Button介绍

[英]A button is a Table with a checked state and additional ButtonStyle fields for pressed, unpressed, and checked. Each time a button is clicked, the checked state is toggled. Being a table, a button can contain any other actors.

The button's padding is set to the background drawable's padding when the background changes, overwriting any padding set manually. Padding can still be set on the button's table cells.

ChangeEvent is fired when the button is clicked. Cancelling the event will restore the checked button state to what is was previously.

The preferred size of the button is determined by the background and the button contents.
[中]按钮是具有选中状态的表，以及用于按下、未按下和选中的其他按钮样式字段。每次单击按钮时，都会切换选中状态。作为一个表，按钮可以包含任何其他参与者。
当背景更改时，按钮的填充设置为背景可绘制的填充，手动覆盖任何填充设置。仍然可以在按钮的表格单元格上设置填充。
单击按钮时激发ChangeEvent。取消事件将使选中的按钮状态恢复到以前的状态。
按钮的首选大小由背景和按钮内容决定。

private void initialize () {

  addListener(clickListener = new ClickListener() {
    public void clicked (InputEvent event, float x, float y) {

  });
}

/** Toggles the checked state. This method changes the checked state, which fires a {@link ChangeEvent} (if programmatic change
 * events are enabled), so can be used to simulate a button click. */
