QWidget examples

Every example below can be pasted straight into the editor; replace URLs and paths as needed.

Example 1: daily news

<Widget Name="每日新闻" Version="1.0.0"
        UpdateUrl="https://example.com/news.qwidget">
  <Data Name="News" Type="Json"
        Url="https://api.example.com/news" Refresh="3600" />

  <Container Padding="4" Gap="3" Border="True" Radius="Lg" Background="Card">
    <Text Value="{Data.News.Title}" Size="Lg" Weight="Bold" />
    <List Items="{Data.News.Items}" As="Item" Gap="2" EmptyText="暂无新闻">
      <ListItem>
        <Row Gap="2" Align="Center">
          <Text Value="{Item.Title}" Size="Sm" Clamp="2" />
          <Button Text="阅读" Size="Sm" Variant="Ghost"
                  OnClick="OpenUrl" Url="{Item.Url}" />
        </Row>
      </ListItem>
    </List>
    <If Test="{State.Error}">
      <Text Value="数据加载失败" Size="Xs" Color="Destructive" />
    </If>
  </Container>
</Widget>

Key points: named Data sources, List + ListItem, If Test, and OpenUrl with a dynamic URL.

Example 2: quick search

<Widget Name="快捷搜索" Version="1.0.0">
  <Container Padding="3" Gap="2">
    <TextBox Name="Keyword" Placeholder="输入关键词" />
    <Button Text="搜索" OnClick="CallFunction" Function="Search" />
    <List Items="{Results.Search.Items}" As="Item" EmptyText="没有结果">
      <ListItem>
        <Text Value="{Item.Title}" Size="Sm" />
      </ListItem>
    </List>
  </Container>

  <Function Name="Search" Timeout="3000">
    <Function.Interface>
      <Struct Name="SearchInput">
        <Field Name="Keyword" Type="String" />
      </Struct>
      <Struct Name="SearchItem">
        <Field Name="Title" Type="String" />
      </Struct>
    </Function.Interface>
    <Function.Input Type="SearchInput">Input</Function.Input>
    <Function.Output Type="Json">Items</Function.Output>
    <Function.Script><![CDATA[
      const keyword = (Input.Keyword || "").trim();
      return {
        Items: keyword
          ? [{ Title: "结果 1：" + keyword }, { Title: "结果 2：" + keyword }]
          : []
      };
    ]]></Function.Script>
  </Function>
</Widget>

Key points: Inputs are assembled automatically from the struct fields, and function results are written to Results.

Example 3: local music card

<Widget Name="音乐卡片" Version="1.0.0">
  <Data Name="Track" Type="Binary" Source="File" Path="C:\Music\song.mp3" />
  <Container Padding="3" Gap="2">
    <Text Value="正在播放" Weight="Semibold" />
    <Media Type="Audio" Source="{Data.Track.Url}"
           Controls="True" Loop="True" Volume="0.8" />
  </Container>
</Widget>

Key points: Binary data yields a Blob URL that can go straight into Media.Source.

Example 4: nested widgets

<!-- create a local widget named StatusCard first -->
<Widget Name="Dashboard" Version="1.0.0">
  <Row Gap="2">
    <Widget.Using Name="StatusCard" As="Players" />
    <Widget.Using Name="StatusCard" As="Tps" />
  </Row>
  <Text Value="{Children.Players.Data.Value}" Size="Lg" />
</Widget>

Key points: As aliases are unique and the parent reads Children.* only.

Example 5: the three syntaxes side by side

<!-- attribute syntax -->
<Text Value="Hello" />

<!-- content syntax -->
<Text>Hello</Text>

<!-- property element syntax -->
<Text><Text.Value>Hello</Text.Value></Text>

Example 6: shortcuts

<Widget Name="快捷入口" Version="1.0.0">
  <Container Padding="3" Gap="2">
    <Grid Columns="2" Gap="2">
      <Button Text="启动游戏" OnClick="Launch" />
      <Button Text="实例管理" OnClick="Navigate" To="Instances" />
      <Button Text="资源中心" OnClick="Navigate" To="ResourceCenter" />
      <Button Text="打开日志" OnClick="OpenFolder" Folder="Logs" />
    </Grid>
  </Container>
</Widget>
