How to enable swipe to next tab gesture for tabs module in Angular Material? (looking for a solution that works on more than 2 tabs)
I am using tabs component in angular material: https://material.angular.io/components/component/tabs
Is there a way to make it so that I can scroll to the content area of ââa tab to trigger the transition to the next tab?
My current html template:
<md-tab-group>
<md-tab label="Tab 1">Content 1</md-tab>
<md-tab label="Tab 2">Content 2</md-tab>
</md-tab-group>
I have imported hammerjs and the documentation doesn't seem to mention anything about it, although I could swear I've seen something like this before ...
Specifically, I want to be able to click and drag it to the left so that it will skip the left left tab. And click and drag the mouse to the right so that it slides to the right of the right tab.

here is a simple way to do it:
working plucker: https://plnkr.co/edit/uJ3n8XedvCCdeUHXKpwX?p=preview
first add hammerjs to your module:
import { HammerGestureConfig, HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';
indicate providers
providers: [{
provide: HAMMER_GESTURE_CONFIG,
useClass: HammerGestureConfig
}]
sample module:
@NgModule({
imports: [
BrowserModule,
BrowserAnimationsModule,
FormsModule,
ReactiveFormsModule,
MaterialModule,
],
declarations: [TabsOverviewExample],
bootstrap: [TabsOverviewExample],
providers: [{
provide: HAMMER_GESTURE_CONFIG,
useClass: HammerGestureConfig
}]
})
export class PlunkerAppModule {}
then create your component like this:
import {Component, AfterViewInit, ViewChild, ViewChildren} from '@angular/core';
import { MdTabGroup, MdTab } from '@angular/material';
@Component({
selector: 'tabs-overview-example',
template:`
<md-tab-group [selectedIndex]="selected" (swipeleft)="swipe($event.type)" (swiperight)="swipe($event.type)">
<md-tab label="Tab 1"><div class="content">Content 1</div></md-tab>
<md-tab label="Tab 2"><div class="content">Content 2</div></md-tab>
<md-tab label="Tab 3"><div class="content">Content 3</div></md-tab>
<md-tab label="Tab 4"><div class="content">Content 4</div></md-tab>
<md-tab label="Tab 5"><div class="content">Content 5</div></md-tab>
</md-tab-group>`,
styles:['.content{ height: 500px; background-color: yellow;}']
})
export class TabsOverviewExample implements AfterViewInit{
@ViewChild(MdTabGroup) group;
@ViewChildren(MdTab) tabs;
tab_num = 0;
selected = 0;
SWIPE_ACTION = { LEFT: 'swipeleft', RIGHT: 'swiperight' };
number_tabs
ngAfterViewInit(){
this.tab_num = this.tabs.length
console.log(this.group)
}
swipe(eType){
console.log(eType);
if(eType === this.SWIPE_ACTION.LEFT && this.selected > 0){
console.log("movin left")
this.selected--;
}
else if(eType === this.SWIPE_ACTION.RIGHT && this.selected < this.tab_num){
console.log("movin right")
this.selected++;
}
console.log(this.selected)
}
}

Template
<div class="md-content" flex md-scroll-y (swipeleft)="swipe(idx, $event.type)" (swiperight)="swipe(idx, $event.type)">
<md-tab-group md-stretch-tabs [(selectedIndex)]="selectedIndex" (selectedIndexChange)="selectChange()">
<md-tab label="Tab 1" (swipeleft)="swipe(1, $event.type)" (swiperight)="swipe(1, $event.type)">
Content 1
</md-tab>
<md-tab label="Tab 2" (swipeleft)="swipe(2, $event.type)" (swiperight)="swipe(2, $event.type)">Content 2</md-tab>
</md-tab-group>
</div>
component
export class TabsOverviewExample {
selectedIndex: number = 1;
selectChange(): void{
console.log("Selected INDEX: " + this.selectedIndex);
}
SWIPE_ACTION = { LEFT: 'swipeleft', RIGHT: 'swiperight' };
// Action triggered when user swipes
swipe(selectedIndex: number, action = this.SWIPE_ACTION.RIGHT) {
console.log("swipe");
console.log("number",selectedIndex);
console.log("action",action);
// Out of range
if (this.selectedIndex < 0 || this.selectedIndex > 1 ) return;
// Swipe left, next tab
if (action === this.SWIPE_ACTION.LEFT) {
const isLast = this.selectedIndex === 1;
this.selectedIndex = isLast ? 0 : this.selectedIndex + 1;
console.log("Swipe right - INDEX: " + this.selectedIndex);
}
// Swipe right, previous tab
if (action === this.SWIPE_ACTION.RIGHT) {
const isFirst = this.selectedIndex === 0;
this.selectedIndex = isFirst ? 1 : this.selectedIndex - 1;
console.log("Swipe left - INDEX: " + this.selectedIndex);
}
}
}
