推荐答案

本地的Windows标签控件允许覆盖默认的最小宽度标签。可悲的是这种能力不是在TabControl的包装类暴露出来。这是可以解决的，但。添加一个新类到您的项目并粘贴如下所示的代码。编译。 。从工具箱到窗体顶部的新的控制

The native Windows tab control allows overriding the default minimum tab width. Sadly that capability is not exposed in the TabControl wrapper class. That's fixable though. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.

using System;
using System.Windows.Forms;

class MyTabControl : TabControl {
    protected override void OnHandleCreated(EventArgs e) {
        base.OnHandleCreated(e);
        // Send TCM_SETMINTABWIDTH
        SendMessage(this.Handle, 0x1300 + 49, IntPtr.Zero, (IntPtr)10);
    }
    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);
}
