继续我之前的问题create dynamically complex controls in wpf 我的代码基于可移动和可调整大小的形状的代码项目article
最初我创建了一个可在我的xaml中调整大小的控件,并且在代码中创建控件的副本时出现问题。 现在,这个问题已经解决了,但我已经添加了移动我的可调整大小控件的功能,它完美地工作,但是在代码中创建的副本只会调整大小而不会移动,我不知道为什么会这样。 / p>
这是我的xaml:
<Window x:Class="MazeBuilder.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:s="clr-namespace:MazeBuilder"
Title="MainWindow" Height="480" Width="640">
<Window.Resources>
<!-- MoveThumb Template -->
<ControlTemplate x:Key="MoveThumbTemplate" TargetType="{x:Type s:MoveThumb}">
<Rectangle Fill="Transparent"/>
</ControlTemplate>
<!-- ResizeDecorator Template -->
<ControlTemplate x:Key="ResizeDecoratorTemplate" TargetType="{x:Type Control}">
<Grid>
<s:ResizeThumb Height="3" Cursor="SizeNS" Margin="0 -4 0 0"
VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
<s:ResizeThumb Width="3" Cursor="SizeWE" Margin="-4 0 0 0"
VerticalAlignment="Stretch" HorizontalAlignment="Left"/>
<s:ResizeThumb Width="3" Cursor="SizeWE" Margin="0 0 -4 0"
VerticalAlignment="Stretch" HorizontalAlignment="Right"/>
<s:ResizeThumb Height="3" Cursor="SizeNS" Margin="0 0 0 -4"
VerticalAlignment="Bottom" HorizontalAlignment="Stretch"/>
<s:ResizeThumb Width="7" Height="7" Cursor="SizeNWSE" Margin="-6 -6 0 0"
VerticalAlignment="Top" HorizontalAlignment="Left"/>
<s:ResizeThumb Width="7" Height="7" Cursor="SizeNESW" Margin="0 -6 -6 0"
VerticalAlignment="Top" HorizontalAlignment="Right"/>
<s:ResizeThumb Width="7" Height="7" Cursor="SizeNESW" Margin="-6 0 0 -6"
VerticalAlignment="Bottom" HorizontalAlignment="Left"/>
<s:ResizeThumb Width="7" Height="7" Cursor="SizeNWSE" Margin="0 0 -6 -6"
VerticalAlignment="Bottom" HorizontalAlignment="Right"/>
</Grid>
</ControlTemplate>
<!-- Designer Item Template-->
<ControlTemplate x:Key="DesignerItemTemplate" TargetType="ContentControl">
<Grid DataContext="{Binding RelativeSource={RelativeSource TemplatedParent}}">
<Control Template="{StaticResource ResizeDecoratorTemplate}"/>
<s:MoveThumb Template="{StaticResource MoveThumbTemplate}" Cursor="SizeAll"/>
<ContentPresenter Content="{TemplateBinding ContentControl.Content}"/>
</Grid>
</ControlTemplate>
</Window.Resources>
<Canvas x:Name="LayoutRoot" MouseDown="LayoutRoot_MouseDown" MouseMove="LayoutRoot_MouseMove">
<Popup Name="PopupEsales" Placement="Right" IsEnabled="True" IsOpen="False" Grid.RowSpan="2">
<ListView Height="145" HorizontalAlignment="Stretch" Margin="0,0,0,0" Name="lvSalesPersonIdSearch" VerticalAlignment="Top" Width="257" >
<ListView.View>
<GridView>
<GridViewColumn Header="Sales Persons Id" Width="100" DisplayMemberBinding="{Binding Path=SPID}" />
<GridViewColumn Header="Name" Width="100" DisplayMemberBinding="{Binding Path=Name}" />
</GridView>
</ListView.View>
</ListView>
</Popup>
<Menu Height="23" IsMainMenu="True" HorizontalAlignment="Left" Name="menu1" VerticalAlignment="Top" Width="640">
<MenuItem Header="File">
<MenuItem Header="New Maze" Click="New_Click" />
<MenuItem Header="Load Maze" Click="Load_Click" />
<MenuItem Header="Save Maze" Click="Save_Click" />
</MenuItem>
<MenuItem Header="Tools">
<MenuItem Header="Show" Click="ShowTools_Click" />
</MenuItem>
</Menu>
<ContentControl Width="130"
MinWidth="50"
Height="130"
MinHeight="50"
Canvas.Top="150"
Canvas.Left="470"
Template="{StaticResource DesignerItemTemplate}">
<Rectangle Fill="Blue"
IsHitTestVisible="False"/>
</ContentControl>
<Canvas.Background>
<SolidColorBrush Color="White" Opacity="0"/>
</Canvas.Background>
</Canvas>
这是我试图复制的控件:
<ContentControl Width="130"
MinWidth="50"
Height="130"
MinHeight="50"
Canvas.Top="150"
Canvas.Left="470"
Template="{StaticResource DesignerItemTemplate}">
<Rectangle Fill="Blue"
IsHitTestVisible="False"/>
</ContentControl>
这是我的代码,用于创建控件的新实例:
ContentControl cc = new ContentControl();
ControlTemplate ct = new ControlTemplate();
object rs = this.Resources["DesignerItemTemplate"];
ct = (ControlTemplate)rs;
cc.Template = ct;
cc.Height = 10;
cc.Width = 10;
cc.Content = new Rectangle { Fill = new SolidColorBrush(Color.FromRgb(0,0,255)) };
LayoutRoot.Children.Add(cc);
Canvas.SetLeft(cc, 300);
Canvas.SetTop(cc, 300);
这会创建一个可调整大小的控件,但它根本不会移动,并且当鼠标悬停在光标上时光标不会像在xaml中创建的那样更改。我相信我已经分配了正确的资源,我不明白为什么这不起作用。
答案 0 :(得分:1)
您未在IsHiteTestVisible = false
上设置Rectangle
。这就是问题所在,因为您的ContentPresenter
位于模板中的MoveThumb
之上。我不确定MoveThumb
的样子,但如果它只是一个透明的矩形,我会把它放在ContentPresenter
的顶部,这样你就不用担心设置IsHitTestVisible
了。 1}}关于你添加的所有孩子。
