Cursor = Cursors.None 用于代码中的弹出窗口

Question

我试图在弹出窗口的代码中将光标设置为无，但我无法让它工作。光标在弹出窗口上方时仍会显示。我究竟做错了什么？public void SubWindow_KeyDown(object sender, KeyEventArgs e)    {     if (e.Key == Key.Enter)     {         TextBlock popupText = new TextBlock();         popupText.Text = "Complete" ;         popupText.Background = Brushes.Transparent;         popupText.Foreground = Brushes.White;                   popupText.Width = 130;         popupText.FontSize = 30;         popupText.IsHitTestVisible = false;         popupText.Cursor = Cursors.None;         Popup Popup = new Popup();         Popup.AllowsTransparency = true;         Popup.PlacementRectangle = new Rect(1086, 16, 0, 0);         Popup.IsHitTestVisible = false;         Popup.Cursor = Cursors.None;         Popup_Text.Child = popupText;         Popup.IsOpen = true;    }

Answer 1

不要将 的IsHitTestVisible属性设置TextBlock为false：

TextBlock popupText = new TextBlock();

popupText.Text = "Complete";

popupText.Background = Brushes.Transparent;

popupText.Foreground = Brushes.White;

popupText.Width = 130;

popupText.Height = 130;

popupText.FontSize = 30;

//popupText.IsHitTestVisible = false;

popupText.Cursor = Cursors.None;

Popup Popup = new Popup();

//Popup.AllowsTransparency = true;

Popup.PlacementRectangle = new Rect(1086, 16, 0, 0);

Popup.IsHitTestVisible = false;

Popup.Cursor = Cursors.None;

Popup.Child = popupText;

Popup.IsOpen = true;

另请注意，您的应用程序只能在光标实际位于应用程序元素之一上时更改光标。透明的“背景”Popup不属于您的应用程序，因此Cursors.None仅当您将鼠标指针移到TextBlock.
