在app.xaml中添加<vm:PropertyConfigSetViewModel x:Key="PropertyConfigSetViewModel"/>,后在窗口界面中如何设置datacontext属性
时间: 2024-05-07 19:23:00 浏览: 18
可以在窗口的XAML文件中添加以下代码:
```xaml
<Window.DataContext>
<vm:PropertyConfigSetViewModel />
</Window.DataContext>
```
这样就可以将窗口的DataContext设置为PropertyConfigSetViewModel实例了。其中,vm表示ViewModel所在的命名空间。如果命名空间不同,请根据实际情况进行修改。

要给这个自定义控件添加Thumb,可以在ItemsControl的外层包裹一个Grid,然后在Grid的右下角添加一个Thumb。以下是修改后的代码示例:
```
<Grid>
<ItemsControl x:Name="itemCtrl" ItemsSource="{Binding Path=Title2, RelativeSource={RelativeSource Mode=Self}}" FontSize="20" Foreground="Teal" >
<ItemsControl.ItemContainerStyle>
<Style TargetType="ContentPresenter">
<Setter Property="VerticalAlignment" Value="Center" />
</Style>
</ItemsControl.ItemContainerStyle>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<Border Margin="{Binding Path=CharacterSpacing, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}">
<TextBlock Text="{Binding}" />
</Border>
<Rectangle Height="1" Fill="{Binding Foreground, ElementName=itemCtrl}" Margin="0,0,0,5">
<Rectangle.Style>
<Style TargetType="Rectangle">
<Setter Property="Visibility" Value="Collapsed" />
<Style.Triggers>
<DataTrigger Binding="{Binding ShowUnderline, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}" Value="True">
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
</Rectangle.Style>
</Rectangle>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
<Thumb DragDelta="Thumb_DragDelta" Width="10" Height="10" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
```
注意,这里我添加了一个Thumb,并且为它绑定了DragDelta事件。您需要在代码中实现Thumb_DragDelta方法,以便在Thumb被拖动时进行相应的处理。
<ItemsControl x:Class="HDSProject.Control.CustomFont" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:HDSProject.Control" mc:Ignorable="d" d:DesignHeight="450" d:DesignWidth="800" x:Name="itemCtrl" ItemsSource="{Binding Path=Title2, RelativeSource={RelativeSource Mode=Self}}" FontSize="20" Foreground="Teal" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Border Margin="{Binding Path=CharacterSpacing, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}"> <TextBlock Text="{Binding}" /> <Border.Style> <Style TargetType="Border"> <Setter Property="BorderThickness" Value="0"/> <Style.Triggers> <DataTrigger Binding="{Binding ShowUnderline, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}" Value="True"> <Setter Property="BorderThickness" Value="0 0 0 1"/> </DataTrigger> </Style.Triggers> </Style> </Border.Style> <Border.BorderBrush> <SolidColorBrush Color="{Binding Foreground.Color, ElementName=itemCtrl}" /> </Border.BorderBrush> </Border> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl>我希望输入的Title2可以换行,且可以设置行间距该怎么做
您可以将StackPanel替换为一个WrapPanel,这样就可以实现Title2的换行了。而要设置行间距,您可以在WrapPanel中添加一个Margin属性,来实现行间距的设置。具体的修改代码如下:
```
<ItemsControl x:Class="HDSProject.Control.CustomFont"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:HDSProject.Control"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800"
x:Name="itemCtrl"
ItemsSource="{Binding Path=Title2, RelativeSource={RelativeSource Mode=Self}}"
FontSize="20" Foreground="Teal">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" Margin="0 10 0 0"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border Margin="{Binding Path=CharacterSpacing, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}">
<TextBlock Text="{Binding}" />
<Border.Style>
<Style TargetType="Border">
<Setter Property="BorderThickness" Value="0"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ShowUnderline, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=local:CustomFont}}" Value="True">
<Setter Property="BorderThickness" Value="0 0 0 1"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Border.Style>
<Border.BorderBrush>
<SolidColorBrush Color="{Binding Foreground.Color, ElementName=itemCtrl}" />
</Border.BorderBrush>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
```
在WrapPanel中加入了Margin属性,实现了行间距的设置。
