問題描述

我正面臨這樣的問題，我覺得很難克服.在 WinForms 中，我得到了一個(gè)帶有 n 個(gè) TabPages 的 TabControl.我想擴(kuò)展 Ctrl+Tab/Ctrl+Shift+Tab 切換.所以我寫了一些代碼，只要焦點(diǎn)在 TabControl 或 Form 上就可以正常工作.當(dāng)應(yīng)用程序焦點(diǎn)位于 TabPage 內(nèi)部時(shí)(例如，位于 TabPage 內(nèi)部的按鈕上)，按下 Ctrl+Tab 時(shí)，我的代碼將被忽略，并且 TabControl 會(huì)自行跳到 TabPage(避免我的代碼).

Iam facing such problem, which I find hard to overcome. In WinForms I got a TabControl with n TabPages. I want to extend the Ctrl+Tab / Ctrl+Shift+Tab switching. so I wrote some code which works fine as long as the focus is on TabControl or on the Form. When application focus is INSIDE of TabPage (for example on a button which is placed inside of TabPage), while pressing Ctrl+Tab, my code is ignored and TabControl skips to TabPage on his own (avoiding my code).

有人知道嗎?

推薦答案

您需要從 TabControl 派生并覆蓋 ProcessCmdKey，虛擬方法才能覆蓋 Ctrl-Tab 行為.

You need to derive from TabControl and override ProcessCmdKey, virtual method in order to override the Ctrl-Tab behavior.

例子:

public class ExtendedTabControl: TabControl
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == (Keys.Control | Keys.Tab))
        {
            // Write custom logic here
            return true;
        }
        if (keyData == (Keys.Control | Keys.Shift | Keys.Tab))
        {
            // Write custom logic here, for backward switching
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}
