详细描述

封装 viewport、content、滚动条和 ScrollBehavior 的可复用滚动容器。

外部子节点统一添加到 ContentHost；Panel 不再了解滚动范围、裁剪或滑块绑定， 列表和树控件也可直接复用该组合节点。

构造及析构函数说明

ScrollNode()

ScrollNode::ScrollNode

函数调用图:

成员函数说明

ContentHost()

BaseNode * z8::ui::ScrollNode::ContentHost ( )

inlineoverridevirtual

重载 z8::ui::BaseNode .

这是这个函数的调用关系图:

GetScrollBehavior()

ScrollBehavior * z8::ui::ScrollNode::GetScrollBehavior ( )

inline

这是这个函数的调用关系图:

SetVerticalBarInsets()

void ScrollNode::SetVerticalBarInsets	(	float	top,
		float	right,
		float	bottom )

这是这个函数的调用关系图:

TypeName()

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