I have been wasted hours and days trying to style the Vaadin Upload component. The goal is simple:
sometimes I need the component to show the uploaded file using its built-in file list with allows delete.
other times, I want to hide this list because I have another component such as Grid to show the file details.
Now comes the problem, I can never get it to consistently work using #CssImport with themeFor=vaadin-upload and themeFor=vaadin-upload-file. Vaadin seems to compile the shadow dom and the final result varies, it mixes up the two options and whichever comes last gets applied.
I then thought maybe because the #CssImport is in the #Route component. So, I created two custom upload components that extended the vaadin-upload component with the difference being the different #CssImport (see below). That (frustratingly) still doesn't work. I inspect the document and found that the inside the shadow-dom contains both even though I never use both on the same page.
#CssImport(value = "./css/vaadin-upload-show.css", themeFor = "vaadin-upload")
public class UploadShowFiles extends Upload {
private static final long serialVersionUID = -9198630843136885092L;
public UploadShowFiles(Receiver receiver) {
super(receiver);
}
}
#CssImport(value = "./css/vaadin-upload-hidefile.css", themeFor = "vaadin-upload")
public class UploadHideFiles extends Upload {
private static final long serialVersionUID = 2344860066834705807L;
public UploadHideFiles(Receiver receiver) {
super(receiver);
setClassName("hide-upload");
}
}
The css below will appear in the shadow dom. I expect only display: none or otherwise, not both.
[name="file-list"] {
display: none !important;
height: 0px !important;
}
[name="file-list"] div[part="file-list"] {
display: none !important;
}
[name="file-list"] {
display: block !important;
height: 1.5rem !important;
}
[name="file-list"] div[part="file-list"] {
display: block !important;
}
p/s: This is my first experience using Vaadin in a project and I probably never going to use it again. Customizing anything in Vaadin is so time-consuming and painful.
Styling in the shadow DOM can indeed be tricky. The simplified theming in Vaadin 19 helps a bit.
Where the #CssImport annotation is placed affects if the CSS should be included in the document, but not which components it affects. With themeFor, it will always be applied to all matching components.
What you can do is to use the :host selector to limit which upload components it applies to. Here I am using a class-based approach:
:host(.no-file-list) [name="file-list"] {
display: none !important;
height: 0px !important;
}
:host(.no-file-list) [name="file-list"] div[part="file-list"] {
display: none !important;
}
I can then hide the file list in an upload component by adding a class:
#Route
#CssImport(value = "./styles/upload-style.css", themeFor = "vaadin-upload")
public class FileUploadTest extends VerticalLayout {
public FileUploadTest() {
Upload uploadWithFileList = new Upload();
Upload uploadWithoutFileList = new Upload();
uploadWithoutFileList.addClassName("no-file-list");
add(uploadWithFileList, uploadWithoutFileList);
}
}
I'm trying to customize mat-select with multiple checkboxes.
for some reason the panel get wrong min-width as below:
and I don't know where its calculating this min-width.
also I tried to add panelClass and override the min-width from this class,
for example:
<mat-select #multipleSelect (selectionChange)="selectItem($event.value)" panelClass="multiple-panel" multiple>
&.multiple-panel {
min-width: 200px !important;
}
but when opening the dropdown its open with the original width (like in the pic) and after few millisecond"jump" to the custom min-width defined on the panel class.
I find the mat-select very hard to style. anybody knows how to solve this problem?
You can style your mat-select dialog box by giving a panel class (as you mentioned).
Please follow this demo : https://stackblitz.com/edit/angular-matselect-style?file=src/styles.css
to see the styled mat-select components.
Reason :
Reason for the delay is that angular for dialog-boxes, create a cdk-overlay-pane inside the cdk-overlay-container container, So in case of mat-select it provides a min-width of 180px, which is overridden by our panel class in the slight delay.
Yes, there is a slight delay in opening of dialog box and customizing its width to the specified width provided in the panel class. But the delay is acceptable in the project that i was working on. So, you can find the demo for styling the mat-select component, as i have provided 2 components and you can modify any css properties.
Try to use styles using ::ng-deep or :host >>>, if not finding any luck, please paste the styles in style.css.
Update 1 :
Tried css animations, and opacity for making smooth opening of the mat-select options.
.panel-class-applied-on-mat-select {
animation-name: opacityDelay !important;
animation-duration: 0.3s !important;
}
#keyframes opacityDelay {
0% {opacity: 0;}
25% {opacity: 0;}
50% {opacity: 0;}
75% {opacity: 0;}
100% {opacity: 1;}
}
Updated StackBlitz Demo
I used another approach.
Just added this piece of code to global style.
.mat-select-panel {
// some your code
&.ng-animating {
visibility: hidden;
}
}
You can try this solution on
DEMO StackBlitz.
Hack with opacity did not fix jumping width when select is closing.
You'll need to change viewEncapsulation to none at your component decorator.and then add following css to remove the transition effect.Have a look at viewencapsulation in angular docs https://angular.io/guide/component-styles#view-encapsulation.
#Component({
selector: 'app-selector',
templateUrl: './template.html',
styleUrls: ['./template.css'],
encapsulation: ViewEncapsulation.None
})
//CSS
.cdk-overlay-connected-position-bounding-box .cdk-overlay-pane .mat-select-panel.ng-animating {
display: none;
}
Try this way : define a panel class for your mat-select in the code and then in the global/app styling file just add:
.panel-class-name .mat-select-panel {
// add your styling here
}
It worked for me to add some component specific styling for material components.
Please go easy on me S.O. This is my first time contributing. :)
After debugging the console, and running into this issue. Solutions were not clear online. So I'm posting mine here in case someone else runs into this.
I found that there is a width permanently set for the infix class. If you unset it, and optionally add some padding to the right of the value, you'll find that will resolve the issue. Add :host for encapsulation when using ::ng-deep.
Important to Note: ::ng-deep is being permanently deprecated after Angular v14.
There is a property in the #Component() annotation called encapsulation which can be used to turn off the view encapsulation for the component instead of using ::ng-deep.
Solution for the deprecation of ::ng-deep:
#Component({
selector: 'app-selector-name',
template: `<div>Hello World!</div>`,
encapsulation: ViewEncapsulation.None,
styles: [
`
:host mat-form-field .mat-form-field-infix {
width: unset;
}
:host mat-form-field .mat-select-value {
padding-right: 0.5rem; /* 8px */
/* Alternatively, for TailwindCSS: #apply pr-2 */
}
:host .random-class {
/* some encapsulated styling... */
}
.another-random-class {
/* some non-encapsulated styling... */
}
`
]
})
Solution if you do not care about the deprecation of ::ng-deep:
:host ::ng-deep mat-form-field .mat-form-field-infix {
width: unset;
}
:host ::ng-deep mat-form-field .mat-select-value {
padding-right: 0.5rem; /* 8px */
}
I'm using checkbox of angular-material2. Currently the default color of checkbox is coming as purple color.
Looks like they have changed default color of checkbox from "primary" to accent.
Is there a way to get "primary"(green) color instead of purple without overriding css.
I tried giving color="primary" to but that didn't worked.
Code : <md-checkbox></md-checkbox>
Import statement:
import {MdCheckbox} from '#angular2-material/checkbox';
Plunker http://plnkr.co/edit/sFC0kfdzj7fxtUC3GXdr?p=preview
Based on feedback from comments, updated my answer by removing '::ng-deep', but please read comment by #colin-fox, and understand how this will behave in global styling and at component level, many thanks!
For Angular Material 7, works for outline color and inside filled in color
.mat-checkbox-checked.mat-accent .mat-checkbox-ripple .mat-ripple-element {
opacity: 0.03 !important;
background-color: #005691!important;
}
.mat-checkbox-checked.mat-accent .mat-checkbox-background,.mat-checkbox-indeterminate.mat-accent .mat-checkbox-background {
background-color: #005691;
}
You don't have to add css if you'r using theme, just add attribute color to <mat-checkbox>
<mat-checkbox color="primary">Primary</mat-checkbox>
The color of a <mat-checkbox> can be changed by using the color property. By default, checkboxes use the theme's accent color. This can be changed to 'primary' or 'warn'
Checkbox | Angular Material
One of the standard ways to do this is to utilize the /deep/ selector
mat-checkbox {
color: rgb(0,178,0);
/deep/ .mat-checkbox-background {
background-color: rgb(0,178,0);
}
/deep/ &.mat-checkbox-focused{
.mat-ink-ripple{
background-color: rgba(0, 178, 0, .26);
}
}
}
That will allow you to override styles in components where Shadow Dom is enabled.
This solution works well for me
.mat-checkbox-ripple .mat-ripple-element,
.mat-checkbox-checked.mat-accent .mat-checkbox-background {
background-color: $your-color !important;
}
Default color depends upon the theme which you #import.
But angular material also provide way to customize the theme or for customizing the components like changing the color of checkbox.
Steps of doing this as follow :-
1.) Import the _theming.scss file
#import "../node_modules/#angular/material/theming";
2.) Specify the accent color i.e. color of check box you want to apply like below :-
// customising of the mat-checkbox accordiing Theme. i am using pink indigo theme
bydefault so here I am changing the checkbox color from pink to grey.
$candy-app-primary: mat-palette($mat-indigo);
// here I am specify the grey instead of Pink.
$candy-app-accent: mat-palette($mat-grey, 600, 500, 900);
$candy-app-warn: mat-palette($mat-red);
// Create the theme object (a Sass map containing all of the palettes).
$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);
// here I am only calling checkbox mixin because i only want to change the checkbox color
#include mat-checkbox-theme($candy-app-theme);
Hope it will help.
Angular 7+
This will work for checkbox as well as the initial ripple color. If you just change the background for the checkbox, the initial ripple color won't update. This resolves the issue.
SCSS:
::ng-deep .mat-checkbox-checked.mat-accent {
.mat-checkbox-ripple .mat-ripple-element {
background-color: $your-color !important;
}
.mat-checkbox-background, .mat-checkbox-indeterminate.mat-accent .mat-checkbox-background {
background-color: $your-color;
}
}
::ng-deep .mat-checkbox.mat-accent {
.mat-checkbox-ripple .mat-ripple-element {
background-color: $your-color !important;
}
}
A combination of answers worked for me in angular 9
.mat-checkbox-checked.mat-accent .mat-checkbox-ripple .mat-ripple-element {
opacity: 0.03 !important;
background-color: #005691 !important;
}
.mat-checkbox-checked.mat-accent .mat-checkbox-background,
.mat-checkbox-indeterminate.mat-accent .mat-checkbox-background {
background-color: #005691 !important;
}
.mat-checkbox-ripple .mat-ripple-element,
.mat-checkbox-checked.mat-accent .mat-checkbox-background {
background-color: #005691 !important;
}
With beta.2 of Angular Material, the color attribute should work.
There were some issues with it before beta.2
See the commit that fixed that issue.
There are two methods(that i know ) to change the background color of mat-checkbox (angular 9)-
method 1 - by using color property of the mat-checkbox .
<mat-checkbox
id="{{ subtask.name }}"
[color]="accent"
>
Check
</mat-checkbox>
Limitation - You can only use color according to the angular material theme by this method .
method 2 - If you want to give custom colors to the mat-checkbox first track down the classes till the target class you want to change color of. tracking of nested classes
after that write like this in your style.css(global) file-
1st checkbox
.l0
.mat-checkbox-checked
.mat-checkbox-layout
.mat-checkbox-inner-container
.mat-checkbox-background {
background-color: #ffbf00 !important;
}
2nd checkbox
.l1
.mat-checkbox-checked
.mat-checkbox-layout
.mat-checkbox-inner-container
.mat-checkbox-background {
background-color: #4caf50 !important;
}
Result - different color for different mat-checkbox
This should take care of the default checkbox color
md-checkbox .md-icon {
background: green;
}
md-checkbox.md-default-theme.md-checked .md-icon {
background: green;
}
read more here at Angular Material Documentation
The following will keep frame grey when unchecked but change to custom color when checked:
relevant-scss-file.scss
mat-checkbox {
&.mat-checkbox-disabled.mat-checkbox-checked .mat-checkbox-background {
background: rgb(0,178,0);
}
}
Since deep is deprecated. In my view the right way to do it is using encapsulation: ViewEncapsulation.None.
ex:
#Component({
selector: '...',
templateUrl: '...',
styleUrls: ['...'],
encapsulation: ViewEncapsulation.None,
})
Then you just need to change the class
.mat-checkbox-background {
background-color: green;
}
You just need to be careful to deal with global css stuff. In SASS nested classes should handle it properly.
You can have more details here: https://stackoverflow.com/a/54672579/783364
For me what has worked is the following:
<mat-checkbox class="tn-checkbox">Check me!</mat-checkbox>
In the css (or in my case sass):
.#{$wf__ns}checkbox {
.mat-checkbox-ripple {
.mat-ripple-element {
background: $cool-blue !important;
}
}
&.mat-checkbox-checked {
.mat-checkbox-background {
background: $cool-blue;
}
.mat-checkbox-ripple {
.mat-ripple-element {
background: $cool-blue !important;
}
}
}
}
Explanation:
The checked background color is changed to mat-checkbox-background within mat-checkbox-checked. IF you want to modify the background color when it is not checked just copy that part and copy it outside of mat-checkbox-checked.
As for the ripple classes, it turns out that the material has an animation when you press the button. That class controls the color of the animation, if you don't change it it will remain the same (pink).
If you do not change it by pressing the checkbox you will see a strange pink effect.
The other answers do not work for me although I rely on the first to develop it.
It may be from my version of angular that I leave below:
Angular CLI: 8.3.25
Node: 13.3.0
Angular: 8.2.14
You can change the color of the border this way.(angular)
::ng-deep .mat-checkbox {
.mat-checkbox-ripple .mat-ripple-element {
background-color: #07abe9 !important;
}
.mat-checkbox-frame {
border-color: #07abe9 !important;
}
}
This worked for me with Angular 10:
In your styles.scss:
//Change background color
.mat-checkbox-checked.mat-accent .mat-checkbox-background,
.mat-checkbox-indeterminate.mat-accent .mat-checkbox-background {
background-color: #1f45cc;
}
//Change the border color for both checked and unchecked cases
.mat-checkbox-frame {
border-color: #1f45cc;
}
.mat-checkbox-ripple .mat-ripple-element,.mat-checkbox-checked.mat-accent .mat-checkbox-background {
background-color: $your-color!important;
}
.mat-checkbox-checked.mat-primary .mat-checkbox-background, .mat-checkbox-indeterminate.mat-primary .mat-checkbox-background{
background-color: $your-color!important;
}
This is what works. On our JHIPSTER project, we have a global.scss. Here is what you need to do if you do have a global.
Wrap your component html with a class. Forexample:
<div class="supplier-details-container">
<!-- rest of your html here -->
</div>
In the global.scss or global.css write your css/scss like so (Im using red to test):
.supplier-details-container .mat-checkbox-ripple .mat-ripple-element,.mat-checkbox-checked.mat-accent .mat-checkbox-background {
background-color: red !important;
}
Basically using css hierarchy wrapping the native angular material css with your component class that you use to wrap your component html.
Let me know if it works or not. We can debug.
Update for Angular Material 15:
.mat-mdc-checkbox.mat-mdc-checkbox-checked .mdc-checkbox__background, .mdc-checkbox__ripple {
background-color: green !important;
border-color: green !important;
}
this solution works well for me
/deep/.mat-checkbox-checked.mat-accent .mat-checkbox-background, .mat-checkbox-indeterminate.mat-accent .mat-checkbox-background {
background-color: #3490d3;
}
I am new to vaadin. I have one button it should look like a link. I have created button like,
Button title = new Button(item.getSubmissionTitle());
title.setStyleName(BaseTheme.BUTTON_LINK);
I also tried using
title.setStyleName("link);
but still I am getting look and feel of button. Is there any way to change the button using css Or any alternative ways by wich the button should appear as a link.
EDIT
I just found out The button is getting css from Table. And overriding the button style.
For table, it has written
table.setDebugId("submissionsTable_id");
css for button in table is:
#submissionsTable_id .v-table-cell-wrapper .v-button-caption{white-space:normal !important;text-decoration:none;}
#submissionsTable_id .submission-content{width:350px;}
#submissionsTable_id .v-table-cell-wrapper .v-button-caption:hover
{
background:#3F1A7D;
color: #FFFFFF;
}
#submissionsTable_id .v-button-caption:hover
{
background:#3F1A7D;
color: #FFFFFF;
}
Now, How can i exclude my Link button to override the table's style or how can I add new style to button which should not inherit the style of the table.
A future reference for anyone else with this issue. According to the Book of Vaadin online:
https://vaadin.com/book/vaadin7/-/page/components.button.html#figure.component.button.basic
Some built-in themes contain a small style, which you can enable by adding Reindeer.BUTTON_SMALL, etc. The BaseTheme also has a BUTTON_LINK style, which makes the button look like a hyperlink.
If you are using the Reindeer theme the code would be:
title.setStyleName(Reindeer.BUTTON_LINK);
Apparently resetting styles for a particular element is not possible, according to this post. You have to selectively overwrite the css properties for that element in order to simulate the aspect of a link.
If it's any help, the following is some CSS I scrounged up that simulates to some degree the look and behaviour of a link:
a:link {
color: #0000FF;
background-color:#FFF;
text-decoration:underline;
}
a:visited {
color: #800080;
background-color:#FFF;
text-decoration:underline;
}
a:hover {
color: #0000FF;
background-color:#FFF;
text-decoration:none;
}
a:active {
color: #FF0000;
background-color:#FFF;
text-decoration:none;
}
Note that the default look and behavior of a vanilla link depends on the browser its viewed in.
No need to play with the Button; there is a Link component for this.
#Override
protected void init(VaadinRequest vaadinRequest) {
HorizontalLayout layout = new HorizontalLayout();
Link link = new Link("Go to stackoverflow.com",
new ExternalResource("https://stackoverflow.com/"));
layout.setMargin(true);
layout.addComponents(link);
setContent(layout);
}
Pixate seems to be unable to style UISearchBar's UITextField. Neither the text, corner radius etc. is styled, no matter how broadly I select text-field.
Also, there is an annoying dark hairline at the top and bottom of the UISearchBar as soon as I try to style it (e.g. give it a background color) using Pixate.
Furthermore, the cancel button label suddenly has white text and I found no way to overwrite it to any other color.
So the question is: Am I missing something or does Pixate in fact not support this (yet)?
What I want it to look like:
What it looks like using Pixate.
The stylesheet:
table-view {
separator-style: single-line;
separator-color: #eeeeee;
background-color: #eeeeee;
}
table-view-cell {
background-color: white;
}
search-bar {
background-color: #eeeeee;
}
Treat it like you would a normal CSS selector.
search-bar button {
color: white;
}
