Python QMessageBox在DetailedText中防止换行
我正在尝试构建一个消息对话框,显示对我的UI的影响的详细信息。这个列表足够长,需要一个滚动条,但是文本足够长,我希望行不要被打断。QMessage对话框的大小似乎很难调整,因为它会根据其内容进行计算。有没有办法“鼓励那个详细的方框来防止断线?” 或者,允许调整QMessageBox的大小Python QMessageBox在DetailedText中防止换行,python,qmessagebox,qt.py,Python,Qmessagebox,Qt.py,我正在尝试构建一个消息对话框,显示对我的UI的影响的详细信息。这个列表足够长,需要一个滚动条,但是文本足够长,我希望行不要被打断。QMessage对话框的大小似乎很难调整,因为它会根据其内容进行计算。有没有办法“鼓励那个详细的方框来防止断线?” 或者,允许调整QMessageBox的大小 impacts = [] # Create Impacts for i in range(0, 100): impacts.append(" This is a text can be a l

您必须获取QTextEdit并禁用换行:
from Qt.QtCore import Qt
from Qt.QtWidgets import QApplication, QMessageBox, QTextEdit
if __name__ == "__main__":
import sys
app = QApplication(sys.argv)
impacts = []
# Create Impacts
for i in range(0, 100):
impacts.append(
" This is a text can be a little long but not too long impact {}".format(i)
)
# CreateDialog
diffBox = QMessageBox()
diffBox.setWindowTitle("Test")
diffBox.setInformativeText(
"Impacts have been found, and this message is long but not too long as well but independent of the list"
)
diffBox.setDetailedText("changes:\n\n" + "\n".join(impacts))
# Add Buttons
diffBox.addButton("Apply", QMessageBox.AcceptRole)
diffBox.setStandardButtons(QMessageBox.Cancel)
diffBox.setSizeGripEnabled(True)
te = diffBox.findChild(QTextEdit)
if te is not None:
te.setLineWrapMode(QTextEdit.NoWrap)
te.parent().setFixedWidth(
te.document().idealWidth()
+ te.document().documentMargin()
+ te.verticalScrollBar().width()
)
result = diffBox.exec_()
哇,太好了,有什么办法可以调整大小以适应吗?@Jim我知道你的问题是删除换行造成的不必要的换行符,对吗?如果是这样,如果你还有其他问题,那么就创建另一篇文章。这个问题的目的是防止换行符,以便文本以全宽显示
