标签页页眉位置 [英] Tab Page Header Location

问题描述

我的表单中有一个Tab控件，我想要实现的一种简单方法是获取Tab页面页眉的确切位置.

I have a Tab Control in my Form and what I want to achieve is a simple way to get the exact location the Tab Page Header.

我已经搜索了，但是什么也没找到.有什么想法吗?

I've searched around, but I haven't found anything. Any ideas?

推荐答案

这将使 Tab 控件 blink 稍微变一点，但它将返回边界矩形的列表页面的标题.

This will make the Tab control blink a little but it will return a list of bounding Rectangles for the pages' headers..

SortedDictionary<int, Rectangle> GetTabBounds(TabControl tab)
{
    SortedDictionary<int, Rectangle> bounds = new SortedDictionary<int, Rectangle>();
    TabDrawMode tdm = tab.DrawMode;
    tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed;
    DrawItemEventHandler mit = (sl, el) => bounds.Add(el.Index, el.Bounds);
    tab.DrawItem += mit;
    tab.Refresh();
    tab.DrawItem -= mit;
    tab.DrawMode = tdm;
    tab.Invalidate();
    return bounds;
}

对于不太准确的结果，您可能只想根据页面索引和标签项的大小来计算它们.至少，如果您的页面全部位于同一行中.

For a less exact result you may simply want to calculate them from the page index and tab item size..at least if your pages are all in one row.
