NgxPropertyGrid

A small and simple property grid in angular to view/edit POJOs, excellent if you have a "settings" object you want to give the user to edit (that's why I have created it). Play online.

Dependencies

• angular9+
• ngx-template

Usage

1. Import

    import {PropertyGridModule} from 'ngx-property-grid';
   
    import {NgxTemplateModule} from 'ngx-template';

   If you need animation,you should import BrowserAnimationsModule in your app.module.ts.

2. Getting Started

   • Html

     • Basic

         <ngx-property-grid [width]="'300px'" [options]="editor"></ngx-property-grid>

     • Template

         <ngx-property-grid [width]="'300px'" [options]="editor">
             <ng-template ngxTemplate="text" let-p>
                 <input type="text" [value]="p.value" (change)="p.value = $event.target.value">
             </ng-template>
             <ng-template ngxTemplate="color" let-p>
                 <input type="color" [value]="p.value" (change)="p.value = $event.target.value">
             </ng-template>
         </ngx-property-grid>

   • Object options

       export class ExampleEditorOptions {
           @meta({name: 'Font', description: 'The font editor to use', type: SimpleTextEditorComponent, group: 'Editor', hidden: false})
           font = 'Source Code Pro';
     
           @meta({name: 'Font size', group: 'Editor', type: 'number', valueConvert: parseInt})
           fontSize = 14;
     
           @meta({name: 'Font color', group: 'Editor', type: 'color'})
           fontColor = '#51f41c';
     
           @meta({name: 'jQuery', group: 'Plugins', type: 'checkbox'})
           jQuery = true;
     
           @meta({name: 'modernizr', description: 'Whether or not to include modernizr on the page', group: 'Plugins', type: 'checkbox'})
           modernizr = false;
     
           @meta({
               name: 'Framework',
               description: 'Whether to include any additional framework',
               type: 'options',
               options: ['None', {text: 'AngularJS', value: 'angular'}, {text: 'Backbone.js', value: 'backbone'}]
           })
           framework = 'None';
       }

3. The metadata options declare

 export interface PropertyItemMeta {
    name: string; // The display name of the property in the grid
    description?: string; // A description of the property, will be used as tooltip on an hint element (a span with text "[?]")
    order?: number; // The display order.
    group?: string; //  The group this property belongs to
    hidden?: boolean; // Whether this property should be hidden in the grid, default is false (can be omitted).
    initState?: 'hidden' | 'visible'; // - hidden/visible. If hidden then subItems should init by hidden state. default is hidden
    type?: 'color' | 'date' | 'checkbox' | 'text' | 'options' | string | Type<ControlValueAccessor | ICustomDynamicComponent<any>>;
    // options: boolean number options label color,
    // or an custom component should be implement ControlValueAccessor or ICustomDynamicComponent<any>
    options?: any; // options for type
    colSpan2?: boolean; //  - true/false. If true then property input will span both columns and will have no name/label
    // (useful for textarea custom type)
    valueConvert?: (value: any) => any; // convert the value, eg. parseInt
    valueChanged?: (newValue: any, oldValue: any) => void; 
}

The metadata object

As seen from the example above the metadata object can be used (it's optional) in order to describe the object properties. Each proprty in the metadata object could have the following:

• name - The display name of the property in the grid
• description - A description of the property, will be used as tooltip on an hint element (a span with text "[?]")
• hidden - Whether this property should be hidden in the grid, default is false (can be omitted).
• group - The group this property belongs to
• type - The type of the property, supported are:
  • boolean or checkbox - A checkbox would be used
  • number - simple textbox
  • color - simple textbox
  • options - A dropdown list would be used in case the metadata contains the options array property
  • label - A label will be used, useful for uneditable / read-only properties
• colspan2 - true/false. If true then property input will span both columns and will have no name/label (useful for textarea custom type)
