我是学生,在我的最后一年,我正在做一个关于WPF的项目,但我是WPF的新手,我已经分配了一些任务,但是我目前仍然坚持如何在画布上改变图像的位置。从左到右。下面是代码
%template(QuadKeyVector) vector<::QuadKey::QuadKey>;
Xaml.cs
<<Window x:Class="changing_bird_position.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="450" Width="800">
<StackPanel>
<Canvas Name="canvas" Background="LightBlue" Width="500" Height="280" Margin="264,0,28,0">
<Image Source="inlandbird.png" Name="Image" Height="43" Canvas.Left="55" Canvas.Top="22"/>
</Canvas>
<Button Content="Button" Click="Button_Click" Width="50" Height="50" Margin="246,0"/>
</StackPanel>

在你的代码背后,你不需要创建这个图像实例(img)。您可以通过它的名称属性访问该图像。
我在xaml中重命名了图像以使其清晰。
XAML:
<Window x:Class="WpfApplication15.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="450" Width="800">
<StackPanel>
<Canvas Name="canvas" Background="LightBlue" Width="500" Height="280" Margin="264,0,28,0">
<Image Source="inlandbird.png" Name="BirdImage" Height="43" Canvas.Left="55" Canvas.Top="22"/>
</Canvas>
<Button Content="Button" Click="Button_Click" Width="50" Height="50" Margin="246,0"/>
</StackPanel>
</Window>
代码背后:
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
Canvas.SetLeft(BirdImage, 200.0);
Canvas.SetTop(BirdImage, 200.0);
}
}
}
