c# - RibbonControlsLibrary - 如何禁用最小化？

Question

如何从 RibbonControlsLibrary 禁用功能区控件的最小化？

Answer 1

以下为我禁用了双击选项卡标题和上下文菜单上的“最小化功能区”：

public class ExRibbon : Ribbon
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();

        IsMinimizedProperty.OverrideMetadata(typeof(ExRibbon),
                new FrameworkPropertyMetadata(false, (o, e) => { }, (o, e) => false));

        Type ownerType = typeof(ExRibbon);
        CommandManager.RegisterClassCommandBinding(ownerType,
            new CommandBinding(RibbonCommands.MinimizeRibbonCommand, null, MinimizeRibbonCanExecute));
    }

    private static void MinimizeRibbonCanExecute(object sender, CanExecuteRoutedEventArgs args)
    {
        args.CanExecute = false;
        args.Handled = true;
    }
}

Answer 2

public class ExRibbon : Ribbon
{
    public override void OnApplyTemplate()
    {
         base.OnApplyTemplate();

         if (!IsMinimizable)
         {
              IsMinimizedProperty.OverrideMetadata(typeof(ExRibbon), 
                   new FrameworkPropertyMetadata(false, (o, e) => { }, (o,e) => false));
         }
    }
    public bool IsMinimizable { get; set; }
}

Answer 3

最小化控件且无法禁用的唯一方法是双击 Tab 标题，实际上三次单击或超过 2 次单击也会使控件最小化，这就是我的第一个想法失败的原因（我试图取消双击事件，但控件在第三次单击时最小化）。

TabHeaderItemsControl所以这个解决方案不是太漂亮但它工作正常，当在（这是保存选项卡的控件） 上检测到超过两次点击时，控件被最大化

public class MinimizableRibbon : Ribbon
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();

        RibbonTabHeaderItemsControl tabItems = this.FindName("TabHeaderItemsControl") as RibbonTabHeaderItemsControl;

        int lastClickTime = 0;
        if (tabItems != null)
            tabItems.PreviewMouseDown += (_, e) =>
                {
                    // A continuous click was made (>= 2 clicks minimizes the control)
                    if (Environment.TickCount - lastClickTime < 300)
                        // here the control should be minimized
                        if (!IsMinimizable)
                            IsMinimized = false;

                    lastClickTime=Environment.TickCount;
                };
    }

    public bool IsMinimizable { get; set; }
}
