详细描述

编辑器中的 3D 场景视口占位节点。

SceneNode 自身不创建 UIObject；标题栏由普通 UI 子节点绘制，后端把场景先画入离屏纹理，再依据 ViewportNode 的布局框合成到交换链。这样标题拖拽不会穿透相机。

构造及析构函数说明

◆ SceneNode()

SceneNode::SceneNode ( )

函数调用图:

成员函数说明

◆ HasInteractiveGeometry()

bool SceneNode::HasInteractiveGeometry ( ) const

即时声明不得覆盖用户拖动或拉伸后提交的几何。

◆ SetProperty()

bool SceneNode::SetProperty	(	const std::string &	name,
		const std::string &	value )

overridevirtual

重载 z8::ui::BehaviorNode .

函数调用图:

◆ TypeName()

const char * z8::ui::SceneNode::TypeName ( ) const

inlineoverridevirtual

重载 z8::ui::BaseNode .

◆ Viewport()

const BaseNode & z8::ui::SceneNode::Viewport ( ) const

inline

后端只在内容区合成场景，标题栏始终由 UI 通道覆盖绘制。

类成员变量说明

◆ TitleBarNode

RectNode* z8::ui::SceneNode::TitleBarNode = nullptr

◆ TitleHeight

float z8::ui::SceneNode::TitleHeight = 0.0f

private

构造时取自 Theme；保留实例值以支持声明层覆盖标题高度。

◆ TitleNode

TextNode* z8::ui::SceneNode::TitleNode = nullptr

◆ ViewportNode

SceneViewportNode* z8::ui::SceneNode::ViewportNode = nullptr
