在 WPF (C#) 中有一种方法可以动态设置工具提示的高度和宽度(在代码中的含义)。谢谢您的帮助。
System.Windows.Controls.Image td = new System.Windows.Controls.Image();
BitmapImage myBitmapImage = new BitmapImage();
myBitmapImage.BeginInit();
myBitmapImage.UriSource = new Uri(Directory.GetCurrentDirectory() + "/Homepage.jpg");
td.Width = 530;
td.Height = 392;
//myBitmapImage.DecodePixelWidth = 430;
//myBitmapImage.DecodePixelHeight = 292;
myBitmapImage.EndInit();
td.Source = myBitmapImage;
TextBlock textBlock = new TextBlock();
BrushConverter conv = new BrushConverter();
string strColor1 = bannerColor.SelectedItem.ToString();
strColor1 = strColor1.Substring(strColor1.IndexOf(' ') + 1);
SolidColorBrush col = conv.ConvertFromString(strColor1) as SolidColorBrush;
textBlock.Foreground = col;
textBlock.FontWeight = FontWeights.Bold;
textBlock.FontSize = 18;
textBlock.FontFamily = new System.Windows.Media.FontFamily("Tahoma");
textBlock.Width = 100;
textBlock.Height = 20;
textBlock.Text = "BACKUP";
textBlock.Margin = new Thickness(5, 5, 425, 367);
Grid toolTipPanel = new Grid();
toolTipPanel.Width = 530;
toolTipPanel.Height = 392;
toolTipPanel.Children.Add(td);
toolTipPanel.Children.Add(textBlock);
ToolTipService.SetToolTip(image1, toolTipPanel);
ToolTipService.SetShowDuration(image1, 999999999);`
