需求:界面由多部分控件组成,想要拖拽控件之间的分隔栏以改变尺寸。
MainWindow.xaml:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300"/>
<ColumnDefinition Width="300"/>
</Grid.ColumnDefinitions>
<ListBox Grid.Row="0" Grid.Column="0">
<ListBoxItem>aaaa</ListBoxItem>
<ListBoxItem>bbbb</ListBoxItem>
<ListBoxItem>cccb</ListBoxItem>
</ListBox>
<TextBlock Grid.Row="0" Grid.Column="1">sadfas</TextBlock>
<GridSplitter Grid.Row="0" Grid.Column="0" Width="0" VerticalAlignment="Stretch" HorizontalAlignment="Right"/>
</Grid>
运行效果如下:
红色虚线表示了拖动分隔栏以改变控件的尺寸边缘。
坑点:
<StackPanel Orientation="Horizontal">
<TextBlock Text="LLLLLLLLLLLLLL"/>
<GridSplitter Width="10" HorizontalAlignment="Center" VerticalAlignment="Stretch" Background="Wheat"/>
<TextBlock Text="RRRRRRRRRRRRRR"/>
</StackPanel>
再来一个详细一点的例子:
<Window x:Class="WpfApplication1.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:WpfApplication1"
xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"
mc:Ignorable="d"
Title="MainWindow" Height="600" Width="1000">
<Grid>
<Grid.RowDefinitions/>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="10"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="LLLLLLLLLLLLLL"/>
<GridSplitter Grid.Row="0" Grid.Column="1" Width="10" HorizontalAlignment="Center" VerticalAlignment="Stretch" Background="Wheat"/>
<Grid Grid.Row="0" Grid.Column="2">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="10"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="RRRRRRTTTTTTTT"/>
<GridSplitter Grid.Row="1" Grid.Column="0" Height="10" HorizontalAlignment="Stretch" Background="Wheat"/>
<TextBlock Grid.Row="2" Grid.Column="0" Text="RRRRRRBBBBBBBB"/>
</Grid>
</Grid>
</Window>
运行效果如图:下面的水平和垂直的黄色分隔栏都是可以拖动的。
