WPF中的可拖动控件？ [英] Dragable control in WPF?

问题描述

我对WPF有一些新的感觉，尽管我在Form中有一些经验，但我决定终于设法弄清楚如何使用WPF。所以当我得到可拖动的控件，这是我提出的代码（我试图改变它使用WPF，但控制只是抽搐无处不在）：

  private void rectangle1_MouseMove（object sender，MouseEventArgs e）
 {
 if（e.LeftButton == MouseButtonState.Pressed）{
 double x = this.Left + （双）e.GetPosition（this）.X  - （double）rectangle1.Margin.Left; 
 double y = this.Top +（double）e.GetPosition（this）.Y  - （double）rectangle1.Margin.Top; 
 rectangle1.Margin = new Thickness（x，y，rectangle1.Margin.Right，rectangle1.Margin.Bottom）; 
} 
} 
  

解决方案

你想要使用装饰实现拖动，调整大小，旋转等。

Im kind of new to WPF although I have some experience in Forms, and I decided to finally try to figure out how to use WPF. So When I got to dragable controls, this is the code I came up with (I attempted to change it to work with WPF but the control just twitches everywhere):

private void rectangle1_MouseMove(object sender, MouseEventArgs e)
{
    if (e.LeftButton == MouseButtonState.Pressed) {
        double x = this.Left + (double)e.GetPosition(this).X - (double)rectangle1.Margin.Left;
        double y = this.Top + (double)e.GetPosition(this).Y - (double)rectangle1.Margin.Top;
        rectangle1.Margin = new Thickness(x, y, rectangle1.Margin.Right, rectangle1.Margin.Bottom);
    }
}

解决方案

You want to use adorners to achieve dragging, resizing, rotating, etc.
