/* CloseButton by David Peng
|
||
* 2020 10.20
|
||
* Version Beta 1.0
|
||
* 介绍：该控件是用于对话框的关闭按钮，只需指定父对象即可可自动回收。
|
||
* 使用方法：
|
||
* 1、new CloseButton(this); //这样会直接调用主题的关闭按钮。
|
||
* 2、new CloseButton(黑色图标路径,this); //这样会用一个黑色的'X'图标SVG，hover时会渲染成白色。
|
||
* 3、new CloseButton(黑色图标路径，白色图标路径,this) //这样会用两张图片来实现图标显示。
