构造及析构函数说明

Host()

z8::DX12FloatingWindowManager::Host::Host ( DX12Render & render, ui::BaseNode & root )

函数调用图:

~Host()

z8::DX12FloatingWindowManager::Host::~Host ( )

成员函数说明

Draw()

void z8::DX12FloatingWindowManager::Host::Draw ( )

inline

函数调用图:

这是这个函数的调用关系图:

GetGroup()

ui::PanelGroupNode * z8::DX12FloatingWindowManager::Host::GetGroup ( ) const

inline

GetRoot()

ui::BaseNode * z8::DX12FloatingWindowManager::Host::GetRoot ( ) const

inline

HandleWindowMessage()

LRESULT z8::DX12FloatingWindowManager::Host::HandleWindowMessage ( HWND window, UINT message, WPARAM wParam, LPARAM lParam )

inlineoverrideprivatevirtual

实现了 z8::Win32WindowHost.

函数调用图:

IsClosePending()

bool z8::DX12FloatingWindowManager::Host::IsClosePending ( ) const

inline

IsRootAlive()

bool z8::DX12FloatingWindowManager::Host::IsRootAlive ( ) const

inlineprivate

判断非拥有 Root 是否仍由 Layout 持有。

Panel 提交到其他 Group 时会在当前 WNDPROC 内销毁旧 Group，而 Host 必须 延迟到下一帧 Reconcile 才能安全销毁 HWND。Nodes 已在提交末尾重建， 所以纯地址查询可以封住这段窗口消息重入期，且不会解引用悬空指针。

这是这个函数的调用关系图:

RebuildBatch()

void z8::DX12FloatingWindowManager::Host::RebuildBatch ( )

inline

函数调用图:

这是这个函数的调用关系图:

RenderInteractiveResizeFrame()

void z8::DX12FloatingWindowManager::Host::RenderInteractiveResizeFrame ( )

inlineprivate

函数调用图:

这是这个函数的调用关系图:

Resize()

void z8::DX12FloatingWindowManager::Host::Resize ( )

inlineprivate

函数调用图:

这是这个函数的调用关系图:

ResolveNonClientHit()

LRESULT z8::DX12FloatingWindowManager::Host::ResolveNonClientHit ( LPARAM lParam ) const

inlineprivate

将 Floating HWND 的可见边缘统一交给 Win32 非客户区状态机。

point 使用屏幕坐标；ScreenToClient 后允许出现负数和超出客户区的值， 因而同一判断同时覆盖系统 frame 外侧与 UI 客户区内侧，消除两套 resize 捕获在左/上边缘竞争导致的概率性失效。

函数调用图:

这是这个函数的调用关系图:

SynchronizeRectFromWindow()

void z8::DX12FloatingWindowManager::Host::SynchronizeRectFromWindow ( )

inlineprivate

函数调用图:

这是这个函数的调用关系图:

SynchronizeWindow()

void z8::DX12FloatingWindowManager::Host::SynchronizeWindow ( )

inline

函数调用图:

这是这个函数的调用关系图:
