用于列表控件的 C++ 中的停靠/锚点替代方案

问题描述

在 .NET 中有 Anchor &每次调整窗口大小时都可以使控件响应的停靠属性.

In .NET there are Anchor & Dock properties that can make the controls responsive whenever you resize the window.

我想用这个 C++ 列表控件做类似的事情.基本上我想将它停靠在对话框中，所以当我调整窗口大小时，它应该调整大小.

I want to do something similar with this C++ List Control. Basically I want to dock it in the dialog, so when I resize the window, it should be resizing.

推荐答案

Windows API 中没有对接支持.您必须通过处理 手动实现它WM_SIZE 消息:

There is no docking support in the Windows API. You'll have to implement it manually by handling the WM_SIZE message:

case WM_SIZE: {
    UINT width = LOWORD(lParam);
    UINT height = HIWORD(lParam);

    // IDC_LIST1 will occupy the entire client area of its parent.
    // Adjust as needed.
    MoveWindow(GetDlgItem(hWnd, IDC_LIST1),
        0, 0, width, height, TRUE);

    return TRUE;
}
