在Qt软件中用QSS帮我写几个有3D感的按键

好的，以下是几个使用QSS实现3D效果的按钮样式：

1. 立体感按钮：

QPushButton {
    border: 1px solid #333;
    border-radius: 5px;
    padding: 5px;
    color: #fff;
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #666, stop: 1 #333);
    box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.5);
}

QPushButton:hover {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #999, stop: 1 #666);
}

QPushButton:pressed {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #333, stop: 1 #666);
    box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.5);
}

2. 凸起按钮：

QPushButton {
    border: 1px solid #333;
    border-top-color: #ccc;
    border-left-color: #ccc;
    border-radius: 5px;
    padding: 5px;
    color: #fff;
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #666, stop: 1 #333);
    box-shadow: 1px 1px 3px rgba(0, 0, 0, 0.5) inset;
}

QPushButton:hover {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #999, stop: 1 #666);
    border-top-color: #fff;
    border-left-color: #fff;
}

QPushButton:pressed {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #333, stop: 1 #666);
    box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.5) inset;
}

3. 漂浮按钮：

QPushButton {
    border: 1px solid #333;
    border-radius: 5px;
    padding: 5px;
    color: #fff;
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #666, stop: 1 #333);
    box-shadow: 0px 3px 10px rgba(0, 0, 0, 0.5);
}

QPushButton:hover {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #999, stop: 1 #666);
    box-shadow: 0px 3px 5px rgba(0, 0, 0, 0.5);
}

QPushButton:pressed {
    background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #333, stop: 1 #666);
    box-shadow: 0px 1px 2px rgba(0, 0, 0, 0.5);
}

这些样式可以通过调整颜色和阴影参数来适应不同的场景，希望能帮到您。
