Posted 2023-03-19

本主题介绍 TimePicker 控件的样式和模板。 你可以修改这些资源和默认 ControlTemplate 以便为该控件提供一个唯一的外观。
视觉状态
TimePicker 默认样式不定义任何视觉状态。
主题资源
这些资源在该控件的默认样式中使用。
深色主题画笔
若要在深色主题下更改该控件的颜色，请在 App.xaml 中替代这些画笔。
XAML
<SolidColorBrush x:Key="TimePickerHeaderForegroundThemeBrush" Color="#FFFFFFFF" />
<SolidColorBrush x:Key="TimePickerForegroundThemeBrush" Color="#FF000000" />

浅色主题画笔
若要在浅色主题下更改该控件的颜色，请在 App.xaml 中替代这些画笔。
XAML

<SolidColorBrush x:Key="TimePickerForegroundThemeBrush" Color="#FF000000" />

其他资源
XAML
<x:Double x:Key="TimePickerSelectorThemeMinWidth">80</x:Double>
<Thickness x:Key="TimePickerHeaderThemeMargin">0,0,0,6</Thickness>
<Thickness x:Key="TimePickerFirstHostThemeMargin">0,0,20,0</Thickness>
<Thickness x:Key="TimePickerThirdHostThemeMargin">20,0,0,0</Thickness>
<FontWeight x:Key="TimePickerHeaderThemeFontWeight">SemiLight</FontWeight>

共享资源
该控件模板使用这些与其他控件模板共享的资源。更改这些值将影响使用这些资源的其他控件。
