libgdx - 如何使用包装文本获取Label [英] libgdx - how to get a Label with wrapped text

问题描述

我尝试了以下代码：

Label label = new Label(reallyLongString, skin);
label.setWrap(true);
label.setWidth(100); // or even as low as 10
table.add(label);
...

然而我得到的只是一条很宽的线屏幕。

and yet all I get is a very wide line that draws off the screen.

推荐答案

这与如何将标签放到合适的尺寸或滑块始终具有默认宽度。

您需要将该标签放入表中，并将正确的大小添加到标签所在表格的单元格中。

You need to put that label into a table and add the right size to the cell of the table where the label is.

UI小部件不设置自己的大小和位置。相反，父窗口小部件设置每个子项的大小和位置。窗口小部件提供父级可用作提示的最小，首选和最大大小。某些父窗口小部件（如Table）可以为如何调整子项的大小和位置提供约束。要在窗体中为窗口小部件指定特定大小，窗口小部件的最小，首选和最大大小将保持不变，并且在父窗口中设置大小约束。

UI widgets do not set their own size and position. Instead, the parent widget sets the size and position of each child. Widgets provide a minimum, preferred, and maximum size that the parent can use as hints. Some parent widgets, such as Table, can be given constraints on how to size and position the children. To give a widget a specific size in a layout, the widget's minimum, preferred, and maximum size are left alone and size constraints are set in the parent.

解决方案：

Label label = new Label(reallyLongString, skin);
label.setWrap(true);
label.setWidth(100); // or even as low as 10
table.add(label).width(10f);// <--- here you define the width
