详细描述

Win32 HWND 与保留式事件目标之间的共享适配层。

该类只负责 WNDPROC 对象转发、坐标归一化和输入状态，不拥有 HWND，也不 参与交换链或窗口业务生命周期；主 Application 与 Floating host 因而可以 复用同一套平台消息语义，同时保留各自的 resize/render 策略。

构造及析构函数说明

Win32WindowHost()

z8::Win32WindowHost::Win32WindowHost ( )

成员函数说明

AttachWindow()

void Win32WindowHost::AttachWindow ( HWND window, EventTarget & inputTarget, HWND coordinateWindow = nullptr )

protected

绑定现有 HWND；coordinateWindow 决定事件坐标系，Floating window 可将 本地客户坐标统一映射回主 Layout 客户区。

函数调用图:

这是这个函数的调用关系图:

DetachWindow()

void Win32WindowHost::DetachWindow ( )

protected

这是这个函数的调用关系图:

DispatchInputMessage()

bool Win32WindowHost::DispatchInputMessage ( HWND window, UINT message, WPARAM wParam, LPARAM lParam, LRESULT & result )

protected

处理共享输入消息；返回 true 表示 result 已包含窗口过程结果。

HandleWindowMessage()

virtual LRESULT z8::Win32WindowHost::HandleWindowMessage ( HWND window, UINT message, WPARAM wParam, LPARAM lParam )

protectedpure virtual

在 z8::Application , 以及 z8::DX12FloatingWindowManager::Host 内被实现.
