NativeScript-Vue Usage Sample

In your main.js (The file where the root Vue instance is created) register the element

import { CheckBox } from '@nstudio/nativescript-checkbox';
Vue.registerElement(
'CheckBox',
() => CheckBox,
{
model: {
prop: 'checked',
event: 'checkedChange'
}
}
);

And in your template, use it as:

<check-box :checked="isChecked" @checkedChange="isChecked = $event.value" />

Use checked instead of v-model. See #99.

Properties

  • checked - boolean
  • text - text to use with the checkbox
  • fillColor - Color of the checkbox element
  • boxType - Either 'square' (default) or 'circle'. It's recommended to use 'circle' for radiobuttons. Note that plugin version 3.0.0 switched the default for iOS to 'square' for alignment with Android. Still want circle on iOS and square on Android? Just make the boxType value conditional.

Events

  • checkedChange - Use a reference to the CheckBox component to grab it's checked property when this event fires to see the new value.

API

  • toggle() - Change the checked state of the view to the inverse of its current state.

Css Styling

  • color - set the text label color
  • font-size - checkbox is sized to text from here : default 15
  • border-width - set the line width of the checkbox element: iOS only

Styling [Android]

  • checkStyle - set to the name of your drawable
  • checkPadding - set the padding of the checkbox

Add the following to app/App_Resources/Android/drawable/checkbox_grey.xml

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_checked="true" android:drawable="@drawable/ic_checkbox_checked_incomplete" />
<item android:state_enabled="false" android:state_checked="false" android:drawable="@drawable/ic_checkbox_grey_incomplete" />
<item android:state_checked="true" android:drawable="@drawable/ic_checkbox_checked_grey"/>
<item android:state_checked="false" android:drawable="@drawable/ic_checkbox_grey" />
</selector>

Radiobuttons, anyone?

Want to use radiobutton behavior for your checkboxes (only one option possible within a group)? Set boxType="circle"
