  openAlert(): void {
    this._dialogService.openAlert({
      message: 'This is how simple it is to create an alert with this wrapper service.',
      disableClose: true | false, // defaults to false
      viewContainerRef: this._viewContainerRef, //OPTIONAL

      width: '400px', //OPTIONAL, defaults to 400px
    });
  }

  openConfirm(): void {
    this._dialogService.openConfirm({
      message: 'This is how simple it is to create a confirm with this wrapper service. Do you agree?',
      disableClose: true | false, // defaults to false

    }).afterClosed().subscribe((accept: boolean) => {
      if (accept) {
        // DO SOMETHING
      } else {
        // DO SOMETHING ELSE
      }
    });
  }

  openPrompt(): void {
    this._dialogService.openPrompt({
      message: 'This is how simple it is to create a prompt with this wrapper service. Prompt something.',
      disableClose: true | false, // defaults to false
      viewContainerRef: this._viewContainerRef, //OPTIONAL
      title: 'Prompt', //OPTIONAL, hides if not provided
      value: 'Prepopulated value', //OPTIONAL

      if (newValue) {
        // DO SOMETHING
      } else {
        // DO SOMETHING ELSE
      }
    });
  }

  openDraggable(): void {
    this._dialogService.openDraggable({
      component: DraggableDemoComponent,
      config: { height: '300px' },
      // CSS selectors of element(s) inside the component meant to be drag handle(s)
      dragHandleSelectors: ['.drag-handle'],
      // Class that will be added to the component signifying drag-ability
      draggableClass: 'custom-class',
    });
  }
}
```

```typescript
import { Component } from '@angular/core';

@Component({
  selector: 'app-draggable-demo',
  template: `
    <h2>Draggable dialog</h2>
    <p>Draggable via the drag handle</p>
    <button mat-icon-button class="drag-handle">
      <mat-icon>drag_handle</mat-icon>
    </button>
  `,
})
export class DraggableDemoComponent {}
```

## Setup

Import the [CovalentDialogsModule] in your NgModule:

```typescript
import { CovalentDialogsModule } from '@covalent/core/dialogs';

@NgModule({
  imports: [
    CovalentDialogsModule,
    ...
  ],
  ...
})
export class MyModule {}
```

After that, just inject [TdDialogService] and use it for your dialogs.

# ResizableDraggableDialog

A utility to make a draggable dialog resizable.

## Usage

  ) {}
```

```ts
const {
  matDialogRef,
  dragRefSubject,
}: IDraggableRefs<DraggableResizableDialogComponent> = this._dialogService.openDraggable(
  {
    component: DraggableResizableDialogComponent,
    // CSS selectors of element(s) inside the component meant to be drag handle(s)
    dragHandleSelectors: ['.drag-handle'],
  }
);

let resizableDraggableDialog: ResizableDraggableDialog;
dragRefSubject.subscribe((dragRf: DragRef) => {
  resizableDraggableDialog = new ResizableDraggableDialog(
    this._document,
    this._renderer2,
    matDialogRef,
    dragRf
  );
});

// Detach resize-ability event listeners after dialog closes
matDialogRef.afterClosed().subscribe(() => resizableDraggableDialog.detach());
```
