[C++知识库]duilib内核原理分析 之 窗口 关闭流程

一、duilib 窗口关闭

1、窗口关闭代码

void Window::Close(UINT nRet)
{
	if (m_bFakeModal)
	{
		auto parent_hwnd = GetWindowOwner(m_hWnd);
		ASSERT(::IsWindow(parent_hwnd));
		::EnableWindow(parent_hwnd, TRUE);
		::SetFocus(parent_hwnd);
		m_bFakeModal = false;
	}
	ASSERT(::IsWindow(m_hWnd));
	if (!::IsWindow(m_hWnd)) return;

	if (m_pRoot && IsWindowsVistaOrGreater()) {
		m_pRoot->SetVisible(false);
		auto closeCallback = [this, nRet]() {
			this->PostMessage(WM_CLOSE, (WPARAM)nRet, 0L);
		};
		TimerManager::GetInstance()->AddCancelableTimer(m_closeFlag.GetWeakFlag(), closeCallback, 300, 1);
	}
	else {
		PostMessage(WM_CLOSE, (WPARAM)nRet, 0L);
	}
}

2、延时关闭

这里重要是这一段

		m_pRoot->SetVisible(false);
		auto closeCallback = [this, nRet]() {
			this->PostMessage(WM_CLOSE, (WPARAM)nRet, 0L);
		};
		TimerManager::GetInstance()->AddCancelableTimer
