如何增加此滑块手柄的高度:
如图所示:
子类化 QAbstractSlider 是唯一的方法吗?
这是我的代码中的样式表:
QSlider::groove:horizontal {
border: 1px solid #999999;
height: 32px; /* the groove expands to the size of the slider by default. by giving it a height, it has a fixed size */
background: qlineargradient(x1:0, y1:0, x2:0, y2:1,
stop:0 #B1B1B1, stop:1 #c4c4c4);
margin: 2px 0;
}
QSlider::handle:horizontal {
background: qlineargradient(x1:0, y1:0, x2:1, y2:1,
stop:0 #b4b4b4, stop:1 #8f8f8f);
border: 1px solid #5c5c5c;
width: 40px;
margin: -20px 0; /* handle is placed by default on the contents rect of the groove. Expand outside the groove */
border-radius: 3px;
}
使用此样式表:
.QSlider {
min-height: 68px;
max-height: 68px;
background: #5F4141;
}
.QSlider::groove:horizontal {
border: 1px solid #262626;
height: 5px;
background: #393939;
margin: 0 12px;
}
.QSlider::handle:horizontal {
background: #22B14C;
border: 5px solid #B5E61D;
width: 23px;
height: 100px;
margin: -24px -12px;
}
它将产生以下结果:
请注意,通过将
min-height
和 max-height
设置为相同的值,滑块的高度将保持恒定。
