C# WPF 移动窗口

Question

我已将以下参数添加到我的Window：

WindowStyle="None"
WindowStartupLocation="CenterScreen"
AllowsTransparency="True"
ResizeMode="NoResize" Background="Transparent" 

现在我无法移动Window，所以我将以下部分代码添加到我的Window：

#region Window: Moving

private void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
}

#endregion

我还必须指定我的Window 中的XAML 代码如下（Window 看起来像Polygon）：

<Window Title="New Science"
    Height="588" Width="760" MinHeight="360" MinWidth="360"
    WindowStyle="None" WindowStartupLocation="CenterScreen"
    AllowsTransparency="True"
    ResizeMode="NoResize" Background="Transparent"
    xmlns:my="clr-namespace:Bourlesque.Lib.Windows.Media;assembly=Bourlesque.Lib.Windows.Media">
    <Grid>
        <my:UniPolygon DefaultRadiusIn="10" DefaultRadiusOut="10" Fill="#FF92C2F2" Name="m_tPlgOuter" Offset="0" Points="         0;26;;         10;19;10;;         10;0;;         265;0;20;;         290;20;20;;          -60,1;20;3;;         -60,1;5;10;;         -40,1;5;10;;         -40,1;20;2.5;;          -35,1;20;2.5;;         -35,1;5;10;;         -15,1;5;10;;         -15,1;20;3;;          0,1;20;;         0,1;0,1;;         0;0,1;;       " Stretch="None" Stroke="#FF535353" StrokeThickness="0.1" />
    </Grid>
</Window>

我想知道我应该怎么做才能使Window 改变它在鼠标拖动时的位置以及添加什么来调整窗口大小，条件是我将添加的控件和其他东西也会调整大小（我有发现此代码可调整大小，我想知道是否合适here)。

Answer 1

我使用了 MouseDown 事件：

<Window .....
     MouseDown="Window_MouseDown"  >

使用此代码：

  private void Window_MouseDown(object sender, MouseButtonEventArgs e)
  {
     if(e.ChangedButton == MouseButton.Left)
        this.DragMove();
  }

找到一个例子： http://cloudstore.blogspot.com.br/2008/06/moving-wpf-window-with-windowstyle-of.html

无论如何，要在我在项目中使用的 WinForms 中移动窗口，如果您遇到问题，以下代码可能会很有用：

private bool clicado = false;
private Point lm = new Point();
void PnMouseDown(object sender, MouseEventArgs e)
{
    clicado = true;
    this.lm = MousePosition;
}

void PnMouseUp(object sender, MouseEventArgs e)
{
    clicado = false;
}

void PnMouseMove(object sender, MouseEventArgs e)
{
    if(clicado)
    {
        this.Left += (MousePosition.X - this.lm.X);
        this.Top += (MousePosition.Y - this.lm.Y);
        this.lm = MousePosition;
    }
}

答案的代码很好，但有问题。它会让你的移动失去控制。

试试我的修改：

private bool clicado = false;
private Point lm = new Point();
void PnMouseDown(object sender, System.Windows.Input.MouseEventArgs e)
{
    clicado = true;
    this.lm = System.Windows.Forms.Control.MousePosition;
    this.lm.X = Convert.ToInt16(this.Left) - this.lm.X;
    this.lm.Y = Convert.ToInt16(this.Top) - this.lm.Y;
}

void PnMouseUp(object sender, System.Windows.Input.MouseEventArgs e)
{
    clicado = false;
}

void PnMouseMove(object sender, System.Windows.Input.MouseEventArgs e)
{
    if (clicado)
    {
        this.Left = (System.Windows.Forms.Control.MousePosition.X + this.lm.X);
        this.Top = (System.Windows.Forms.Control.MousePosition.Y + this.lm.Y);
    }
}

它会让你的移动棒对准你的光标。(///▽///)

@Marcio WPF 中没有 Windows.Forms。

我让这个版本与 WPF 一起工作（稳定），

private bool clicked = false;
private Point lmAbs = new Point();
void PnMouseDown(object sender, System.Windows.Input.MouseEventArgs e)
{
  clicked = true;
  this.lmAbs = e.GetPosition(this);
  this.lmAbs.Y = Convert.ToInt16(this.Top) + this.lmAbs.Y;
  this.lmAbs.X = Convert.ToInt16(this.Left) + this.lmAbs.X;
}

void PnMouseUp(object sender, System.Windows.Input.MouseEventArgs e)
{
  clicked = false;
}

void PnMouseMove(object sender, System.Windows.Input.MouseEventArgs e)
{
  if (clicked)
  {
    Point MousePosition = e.GetPosition(this);
    Point MousePositionAbs = new Point();
    MousePositionAbs.X = Convert.ToInt16(this.Left) + MousePosition.X;
    MousePositionAbs.Y = Convert.ToInt16(this.Top) + MousePosition.Y;
    this.Left = this.Left + (MousePositionAbs.X - this.lmAbs.X);
    this.Top = this.Top + (MousePositionAbs.Y - this.lmAbs.Y);
    this.lmAbs = MousePositionAbs;
  }
}

亲切的问候，

我已经尝试了另一种解决方案并成功了（但不确定它是否最正确）

private void GridOfWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        var move = sender as System.Windows.Controls.Grid;
        var win = Window.GetWindow(move);
        win.DragMove();
    }

其中 GridOfWindow 是网格的名称

<Grid x:Name="GridOfWindow" MouseLeftButtonDown="GridOfWindow_MouseLeftButtonDown">
