libdgx如何设置TextButton的样式？

Question

Using the uiskin.json by default

It contains

com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle: {
default: { font: default-font, fontColor: white }
},
com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle: {
default: { down: default-round-down, up: default-round, font: default-font, fontColor: white     },
toggle: { down: default-round-down, up: default-round, checked: default-round-down, font:     default-font, fontColor: white, downFontColor: red }
},

--

skin = new Skin(Gdx.files.internal("data/uiskin.json"));
TextButton button = new TextButton("my button",skin);

if clicked, it will change color using button.setColor(Color.RED); This works well.

if clicked again, I want it to change back to the default style. I wrote the following but it causes an error

button.setStyle(new TextButton.TextButtonStyle());

The error is:

FATAL EXCEPTION GLThread 2812
java.lang.IllegalRuntimeException: Missing LabelStyleFont

I have the files default.fnt and default.png in my assets folder already. Please enlighten me!

您不需要做TextButton.getStyle（）来获取样式吗？
