Examples
The following handler captures or releases mouse capture according to mouse button states. The example shows how to use captured mouse movement for alternative purposes other than moving the mouse pointer in the UI.
private void MouseDownHandler(object sender, MouseButtonEventArgs e)
{
ContentElement el = (ContentElement)sender;
if (!el.IsEnabled) return;
e.Handled = true;
el.CaptureMouse();
_point = e.MouseDevice.GetPosition(el);
}
private void MouseUpHandler(object sender, MouseButtonEventArgs e)
{
ContentElement el = (ContentElement)sender;
if (!el.IsEnabled) return;
e.Handled = true;
el.ReleaseMouseCapture();
}
Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
Dim el As ContentElement = CType(sender, ContentElement)
If Not el.IsEnabled Then
Return
End If
e.Handled = True
el.CaptureMouse()
_point = e.MouseDevice.GetPosition(el)
End Sub
Private Sub MouseUpHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
Dim el As ContentElement = CType(sender, ContentElement)
If Not el.IsEnabled Then
Return
End If
e.Handled = True
el.ReleaseMouseCapture()
End Sub
