The onNodeContextMenuSelect function does not seem to be functioning properly within the p-tree

<p-tree
  [value]="files"
  selectionMode="single"
  (onNodeContextMenuSelect)="showContect($event)"
>
</p-tree>

Whenever I right click, the event doesn't seem to be triggering. Instead, the default browser context menu pops up.

The expected behavior is to call the showContect function.

Answer №1

To customize the context menu options in your web page, you must include a Context Menu instance in your HTML code.
With the Context Menu, you can handle events using the command specified in the items array or utilize onNodeContextMenuSelect.
For a demonstration, refer to this example: here

Add the following lines to your .html file:

<p-tree
  [value]="files"
  selectionMode="single"
  [contextMenu]="cm"
  (onNodeContextMenuSelect)=showContect($event)
>
</p-tree>

<p-contextMenu
  #cm
  [model]="items"
>
</p-contextMenu>

Include these lines in your .ts file:

ngOnInit() {
  this.items = [
    {
      label: 'View',
      icon: 'pi pi-search',
      command: (event) => this.viewFile(this.selectedFile),
    },
    {
      label: 'Unselect',
      icon: 'pi pi-times',
      command: (event) => this.unselectFile(),
    },
  ];
}

showContect(event: any) {
  console.log(event.node);
}

Answer №2

It's recommended to utilize the contextmenu event instead of onNodeContextMenuSelect by adding it to the p-tree component

 <p-tree
  [value]="files"
  selectionMode="single"
  (contexmenu)="showContect($event)"
>
</p-tree>
showContect(event){
 event.preventDefault();

 console.log('called!')
}
