DoEasy 函数库中的图形（第八十三部分）：抽象标准图形对象类·进阶篇

（2/3）·手工创建的标准图形对象如何被函数库接管？抽象类先收下所有对象共有的属性与方法

新手友好第 2/3 篇

很多交易者把 MT5 里手画的箭头、趋势线当成一次性标注，库里没法统一改属性就懒得管。其实只要给每类标准对象配一个绑定类，面板菜单就能替你批量调属性，省掉重复右键。

「图形对象归属与属性枚举的底层定义」

在自建图形库时，先要把对象的「身份」和「归属」用枚举钉死。ENUM_GRAPH_OBJ_BELONG 只给两个值：GRAPH_OBJ_BELONG_PROGRAM 表示对象由程序创建并受控，GRAPH_OBJ_BELONG_NO_PROGRAM 则是图表上那些不属于当前 EA/脚本的散落对象。对象类型再细分为 ENUM_GRAPH_ELEMENT_TYPE：从 GRAPH_ELEMENT_TYPE_STANDART 标准对象，到 ELEMENT、SHADOW_OBJ、FORM、WINDOW 五类。实际写面板时，WINDOW 和 FORM 最常用来做可拖拽容器，SHADOW_OBJ 多用于鼠标悬停的临时高亮层。整数属性枚举 ENUM_GRAPH_OBJ_PROP_INTEGER 从 0 开始排：GRAPH_OBJ_PROP_ID=0 是对象唯一 ID，紧接着 TYPE、ELEMENT_TYPE、BELONG、CHART_ID、WND_NUM、NUM。CHART_ID 与 WND_NUM 组合能定位对象挂在哪个图表、哪个子窗口，NUM 则是列表内序号。开 MT5 把这段枚举贴进头文件，编译后用一个 Print() 轮询 GRAPH_OBJ_PROP_BELONG 的两个常量值，能确认库里「程序内/程序外」对象的过滤逻辑是否按预期分流。外汇与贵金属图表对象受报价跳动影响，高频重绘时归属判断失误可能导致对象泄漏，属高风险操作。

◍ 图形对象属性的枚举分层

在 MT5 里给图表挂对象，先得搞清楚属性枚举的归类逻辑。一类是所有图形对象通用的底层属性，另一类是按对象类型才生效的专属属性，混用会导致赋值无效或运行时报错。通用属性里，GRAPH_OBJ_PROP_CREATETIME 记录对象创建时间，GRAPH_OBJ_PROP_TIMEFRAMES 控制多周期可见性，GRAPH_OBJ_PROP_BACK 决定是否为背景层对象，GRAPH_OBJ_PROP_ZORDER 影响鼠标点击图表的事件优先级，GRAPH_OBJ_PROP_HIDDEN 可隐藏对象在终端列表中的名称。专属属性则包括坐标时间 GRAPH_OBJ_PROP_TIME、颜色 GRAPH_OBJ_PROP_COLOR、线型 GRAPH_OBJ_PROP_STYLE 与宽度 GRAPH_OBJ_PROP_WIDTH，以及填充 GRAPH_OBJ_PROP_FILL。文本类对象还有 GRAPH_OBJ_PROP_READONLY、GRAPH_OBJ_PROP_ALIGN、GRAPH_OBJ_PROP_FONTSIZE 等可控项。趋势线相关的射线开关值得单独记：GRAPH_OBJ_PROP_RAY_LEFT 向左延伸，GRAPH_OBJ_PROP_RAY_RIGHT 向右延伸，GRAPH_OBJ_PROP_RAY 则让竖线穿透图表所有子窗口。外汇与贵金属图表对象受报价跳空影响，射线类对象可能在大跳空后视觉错位，实操前建议在 MT5 用 EURUSD 的 M1 数据手动建一个对象验证属性响应。

图形对象整数属性的尾部枚举与计数

上面这段枚举收尾，补齐了 MT5 图形对象整数属性里偏「界面与内嵌图表」的一组成员。 GRAPH_OBJ_PROP_ELLIPSE 控制斐波那契弧是否画完整椭圆；GRAPH_OBJ_PROP_ARROWCODE 决定 Arrow 对象的箭头样式代码；GRAPH_OBJ_PROP_ANCHOR 是对象绑定点的对齐位置。 GRAPH_OBJ_PROP_XDISTANCE / YDISTANCE 用像素定义对象距基准角的偏移；GRAPH_OBJ_PROP_DIRECTION 管甘氏对象的趋势方向；GRAPH_OBJ_PROP_DEGREE 和 DRAWLINES 则对应艾略特波浪标注的层级与连线显示。再往下是 OBJ_CHART 内嵌图表相关：CHART_OBJ_PERIOD 设周期，DATE_SCALE / PRICE_SCALE / CHART_SCALE 控制时间轴、价格轴与整体缩放是否显示及比例。 XSIZE / YSIZE 以像素定宽高，XOFFSET / YOFFSET 是可见区域左上角坐标；BGCOLOR、BORDER_TYPE、BORDER_COLOR 管 Edit / Button / Label 类控件的背景与边框。枚举闭括号后紧跟 #define GRAPH_OBJ_PROP_INTEGER_TOTAL (51)，说明整套整数属性共 51 个。开 MT5 在 <stdlib> 或自定义头文件里搜这个宏，能直接核对自己平台版本是否一致，若数目不符可能要重编译依赖库。

「图形对象属性的枚举拆分与排序偏移」

在 MT5 里给标准图形对象做批量排序前，得先理清它三类属性的底层编号。整数属性、实数属性、字符串属性各自成枚举，且后两类靠前面类型的 TOTAL 常量做下标偏移，不是从 0 重排。实数属性枚举 ENUM_GRAPH_OBJ_PROP_DOUBLE 从 GRAPH_OBJ_PROP_INTEGER_TOTAL 接着数，定义了 5 个：价格坐标、水平值、缩放、角度、标准差通道偏离，宏 GRAPH_OBJ_PROP_DOUBLE_TOTAL 写死为 5，SKIP 为 0 表示没有跳过不参与排序的项。字符串属性枚举 ENUM_GRAPH_OBJ_PROP_STRING 起点是 INT_TOTAL+DBL_TOTAL，共 7 个：对象名、文本、提示框、水平描述、字体、位图文件名、Chart 对象品种。宏 GRAPH_OBJ_PROP_STRING_TOTAL 等于 7，这是后续按名称或品种筛对象时的索引上限。排序模式的下界用两个宏算出：FIRST_GRAPH_OBJ_DBL_PROP 等于整数总数减跳过数，FIRST_GRAPH_OBJ_STR_PROP 再叠加实数总数减跳过数。你开 MT5 的 MetaEditor 把这套枚举贴进 EA，就能直接拿 ObjectGetInteger/ObjectGetString 按索引遍历，不用硬背属性 ID。外汇与贵金属图表对象受报价跳空影响，遍历结果可能漏掉非活跃时段手绘线，属正常概率现象。

◍ 图形对象排序枚举的逐条含义

在 MT5 的 ObjectsTotal / ObjectGet 相关调用里，经常需要按某种规则批量枚举图表上的图形对象。系统提供了一组 SORT_BY_GRAPH_OBJ_* 枚举，用来决定 ObjectsFind / 集合遍历时的排列依据。下面这段枚举定义了 26 个排序维度，从对象 ID 到水平线颜色都有覆盖。比如 SORT_BY_GRAPH_OBJ_CREATETIME 按创建时间排，SORT_BY_GRAPH_OBJ_ZORDER 按点击接收优先级排，SORT_BY_GRAPH_OBJ_TIMEFRAMES 按各周期可见性排。实盘写 EA 时，如果你要清理某图表子窗口（SORT_BY_GRAPH_OBJ_WND_NUM）里所有手工画的线，用对应枚举拿到的列表顺序会更可控，避免误删主图对象。外汇与贵金属杠杆高，脚本批量删对象前务必在模拟盘验一遍。

图形对象排序枚举的尾部清单

在 MT5 的 ObjectsTotal / ObjectGetInteger 体系里，图形对象排序方式走到 SORT_BY_GRAPH_OBJ_LEVELSTYLE 之后，还有一整组以 SORT_BY_GRAPH_OBJ_ 开头的枚举量，专门覆盖画线样式、宽度、文字对齐、字体尺寸等细分属性。这些枚举大多用于 ObjectsSort() 的排序模式参数，例如 SORT_BY_GRAPH_OBJ_RAY_LEFT 对应「射线向左延伸」属性，SORT_BY_GRAPH_OBJ_RAY_RIGHT 对应「射线向右延伸」，SORT_BY_GRAPH_OBJ_RAY 则针对「垂直线穿透图表所有子窗口」这一开关。斐波那契弧、江恩、艾略特等复杂对象也有专属排序键：SORT_BY_GRAPH_OBJ_ELLIPSE 管「显示完整椭圆」，SORT_BY_GRAPH_OBJ_DIRECTION 管「江恩对象趋势」，SORT_BY_GRAPH_OBJ_DEGREE 与 SORT_BY_GRAPH_OBJ_DRAWLINES 分别管「艾略特波浪标注层级」和「是否显示波浪连线」。内嵌图表对象（Chart object）同样可排：从 OBJ_CHART_ID、周期、时间/价格轴显示旗标到图表缩放比例，对应 SORT_BY_GRAPH_OBJ_CHART_OBJ_CHART_SCALE 等四个枚举。外汇与贵金属图表上滥用这些排序可能拖慢刷新，属高风险环境下的性能细节，建议开 MT5 用以下片段自查枚举值。

交给小布盯盘看盘口

这些对象属性诊断小布盯盘的 AIGC 已内置，打开对应品种页即可看到哪些手工图形被库接管、哪些还是游离状态，你只管决定要不要统一整理。

常见问题

抽象类只放所有图形共有的属性读取方法，箭头代码这类专属属性在衍生类里实现，引用时只能碰到对象自己有的那部分。

函数库默认不自动接管手工对象，用户触发关联菜单后绑定类才生效，之后就能用代码改颜色、射线开关而不用逐个右键。

可以，小布会列出当前品种页的手工图形及其绑定状态，未纳入库管理的会标出，方便你一键整理或忽略。

类方法内部封装了 ObjectGetInteger、ObjectGetDouble 等终端函数，对外只暴露语义化接口，避免直接拼属性常量。

本篇铺完抽象基类后，后续会逐类实现箭头、趋势线等衍生对象，并回到基于 CCanvas 的图形面板。
