Get Mouse Position on Canvas (But NOT on window)?
Solution 1
Doesn't this work?
Point p = Mouse.GetPosition(canvas);
The position of the mouse pointer is calculated relative to the specified element with the upper-left corner of element being the point of origin,
Solution 2
Hi the important thing is the
NOT on the Window
the canvas is part of the window as well. one example:
- the Window.AllowsTransparency state is on true
- the Window.Background is #00000000 (completely transparent)
- the Window.Style is None
- the Window.State is Maximized and
- there are NO controls or elements on the window!
... so if you start the application you will see Nothing now tell me how to get the mouseposition on the screen in pixel
!Warning!
if you juse Mouse.GetPosition(this);
it will return x0 y0 every time
Solution 3
so I solved the Problem by using System.Windows.Forms.Control.MousePosition
it's a bit a mix of wpf and Windows.Forms but I've given up xD.
Sorry for yelling :/
To make it easy for me I made a Extension:
<DebuggerHidden> _
<System.Runtime.CompilerServices.Extension> _
Public Function toWfpPoint(p As System.Drawing.Point) As Point
Return new Point(p.X, p.Y)
End Function
Now I just can juse it like this:
Dim MousPos As Point = System.Windows.Forms.Control.MousePosition.toWfpPoint

I have a project in WPF 4 and vb.net 2010.
I have a canvas inside a window. The window is full screen, but the canvas is set to a solid 640x480 in the center of the window. I need to get the mouse position inside of the canvas, but NOT inside of the window. How do I do this?

CodeMouse92 about 13 yearsHmm. Apparently is does after all, yet trying to use those (set as variables) to set the left and top properties of an object on the same canvas is not working...
