因此，作为输入，我得到了这样一个 JSON 对象数组。问题是：如何使用索引获取我需要的对象Java？我将这些数据作为字符串接收String。

鼠标悬停时，背景只在按钮文字后面发生变化，但按钮本身的边框明显变大了。

为什么会发生这种情况，我还没有弄清楚。我想改变按钮的整个背景，就像第二张图片一样（但是，背景必须是纯色的）。

鼠标光标在屏幕截图中不可见，但不在文本上，而是在按钮本身内

在此处输入图像描述

以下是styleSheet按钮：

QPushButton{
    background: rgba(0, 0,0,0);
    margin: 20, 20, 0, 0
}

QPushButton:hover{
    background:rgba(0, 0, 0,30)
}
