要實現擬物音量控件,可以按照以下步驟進行:
<Slider x:Name="VolumeSlider" Minimum="0" Maximum="100" ValueChanged="VolumeSlider_ValueChanged"/>
<TextBlock x:Name="VolumeTextBlock" Text="0" HorizontalAlignment="Center" VerticalAlignment="Center"/>
private void VolumeSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
int volume = (int)VolumeSlider.Value;
VolumeTextBlock.Text = volume.ToString();
}
<Slider x:Name="VolumeSlider" Minimum="0" Maximum="100" ValueChanged="VolumeSlider_ValueChanged">
<Slider.Style>
<Style TargetType="Slider">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Slider">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Rectangle Grid.Column="0" Width="20" Height="20" Fill="#FF007ACC"/>
<Rectangle Grid.Column="1" Height="4" VerticalAlignment="Center" Fill="#FF007ACC" Margin="10,0,10,0"/>
<Thumb x:Name="PART_Track" Grid.ColumnSpan="2" Grid.RowSpan="3" Width="20" Height="20" Background="Transparent"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Slider.Style>
</Slider>
這樣就實現了一個簡單的擬物音量控件。你可以根據需求對外觀進行進一步的美化和定制化。
