下面的代码生成一个树视图节点,其中包含一个图标(来自.PNG文件Piconfolder''PiconName),后跟一个文本字符串Pheader。我想只为图标添加背景(与透明图标一起使用)
public static TreeViewItem CreateTreeViewItem(
string Pheader,
string PiconFolder,
string PiconName)
{
string iconFolder = PiconFolder;
string iconName = PiconName;
string header = Pheader;
TreeViewItem child = new TreeViewItem();
StackPanel pan = new StackPanel();
pan.Orientation = Orientation.Horizontal;
string fPath = System.IO.Path.Combine(iconFolder, iconName);
Image image = new Image();
image.Height = 16;
image.Width = 16;
image.Source = new BitmapImage(new Uri(fPath, uriKind.RelativeOrAbsolute));
pan.Children.Add(image);
pan.Children.Add(new TextBlock(new Run(" " + header)));
child.Header = pan;
}
替换
pan.Children.Add(image);
跟
var iconPanel = new Grid(); // or other panel
iconPanel.Background = Brushes.Blue;
iconPanel.Children.Add(image);
pan.Children.Add(iconPanel);
