resizable rectangle

[mrklev]

HI,
I need to create a draggable and resizable rectangle. Currently I can drag the rectangle but I can't resize it. How can I do it , which method should I use?

code:
html component:
<ko-stage #stage [config]="configStage">
<ko-layer #layer>
<ko-rect [config]="configRect"#rect >

ts component:
import { Component, ViewChild, OnInit } from '@angular/core';
import { of, Observable } from 'rxjs';
import { KonvaComponent } from 'ng2-konva';

@component({
selector: 'app-camera-img',
templateUrl: './camera-img.component.html',

})
export class CameraImgComponent implements OnInit {
@ViewChild('stage') stage: KonvaComponent;
@ViewChild('layer') layer: KonvaComponent;
@ViewChild('rect') rect: KonvaComponent;

public configStage: Observable = of({
width: 400,
height: 200
});

public configRect: Observable = of({
x: 160,
y: 60,
width: 100,
height: 90,
fill: 'red',
name: 'rect',
stroke: 'black',
draggable: true,
});

constructor(
private apiBackendService: ApiBackendService
) {
}
ngOnInit() {
}
}
