如何在桌面空间中移动不规则的wpf窗口? [英] How do I moving an irregularly wpf window in desktop space?

问题描述

大家好，

我有一个带有Background ="{x:Null}"，AllowsTransparency ="True"和WindowStyle ="None"属性的WPF窗口，并且其中有一个对象，我想通过光标在桌面空间中用下面的鼠标移动此不规则窗口代码，但不能正常工作，有什么主意吗?

Hi everybody,

I have a WPF window with Background="{x:Null}", AllowsTransparency="True" and WindowStyle="None" properties and there is an object within it, I want moving this irregular window by cursor mouse in desktop space with below code, but not work correctly, is there any idea?

bool inDrag;
Point dragPoint;

private void Body3D_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    dragPoint = e.GetPosition(this);
    inDrag = true;
}

private void Body3D_MouseMove(object sender, MouseEventArgs e)
{
    if (inDrag)
    {
        Point pointMoveTo;

        // Find the current mouse position in screen coordinates.
        pointMoveTo = this.PointToScreen(e.GetPosition(this));

        // Compensate for the position the control was clicked.
        pointMoveTo.Offset(-dragPoint.X, -dragPoint.Y);

        // Compensate for the non-client region (title bar).
        // This code is not necessary if you explicitly hide the title bar
        //  by setting the form's BorderStyle to None.
        //pointMoveTo.Offset(0, -25);

        // Move the window.
        this.Top = pointMoveTo.X;
        this.Left = pointMoveTo.Y;
    }
}

private void Body3D_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    inDrag = false;
}

推荐答案

您不会相信，但这就是您所需要的:-):

You not gonna believe that, but this is all you need :-):

public partial class MyWindow : Window {

    //...

    protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) {
        base.OnMouseLeftButtonDown(e);
        this.DragMove(); //begin dragging mode
    } //...

} //class MyWindow

也就是说，它已经为您完成.请参阅 http://msdn.microsoft.com/en-us/library/system .windows.window.dragmove.aspx [ ^ ].
