禁止在TabControl的默认快捷键 [英] Disable default shortcuts on a TabControl

问题描述

<大骨节病>控制 + <大骨节病>上一页 / <大骨节病>下页和<大骨节病>控制 + <大骨节病>标签是默认的快捷键为TabControl的。他们帮助在相邻标签之间移动。我想<大骨节病>控制 + <大骨节病> pageX属性行为只为外标签（TAB1，TAB2）携手<大骨节病>控制 + <大骨节病>标签为内标签（TAB3，TAB4）时，我的重点是在控制（文本框在这里）的行为。对于这一点，我需要禁用默认行为。是否有某种方式来做到这一点？

Ctrl + PageUp/PageDown and Ctrl + Tab are default shortcuts for the TabControl. They help in moving between adjacent tabs. I would like Ctrl + PageX behaviour to work only for the outer tabs (tab1, tab2) and Ctrl + Tab behaviour for the inner tabs (tab3, tab4) when my focus is in the control (textbox here). For this, I need to disable the default behaviour. Is there some way to do this?

我看着ProcessDialogKey和IsInputKey，但他们似乎只与单个KEYDATA工作。修饰符不处理。

I looked at ProcessDialogKey and IsInputKey, but they seem to work only with single keydata. Modifiers are not handled.

推荐答案

的TabControl 有着不同寻常的键盘快捷方式处理，它们被反射到的onkeydown（ ）方法。这样做是为了避免干扰键盘操作的控制选项卡页面上。

TabControl has unusual keyboard shortcut processing, they are reflected to the OnKeyDown() method. This was done to avoid it disturbing the keyboard handling for the controls on a tab page.

你必须要覆盖的方法。添加一个新类到您的项目并粘贴下面所示的code。编译。从工具箱顶新控制到你的表格。

You'll have to override the method. 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 OnKeyDown(KeyEventArgs e) {
    if (e.KeyData == (Keys.Tab | Keys.Control) ||
        e.KeyData == (Keys.PageDown | Keys.Control)) {
      // Don't allow tabbing beyond last page
      if (this.SelectedIndex == this.TabCount - 1) return;
    }
    base.OnKeyDown(e);
  }
}
