我试图在PyQt的QScrollArea中添加一堆小部件,但似乎无法正常工作。
我想要做的是从列表中获取一些信息,并将其添加到QScrollArea中,但它仅显示列表中的最后一项。我还是python和PyQt的新手,如果问题很愚蠢,我深表歉意,
资源:
class Window(QFrame):
def __init__(self):
super(Window,self).__init__()
self.setStyle(QStyleFactory.create('Cleanlooks'))
self.setGeometry(300, 300, 600, 600)
self.setWindowTitle("Reddit")
self.show()
self.mainWindow()
def mainWindow(self):
self.submissionLayout = QVBoxLayout()
self.scrollArea = QScrollArea()
self.scrollArea.setWidgetResizable(True)
self.submissionLayout.addWidget(self.scrollArea)
self.setLayout(self.submissionLayout)
#to handle all the api calls using praw
self.x = RedditApi()
self.printSubmissions()
def printSubmissions(self):
#Gets the list of all submission titles to be displayed
#TO DO: Get and add other things like points and comments
self.submissions = self.x.showSubmissions()
for submission in self.submissions:
self.subcard = QVBoxLayout()
self.subcard.addStretch()
self.subtitle=QLabel()
print(submission)
self.subtitle.setText(submission)
self.subcard.addWidget(self.subtitle)
self.card = QWidget()
self.card.setLayout(self.subcard)
self.scrollArea.setWidget(self.card)
if __name__ == '__main__':
app = QApplication([])
window = Window()
sys.exit(app.exec_())
最佳答案
一个QScrollArea只能包含一个小部件,那么如何在QScrollArea中放置几个?在Qt中,QWidget也可以用作容器,因此在这种情况下,您必须创建一个布局稳定的content_widget,并在该布局中放置小部件。另一方面,通常在for循环中,不建议创建属性。
from PyQt5 import QtCore, QtGui, QtWidgets
class Window(QtWidgets.QFrame):
def __init__(self):
super(Window,self).__init__()
self.setStyle(QtWidgets.QStyleFactory.create('Cleanlooks'))
self.setGeometry(300, 300, 600, 600)
self.setWindowTitle("Reddit")
self.mainWindow()
self.show()
def mainWindow(self):
submissionLayout = QtWidgets.QVBoxLayout(self)
scrollArea = QtWidgets.QScrollArea(widgetResizable=True)
submissionLayout.addWidget(scrollArea)
content_widget = QtWidgets.QWidget()
scrollArea.setWidget(content_widget)
self.scroll_layout = QtWidgets.QVBoxLayout(content_widget)
#to handle all the api calls using praw
self.x = RedditApi()
self.printSubmissions()
def printSubmissions(self):
#Gets the list of all submission titles to be displayed
#TO DO: Get and add other things like points and comments
self.submissions = self.x.showSubmissions()
for submission in self.submissions:
card = QtWidgets.QWidget()
subtitle = QtWidgets.QLabel(submission)
subcard = QtWidgets.QVBoxLayout(card)
subcard.addStretch()
subcard.addWidget(subtitle)
self.scroll_layout.addWidget(card)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication([])
w = Window()
sys.exit(app.exec_())
