# [Content Type Dialog component](../../../lib/content-services/src/lib/content-type/content-type-dialog.component.ts "Defined in content-type-dialog.component.ts")
|
||||
|
||||
Confirm dialog when user changes content type of a node.
|
||||
|
||||
## Details
|
||||
|
||||
The [Content Type Dialog component](content-type-dialog.component.md) works as a dialog showing a confirm message when the user changes the conten type of a node. It is showing the properties of the new content type selected.
|
||||
|
||||
### Showing the dialog
|
||||
|
||||
Unlike most components, the [Content Type Dialog component](content-type-dialog.component.md) is typically shown in a dialog box
|
||||
rather than the main page and you are responsible for opening the dialog yourself. You can use the
|
||||
[Angular Material Dialog](https://material.angular.io/components/dialog/overview) for this,
|
||||
as shown in the usage example. ADF provides the [`ContentTypeDialogComponentData`](../../../lib/content-services/src/lib/content-type/content-type-metadata.interface.ts) interface
|
||||
to work with the Dialog's
|
||||
[data option](https://material.angular.io/components/dialog/overview#sharing-data-with-the-dialog-component-):
|
||||
|
||||
```ts
|
||||
export interface ContentTypeDialogComponentData {
|
||||
title: string;
|
||||
description: string;
|
||||
confirmMessage: string;
|
||||
select: Subject<boolean>;
|
||||
nodeType?: string;
|
||||
}
|
||||
```
|
||||
|
||||
The properties are described in the table below:
|
||||
|
||||
| Name | Type | Default value | Description |
|
||||
| ---- | ---- | ------------- | ----------- |
|
||||
| title | `string` | "" | Dialog title |
|
||||
| description | `string` | "" | Text to appear as description under the dialog title |
|
||||
| confirmMessage | `string` | "" | Text that will be showed on the top of properties list accordion |
|
||||
| select | [`Subject<Node>`](https://github.com/Alfresco/alfresco-js-api/blob/develop/src/api/content-rest-api/docs/Node.md) | | Event emitted when apply button is clicked |
|
||||
| nodeType | `string` | "" | current prefixed name of the content type selected |
|
||||
|
||||
If you don't want to manage the dialog yourself then it is easier to use the
|
||||
methods of the Content Type Property Service, which create
|
||||
the dialog for you.
|
||||
|
||||
### Usage example
|
||||
|
||||
```ts
|
||||
import { MatDialog } from '@angular/material/dialog';
|
||||
import { AspectListDialogComponentData, AspectListDialogComponent} from '@adf/content-services'
|
||||
import { Subject } from 'rxjs/Subject';
|
||||
...
|
||||
constructor(dialog: MatDialog ... ) {}
|
||||
openSelectorDialog() {
|
||||
const data: ContentTypeDialogComponentData = {
|
||||
title: 'CORE.METADATA.CONTENT_TYPE.DIALOG.TITLE',
|
||||
description: 'CORE.METADATA.CONTENT_TYPE.DIALOG.DESCRIPTION',
|
||||
confirmMessage: 'CORE.METADATA.CONTENT_TYPE.DIALOG.CONFIRM',
|
||||
select: select,
|
||||
nodeType
|
||||
};
|
||||
this.dialog.open(
|
||||
ContentTypeDialogComponent,
|
||||
{
|
||||
data, panelClass: 'adf-content-type-dialog',
|
||||
width: '630px'
|
||||
}
|
||||
);
|
||||
data.select.subscribe((selections: Node[]) => {
|
||||
// Use or store selection...
|
||||
},
|
||||
(error)=>{
|
||||
//your error handling
|
||||
},
|
||||
()=>{
|
||||
//action called when an action or cancel is clicked on the dialog
|
||||
this.dialog.closeAll();
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
All the results will be streamed to the select [subject](http://reactivex.io/rxjs/manual/overview.html#subject) present in the [`ContentTypeDialogData`](../../../lib/content-services/src/lib/content-type/content-type-metadata.interface.ts) object passed to the dialog.
|
||||
When the dialog action is selected by clicking, the `data.select` stream will be completed.
