View¶

Overview¶

The <view> tag can be used in:

<component>s
<widget>s
<screen>s
<test>s

to describe how these items look. Inside <view>, children can be added in a nested way using already defined widgets and components. For example:

<view>
    <lv_button width="200">
        <my_icon src="image1"/>
        <lv_label text="Click me"/>
    </lv_button>
</view>

Extends¶

The <view> itself is also a widget or component, which will become the parent of the children. To define the type of the <view>, use the extends attribute. For example, extends="lv_slider". In this case, an lv_slider will be created first, and the children will be added to it.

By adding properties to the <view>, the extended type can be customized. For example:

<view extends="lv_slider" width="100%" style_bg_color="0xff8800" flex_flow="row">
    <style name="my_style" selector="pressed|knob"/>
    <lv_label text="Current value: "/>
    <lv_label bind_text="subject_1"/>
</view>

Rules for the allowed values of extends:

<component>: can extend both <widget>s and <component>s
<widget>: can extend only <widget>s
<screen>: cannot extend anything
<test>: can extend <widget>, <component>, or <screen>
