Win32窗口所有者vs窗口父级? [英] Win32 window Owner vs window Parent?

问题描述

在Win32编程中，窗口的父级和窗口的所有者之间有什么区别?我以为知道了，然后遇到了这段代码:

In Win32 programming, what is the difference between a window's parent and a window's owner? I thought I had it figured out, then I came across this code:

SetWindowLong(handle, GWL_HWNDPARENT, foo);

这实际上设置了窗口的所有者，而不是父窗口-尽管使用了GWL_HWNDPARENT.父母/所有者这两个术语可以互换吗，或者实际上有区别吗?

This actually sets the window's owner, not the parent - despite the GWL_HWNDPARENT being used. Are the terms parent/owner interchangeable, or is there actually a difference?

推荐答案

所有者是负责控件或对话框的Window *(例如，负责创建/销毁窗口).

Owner is the Window* responsible for a control or dialog (for example, responsible for creating/destroying the window).

父级是窗口链中控件或对话框的下一个高级窗口*，但实际上并不对其负责(不必关心其生命周期等).窗口的父级也可以是其所有者.

Parent is the next-senior window* to a control or dialog in the window chain, but isn't actually responsible for it (doesn't necessarily care about its lifecycle, etc). A window's parent can also be its owner.

*窗口与窗口:窗口是显示在屏幕上的实际窗口；窗口是具有HWND的任何对象(包括按钮，面板等).

*Window vs window: Window is an actual window displayed on the screen; window is any object with a HWND (includes buttons, panels, etc).
