应用详情

大家好,今天小编为大家分享关于gg修改器不root怎么使用_gg修改器不需要root使用方法的内容,赶快来一起来看看吧。

GG-Editor 是基于 G6-Editor 进行二次封装的一款可视化操作应用框架,不过目前相关的使用说明文档太稀少了,没有一个完整的项目应用案例,还有就是核心代码 gg-editor-core 没有开源,那么今天就教大家如何基于 GG-Editor 开发一款脑图应用。

一、介绍

本项目是基于 GG-Editor 进行开发的脑图应用,基本上是一个较为完整的应用了,可以说已经预先给你们把坑踩过了,另外本项目所有代码基本可以很快速的实现一个流程图应用,因为基本的 API 使用上是相同的。 另外,本文不会过多的讲述官方文档有的内容,会注重于使用上。

二、使用

安装和使用 GG-Editor 可直接通过 npm 或 yarn 安装依赖

npm install –save gg-editor

下面我们快速进入开发,首先上 github 上把项目拉取到本地 /alibaba/GGE…,我们将它自带的 Demo 作为模版,在此基础上进行开发。

执行命令 yarn run start 后启动效果图

下面我们对项目进行改造

1. 自定义节点

官方文档: http:///docs/api/registerNode.en-US.html

在 components 文件夹下新增 `EditorCustomNode/index.jsx`

import React, { Fragment } from ’react’;
import { RegisterNode } from ’gg-editor’;

import PLUS_URL from ’@/assets/plus.svg’;
import MINUS_URL from ’@/assets/minus.svg’;
import CATE_URL from ’@/assets/docs.svg’;
import CASE_URL from ’@/assets/file.svg’;

const ICON_SIZE = 16;
const COLLAPSED_ICON = ’node-inner-icon’;

function getRectPath(x: string | number, y: any, w: number, h: number, r: number) {
if (r) {
return [
[’M’, +x + +r, y],
[’l’, w – r * 2, 0],
[’a’, r, r, 0, 0, 1, r, r],
[’l’, 0, h – r * 2],
[’a’, r, r, 0, 0, 1, -r, r],
[’l’, r * 2 – w, 0],
[’a’, r, r, 0, 0, 1, -r, -r],
[’l’, 0, r * 2 – h],
[’a’, r, r, 0, 0, 1, r, -r],
[’z’],
];
}

const res = [[’M’, x, y], [’l’, w, 0], [’l’, 0, h], [’l’, -w, 0], [’z’]];

res.toString = toString;

return res;
}

class EditorCustomNode extends React.Component {
render() {
const config = {
// 绘制标签
// drawLabel(item) {
// },

// 绘制图标
afterDraw(item) {
const model = item.getModel();
const group = item.getGraphicGroup();

const label = group.findByClass(’label’)[0];
const labelBox = label.getBBox();

const { width } = labelBox;
const { height } = labelBox;
const x = -width / 2;
const y = -height / 2;

const { type, collapsed, children } = model;

// 折叠状态图标
if (type === ’cate’ && children && children.length > 0) {
group.addShape(’image’, {
className: COLLAPSED_ICON,
attrs: {
img: collapsed ? PLUS_URL : MINUS_URL,
x: x – 24,
y: y – 2,
width: ICON_SIZE,
height: ICON_SIZE,
style: ’cursor: pointer’,
},
});
}
// 文件类型图标
group.addShape(’image’, {
attrs: {
img: type === ’cate’ ? CATE_URL : CASE_URL,
x: children && children.length > 0 ? x + 4 : x – 12,
y: y – 2,
width: ICON_SIZE,
height: ICON_SIZE,
},
});
},

// 对齐标签
adjustLabelPosition(item, labelShape) {
const size = this.getSize(item);
const padding = this.getPadding(item);
const width = size[0];
const labelBox = labelShape.getBBox();

labelShape.attr({
x: -width / 2 + padding[3],
y: -labelBox.height / 2,
});
},

// 内置边距
// [上, 右, 下, 左]
getPadding(item) {
const model = item.getModel();
const { children } = model;
if (children && children.length > 0) {
return [12, 8, 12, 60];
}
return [12, 8, 12, 38];
},

// 标签尺寸
// [宽, 高]
getSize(item) {
const group = item.getGraphicGroup();

const label = group.findByClass(’label’)[0];
const labelBox = label.getBBox();

const padding = this.getPadding(item);

return [
labelBox.width + padding[1] + padding[3],
labelBox.height + padding[0] + padding[2],
];
},

// 节点路径
// x, y, w, h, r
getPath(item) {
const size = this.getSize(item);
const style = this.getStyle(item);

return getRectPath(-size[0] / 2, -size[1] / 2, size[0] + 4, size[1], style.radius);
},

// 节点样式
getStyle(item) {
return {
// stroke: ’#d9d9d9’,
radius: 2,
lineWidth: 1,
};
},

// 标签样式
getLabelStyle(item) {
return {
fill: ’rgba(0,0,0,0.65)’,
lineHeight: 18,
fontSize: 16,
};
},

// 激活样式
getActivedStyle(item) {
return {
stroke: ’#096dd9’,
};
},

// 选中样式
getSelectedStyle(item) {
return {
stroke: ’#096dd9’,
};
},
};

return (
<Fragment>
<RegisterNode name=”mind-base” config={config} extend=”mind-base” />
<RegisterNode name=”custom-node” config={config} extend=”mind-base” />
</Fragment>
);
}
}

export default EditorCustomNode;

修改 Mind 文件夹下新增并新增如下代码

import EditorCustomNode from ’../components/EditorCustomNode’;

<Mind data={data} className={styles.mind}
// rootShape 自定义根节点
// rootShape=”custom-root”
firstSubShape=”custom-node”
secondSubShape=”custom-node”
/>
{/* 自定义节点 */}
<EditorCustomNode />

2. 自定义快捷事件

官方文档:http:///docs/api/registerCommand.en-US.html

在 components 文件夹下新增 `EditorCommand/index.jsx`

function addNodeCall(editor, node, id, type) {
const graph = editor.getGraph();
const model = node.getModel();
const sideNode = editor.getFirstChildrenBySide(’left’);
const currentNode = sideNode[0] && graph.find(sideNode[0].id);
return graph.add(’node’, {
id,
parent: node.id,
label: ’新建节点’,
type,
side: model.children.length > 2 ? ’left’ : ’right’,
nth: currentNode ? graph.getNth(currentNode) : void 0,
});
}

class CustomCommand extends React.Component {
componentDidMount() {
document.addEventListener(’keydown’, event => {
event.preventDefault();
});

export default CustomCommand;

修改 Mind 文件夹下新增并新增如下代码

import EditorCommand from ’@/component/EditorCommand’;

<Mind
className={styles.mind}
data={mindData}
// rootShape=”custom-root”
firstSubShape=”custom-node”
secondSubShape=”custom-node”
graph={{

customExpand: true, // ⌘ + B / Ctrl + B 展开
customCollapse: true, // ⌘ + B / Ctrl + B 折叠
}}
/>

{/* 自定义快捷事件 */}
<EditorCommand />

3. 自定义右键菜单

官方文档:http:///docs/api/contextMenu.en-US.html

修改 EditorContextMenu 下的 MindContextMenu.js 文件

import React from ’react’;
import { NodeMenu, CanvasMenu, ContextMenu } from ’gg-editor’;
import MenuItem from ’./MenuItem’;
import styles from ’./index.less’;

const MindContextMenu = () => (
<ContextMenu className={styles.contextMenu}>
<NodeMenu>
<mand=”customAppendCase” icon=”append” text=”Enter 添加同级 case” />
<mand=”customAppendChildCase” icon=”append-child” text=”Tab 添加下级 case” />
<mand=”customAppendCate” icon=”append” text=”⌘ + N 添加同级 cate” />
<MenuItem
command=”customAppendChildCate”
icon=”append-child”
text=”⌘ + ⇧ + N 添加下级 cate ”
/>
<mand=”customCollapse” icon=”collapse” text=”⌘ + B / Ctrl + B 折叠” />
<mand=”customExpand” icon=”expand” text=”⌘ + B / Ctrl + B 展开” />
<mand=”delete” text=”Delete / BackSpace 删除” />
</NodeMenu>
<CanvasMenu>
<mand=”undo” text=”撤销” />
<mand=”redo” text=”重做” />
</CanvasMenu>
</ContextMenu>
);

export default MindContextMenu;

4. 自定义工具条

官方文档:http:///docs/api/toolbar.en-US.html

import React from ’react’;
import { Divider } from ’antd’;
import { Toolbar } from ’gg-editor’;
import ToolbarButton from ’./ToolbarButton’;
import styles from ’./index.less’;

const MindToolbar = () => (
<Toolbar className={styles.toolbar}>
<mand=”undo” text=”⌘ + Z 撤销” />
<mand=”redo” text=”⇧ + ⌘ + Z 重做” />
<Divider type=”vertical” />
<mand=”zoomIn” icon=”zoom-in” text=”放大” />
<mand=”zoomOut” icon=”zoom-out” text=”缩小” />
<mand=”autoZoom” icon=”fit-map” text=”自适应比例” />
<mand=”resetZoom” icon=”actual-size” text=”原始比例” />
<Divider type=”vertical” />
<mand=”customAppendCase” icon=”append” text=”Enter 添加同级 case” />
<mand=”customAppendChildCase” icon=”append-child” text=”Tab 添加下级 case” />
<Divider type=”vertical” />
<mand=”customAppendCate” icon=”append” text=”⌘ + N 添加同级 cate” />
<ToolbarButton
command=”customAppendChildCate”
icon=”append-child”
text=”⌘ + ⇧ + N 添加下级 cate ”
/>
<Divider type=”vertical” />
<mand=”customCollapse” icon=”collapse” text=”⌘ + B / Ctrl + B 折叠” />
<mand=”customExpand” icon=”expand” text=”⌘ + B / Ctrl + B 展开” />
</Toolbar>
);

export default MindToolbar;
