问题描述
我希望能够访问该鼠标光标是否在我的应用程序的窗口的坐标。
当我使用Mouse.Capture( IInputElement)或UIElement.CaptureMouse(),既无法捕捉鼠标和返回false。
什么可能是我的问题?
我的窗口CS文件如下:
使用System.Windows;
使用System.Windows.Input;
命名空间ScreenLooker
{
///<总结> $ B $为Window1.xaml
///< b ///交互逻辑; /总结>
公共部分类窗口1:窗口
{
公共窗口1()
{
的InitializeComponent();
布尔bSuccess = Mouse.Capture(本);
bSuccess = this.CaptureMouse();
}
保护覆盖无效的OnMouseMove(MouseEventArgs E)
{
tbCoordX.Text = e.GetPosition(本).X.ToString();
tbCoordY.Text = e.GetPosition(本).Y.ToString();
//System.Drawing.Point oPoint = System.Windows.Forms.Cursor.Position;
//tbCoordX.Text = oPoint.X.ToString();
//tbCoordY.Text = oPoint.Y.ToString();
base.OnMouseMove(E);
}
}
}
>传递给必须可见和已启用
尝试把Mouse.Capture在加载
事件处理程序,例如:
在XAML:
<窗口... ..标题=我的窗口加载=Window_Loaded>
:
< /窗GT;
在代码:
私人无效Window_Loaded(对象发件人,RoutedEventArgs E)
{
变种b = Mouse.Capture(本);
}
我之前没有捕捉整个窗口,所以不知道它是如何将工作。 ,它的典型用法是
- 的MouseDown: - 电话
Mouse.Capture()
在子控件 - 的MouseMove: - 过程X和鼠标ŸCOORDS
- 的MouseUp: - 调用
Mouse.Capture( NULL)
来清除鼠标事件捕获。
I want to be able to access the coordinates of the mouse whether or not the cursor is over the window of my application.
When I use Mouse.Capture(IInputElement) or UIElement.CaptureMouse(), both fail to capture the mouse and return false.
What might be my problem?
The cs file for my window is as follows:
using System.Windows;
using System.Windows.Input;
namespace ScreenLooker
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
bool bSuccess = Mouse.Capture(this);
bSuccess = this.CaptureMouse();
}
protected override void OnMouseMove(MouseEventArgs e)
{
tbCoordX.Text = e.GetPosition(this).X.ToString();
tbCoordY.Text = e.GetPosition(this).Y.ToString();
//System.Drawing.Point oPoint = System.Windows.Forms.Cursor.Position;
//tbCoordX.Text = oPoint.X.ToString();
//tbCoordY.Text = oPoint.Y.ToString();
base.OnMouseMove(e);
}
}
}
The control passed to Mouse.Capture()
needs to be Visible and Enabled.
Try putting the Mouse.Capture in the Loaded
event handler, e.g.
In XAML:
<Window ... .. .. Title="My Window" loaded="Window_Loaded">
...
</Window>
In Code:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
var b = Mouse.Capture(this);
}
I've not captured the whole window before, so not sure about how it will work. The typical usage of it is.
- MouseDown:- call
Mouse.Capture()
on child control - MouseMove:- Process X and Y coords of mouse
- MouseUp:- call
Mouse.Capture(null)
to clear mouse event capture.
