改变的TabControl的SelectedTab鼠标悬停 [英] Change SelectedTab of TabControl on MouseOver

问题描述

我有一个Windows窗体项目以的TabControl 。

I have a Windows Forms project with a TabControl.

有谁知道如何修改 SelectedTab 当你将鼠标悬停在它的指针？

Does anyone know how to change the SelectedTab when you hover over it with the pointer?

推荐答案

您可以使用的TabControl的MouseMove事件检测鼠标是否存在任何选项卡，然后可以选择它：

You can use TabControl's MouseMove event to detect whether your mouse is present on any tab and then can select it:

private void tabControl1_MouseMove(object sender, MouseEventArgs e)
{
    Rectangle mouseRect = new Rectangle(e.X, e.Y, 1, 1);
    for (int i = 0; i < tabControl1.TabCount; i++)
    {
        if (tabControl1.GetTabRect(i).IntersectsWith(mouseRect))
        {
            tabControl1.SelectedIndex = i;
            break;
        }
    }
}
