准备工作
克隆代码
在github#draw.io切换需要的Tag进行下载，当前以v17.4.3为示例。
本地运行
- 安装
browser-sync或其它本地服务器工具 - 解压
drawio-X.zip压缩包，使用IDE打开 browser-sync start --server ./src/main/webapp --files .运行本地3000端口启动服务- 浏览器访问
localhost:3000即可
开启调试模式
由./src/main/webapp/index.html源码可见，通过URL参数?dev=1开启调试模式。
Notes：开启调试模式后，个别静态资源请求会报错 —— 根据报错域名devhost.jgraph.com查找对应资源，修改访问地址：
if (urlParams['dev'] == '1') {
// Used to request grapheditor/mxgraph sources in dev mode
// var mxDevUrl = document.location.protocol + '//devhost.jgraph.com/drawio/src/main';
var mxDevUrl = './';
// Used to request draw.io sources in dev mode
// var drawDevUrl = document.location.protocol + '//devhost.jgraph.com/drawio/src/main/webapp/';
var drawDevUrl = './';

定制化侧边栏面板
缩减内置面板：
- 修改
Sidebar.prototype.initPalettes() - 将
addXXXPalette()注释掉，只留下自己需要的面板即可。
- scratchpad面板如何关闭？
🙋增加自定义面板：
- 参照
src\main\webapp\js\diagramly\sidebar\Sidebar-Flowchart.js，在同目录下定义新的面板函数
自定义面板名
- 需要在
src\main\webapp\resources\dia.txt（i18n国际化）文件中配置好映射关系，e.g.追加metric=Metric—— 国际化，修改`src\main\webapp\resources\目录下对应的映射关系。
- 需要在
- 在函数
this.addPaletteFunctions(`'metric', mxResources.get('metric'`), false,...定义key值（metric）
- 在
src/main/webapp/js/grapheditor/Sidebar.js中参照Sidebar.prototype.init的111L，绑定新形状 - 在
src\main\webapp\js\diagramly\Devel.js中参照178L，注入新函数的脚本 - 在
Sidebar.prototype.initPalettes()中调用新函数即可。
修改侧边栏底部”更多图形“的内容：
- 缩减内置面板：缩减
Sidebar.prototype.init()函数中的this.entries数据元素即可。 - 隐藏“更多图形”：因为没有快捷方式打开，直接将
sidebarFooterHeight设置为0即可 —— 像最大化有快捷方式的，要注释相关代码。
EditorUi.prototype.sidebarFooterHeight = 0;定制化控件形状
🙋形状模板
参考src\main\webapp\shapes\mxFlowchart.js文件，编程语言为svg基本语法。
Notes：
- 若不需要自定义形状，该项可有可无；
- 建议与[增加自定义面板]一一对应创建；
- 文件名为
mxmetric.js自定义面板的key值
形状属性配置
createVertexTemplateEntry函数参数
createVertexTemplateEntry用于生成图形信息| 参数名 | 默认值 | 说明 | 备注 |
|---|---|---|---|
| style | -- | s: value内置 s2、s3: value外置 | - 圆角不是通过rx、ry，而是通过rounded=1定义 - shape=step;可使用内置形状，详见 src\main\webapp\js\diagramly\Editor.js 4260L- 形状映射/生成的逻辑见 src\main\webapp\mxgraph\mxClient.js 14709L- - 更多style参数参见src/main/webapp/js/diagramly/Editor.js 315L、389L、427L |

| showTitle | null | null：侧边栏预览支持浮层预览 false：侧边栏预览不支持浮层预览 | -- |
| tags | -- | -- | -- |
源码见mxCellRenderer.prototype.createShape的定义，其中根据是否是内置形状分为不同的逻辑：
null != a.style &&
((b = a.style[mxConstants.STYLE_SHAPE]),
(b =
null == mxCellRenderer.defaultShapes[b]
? mxStencilRegistry.getStencil(b)
: null),
(b = null != b ? new mxShape(b) : new (this.getShapeConstructor(a))()));对于侧边栏的预览图，见源码Sidebar.prototype.createThumb。
业务需求：修改控件缩略图的尺寸，修改源码src\main\webapp\js\grapheditor\Sidebar.js并URL上传参(urlParams['sidebar-entries'] === 'large')
// src\main\webapp\js\grapheditor\Sidebar.js
...
Sidebar.prototype.thumbWidth = 42; // 这里修改成需要尺寸大小，如100
Sidebar.prototype.thumbHeight = 42; // 这里修改成需要尺寸大小，如100
...
if (urlParams['sidebar-entries'] != 'large')
{
Sidebar.prototype.thumbPadding = (document.documentMode >= 5) ? 0 : 1;
Sidebar.prototype.thumbBorder = 1;
Sidebar.prototype.thumbWidth = 32;
Sidebar.prototype.thumbHeight = 30;
Sidebar.prototype.minThumbStrokeWidth = 1.3;
Sidebar.prototype.thumbAntiAlias = true;
}解析控件样式
/**
* 输入：mxCell实例
* 输出：mxCell实例style属性对象 —— 该方法将style字符串转为对象
*/
graph.getCurrentCellStyle(cell)获取控件DOM
// Returns the DOM nodes for the given cells.
Graph.prototype.getNodesForCells(cells) 定制控件id
// 重写mxGraphModel.prototype.createId方法
// 注意控件ID必须保证唯一，否则，程序崩溃
mxGraphModel.prototype.createId = function (a) {
var styleProperties, id;
if (a.style) {
styleProperties = mxUtils.parseStyle(a.style)
id = mxUtils.getValue(styleProperties, 'id', null)
}
if (!id) {
a = this.nextId;
this.nextId++;
}
return id ? id : this.prefix + a + this.postfix;
};
// 获取style中的id
var insertCellStyleProperties = graph.getCurrentCellStyle(insertCell)
var insertCellId = mxUtils.getValue(insertCellStyleProperties, 'id', '')新增控件属性
mxUtils.parseStyle = function(a) {
const cellProperties = a.split(';').filter(item => !!item.trim()).reduce((sum, cur) => {
const [key, value] = cur.split('=')
sum[key.trim()] = typeof value === 'string' ? value.trim() : value
return sum
}, {})
return cellProperties
}
// 新增代码逻辑定义新增字段
mxCell.prototype.__originId = null;
mxCell.prototype.__getOriginId = function () {
return this.__originId;
};
mxCell.prototype.__setOriginId = function (a) {
if (a) {
this.__originId = a;
}
};
mxCell.prototype.onInit = function () {
var s = this.getStyle()
if (s) {
var o = mxUtils.parseStyle(s)
this.__setOriginId(o.id)
}
}定制控件文本
内置Shape样式详见src\main\webapp\mxgraph\mxClient.js文件格式化后的代码第5179L。
通过this.createVertexTemplateEntry()创建的控件，文本源码详见function mxText的定义，样式见mxCellRenderer.prototype.createLabel中的a.text = new this.defaultTextShape，简单来说，通过style的fontSize可以自定义字号。
业务需求：改控件文本fontSize，this.createVertexTemplateEntry(s + 'view;portConstraint=eastwest;cloneable=0;rotatable=0;editable=0;deletable=1;resizable=0;rounded=1;snapToPoint=1;points=[[0, 0.5],[1, 0.5]];whiteSpace=wrap;fontSize=24;size=0.5;', w, h * 0.6, '曝光', '曝光', null, null, this.getTagsForStencil(gn, 'view', dt).join(' '))中的fontSize=24;
Sidebar.prototype.sidebarTitles = true可额外在侧边栏面板中展示控件label。
更新控件样式
通过原始功能判断是否有内置方法属性
有内置可直接调用
// src/main/webapp/js/diagramly/Editor.js
function createCheckbox(pName, pValue, prop)
{
var input = document.createElement('input');
input.type = 'checkbox';
input.checked = pValue == '1';
mxEvent.addListener(input, 'change', function()
{
applyStyleVal(pName, input.checked? '1' : '0', prop);
});
return input;
};
...
// 样式的改变也会触发统一事件
ui.fireEvent(new mxEventObject('styleChanged', 'keys', [mxConstants.STYLE_ROUNDED, mxConstants.STYLE_CURVED],
'values', ['0', '0'], 'cells', graph.getSelectionCells()));
// 监听处理的地方src/main/webapp/js/grapheditor/EditorUi.js 710L
this.addListener('styleChanged', mxUtils.bind(this, function(sender, evt)无内置，可参考相关逻辑自定义
定制连线样式
修改EdgeStyle即可
// src/main/webapp/js/grapheditor/Graph.js 7731L
Graph.prototype.createCurrentEdgeStyle = function()
{
var style = 'edgeStyle=' + (this.currentEdgeStyle['edgeStyle'] || 'none') + ';flowAnimation=1;';
var keys = ['shape', 'curved', 'rounded', 'comic', 'sketch', 'fillWeight', 'hachureGap',
'hachureAngle', 'jiggle', 'disableMultiStroke', 'disableMultiStrokeFill', 'fillStyle',
'curveFitting', 'simplification', 'comicStyle', 'jumpStyle', 'jumpSize'];定位相关逻辑
// src/main/webapp/js/grapheditor/EditorUi.js 1620L
graph.connectVertex(temp, dir, graph.defaultEdgeLength, mouseEvent, true, true, function(x, y, execute)
{
execute(cell);
if (ui.hoverIcons != null)
{
ui.hoverIcons.update(graph.view.getState(cell));
}
}, function(cells)
{
graph.selectCellsForConnectVertex(cells);
}, mouseEvent, this.hoverIcons);
// src/main/webapp/js/grapheditor/Graph.js 4300L
Graph.prototype.connectVertex = function(sourc
...
this.createCurrentEdgeStyle()定制控件交互性
业务需求：控件是不可编辑且不可调整尺寸的——this.createVertexTemplateEntry(s + 'view;editable=0;resizable=0;rounded=1;whiteSpace=wrap;size=0.25;', w, h * 0.6, '曝光', '曝光', null, null, this.getTagsForStencil(gn, 'view', dt).join(' ')),中的editable=0;resizable=0;

核心逻辑
// src\main\webapp\js\grapheditor\EditorUi.js核心代码
...
this.actions = new Actions(this);
...
keyHandler.bindAction = mxUtils.bind(this, function(code, control, key, shift)
{

keyHandler.bindAction(107, true, 'zoomIn'); // Ctrl+Plus
keyHandler.bindAction(109, true, 'zoomOut'); // Ctrl+Minus
keyHandler.bindAction(80, true, 'print'); // Ctrl+P
keyHandler.bindAction(79, true, 'outline', true); // Ctrl+Shift+O
...事件触发
this.editorUi.actions.get('print').funct()事件回调
源码中，大部分事件都会抛出一个自定义事件，在业务逻辑上监听该自定义事件，即可写事件回调。
下面以自定义删除事件的回调为例：
//事件监听
/**
* 锁定元素
*/
var lockCells = Object.values(graph.getModel().cells)
graph.setSelectionCells(lockCells)
var lockUnlockAction = this.editorUi.actions.get('lockUnlock').funct
var deleteAllAction = this.editorUi.actions.get('deleteAll').funct
lockUnlockAction()
graph.clearSelection()
graph.getModel().endUpdate();
function clearLabel (graph, evt) {
var eventName = evt.name
if (eventName !== 'removeCells') return
var eventTarget = evt.properties.cells[0]
/**
* 拖动Cell时，也会触发removeCells事件，此时eventTarget === undefined
* 删除Cell时，触发removeCells事件，此时eventTarget为删除的Cell实例
*/
if (!eventTarget) return
var deleteCellStyleProperties = graph.getCurrentCellStyle(eventTarget)
if (deleteCellStyleProperties.shape === 'label') return
/**
* 该逻辑会走两次
* 第一次：删除当前Cell触发
* 第二次：该逻辑中deleteAllAction()调用引发的触发，第二次需要忽略
*/
currentInstalledIndicator = null
graph.getModel().beginUpdate();
graph.setSelectionCells(Object.values(graph.getModel().cells))
lockUnlockAction()
graph.clearSelection()
graph.getModel().endUpdate();
setTimeout(() => {
/**
* 该逻辑要延时执行，因为lockUnlockAction的状态无法同步更新的view.state中，倒是deleteAllAction中的是否可删除判断逻辑无法执行后续
*/
try {
graph.getModel().beginUpdate();
graph.setSelectionCells(cellLabels)
deleteAllAction()
edges.forEach(edge => {
graph.labelChanged(edge, '', false)
})
} catch {
} finally {
graph.removeListener(clearLabel)
graph.getModel().endUpdate();
}
}, 4)
}
graph.addListener(mxEvent.REMOVE_CELLS, clearLabel)
// 源码中抛出事件的代码src/main/webapp/mxgraph/mxClient.js
mxGraph.prototype.removeCells = function (a, b) {

else {

for (
var c = this.getDeletableCells(this.getAllEdges(a)),
d = new mxDictionary(),

e++
)

};事件禁用
// src\main\webapp\js\grapheditor\Actions.js
Action.prototype.setEnabled = function(value)
{
if (this.enabled != value)
{
this.enabled = value;
this.fireEvent(new mxEventObject('stateChanged'));
}
};比如，Delete、Backspace的删除键在只选择一个控件时，是被禁用的
// src\main\webapp\js\grapheditor\EditorUi.js
var actions = ['cut', 'copy', 'bold', 'italic', 'underline', 'delete', 'duplicate',
'editStyle', 'editTooltip', 'editLink', 'backgroundColor', 'borderColor',
'edit', 'toFront', 'toBack', 'solid', 'dashed', 'pasteSize',
'dotted', 'fillColor', 'gradientColor', 'shadow', 'fontColor',
'formattedText', 'rounded', 'toggleRounded', 'strokeColor',
'sharp', 'snapToGrid'];
for (var i = 0; i < actions.length; i++)
{
this.actions.get(actions[i]).setEnabled(ss.cells.length > 0);
}Delete无法对单控件使用
在上述代码中，事件名删除delete即可。

...其他对象事件触发
graph.addListener('cellsInserted', function(sender, evt)
{
insertHandler(evt.getProperty('cells'), null, null, null, null, true, true);
});
...

// this.showDialog(dlg.container, (rowLimit < 3) ? 200 : 300,

// 新增渲染逻辑

var prev = Editor.useLocalStorage;
this.editorUi.createFile(this.editorUi.defaultFilename,
null, null, null, null, null, null, true);
Editor.useLocalStorage = prev;
}
弹窗结构：
// src/main/webapp/js/diagramly/Dialogs.js

...
// 稍后再决定的逻辑
var later = document.createElement('span');

graph.dblClick = function(evt, cell)
{
if (this.isEnabled())
{
if (cell == null && ui.sidebar != null && !mxEvent.isShiftDown(evt) &&

// }), 30);
}
else
{
graphDblClick.apply(this, arguments); // 双击编辑，禁掉就无法编辑了
}
}
};
隐藏右键菜单
// src/main/webapp/js/grapheditor/EditorUi.js 382L
if (mxClient.IS_IE && (typeof(document.documentMode) === 'undefined' || document.documentMode < 9))
{
mxEvent.addListener(this.diagramContainer, 'contextmenu', linkHandler);
}
else
{
// Allows browser context menu outside of diagram and sidebar
this.diagramContainer.oncontextmenu = linkHandler;
}
隐藏Menus
实践
// src\main\webapp\js\grapheditor\Menus.js
// Menus.prototype.defaultMenuItems = ['file', 'edit', 'view', 'arrange', 'extras', 'help'];
Menus.prototype.defaultMenuItems = [];为什么
- 不注释掉
src\main\webapp\js\grapheditor\EditorUi.js中的this.menus = this.createMenus();逻辑？ - 不注释掉
src\main\webapp\js\diagramly\Devel.js中的Menus脚本？
因为代码依赖问题，注释掉的话，需要调整其它JS脚本的逻辑。
隐藏工具栏Toolbar
实践
// src\main\webapp\js\grapheditor\Toolbar.js
function Toolbar(editorUi, container)
{
this.editorUi = editorUi;
this.container = container;
this.staticElements = [];
// this.init();为什么
- 不注释掉
src\main\webapp\js\grapheditor\EditorUi.js中的EditorUi.prototype.createToolbar逻辑？ - 不注释掉
src\main\webapp\js\diagramly\Devel.js中的Toolbar脚本？
因为代码依赖问题，注释掉的话，需要调整其它JS脚本的逻辑。
隐藏配置面板Format
实践
控件的配置面板源码在Format.prototype.immediateRefresh的定义中，这里我们不去调用immediateRefresh函数，即不会生成各项配置面板——空面板，但，空面板宽度width还是有的，通过this.editorUi.toggleFormatPanel(false)隐藏。
// src\main\webapp\js\grapheditor\Format.js
Format.prototype.refresh = function()
{
if (this.pendingRefresh != null)
{
window.clearTimeout(this.pendingRefresh);
this.pendingRefresh = null;
}
this.pendingRefresh = window.setTimeout(mxUtils.bind(this, function()
{
// this.immediateRefresh();
this.editorUi.toggleFormatPanel(false);
}));
};为什么
不采用以下方式隐藏——默认UI模式下可以的，min模式下会报错。

打包部署
通过链接下载打包工具Ant，以1.9.16版本为例，下载解压后，切换到解压后的目录，依次运行build.bat或build.sh，bootstrap.bat或bootstrap.sh。
切换到项目目录下，ant -file ./etc/build/build.xml，执行结束后会替换原有的线上文件。
详情见github官方文档。
Notes:
切换到解压后的目录
- 必须执行，该脚本内的访问路径是相对路径，必须切换到解压后的目录执行脚本
ant -file ./etc/build/build.xml
- Mac OS需要将ant设置为全局，win执行脚本时默认了全局
