我可以自定义AvalonDock上下文菜单吗?

本文关键字：菜单 上下文 自定义 AvalonDock 我可以 | 更新日期: 2023-09-27 18:12:49

我在一个项目中使用AvalonDock来利用工具窗口。

我没有任何需要的选项卡文档，并希望禁用"Dock作为选项卡文档"上下文菜单项，当我右键单击工具窗口标题栏。这可能吗?

谢谢

我可以自定义AvalonDock上下文菜单吗?

我认为这是一个简单的属性设置。我使用codeplex 76560的最新源代码。

你可以把DockableStyle属性改成你想要的样式:

<ad:SampleDockableContent DockableStyle="DockableToBorders"
                    x:Name="DockingManagerPropertiesHost"
                    Title="Only dock to borders">
</ad:SampleDockableContent>

，并且可以重写此方法以禁用内容菜单:

public partial class SampleDockableContent : DockableContent
{
  public SampleDockableContent() {
    this.InitializeComponent();
    this.DataContext = this;
  }
  protected override bool CanExecuteCommand(ICommand command) {
    if (command == DockableContentCommands.ShowAsDocument) {
      if (this.DockableStyle == DockableStyle.DockableToBorders) {
        return false;
      }
      if (this.State == DockableContentState.Document) {
        return false;
      }
    }
    return base.CanExecuteCommand(command);
  }
}

这里是标志枚举:

/// <summary>
/// Defines how a dockable content can be dragged over a docking manager
/// </summary>
/// <remarks>This style can be composed with the 'or' operator.</remarks>
public enum DockableStyle : uint
{ 
    /// <summary>
    /// Content is not dockable at all
    /// </summary>
    None = 0x0000,
    /// <summary>
    /// Dockable as document
    /// </summary>
    Document    = 0x0001,
    /// <summary>
    /// Dockable to the left border of <see cref="DockingManager"/>
    /// </summary>
    LeftBorder  = 0x0002,
    /// <summary>
    /// Dockable to the right border of <see cref="DockingManager"/>
    /// </summary>
    RightBorder = 0x0004,
    /// <summary>
    /// Dockable to the top border of <see cref="DockingManager"/>
    /// </summary>
    TopBorder   = 0x0008,
    /// <summary>
    /// Dockable to the bottom border of <see cref="DockingManager"/>
    /// </summary>
    BottomBorder= 0x0010,
    /// <summary>
    /// A <see cref="DockableContent"/> with this style can be hosted in a <see cref="FloatingWindow"/>
    /// </summary>
    Floating = 0x0020,
    /// <summary>

    /// </summary>
    /// <remarks>This style is not compatible with <see cref="DockableStyle.Document"/> style</remarks>
    Single = 0x0040,
    /// <summary>
    /// A <see cref="DockableContet"/> with this style can be autohidden.
    /// </summary>
    AutoHide = 0x0080,
    /// <summary>
    /// Dockable only to a border of a <see cref="DockingManager"/>
    /// </summary>
    DockableToBorders = LeftBorder | RightBorder | TopBorder | BottomBorder | AutoHide,
    /// <summary>
    /// Dockable to a border of a <see cref="DockingManager"/> and into a <see cref="DocumentPane"/>
    /// </summary>
    Dockable = DockableToBorders | Document | Floating,
    /// <summary>
    /// Dockable to a border of a <see cref="DockingManager"/> and into a <see cref="DocumentPane"/> but not in autohidden mode (WinForms controls)
    /// </summary>
    DockableButNotAutoHidden = Dockable & ~AutoHide
}
