All components are inheritable, you can further extend functionalities of specific component by simple create a subclass of component main class. To get access to the TreeView component import the IntegralUITreeViewModule in your application. For other common components, import the IntegralUICommonModule.

Dependencies

IntegralUI TreeView requires only the following library:

Angular - v8.0 and above

Online QuickStart App - An online demo of each component included

Installation

Install the repository by running

npm install https://github.com/lidorsystems/integralui-treeview.git

Open your application module and add a reference to the IntegralUIBaseListModule and IntegralUITreeViewModule

import { IntegralUIBaseListModule } from 'node_modules/integralui-treeview/bin/integralui/integralui.baselist.module';
import { IntegralUITreeViewModule } from 'node_modules/integralui-treeview/bin/integralui/integralui.treeview.module';

@NgModule({
  imports:      [ IntegralUIBaseListModule, IntegralUITreeViewModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Note Common components like Button, Calendar, CheckBox etc. are included in IntegralUICommonModule. In order to use them, you also need to import the module from '~ ... integralui/integralui.common.module.ts' file. Depending on the component, the standard FormsModule from Angular framework may also be required to import.

Note In order to use a specific component or directive in your application, follow the guidelines from corresponding article. You can find a separate article available for each component or directive.

Angular CLI

After installation, in angular.json under styles section add this code line:

"node_modules/integralui-treeview/bin/integralui/css/integralui.treeview.module.css"

To apply a theme, also add code line for corresonding theme file. For example to use the Office theme, add this:

"node_modules/integralui-treeview/bin/integralui/themes/integralui.themes.office.css"

Note You can choose a theme from available themes located at '~ ... /integralui/themes' folder.

To include resources that are used by IntegralUI components in your project during build, you need to:

Under assets folder create a subfolder named integralui
Copy/Paste the node_modules/integralui-treeview/bin/integralui/resources folder to it
Add the following code under assets section in angular.json file:

"src/assets/integralui/resources"

Then you can access these resources by specifing its location in your project CSS files. For example:

.some-class
{
    background-image: url(src/assets/integralui/resources/computer.png).
}

Note This is required because Angular compiler cannot detect resources that are outside the /src section of your app. It is needed if you are using resources that are part of IntegralUI Web, in your application.

Creating Custom Styles for IntegralUI Components

When you create custom styles or changes to built-in CSS classes of IntegralUI components, placed for example within app.component.css file, make sure ViewEncapsulation is set to None. This allows to override default settings from corresponding component css file. For example:

app.component.ts

import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
}

app.component.css

.iui-treeview
{
  width: 400px;
  height: 300px;
}

In this example, the TreeView component will have its width and height set from within the app.component.

Note Changes to ViewEncapsulation set to None is avoidable, if you create your own CSS style sheet and include it in angular.json file under styles section. Like it is explained above for general IntegralUI styles.

QuickStart App

There is a demo application with source code that contains samples for each component included. You can access this app from the IntegralUI Web repository. It can help you to get started quickly with learning about the components and write tests immediatelly.

In order to start this application, you only need to install the latest Angular library. Open the nodejs command prompt, go to application directory and type:

    npm install

After installation completes, start the application by typing:

    ng serve --open

The application will start displaying the main window with links to all components included. Each component window contains a demo and description about the component functionality. You can checkout the sample source code (located under integralui-web/quickstart/src/app/samples subfolder) for more information on the sample and component used.
