QHBoxLayout是一个Qt库中的布局管理器,主要用于水平方向的控件排列。如果你想要在一个QHBoxLayout容器中添加边框,你可以直接设置容器本身的样式或者给其中的每个添加了边框的控件单独设置样式。
以下是在 PyQt 中如何设置QHBoxLayout容器有边框的一个简单示例:
```python
from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QLabel
from PyQt5.QtGui import QPainter, QPen
class Example(QWidget):
def __init__(self):
super().__init__()
self.layout = QHBoxLayout()
self.setLayout(self.layout)
# 给QHBoxLayout设置边框
self.layout.setContentsMargins(10, 10, 10, 10) # 设置外边距(左、上、右、下)
self.layout.setBorderPolicy(QLayout.SetBorder) # 设置边界策略为有边框
self.layout.setSpacing(5) # 设置控件之间的间距
for i in range(3): # 添加几个带边框的标签
label = QLabel(f"Label {i+1}")
painter = QPainter(label)
pen = QPen(Qt.black, 2) # 创建边框笔刷
painter.setPen(pen) # 设置标签的画布笔刷为边框颜色和宽度
painter.drawRect(label.rect()) # 绘制矩形边框
self.layout.addWidget(label)
if __name__ == "__main__":
app = QApplication([])
ex = Example()
ex.show()
app.exec_()
```
在这个例子中,我们设置了QHBoxLayout的外边距,并通过`setBorderPolicy`指定它有一个边框。然后,对每个添加到布局的标签单独绘制了一个矩形边框。
