我创建了一个可移动的UserControl
<UserControl x:Class="Restaurant.Views.Managerer.TablePanel"
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:Restaurant.Helpers.Converter"
mc:Ignorable="d"
x:Name="root"
MouseLeftButtonDown="root_MouseLeftButtonDown"
MouseLeftButtonUp="root_MouseLeftButtonUp"
MouseMove="root_MouseMove"
DataContext="{Binding RelativeSource={RelativeSource Self}}">
....
码
Point anchorPoint;
Point currentPoint;
bool isInDrag = false;
private void root_MouseLeftButtonDown(object sender,MouseButtonEventArgs e)
{
var element = sender as FrameworkElement;
anchorPoint = e.GetPosition(null);
element.CaptureMouse();
isInDrag = true;
e.Handled = true;
}
private void root_MouseMove(object sender,MouseEventArgs e)
{
if (isInDrag)
{
var element = sender as FrameworkElement;
currentPoint = e.GetPosition(null);
var transform = new TranslateTransform
{
X = (currentPoint.X - anchorPoint.X),Y = (currentPoint.Y - anchorPoint.Y)
};
this.RenderTransform = transform;
anchorPoint = currentPoint;
}
}
private void root_MouseLeftButtonUp(object sender,MouseButtonEventArgs e)
{
if (isInDrag)
{
var element = sender as FrameworkElement;
element.ReleaseMouseCapture();
isInDrag = false;
e.Handled = true;
}
}
如果我改变了代码
X = (currentPoint.X - anchorPoint.X),Y = (currentPoint.Y - anchorPoint.Y)
至
X = (currentPoint.X),Y = (currentPoint.Y)
我可以移动UserControl,但鼠标和UserControl不匹配
解决方法
早上好.我睡了,可以想)))
private TranslateTransform transform = new TranslateTransform();
private void root_MouseMove(object sender,MouseEventArgs e)
{
if (isInDrag)
{
var element = sender as FrameworkElement;
currentPoint = e.GetPosition(null);
transform.X += currentPoint.X - anchorPoint.X;
transform.Y += (currentPoint.Y - anchorPoint.Y);
this.RenderTransform = transform;
anchorPoint = currentPoint;
}
}
