java - 为什么我的 Libgdx ScrollPane 不水平滚动？

Question

您好，我正在尝试在 libgdx 游戏中构建水平滚动屏幕，但由于某种原因只能使其垂直滚动而不是水平滚动。虽然 ScrollPane 听起来很简单，但由于某种原因我并不完全理解它，但是这里的滚动片尾示例对我有一点帮助。

我有一个表格，并向其中添加了几行文本。该表格与屏幕的大小相匹配，并且还包含一个名为 scroller 的 ScrollPane，它填充表格的大小。我猜测，由于文本行不适合屏幕，因此 scroller，scroller 自动允许在制作人员名单示例中垂直滚动？但是，当我将文本更改为一长行文本而不是新行时，scroller 不允许我水平滚动以查看所有文本，这是为什么？文本肯定超出了scroller 宽度吗？

scrollTable = new Table();    //create table
scrollTable.add(text);    //add a long line of text bigger than screen
scrollTable.row();
scrollTable.add(text2);
scrollTable.row();
scrollTable.add(text3);
scroller = new ScrollPane(scrollTable);  //create the ScrollPane

Table table = new Table();
table.setFillParent(true);
table.add(scroller).fill().expand();
//scroller.setWidth(500);
//scroller.setScrollingDisabled(false, true);
stage.addActor(table);

private static final String reallyLongString = 
"This is a really long string that has lots of lines and repeats itself over and over again This is a really long string that has" +
" lots of lines and repeats itself over and over again This is a really long string that has lots of lines and repeats itself over and over"+
" again This is a really long string that has lots of lines and repeats itself over and over again"+
" This is a really long string that has lots of lines and repeats itself over and over again This is a really long string that has lots"+
" of lines and repeats itself over and over again";
//This is my long string of text.

试试这个:

Table table = new Table();
ScrollPane scroll = new ScrollPane(table);
