CEdit(Ctrl + X，C，V，Z，A)(剪贴板功能) [英] CEdit (Ctrl + X, C, V, Z, A) (Clipboard functions)

问题描述

从CEdit类进行子类化时，默认剪贴板功能(Ctrl + X，C，V，Z，A)(使用键盘输入& 不是上下文菜单)不会起作用.

如何在基于CDialog的应用和所以对于SDI或MDI应用程序上的CFormView！
请帮助我

When subclassing from a CEdit class, the default clipboard functions (Ctrl + X, C, V, Z, A) (Using the keyboard input & not the context menu) wont work.

How to make it possible in both CDialog based apps & so for CFormView on SDI or MDI apps !?

Help me please

推荐答案

BOOL CEditEx::PreTranslateMessage(MSG* pMsg)
{
    // TODO: Add your specialized code here and/or call the base class
    // Intercept Ctrl + Z (Undo), Ctrl + X (Cut), Ctrl + C (Copy), Ctrl + V (Paste) and Ctrl + A (Select All)
    // before CEdit base class gets a hold of them.
    if (pMsg->message == WM_KEYDOWN && ::GetKeyState(VK_CONTROL) < 0)
        switch (pMsg->wParam)
        {
        case 'Z':
            Undo();

            return TRUE;

        case 'X':
            Cut();

            return TRUE;

        case 'C':
            Copy();

            return TRUE;

        case 'V':
            Paste();

            return TRUE;

        case 'A':
            SetSel(0, -1);

            return TRUE;
        }

    return CEdit::PreTranslateMessage(pMsg);
}

您需要在应用程序中添加键盘处理，并根据需要响应这些键组合.当您收到CTL + C时，应致电 CEdit::Copy() [ ^ ]函数，等等.

You need to add keyboard handling in your application and respond to these key combinations as required. When you receive a CTL + C you should call the C:Copy()[^] function, etc.
