StackPanel内的WPF ViewBox

提问于

我试图展示像记分板一样的东西,团队名称在前方的25%,得分低于75%(适当的字体比率) . 我也希望这些控件在窗口调整大小时增长/缩小 .

为此,我创建了一个网格并将其拆分为 *3* 行 . 我在顶行添加了一个TextBlock,在底部4行添加了另一个TextBlock . 然后我将每个TextBox包装在ViewBox中

这会导致应用程序进入“中断模式” .

这显示了问题:

<Window x:Class="WpfRandoms.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfRandoms"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="3*"/>
        </Grid.RowDefinitions>

        <ListView ItemsSource="{Binding Teams}" HorizontalAlignment="Center" Grid.Row="0" BorderBrush="{x:Null}" Background="{x:Null}">
            <ListView.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ListView.ItemsPanel>
            <ListView.ItemContainerStyle>
                <Style TargetType="{x:Type ListViewItem}">
                    <Setter Property="Background" Value="Transparent" />
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type ListViewItem}">
                                <ContentPresenter />
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </ListView.ItemContainerStyle>
            <ListView.ItemTemplate>
                <DataTemplate>
                    <Border Margin="10" Padding="10" CornerRadius="5" Width="{Binding Path=ActualHeight, RelativeSource={RelativeSource Self}}">
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="*" />
                                <RowDefinition Height="3*" />
                            </Grid.RowDefinitions>
                            <Viewbox Grid.Row="0">
                                <TextBlock Text="{Binding Name}" TextAlignment="Center" />
                            </Viewbox>
                            <Viewbox Grid.Row="1">
                                <TextBlock Text="{Binding Score}" FontSize="40" TextAlignment="Center" />
                            </Viewbox>
                        </Grid>
                    </Border>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </Grid>
</Window>

代码隐藏:

using System.Collections.Generic;
using System.Windows;

namespace WpfRandoms
{
    public partial class MainWindow : Window
    {
        public class Team
        {
            public string Name { get; set; }
            public int Score { get; set; }
        }

        public IList<Team> Teams { get; private set; }

        public MainWindow()
        {
            InitializeComponent();

            Teams = new List<Team>();
            Teams.Add(new Team() { Name = "Team A", Score = 78 });
            Teams.Add(new Team() { Name = "Team B", Score = 1 });
            Teams.Add(new Team() { Name = "Team C", Score = 101 });

            DataContext = this;
        }
    }
}

这似乎是由ListPanel用作ListView的ItemsPanelTemplate引起的(没有这个StackPanel一切正常,但布局不是很理想) . 但是,我不知道另一种使ListView水平的方法,所以我坚持使用StackPanel .

经过一些实验和阅读ViewBox如何工作,以及StackPanels如何表现我得到了一些解决方案(可能不是最好的解决方案) .
我将ListView包装在Border中,然后将ListView的DataTemplate中Border的高度绑定到Border外部的高度 .
因此存在一个小的限制 - 主要是顶部/底部边距导致ListView的元素被修剪 . 为了避免这种修剪,我在DataTemplate中添加了填充到边框,然后在其中添加了一个具有背景等的较小边框 .
我还必须隐藏ListView的垂直滚动条 .
这是我有的:

                </ListView.ItemTemplate>
            </ListView>
        </Border>
    </Grid>
</Window>

如果有更好的解决方案,我会非常感激:)

    我不确定我是否完全理解你的问题 . 如果您希望保持名称和分数之间的比率相同,则可以使用“*”作为名称(25%),使用“3 *”作为分数(75%) . 您还可以将每个TextBlock放在Viewbox中而不是整个内容中 . 为了简单起见,我用硬编码字符串替换了转换器和绑定 .

    <Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Border Margin="10" Padding="10" CornerRadius="5" Background="Coral">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="3*" />
                </Grid.RowDefinitions>
                <Viewbox Grid.Row="0">
                    <TextBlock Text="Home" TextAlignment="Center" />
                </Viewbox>
                <Viewbox Grid.Row="1" >
                    <TextBlock Grid.Row="1" Text="25" TextAlignment="Center" />
                </Viewbox>
            </Grid>
        </Border>
    </Grid>

    我认为您在边界控件上引用的转换器可能有问题 .

    我在没有绑定的情况下测试了您的XAML,并且视图框按预期工作 .

    <Border Margin="10" Padding="10" CornerRadius="5" Width="{Binding Path=ActualHeight, RelativeSource={RelativeSource Self}}">
            <Viewbox>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto" />
                        <RowDefinition Height="*" />
                    </Grid.RowDefinitions>
                    <TextBlock Text="Team Name" TextAlignment="Center" Grid.Row="0" />
                    <TextBlock Text="100" FontSize="100" TextAlignment="Center" Grid.Row="1" Grid.RowSpan="3"/>
                </Grid>
            </Viewbox>
        </Border>
    

    希望这有帮助!
