PyQt5：标签在网格布局中从顶部和底部截断

Question

我正在尝试通过 for 循环向对话框 window 添加标签。 理想情况下，我希望行高可以根据内容进行调整，这样如果字符串是一行，则行高是一行，而如果字符串是 5 行，行会反映这一点。 这样我可以通过所有内容向 go 添加滚动条。

相反，我在每个 label 的顶部和底部得到了这个奇怪的截断：

from PyQt5 import QtWidgets

app = QtWidgets.QApplication([])

window = QtWidgets.QDialog()
grid = QtWidgets.QGridLayout()
window.setLayout(grid)

window.setFixedWidth(200)
window.setFixedHeight(600)

for label in range(5):
    label = QtWidgets.QLabel()
    label.setText(2 * "This is a label with slightly too much text for this little window. Therefore it would be great to wrap this text and have the row size be adjusted automatically.")
    label.setWordWrap(True)
    grid.addWidget(label)

    label2 = QtWidgets.QLabel()
    label2.setText(2 * "HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA")
    label2.setWordWrap(True)
    grid.addWidget(label2)

window.show()
app.exec_()

我运行程序时的结果

关于关于固定宽度/高度的注释，这是注释掉固定宽度和高度的结果：

Answer 1

听起来你想要一个 QScrollArea：

from PyQt5 import QtWidgets

app = QtWidgets.QApplication([])

window = QtWidgets.QScrollArea(widgetResizable=True)
widget = QtWidgets.QWidget()
window.setWidget(widget)
grid = QtWidgets.QGridLayout(widget)

window.setFixedWidth(200)
window.setFixedHeight(600)

for label in range(5):
    label = QtWidgets.QLabel()
    label.setText(2 * "This is a label with slightly too much text for this little window. Therefore it would be great to wrap this text and have the row size be adjusted automatically.")
    label.setWordWrap(True)
    grid.addWidget(label)

    label2 = QtWidgets.QLabel()
    label2.setText(2 * "HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA HABALABOBA")
    label2.setWordWrap(True)
    grid.addWidget(label2)

window.show()
app.exec_()
