问题描述
我使用 WPF 已经有一段时间了.
I have been working with WPF for some time.
我需要在 Internet 上创建以下控件,但找不到合适的.
I need to create the following control over Internet, but could not find appropriate.
任何人都可以帮助如何实现此功能.单击控件时,值应增加或减少.我发现我可以使用音量控制或滑块,但不清楚我应该使用什么.
Can anybody help how to implement this functionality. Value should be increasing or decreasing when clicked on control. I found that I can use either Volume control or Slider, but not getting clear what I should use.
期待中的感谢.
推荐答案
我更喜欢将 Progressbar 用于这些类型的显示.这是我对简单音量控制的实现,看起来很像您作为示例展示的:
I prefer to use a Progressbar for these kind of displays. This is my implementation of a simple volume control looking pretty much like the one you show as an example:
public partial class MainWindow : Window, INotifyPropertyChanged
{
private double _volume;
private bool mouseCaptured = false;
public double Volume
{
get { return _volume; }
set
{
_volume = value;
OnPropertyChanged("Volume");
}
}
public MainWindow()
{
InitializeComponent();
DataContext = this;
}
private void MouseMove(object sender, MouseEventArgs e)
{
if (Mouse.LeftButton == MouseButtonState.Pressed && mouseCaptured)
{
var x = e.GetPosition(volumeBar).X;
var ratio = x/volumeBar.ActualWidth;
Volume = ratio*volumeBar.Maximum;
}
}
private void MouseDown(object sender, MouseButtonEventArgs e)
{
mouseCaptured = true;
var x = e.GetPosition(volumeBar).X;
var ratio = x / volumeBar.ActualWidth;
Volume = ratio * volumeBar.Maximum;
}
private void MouseUp(object sender, MouseButtonEventArgs e)
{
mouseCaptured = false;
}
#region Property Changed
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
#endregion
}
还有 XAML:
<Window x:Class="VolumeControlApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="196" Width="319">
<Window.Resources>
<Style x:Key="VolumeStyle" TargetType="{x:Type ProgressBar}">
<Setter Property="Foreground" Value="#FFB00606"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Grid x:Name="TemplateRoot">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"/>
<Rectangle x:Name="PART_Track"/>
<Grid x:Name="PART_Indicator" ClipToBounds="True" HorizontalAlignment="Left">
<Rectangle x:Name="Indicator" Fill="{TemplateBinding Foreground}" RadiusX="5" RadiusY="3"/>
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid Background="#FF363636">
<Border Background="Gray" BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Center" VerticalAlignment="Center" CornerRadius="3" Padding="2">
<Border Background="Black" CornerRadius="3">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Text="Vol:" Foreground="White" VerticalAlignment="Center" Margin="4 0"/>
<ProgressBar x:Name="volumeBar" Height="10"
Value="{Binding Volume}"
Width="100"
MouseMove="MouseMove"
MouseDown="MouseDown"
MouseUp="MouseUp" Style="{DynamicResource VolumeStyle}" Grid.Column="1"/>
</Grid>
</Border>
</Border>
</Grid>
</Window>
