类成员变量说明

Behaviors

std::vector<std::unique_ptr<IBehavior> > z8::ui::BehaviorNode::Behaviors

CapturedBehavior

IBehavior* z8::ui::BehaviorNode::CapturedBehavior = nullptr

Focusable

bool z8::ui::BehaviorNode::Focusable = false

控件是否可取得键盘焦点；普通容器保持 false，避免点击面板吞掉快捷键。

Focused

bool z8::ui::BehaviorNode::Focused = false

Layout 管理的唯一键盘焦点状态，不与 Hover/Pressed 生命周期混用。

HitTestVisible

bool z8::ui::BehaviorNode::HitTestVisible = false

Hovered

bool z8::ui::BehaviorNode::Hovered = false

指针当前位于控件命中区域；只用于视觉反馈，不改变事件路由。

Pressed

bool z8::ui::BehaviorNode::Pressed = false

左键手势尚未结束；捕获移出控件后仍保持 Pressed 视觉。
