You'd think that word wrapping on a QLabel should be simple, just apply setWordWrap(True) to the label and PyQt will figure out the rest. However, in my program, that doesn't happen. The wrap occurs significantly earlier than the end of the widget, while also not having a decent enough height to actually show the full text. I've attached a minimally reproducible example to show what I mean. If you comment out the line self.content.setWordWrap(True), you can see that everything works as expected (with the long text running off the window, requiring a scrollbar.
from PyQt5.QtGui import *
from PyQt5.QtCore import *
class MainWindow(QWidget):
def __init__(self, *args, **kwargs):
## Set up Window layout
super(MainWindow, self).__init__(*args, **kwargs)
self.setLayout(QGridLayout())
self.setGeometry(300, 50, 1500, 700)
self.layout().setColumnStretch(0, 1)
self.layout().setColumnStretch(1, 2)
leftGroup = QGroupBox('Left Group')
self.layout().addWidget(leftGroup, 0, 0)
rightGroup = QGroupBox('Right Group')
self.layout().addWidget(rightGroup, 0, 1)
rightLayout = QVBoxLayout(rightGroup)
rightLayout.addWidget(EventsWidget(False, {'first': {'Date': '762', 'Content': 'Documented in the Fulda foundation book'},
'second': {'Date': '10/28/1485', 'Content': 'Here is a super long message to test how the display works when this has a lot of content.'
'Let us hope the widget handles the long text well or else it will be difficult to do the'
'reformatting manually. I have faith since this is not a normal QLineEdit, but a QPlainTextEdit'}}))
class EventsWidget(QGroupBox):
def __init__(self, edit, event_list):
super().__init__('Events')
self.setLayout(QVBoxLayout())
self.event_list = event_list # The dict of events, key: uuid, data: date, content
scrollWidget = QWidget()
scrollWidget.layout = QVBoxLayout()
scrollWidget.setLayout(scrollWidget.layout)
for e in self.event_list:
event_data = self.event_list[e]
scrollWidget.layout.addWidget(EventWidget(edit, event_data['Date'], event_data['Content']))
scrollWidget.layout.addStretch(1)
## Create scrolling mechanics
scroll = QScrollArea()
scroll.setWidget(scrollWidget)
scroll.setWidgetResizable(True)
self.layout().addWidget(scroll)
class EventWidget(QWidget):
def __init__(self, edit, date, content):
super().__init__()
self.setLayout(QGridLayout())
margin = 0
self.layout().setContentsMargins(margin, margin, margin, margin)
if edit:
self.date = QLineEdit(date)
self.content = QPlainTextEdit(content)
else:
self.date = QLabel(date)
self.date.setFixedWidth(75)
self.content = QLabel(content)
self.content.setWordWrap(True)
self.layout().addWidget(self.date, 0, 0, alignment=Qt.AlignHCenter)
self.layout().addWidget(self.content, 0, 1, alignment=Qt.AlignLeft)
self.layout().setColumnStretch(1, 1)
if __name__ == '__main__':
## Creates a QT Application
app = QApplication([])
## Creates a window
window = MainWindow()
## Shows the window
window.show()
app.exec_()
I appreciate any and all suggestions for what I'm doing wrong.
Here's an image of what the label looks like with word wrapping on:
