwaysOnTop; }
set
{
Settings.Default.DropWindowAlwaysOnTop = value;
Settings.Default.Save();
NotifyOfPropertyChange(() => AlwaysOnTop);
//todo: toggle the AOT attribute of the window
}
}
public void FileDropped(DragEventArgs eventArgs)
{
if (eventArgs.Data.GetDataPresent(DataFormats.FileDrop))
{
string[] droppedFilePaths = eventArgs.Data.GetData(DataFormats.FileDrop, true) as string[];
foreach (string path in droppedFilePaths)
{
MessageBox.Show(path);
}
windowManager.ShowWindow(new WizardViewModel());
}
}
}
}
