wpf - Fluent Ribbon：指定上下文选项卡组的位置？

Question

在 Fluent Ribbon Control Suite 中，有没有办法让上下文选项卡组首先显示而不是最后显示？我使用的是旧版本，前三个选项卡项有一个上下文选项卡组，另外两个没有组。下载并构建了最新的源码；组中的选项卡现在位于右端。我希望它们以与我在 xaml 中指定的顺序相同的顺序显示。我没有看到任何明显的属性可以让我指定顺序。

由于没有人对此有答案，而我刚刚获得了 Tumbleweed 徽章 :)，我决定发布我的解决方案，即修改 Fluent Ribbon Control Suite 代码。我ArrangeOverride在RibbonTabsContainer课堂上修改。这导致分组选项卡在不属于组的选项卡之前呈现：

        /// <summary>
        /// Positions child elements and determines
        /// a size for the control
        /// </summary>
        /// <param name="finalSize">The final area within the parent 
        /// that this element should use to arrange 
        /// itself and its children</param>
        /// <returns>The actual size used</returns>
        protected override Size ArrangeOverride(Size finalSize)
        {
            var finalRect = new Rect(finalSize)
                                {
                                    X = -this.HorizontalOffset
                                };

            var orderedChildren = this.InternalChildren.OfType<RibbonTabItem>()
                                      .OrderByDescending(x => x.Group != null); // <==== originally .OrderBy

            foreach (var item in orderedChildren)
            {
                finalRect.Width = item.DesiredSize.Width;
                finalRect.Height = Math.Max(finalSize.Height, item.DesiredSize.Height);
                item.Arrange(finalRect);
                finalRect.X += item.DesiredSize.Width;
            }

            var ribbonTabItemsWithGroups = this.InternalChildren.OfType<RibbonTabItem>()
                                               .Where(item => item.Group != null);

            var ribbonTitleBar = ribbonTabItemsWithGroups.Select(ribbonTabItemsWithGroup => ribbonTabItemsWithGroup.Group.Parent)
                                                         .OfType<RibbonTitleBar>()
                                                         .FirstOrDefault();

            if (ribbonTitleBar != null)
            {
                ribbonTitleBar.InvalidateMeasure();
            }

            return finalSize;
        }
