How to enlarge the SVG icon in material-ui iconButtons?
提问by Jun Yin
Has anyone build webpages using react.jsand the Material UIlibrary? How should I resize the icon size? It is a svg icon. I just built an "create new" component, which is a piece of material paper with a content add button on the top. Here is the code.
有没有人使用react.js和Material UI库构建网页？我应该如何调整图标大小？它是一个 svg 图标。我刚刚构建了一个“创建新”组件，它是一张材料纸，顶部有一个内容添加按钮。这是代码。
import React from 'react';
import Paper from 'material-ui/lib/paper';
import ContentAdd from 'material-ui/lib/svg-icons/content/add';
import IconButton from 'material-ui/lib/icon-button';
const styleForPaper = {
width: '96vw',
height: '20vh',
margin: 20,
textAlign: 'center',
display: 'inline-block',
};
const styleForButton = {
'marginTop': '7vh',
};
const PaperToAddNewWidgets = () => (
<div>
<Paper style={styleForPaper} zDepth={2}>
<IconButton
style={styleForButton}
touch={true}
tooltip="Add New Widget">
<ContentAdd/>
</IconButton>
</Paper>
</div>
);
export default PaperToAddNewWidgets;It looks OK (make sure you are viewing it at full size), but the icon is too small. Then I opened the chrome dev tool, and saw the following html code.
它看起来不错（确保您以全尺寸查看），但图标太小。然后我打开chrome dev工具，看到如下html代码。

But I am not sure how I can resize the icon size in my code. If I write a CSS file to revise the svg it will be problematic if there are more than one svg elements.
使用 chrome dev 工具，我修改了 svg 图标大小和 svg 的 viewbox 属性，并使浏览器中的图标更大。但我不确定如何在我的代码中调整图标大小。如果我编写一个 CSS 文件来修改 svg，那么如果有多个 svg 元素就会出现问题。

You have to set the size of the icon in the iconStyleprop in <IconButton>. Example below from the material-ui docs.
您必须在iconStyle.properties 中设置图标的大小<IconButton>。以下示例来自 material-ui 文档。
From my experience, if you set just the height or the width, nothing happens--only seems to work when you set height & width to the same value.
根据我的经验，如果您只设置高度或宽度，则什么也不会发生——只有当您将高度和宽度设置为相同的值时，它才会起作用。
import React from 'react';
import IconButton from 'material-ui/IconButton';
import ActionHome from 'material-ui/svg-icons/action/home';
const styles = {
largeIcon: {
width: 60,
height: 60,
},
};
const IconButtonExampleSize = () => (
<div>
<IconButton
iconStyle={styles.largeIcon}
>
<ActionHome />
</IconButton>
</div>
);

With the latest version of material-ui (3.1.0), you can change padding of IconButton and fontSize of SvgIcon to update the looks.
使用最新版本的 material-ui (3.1.0)，您可以更改 IconButton 的 padding 和 SvgIcon 的 fontSize 以更新外观。
const styles = theme => ({
smallButton: {
padding: 6
},
largeButton: {
padding: 24
},
largeIcon: {
fontSize: "3em"
},
input: {
display: "none"
}
});
function IconButtons(props) {
const { classes } = props;
return (
<div>
<IconButton className={classes.smallButton} aria-label="Delete">
<DeleteIcon fontSize="small" />
</IconButton>
<IconButton aria-label="Delete">
<DeleteIcon fontSize="large" />
</IconButton>
<IconButton className={classes.largeButton} aria-label="Delete">
<DeleteIcon className={classes.largeIcon} />
</IconButton>
</div>
);
}

I faced the same issue while using the last React version (which is today v16.13.1) and Material-ui (which is today v4.9.14).
我在使用上一个 React 版本（今天是 v16.13.1）和 Material-ui（今天是 v4.9.14）时遇到了同样的问题。

By simply adding this style to the icon button
只需将此样式添加到图标按钮
MyIconButton: {
'& svg': {
fontSize: theSizeIWant
}
}
Complete example
完整示例
import React from "react";
import { makeStyles } from '@material-ui/core/styles';
import IconButton from '@material-ui/core/IconButton';
import DeleteIcon from '@material-ui/icons/Delete';
const useStyles = makeStyles((theme) => ({
deleteIcon1: {
'& svg': {
fontSize: 25
}
},
deleteIcon2: {
'& svg': {
fontSize: 50
}
},
deleteIcon3: {

I am using IconStyle prop to change the size of svg icon.
我正在使用 IconStyle 道具来更改 svg 图标的大小。
<IconButton
tooltip="Add New Group"
tooltipPosition="top-center"
style={{padding: 0, height: 0}}
iconStyle={{height: 31, width: 48}}
onClick={e => this.openNewList()}
disabled={!this.state.newAvailable}>
<ActionHome />
</IconButton>

There are two ways of enlarging the svg, one is to override the style with iconStyle, the other is to edit the code found in https://github.com/callemall/material-ui/blob/master/src/SvgIcon/SvgIcon.js
svg 的放大有两种方式，一种是用 iconStyle 覆盖样式，另一种是编辑https://github.com/callemall/material-ui/blob/master/src/SvgIcon/SvgIcon 中的代码.js
Note: ContentAddimports from SvgIcon
注：ContentAdd进口自SvgIcon
const mergedStyles = Object.assign({
..
height: 24, // <-- change default height
width: 24, // <-- change default width
..
}, style);
return (
<svg
{...other}
..
style={prepareStyles(mergedStyles)}
..
