我如何添加一个的FlowDocument到StackPanel的？ [英] How can I add a FlowDocument to a StackPanel?

问题描述

我创建了下面的类为了有一个简单的方法显示的格式文本的WPF文档中

然而，这种解决方案返回的FlowDocument ，然后我有麻烦的整合此FlowDocument的在我目前的应用程序中，我只需添加< STRONG>的TextBlocks 以StackPanels和WrapPanels和边框等。

我怎么能说我创建的FlowDocument对象添加到现有StackPanels，边框和WrapPanels？

解决方案

如果你换一个FlowDocumentReader里你的FlowDocument，那么你可以把它添加到面板或边框：

 的StackPanel SP =新的StackPanel（）; 
边境BD =新的边界（）; 
的FlowDocument FD = FlowDocumentParser.GetFlowDocument（你想{I：总是}使用这个库，它既是{B：容易}和{A：直截了当}。以格式的文档下面是一些例子{乙：驼峰}字符串：{EX：名字}，{EX：名字}，{如：标题}和{例如：allowUserToFilterRows}）。 
 FlowDocumentReader FDR =新FlowDocumentReader（）; 
 fdr.Document = FD; 
 
 sp.Children.Add（FDR）; 
 bd.Child = FDR; 
  

I created the following class in order to have an easy way to display formatted text in a WPF document.

However this solution returns a FlowDocument, and I am having trouble integrating this FlowDocument in my current application in which I was simply adding TextBlocks to StackPanels and WrapPanels and Borders, etc.

How can I add the FlowDocument objects that I create to my existing StackPanels, Borders, and WrapPanels?

解决方案

If you wrap your FlowDocument inside a FlowDocumentReader then you can add it to the panel or border:

StackPanel sp = new StackPanel();
Border bd = new Border();
FlowDocument fd = FlowDocumentParser.GetFlowDocument("You want to {i:always} use this library so it is both {b:easy} and {b:straight-forward} to format documents. Here are some examples of {b:camel-case} strings: {ex:firstName}, {ex:lastName}, {ex:title}, and {ex:allowUserToFilterRows}.");
FlowDocumentReader fdr = new FlowDocumentReader();
fdr.Document = fd;

sp.Children.Add(fdr);
bd.Child = fdr;
