RibbonControlsLibrary -如何禁用最小化？

Question

如何在RibbonControlsLibrary中禁用最小化功能区控件？

Answer 1

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; }
}

下面的代码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”功能：

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;
    }
}

最小化控件并且不能被禁用的唯一方法是双击Tab标题，事实上，三次单击或超过两次单击也会最小化控件，这就是为什么我的第一个想法失败了(我试图取消双击事件，但控件在第三次单击时最小化)。

因此，这个解决方案不是太复杂，但它工作得很好，当在TabHeaderItemsControl (这是保存选项卡的控件)上检测到两次以上的单击时，该控件将最大化

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; }
}
