我正在尝试在Box布局中显示带有滚动条的图像标签。 但是,滚动区域出现在错误的位置,大小错误。 你能告诉我我做错了吗?
import sys
from PyQt5 import QtCore
from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QPushButton, QLabel, QScrollArea
from PyQt5.QtGui import QPixmap
class ApplicationWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
main_widget = QWidget(self)
btn = QPushButton("Bye", self)
btn.clicked.connect(self.close)
img = QPixmap("1.jpg")
label = QLabel(main_widget)
label.setPixmap(img)
scrollArea = QScrollArea(main_widget)
scrollArea.setWidgetResizable(True)
scrollArea.setWidget(label)
l = QVBoxLayout(main_widget)
l.addWidget(label)
l.addWidget(btn)
self.setCentralWidget(main_widget)
def closeEvent(self, ce):
self.close()
if __name__ == '__main__':
app = QApplication(sys.argv)
aw = ApplicationWindow()
aw.show()
app.exec_()
结果是:
