[已解决]我想设置QTextEdit文档的大小(例如8.5 x 11或3 x 5)。如果用户缩小视图,则应显示水平滚动条。当用户缩小视图时,我找不到停止换行的设置。如果我完全停止换行,则将忽略所有页面尺寸设置。

最佳答案
实际上,将linewrapmode设置为FixedPixelWidth
即可实现所需功能,即出现水平滚动条,并且将行包装在固定位置。我不知道为什么您的示例(以及此处)中的FixedColumnWidth
没有给出类似的结果。
例:
from PySide import QtGui, QtCore
app = QtGui.QApplication([])
window = QtGui.QWidget()
layout = QtGui.QVBoxLayout(window)
edit = QtGui.QTextEdit('jfdh afdhgfkjg fdnvfh vklkfjvkflj lddkl ljklfjkl jvkldjfkvljfgvjldf ll dl dljvklj ljljlbl llkb jbgl')
edit.setLineWrapColumnOrWidth(200)
edit.setLineWrapMode(QtGui.QTextEdit.FixedPixelWidth)
layout.addWidget(edit)
window.show()
app.exec_()
关于python - 调整大小后,QTextEdit不显示水平滚动条,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/25839669/
