当我用鼠标拖动窗口时，如何调整整个窗口的大小

Question

在使用WinForms应用程序之前，我是WPF控件的新手，在那里，如果我在控件上加锚，在容器上加码头，一切都能顺利工作，但在这里，我很难找到错误的地方？

<Window x:Class="ChatApp.Client.ClientWindow"
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:ChatApp.Client"
mc:Ignorable="d"
Title="Client" Height="450" Width="800">
<Grid>
<DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<StackPanel DockPanel.Dock="Top" Orientation="Horizontal" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<GroupBox Header="Client" Height="Auto">
<StackPanel Orientation="Horizontal">
<TextBlock Margin="5, 0, 5, 0">Address:</TextBlock>
<TextBox x:Name="txtAddress" Width="80"></TextBox>
<TextBlock Margin="10, 0, 5, 0">Port:</TextBlock>
<TextBox x:Name="txtPort" Width="80"></TextBox>
<Button x:Name="btnConnect" Margin="430, 0, 5, 0" Content="Connect" Width="80" Click="btnConnect_Click"/>
</StackPanel>
</GroupBox>
</StackPanel>
<StackPanel DockPanel.Dock="Left" Orientation="Horizontal" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<GroupBox Header="Chat" Width="650" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<TextBox x:Name="txtConversation" AcceptsReturn="True"></TextBox>
</GroupBox>
</StackPanel>
<StackPanel DockPanel.Dock="Right" Orientation="Horizontal" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<GroupBox Header="Users" Width="135" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<ListBox x:Name="lbUsers" Height="Auto" Margin="5,0" VerticalAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</GroupBox>
</StackPanel>
</DockPanel>
</Grid>
</Window>

我有三组箱顶坞，第二组左坞，最后一组右坞。当我想用鼠标右键调整窗体大小时，组框不想拉伸我调整表单大小。

您的布局似乎过于复杂了——您只是想在WPF中克隆Winforms中的内容吗？

• 让StackPanels或Grid每个都只有一个子控件是没有任何意义的
• 尝试用适当大小的网格行和列替换DockPanel
• 如果您对GroupBoxes的宽度进行硬编码，则不会调整其大小
• 不需要为ListBox定义ItemTemplate来显示单个字符串

以下内容将是布局的良好起点。

<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>

<Grid.ColumnDefinitions>
<ColumnDefinition Width="4*"  />
<ColumnDefinition Width="*" MinWidth="135" />
</Grid.ColumnDefinitions>
<GroupBox Header="Client" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Margin="5">
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>

<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>

<TextBlock Grid.Row="0" Grid.Column="0" Text="Address:"/>
<TextBox x:Name="txtAddress" Width="80" Grid.Row="1" Grid.Column="0" />
<TextBlock Grid.Row="2" Grid.Column="0" Text="Port:" />
<TextBox x:Name="txtPort" Width="80" Grid.Row="3" Grid.Column="0" />
<Button x:Name="btnConnect" Grid.Row="0" Grid.Column="2" Content="Connect" Width="80" />
</Grid>
</GroupBox>

<GroupBox Header="Chat" Grid.Row="1" Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<TextBox x:Name="txtConversation" AcceptsReturn="True" />
</GroupBox>

<GroupBox Header="Users" Grid.Row="1" Grid.Column="1" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<ListBox x:Name="lbUsers" />
</GroupBox>
</Grid>
