import { Component, OnInit } from '@angular/core';
import { of } from 'rxjs';
import { NgWizardConfig, NgWizardService, StepChangedArgs, StepValidationArgs, STEP_STATE, THEME } from 'ng-wizard-v2';

@Component({
templateUrl: 'app.component.html'
})
export class AppComponent implements OnInit {
stepStates = {
normal: STEP_STATE.normal,
disabled: STEP_STATE.disabled,
error: STEP_STATE.error,
hidden: STEP_STATE.hidden
};

config: NgWizardConfig = {
selected: 0,
theme: THEME.arrows,
toolbarSettings: {
toolbarExtraButtons: [
{ text: 'Finish', class: 'btn btn-info', event: () => { alert("Finished!!!"); } }
],
}
};

constructor(private ngWizardService: NgWizardService) {
}

ngOnInit() {
}

showPreviousStep(event?: Event) {
this.ngWizardService.previous();
}

showNextStep(event?: Event) {
this.ngWizardService.next();
}

resetWizard(event?: Event) {
this.ngWizardService.reset();
}

setTheme(theme: THEME) {
this.ngWizardService.theme(theme);
}

stepChanged(args: StepChangedArgs) {
console.log(args.step);
}

isValidTypeBoolean: boolean = true;

isValidFunctionReturnsBoolean(args: StepValidationArgs) {
return true;
}

isValidFunctionReturnsObservable(args: StepValidationArgs) {
return of(true);
}
}
