将文本添加到Compose.jl形状

Question

我想在Compose.jl上覆盖形状上的文字。例如，假设我想在这个形状的中心叠加一个标签：

    <Page
    x:Class="App1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App1"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <WebView Source="http://appstest.local/Survey" x:Name="WebView" Visibility="Visible" HorizontalAlignment="Left" Height="720" VerticalAlignment="Top" Width="1280"/>
    </Grid>
</Page>

如何将文字叠加到这些对象上？

Answer 1

以下是一些代码片段，它覆盖了某些形状的文字：

try:
    from threading import _Timer
except ImportError:
    from threading import Timer as _Timer  # Python 3.3+

def named_timer(name, interval, function, *args, **kwargs):
    """Factory function to create named Timer objects.

      Timers call a function after a specified number of seconds:

          t = Timer('Name', 30.0, function)
          t.start()
          t.cancel()  # stop the timer's action if it's still waiting
    """
    timer = _Timer(interval, function, *args, **kwargs)
    timer.name = name
    return timer

if __name__ == '__main__':

    def func():
        print('func() called')

    timer = named_timer('Fidgit', 15, func)
    print('timer.name: {!r}'.format(timer.name))  # -> timer.name: 'Fidgit'
    timer.run()  # causes "func() called" to be printed 15 seconds later

代码产生以下输出：

compose( context(), fill("black"), (context(0.2, 0.5), text(0.2, 0.1,"eeee", Compose.hcenter, Compose.vcenter)), (context(0.2, 0.5, 0.4, 0.2), rectangle(), fill("green")), (context(0.0, 0.6), text(0.25, 0.1, "aaaaaaaaaaabbbbbbbbbbbbcccccccc", Compose.hcenter, Compose.vcenter)), (context(0.0, 0.6, 0.5, 0.2), rectangle(), fill("red")) ) 的两个第一个参数是文本相对于当前上下文的位置。

text()和Compose.hcenter是可选的，它们设置文本的水平和垂直对齐方式。用于对齐的选项是：

• Compose.vcenter
• vleft
• vcenter
• vright
• htop
• hcenter

不幸的是我没有找到要链接到的hbottom函数的文档，只有它的定义，可以在github上找到here。
