形状边框样式

SpreadJS 支持为形状和连接符自定义边框样式,包括颜色、透明度、宽度、线型、端点样式及连接样式等属性。通过灵活的样式配置,可满足报表、流程图等场景中对形状视觉效果的精细化需求。

概述 本 Demo 展示了如何为形状和连接符设置自定义边框样式。Demo 中创建了两个基础形状(椭圆和矩形)和两个连接符形状(直线和折线),并提供交互式界面,允许用户选择形状后修改其边框的颜色、透明度、宽度、线型、端点样式和连接样式。 实现思路 初始化工作表,创建两个基础形状(椭圆、矩形)和两个连接符形状(直线、折线) 监听 ShapeSelectionChanged 事件,检测用户选中的形状类型 根据选中状态显示或隐藏边框属性设置面板 为每个边框属性(颜色、透明度、宽度、线型、端点样式、连接样式)提供输入控件和设置按钮 用户点击设置按钮时,获取当前选中的所有形状,修改其边框样式并刷新工作表 代码解析 创建形状和连接符 这段代码演示了如何使用 shapes.add() 方法创建基础形状,以及使用 shapes.addConnector() 方法创建连接符形状。shapes.add() 方法的参数依次为形状名称、形状类型、左边距、上边距、宽度和高度。AutoShapeType.oval 和 AutoShapeType.rectangle 分别表示椭圆和矩形类型,ConnectorType.straight 和 ConnectorType.elbow 分别表示直线和折线连接符。 监听形状选择事件 这段代码监听 ShapeSelectionChanged 事件,当用户选择形状时触发。通过 shapes.all() 获取所有形状,再使用 isSelected() 方法筛选出当前选中的形状,并使用 instanceof 判断形状类型(基础形状或连接符形状)。 修改形状边框样式 这是核心的样式修改函数。首先获取所有选中的形状,然后遍历每个形状,通过 shape.style() 获取当前样式对象,修改 line 属性的指定字段(如 color、width 等),最后调用 shape.style(shapeStyle) 应用新样式,并调用 sheet.repaint() 刷新显示。 边框样式属性说明 line.color:边框颜色,使用十六进制颜色值或颜色名称 line.transparency:边框透明度,取值范围为 0(不透明)到 1(完全透明) line.width:边框宽度,单位为像素 line.lineStyle:边框线型,使用 PresetLineDashStyle 枚举值,如 solid(实线)、dash(虚线)、dot(点线)等 line.capType:线条端点样式,使用 LineCapStyle 枚举值,如 flat(平端)、square(方端)、round(圆端) line.joinType:线条连接样式,使用 LineJoinStyle 枚举值,如 round(圆角连接)、miter(尖角连接)、bevel(斜角连接) 运行效果 工作表初始显示两个白色填充的形状(椭圆和矩形)和两个连接符形状(直线和折线) 点击选择任意形状后,右侧面板会显示边框属性设置选项 修改颜色、透明度、宽度等属性后点击对应的"设置"按钮,可以看到选中形状的边框样式实时更新 可以同时选择多个形状,批量修改它们的边框样式 边框样式支持实时预览,所有修改立即生效
