使用pyglet和ScrollableTextLayout渲染并滚动多行段落

Question

如何使用ScrollableTextLayout的功能通过pyglet显示和滚动多行字符串（包含“\ n”）？

STL crops what is display, and seems to be the most efficient way to implement scrolling.

但是我不知道如何使用它。这些文档对我来说并不太清楚。

SomeText：

string = "Some multiline \n text is contained within this string \n which must be rendered \n such that it is able to be scrolled through."

你创建一个这样的：

scroll_area = pyglet.text.layout.ScrollableTextLayout(my_text, width, height, multiline=True) 

然后使用view_x和view_y值选择滚动位置。

scroll_area.view_y = 30 # start 30 pixels down

设置view_y的不同值以垂直滚动。
