Silverlight 中的拉伸 TabItem 标头

发布于 2024-11-09 18:33:24 字数 230 浏览 1 评论 0原文

如何使选项卡项标题在 Silverlight 中拉伸到选项卡控件的宽度？如果重要的话，我总是有固定数量的选项卡。

我只找到了 WPF 示例，使用 IMultiValueConverter 在这里。

这是一个示例

这是非常简单的任务..您所要做的就是创建默认模板的副本并替换 System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelTop" 和 te:StockPanel x:Name="TabPanelTop" 基本上覆盖了布局逻辑。

public class StockPanel: System.Windows.Controls.Primitives.TabPanel
{
    protected override Size MeasureOverride(Size availableSize)
    {
        var cc = Children.Count;

        foreach (var child in Children)
        {
            child.Measure(new Size(availableSize.Width / cc, availableSize.Height));
        }

        return base.MeasureOverride(availableSize);
    }

    protected override Size ArrangeOverride(Size finalSize)
    {
        var cc = Children.Count;
        var i = 0;

        foreach (var child in Children)
        {
            child.Arrange(new Rect((finalSize.Width / cc) * i, 0, finalSize.Width / cc, finalSize.Height));
            i++;
        }

        return new Size(finalSize.Width, finalSize.Height);
    }
}

PS：这不是完美的代码示例，但我认为这足以让您理解如何扩展 TabControl

Here an example

It's preaty simple task.. all you have to do is to create Copy of default template and replace System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelTop" with te:StockPanel x:Name="TabPanelTop" which basicly override layout logic..

public class StockPanel: System.Windows.Controls.Primitives.TabPanel
{
    protected override Size MeasureOverride(Size availableSize)
    {
        var cc = Children.Count;

        foreach (var child in Children)
        {
            child.Measure(new Size(availableSize.Width / cc, availableSize.Height));
        }

        return base.MeasureOverride(availableSize);
    }

    protected override Size ArrangeOverride(Size finalSize)
    {
        var cc = Children.Count;
        var i = 0;

        foreach (var child in Children)
        {
            child.Arrange(new Rect((finalSize.Width / cc) * i, 0, finalSize.Width / cc, finalSize.Height));
            i++;
        }

        return new Size(finalSize.Width, finalSize.Height);
    }
}

PS: it's not perfect code sample, but i think it's enouth for you to understand how to extend TabControl
