How to enlarge Material-ui Rating icons

I am using npm to show develop a widget.
I want to use material-ui Ratin component and I have integrate it. But when I place the widget in a webpage, it has a html font-size: 62.5%, so the component is too small because in the icon style, there are a 1em unit in height and in width.
screenshot.
This is my code:
import React from 'react';
import Rating from '#material-ui/lab/Rating';
import Typography from '#material-ui/core/Typography';
import Box from '#material-ui/core/Box';
import { withStyles } from '#material-ui/core/styles';
import StarOutlineIcon from '#material-ui/icons/StarOutline';
const styles = theme => ({
iconFilled:{
color:theme.palette.primary.main,
},
iconEmpty:{
color:theme.palette.primary.main
}
})
class SimpleRating extends React.Component{
state = {
disabled: false,
rating: 0,
opinion: "",
};
changeRating(event, newRating) {
this.setState({
rating: newRating,
disabled: true
});
this.props.send_rating(newRating)
}
defaultLabelText(value) {
let text="sin calificación"
if (value===1){
text = "una estrella"
}
else if (value>1 && value<=5) {
text = ""+ value + " estrellas"
}
return(text)
}
render() {
const { classes } = this.props;
return (
<div>
<Box component="fieldset" mb={3} borderColor="transparent">
<Typography component="legend"></Typography>
<Rating
classes={{
iconFilled: classes.iconFilled,
iconEmpty: classes.iconEmpty
}}
emptyIcon = {<StarOutlineIcon></StarOutlineIcon>}
name={"rating_"+this.props.number}
disabled={this.state.disabled}
getLabelText={this.defaultLabelText.bind(this)}
onChange={this.changeRating.bind(this)}
value={this.state.rating}
/>
</Box>
</div>
);
}
}
export default withStyles(styles)(SimpleRating);
Althougth I have been able to change the color with the styles, I cannot modify that down.
How can I change that properties of the icon?
EDIT:
If i use the class icon in css i change the parent of the star icons while they continue with 1em x 1em size.
screenshot with changes in icon

To increase the size of the rating icons, we can use font-size. Using height and width will not work as it increases the size of the container they're in.
For example:
<Rating
name="rating"
value={starValue}
precision={0.1}
size="large"
readOnly
sx={{
fontSize: "4rem"
}}
/>
will increase the size of the icon further than just .MuiRating-sizeLarge which is their size if you set size="large". For reference, that size is about 1.8rem.

Have you tried to set the icon class of the rating component to a class which defines a new width and height?
const styles = theme => ({
iconFilled:{
color:theme.palette.primary.main,
},
iconEmpty:{
color:theme.palette.primary.main
},
//just some sample values
icon: {
width: 64,
height: 64
})
and then:
<Rating
classes={{
iconFilled: classes.iconFilled,
iconEmpty: classes.iconEmpty,
icon: classes.icon
}}
emptyIcon = {<StarOutlineIcon></StarOutlineIcon>}
name={"rating_"+this.props.number}
disabled={this.state.disabled}
getLabelText={this.defaultLabelText.bind(this)}
onChange={this.changeRating.bind(this)}
value={this.state.rating}
/>

Finally I solve it with this code because I was no able to enter to the icon itself:
icon = {<StarIcon style={{width:"32px",height:"32px"}}></StarIcon>}
emptyIcon = {<StarOutlineIcon style={{width:"32px",height:"32px"}}></StarOutlineIcon>}

Material-UI Override .MuiDataGrid-columnsContainer CSS

I am trying to override the CSS property position on the .MuiDataGrid-columnsContainer. When looking at the https://material-ui.com/api/data-grid/#css you can see there is a rule for root but there isn't a rule for .MuiDataGrid-columnsContainer. I have read the documentation on overriding the CSS properties but I can't seem to get it to work for that class.
Normally I would leverage the rule and do the following
const useStyles = makeStyles({
paper: {
background: '#010310',
}
});
Then return something like this
const classes = useStyles();
return (
<DataGrid classes={{ paper: classes.paper }} />
);
However, when I replace the word paper in the makeStyles and in the return to be columnsContainer it doesn't work.
Possible Reasons It's Not Working
Based on the documentation on the CSS for datagrid (link above), the only Rule is root and since the .MuiDataGrid-columnsContainer doesn't have a Rule then I need to do it differently. Unfortunately, I haven't found another way that has worked.
I appreciate any help I get, Thank you!

You can give inline style to the class that you want to override and give it an !important flag.
For example if the class you want to override is .MuiDataGrid-columnsContainer then you can simply do this .
.MuiDataGrid-columnsContainer{
position: relative !important; // to override the default css property
}

For a local overriding of MuiDataGrid-columnsContainer, as you can see on api doc, you have to pass your css to root class. So:
<DataGrid classes={{ root: classes.root }} />
Now if you want to override MuiDataGrid-columnsContainer in particular, in your makeStyles write something like:
const useStyles = makeStyles({
root: {
"&.MuiDataGrid-columnsContainer":{
background: '#010310',
}
}
});
Thats it.

root: {
"& .MuiDataGrid-root": {
color: `#fff`
},
"& .MuiIconButton-label": {
color: `#fff`
}
},
I put this "& .MuiDataGrid-root" in my main layout and it works very well.
const useStyles = makeStyles(() => ({
root: {
display: 'flex',
"& .MuiDataGrid-root": {
color: `#fff`
},
"& .MuiIconButton-label": {
color: `#fff`
}
},
appBar: {
backgroundColor:'#181745',
color:theme.palette.primary.main,
zIndex: theme.zIndex.drawer + 1,
transition: theme.transitions.create(['width', 'margin'], {
easing: theme.transitions.easing.sharp,
duration: theme.transitions.duration.leavingScreen,
}),
},
}))

How to custom color text and icon in TableSortText component of Material-ui?

What I'm trying to do:
I am trying to provide the user the option to provide custom styling to my EnhancedTable component by passing in a styles object containing properties such as headCellColor, headCellBackgroundColor, bodyCellColor, bodyCellBackgroundColor etc which can be used to color the cells in TableHead and TableBody.
In the TableHead component, I use a TableSortLabel in a way similar to what they've done in this material-ui docs example: https://material-ui.com/components/tables/#sorting-amp-selecting
I wish to custom color the text and the arrow icons on hover and when active based on the props provided by the user.
Let's see the colors of TableSortLabel in different situations:
The color of the text is grey initially and there is no arrow. When mouse is hovered over it, a grey arrow appears and the text turns black. On clicking it, active state is set, the grey arrow turns black and the text turns black permanently until active state is removed.
What I've tried so far:
const useStyles = makeStyles({
tableSortLabel: props => ({
backgroundColor: "blue",
color: props.headCellColor,
fill: props.headCellColor,
"&:hover": {
backgroundColor: "blue"
}
})
});
function EnhancedTableHeadCell(props) {
const { isActive, onHoverSortState, clickHandler, ...otherProps } = props;
const classes = useStyles(props.styles);
return (
<FancyTableCell styles={props.styles} {...otherProps}>
<TableSortLabel
active={isActive}
classes={{
icon: classes.tableSortLabel,
active: classes.tableSortLabel
}}
direction={onHoverSortState}
onClick={clickHandler}
>
{props.children}
</TableSortLabel>
</FancyTableCell>
);
}
This is what it looks like in the browser:
https://i.postimg.cc/fW7W2MRB/c1.jpg
The first one is a normal header, the second is on hover and the third is when clicked (active state).
From what we can observe, the text color is totally unaffected by the color css property in all the three cases (normal, hover, active). On hover, backgroundColor only affects the icon and not the text. However, we can see that backgroundColor affects the text when it is active. Everything is going as expected with the icon. The only issue is with the text.
What could I be possible doing wrong? How can I solve my problem?

What worked for me is:
const StyledTableSortLabel = withStyles((theme: Theme) =>
createStyles({
root: {
color: 'white',
"&:hover": {
color: 'white',
},
'&$active': {
color: 'white',
},
},
active: {},
icon: {
color: 'inherit !important'
},
})
)(TableSortLabel);
You can reference the following for increasing css specificity:
https://material-ui.com/customization/components/#pseudo-classes

Solution for your problem is following:
MuiTableSortLabel: {
root: {
color: textPrimary,
// if you want to have icons visible permanently
// '& $icon': {
// opacity: 1,
// color: primaryMain
// },
"&:hover": {
color: primaryMain,
'&& $icon': {
opacity: 1,
color: primaryMain
},
},
"&$active": {
color: primaryMain,
// && instead of & is a workaround for https://github.com/cssinjs/jss/issues/1045
'&& $icon': {
opacity: 1,
color: primaryMain
},
},
},
}
This restyling I use globally via my ThemeProvider, but you can of course use it individually in your single component by using "withStyles" HOC (see "BootstrapButton" in example)

I could'nt find a proper way to do it so I came up with a temporary solution overriding the material ui css.
I added this to my global css:
.MuiTableSortLabel-root.MuiTableSortLabel-active,
.MuiTableSortLabel-root:hover,
.MuiTableSortLabel-icon {
color: inherit !important;
}

Worked for me with Mui5:
sx = {
{
'&.MuiTableSortLabel-root': {
color: 'white',
},
'&.MuiTableSortLabel-root:hover': {
color: 'blue',
},
'&.Mui-active': {
color: 'blue',
},
'& .MuiTableSortLabel-icon': {
color: 'blue !important',
},
}
}
'&.MuiTableSortLabel-root' <-- no space &.
'&.Mui-active' <-- no space &.
'& .MuiTableSortLabel-icon' <-- space

another case when the state of a component changes but seems that the component does not

I have a react component that has a state variable:
showEditor
when showEditor is false it is supposed to show only a div with some number inside it (initially showEditor is false). If this state variable is true my react component is supposed to show a textbox and a button with "save" label inside another div -making dissapear the first div with the number-. This textbox will be used to change the number. For the first div (the one that only shows a number) I defined:
<div onClick={this.showEditorProc}>
{ this.state.showEditor ?
<div ....>
{ just the numeric value }
</div>
:
<div ....>
textBox
<button onClick={save and make show Editor false}>
Save
</button>
</div>
</div>
the function this.showEditorProc will modify the state of the showEditor variable to true and the save button and textbox components will appear (inside another div too). I created a function that will executed if the save button is clicked. This function modifies the showEditor variable to false however, I can not see the div with just the numeric value. Instead I still see the textbox with the save button. Is there something else I could be missing? Here it is the code of my component:
import React from 'react';
import ReactDOM from 'react-dom';
import NumberFormat from 'react-number-format';
export class NumericBox extends React.Component {
constructor() {
super();
this.state = {
enteredValue: '',
showNumEditor: false,
index: ''
};
this.showNumericEditor = this.showNumericEditor.bind(this);
this.handle_enteredValue_change = this.handle_enteredValue_change.bind(this);
this.saveCellInfo = this.saveCellInfo.bind(this);
this.loadBasicInformation = this.loadBasicInformation.bind(this);
}
saveCellInfo(e){
alert(this.state.index);
/* cellAuxParams = new Map([['updateCellValue', this.state.updateCellValue]]); */
console.log('numericBox.js>saveCellInfo>cellAuxParams= ------------------------------------------------ ' + 28);
console.log(this.props.cellAuxParams);
var f = this.props.cellAuxParams.get('updateCellValue');
this.setState({showNumEditor: false}, () => f(this.state.Index, '77'));
}
handle_enteredValue_change(values) {
const {formattedValue, value} = values;
// formattedValue = $2,223
// value ie, 2223
this.setState({enteredValue: value});
}
showNumericEditor()
{
this.setState({showNumEditor: true})
}
loadBasicInformation()
{
this.setState({enteredValue: this.props.enteredValue,
index: this.props.index
});
}
componentDidMount(){
this.loadBasicInformation();
}
componentWillReceiveProps(nextProps){
alert(nextProps.enteredValue);
this.setState({enteredValue: nextProps.enteredValue}, () => this.loadBasicInformation());
}
render() {
const table4controls = {
display: 'table',
width: this.props.style.width,
backgroundColor: 'white',
border: '0px solid #666666',
borderSpacing: '0px',
paddingBottom: '0em',
paddingTop: '0em'
};
const table4controls_RowStyle = {
display: 'table-row',
width: 'auto',
clear: 'both',
borderBottom: '5px'
};
const table4controls_ColsStyleA = {
float: 'left',
display: 'table-column',
width: '60px',
backgroundColor: 'white'
};
const table4controls_ColsStyleB = {
float: 'left',
display: 'table-column',
width: '20px',
backgroundColor: 'white'
};
const table4controls_ColsStyleC = {
float: 'left',
display: 'table-column',
width: '20px',
backgroundColor: 'white'
};
const btnStyle={
};
return (
<div onClick={this.showNumericEditor}>
{ this.state.showNumEditor ?
<div style ={table4controls}>
<div style={table4controls_RowStyle}>
<div style={table4controls_ColsStyleA}>
<NumberFormat style={{width: '60px'}}
value={this.state.enteredValue}
thousandSeparator={true}
prefix={this.props.prefix}
onValueChange={this.handle_enteredValue_change}
/>
</div>
<div style={table4controls_ColsStyleB}>
<button style={btnStyle} onClick={() => this.saveCellInfo(this.state.index)}>
▲
</button>
<button style={btnStyle} onClick={() => this.saveCellInfo(this.state.index)}>
▼
</button>
</div>
<div style={table4controls_ColsStyleC}>
<button style={btnStyle} onClick={(e) => {this.saveCellInfo(e, this.state.index)}}>
Save
</button>
</div>
</div>
</div>
:
<div syle={table4controls_ColsStyleA}>
{this.state.enteredValue}
</div>
}
</div>
);
}
}

You have an onClick={this.showNumericEditor} handler on the surrounding div, so when you press the save button, the click event bubbles up and invokes a this.setState({showNumEditor: true}).
To fix it, you can either restructure the rendering or call e.stopPropagation(); at the start of saveCellInfo. Also note that some of your this.saveCellInfo calls are not passing the event.

How to align text in Draft.js

I'm wondering how to align text in Draft.js just like on the picture below.
I have searched this several days, but I haven't found the solution.

After reading the source code, I found a way for it. Using blockRenderMap, you can add some custom block types like this:
const blockRenderMap: Record<string, DraftBlockRenderConfig> = {
'header-one-right': {
element: 'h1',
wrapper: <StyleHOC style={{ ...blockStylesMap['header-one'], display: 'flex', justifyContent: 'flex-end' }} />,
},
'header-two-right': {
element: 'h2',
wrapper: <StyleHOC style={{ ...blockStylesMap['header-two'], display: 'flex', justifyContent: 'flex-end' }} />,
},
'header-three-right': {
element: 'h3',
wrapper: <StyleHOC style={{ ...blockStylesMap['header-three'], display: 'flex', justifyContent: 'flex-end' }} />,
},
'unstyled-right': {
element: 'div',
wrapper: <StyleHOC style={{ ...blockStylesMap['unstyled'], display: 'flex', justifyContent: 'flex-end' }} />,
},
};
I use flex to avoid wasting time to find a away to override the internal style .public-DraftStyleDefault-ltr.
StyleHOC is quite simple:
const StyleHOC: React.FC<Props> = ({ style, children }) => {
const childrenWithStyle = React.Children.map(children, (child) => {
if (React.isValidElement(child)) {
return React.cloneElement(child, { style });
}
return child;
});
return <>{childrenWithStyle}</>;
};
And then you can toggle the blockType using RichUtils.toggleBlockType(editorState, blockType).

The Editor component has a div with the class .public-DraftStyleDefault-ltr. This controls the text alignment of each paragraph that you write. As you create more paragraphs, more of these divs are created to contain the text. The text is wrapped in a span element and .public-DraftStyleDefault-ltr has a default alignment of text-align: left.
I created some css classes for text-align: left, text-align: center, text-align: right and text-align: justify and added this basic for loop to my component for creating text alignment buttons.
const textBlock = document.querySelectorAll(".public-DraftStyleDefault-ltr");
for (let i = 0; i < textBlock.length; i++) {
textBlock[i].classList.toggle(this.props.style);
}
this.props.style is the name of the css class that determines the text-alignment I wanted.
It is a pretty basic fix since this way when you click align right say, the whole document is aligned right. I am planning to work on this so only the selected text is aligned so should be able to update this answer soon. Hope it helps in some way

I tried to make almost the same thing. But my trouble was in text-align property, which was correctly set to block span, but .public-DraftStyleDefault-ltr doesn't react to it.
So, I have made next decision, which get the first div child, and copy it's params:
const paragraphs: any = document.querySelectorAll(".public-DraftStyleDefault-ltr");
for (let i = 0; i < paragraphs.length; i++) {
const paragraph = paragraphs.item(i);
if (paragraph) {
const firstItem = paragraph.querySelectorAll('*').item(0);
// Apply to the parent the first child style
paragraph.style.textAlign = firstItem.style.textAlign;
}
}

To change block alignment you can:
1- set alignment data
const modifiedBlockState = Modifier.setBlockData(editorState.getCurrentContent(),
editorState.getSelection(),Map({align:'align-center'}));
setEditorState(EditorState.push(modifiedBlockState,'change-block-data'));
2- use it in styling function
/*
JSX
blockStyleFn={ block => block.getData().get('align')
this will return 'align-center|left|right' which will be assigned as a classname
*/
<Editor blockStyleFn={ block => block.getData().get('align')} .../>
//CSS
.align-center div{
text-align: center;
}
.align-right div{
text-align: right;
}
.....
