PyQt5：標簽在網格布局中從頂部和底部截斷

Question

我正在嘗試通過 for 循環向對話框 window 添加標簽。 理想情況下，我希望行高可以根據內容進行調整，這樣如果字符串是一行，則行高是一行，而如果字符串是 5 行，行會反映這一點。 這樣我可以通過所有內容向 go 添加滾動條。

相反，我在每個 label 的頂部和底部得到了這個奇怪的截斷：

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_()

我運行程序時的結果

關於關於固定寬度/高度的注釋，這是注釋掉固定寬度和高度的結果：

Answer 1

聽起來你想要一個 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_()
