我希望在BackgroundWorker进程在另一个线程中运行时显示沙漏光标并禁用该窗口。
这就是我正在做的事情:
Private Sub MyButton_Click(...)
Dim box As New AnotherWpfWindow()
box.Owner = Me
...
box.ShowDialog()
If (box.DialogResult.GetValueOrDefault = True) Then
Me.IsEnabled = False
Me.Cursor = Cursors.Wait
MyBackgroundWorker.RunWorkerAsync()
End If
End Sub
Private Sub MyBackgroundWorker_RunWorkerCompleted(...)
UpdateInterface()
Me.IsEnabled = True
Me.Cursor = Cursors.Arrow
End Sub
窗口会像我想要的那样被禁用,但光标仍然是箭头。我怎样才能使它成为等待光标?
根据这个问题似乎适用于vg1890:Disabling all but one control in a WPF window

另一种方法是全局更改光标,是..
Mouse.OverrideCursor = Cursors.Wait;
//Do something
//...
Mouse.OverrideCursor = null;

这里似乎发生的事情是WPF忽略了禁用窗口上的Cursor设置。以下解决方法似乎有效:不禁用窗口本身,而是禁用窗口的内容:
C#:
((UIElement)Content).IsEnabled = false;
Cursor = Cursors.Wait;
// and in RunWorkerCompleted handler:
((UIElement)Content).IsEnabled = true;
Cursor = Cursors.Arrow;
Visual Basic:
DirectCast(Content, UIElement).IsEnabled = False
Cursor = Cursors.Wait
' and in RunWorkerCompleted handler:'
DirectCast(Content, UIElement).IsEnabled = True
Cursor = Cursors.Arrow
