Using MatToolTip with icons in Angular 5
Solution 1
Just use the official material icon element:
<mat-icon matTooltip="My tooltip">delete</mat-icon>
You can of course style it however you want, enclose it in a div and give that div a class, add event listeners, etc.
Solution 2
For anyone stuck with tooltips not working, please double-check your app.module.ts file. Make sure that your imports: [...]
array includes MatTooltipModule
, and that you are importing MatTooltipModule with the other imports.
If you don't include these things, tooltips simply won't work, yet there will also be no errors in the console.
I got stuck wondering why my <mat-icon matTooltip="test">warning</mat-icon>
wasn't working, turns out this is why.
Solution 3
For anyone looking to bind variable to matTooltip
, you need to bind it using expression [matTooltip]
so it will look something like this:
<mat-icon class='colorInfo' [matTooltip]="tooltipVariable">info_outline</mat-icon>

I am able to use
MatToolTip
along with a button element:<button mat-mini-fab color="primary" (click)="fn()"> <span matTooltip="myMessage"> <i class="material-icons">delete</i> </span> </button>
But on trying to use it with an icon which is within a
div
orspan
tag, it doesn't work:<div matToolTip="myMessage"> <i style="line-height: 0px; font-size: 25px; cursor: pointer; " (click)="fn()" class="material-icons">delete</i> </div>
What am I doing wrong?
