QMessageBox在DetailedText中防止换行
QMessageBox在DetailedText中防止换行
提问于 2020-08-13 01:06:44
我正在尝试构建一个消息对话框，以显示对我的UI的影响的详细信息。这个列表足够长，需要一个滚动条，但文本足够长，我不希望行被打断。似乎改变QMessage对话框的大小很难，因为它根据其内容对其进行计算。有没有办法“鼓励详细的方框防止换行？”
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 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)
result = diffBox.exec_()

您必须获取QTextEdit并禁用线缆：
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_()
