在 WPF 中以编程方式创建 ControlTemplate
如何以编程方式设置按钮的模板？
Polygon buttonPolygon = new Polygon();
buttonPolygon.Points = buttonPointCollection;
buttonPolygon.Stroke = Brushes.Yellow;
buttonPolygon.StrokeThickness = 2;
// create ControlTemplate based on polygon
ControlTemplate template = new ControlTemplate();
template.Childeren.Add(buttonPolygon); // This does not work! What's the right way?
//create button based on controltemplate
Button button = new Button();
button.Template = template;
所以我需要一种方法将我的多边形设置为按钮的模板。建议？
谢谢。
How can I programmatically set a button's template?
Polygon buttonPolygon = new Polygon();
buttonPolygon.Points = buttonPointCollection;
buttonPolygon.Stroke = Brushes.Yellow;
buttonPolygon.StrokeThickness = 2;
// create ControlTemplate based on polygon
ControlTemplate template = new ControlTemplate();
template.Childeren.Add(buttonPolygon); // This does not work! What's the right way?
//create button based on controltemplate
Button button = new Button();
button.Template = template;
So I need a way to set my Polygon as the button's template. Suggestions?
Thanks.

正式地，您应该为新的 ControlTemplate 创建 XAML 作为字符串，然后使用 XamlReader.Parse 将其具体化为 ControlTemplate 对象。
一种更结构化的方法是使用 FrameworkElementFactory 类 - 创建一个 FrameworkElementFactory 并将 ControlTemplate.VisualTree 设置为该 FEF。这为您提供了改进的类型安全性，并避免了写出对象树只是为了再次读入它的笨拙。然而，它已被正式弃用，如果您有一个复杂的模板，它可能会变得相当复杂。
请参阅 如何在代码中设置 WPF 数据模板树视图？这两种方法的示例——它们是在 DataTemplate 的上下文中编写的，但也适用于 ControlTemplate。
Officially, you should create the XAML for the new ControlTemplate as a string, then materialise it as a ControlTemplate object using XamlReader.Parse.
A more structured way to do this is using the FrameworkElementFactory class -- create a FrameworkElementFactory and set ControlTemplate.VisualTree to that FEF. This gives you improved type safety and avoids the clunkiness of writing out an object tree just to read it in again. However, it is officially deprecated and can get rather complicated if you have a complicated template.
See How to setup a WPF datatemplate in code for a treeview? for examples of both approaches -- they are written in the context of a DataTemplate but will work for a ControlTemplate as well.
