QFormLayout [중복]에서 clicked.connect () QPushButton 수 없습니다.
Dec 22 2020
이것은 전체 코드입니다. 왜 clicked.connect를 내 마음에 사용할 수 없는지 모르겠습니다. 여전히 논리 '-'이지만 왜 !!! ???
from PyQt5 import QtGui
from PyQt5.QtWidgets import QApplication, QWidget, QScrollArea, QVBoxLayout, QGroupBox, QLabel, QPushButton, QFormLayout
import sys
class Window(QWidget):
def __init__(self, val):
super().__init__()
self.title = "PyQt5 Scroll Bar"
self.top = 200
self.left = 500
self.width = 400
self.height = 300
self.setWindowIcon(QtGui.QIcon("icon.png"))
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
formLayout = QFormLayout()
groupBox = QGroupBox("This Is Group Box")
labelLis = []
comboList = []
for i in range(val):
labelLis.append(QLabel("Label"))
comboList.append(QPushButton("Click Me").clicked.connect(print("hello")))
formLayout.addRow(labelLis[i], comboList[i])
groupBox.setLayout(formLayout)
scroll = QScrollArea()
scroll.setWidget(groupBox)
scroll.setWidgetResizable(True)
scroll.setFixedHeight(400)
layout = QVBoxLayout(self)
layout.addWidget(scroll)
self.show()
App = QApplication(sys.argv)
window = Window(30)
sys.exit(App.exec())
그리고 여기에 오류가 있습니다. 모든 항목을 클릭 할 수 있도록하고 싶지만 왜 이런 일이 발생하는지 모르겠습니다. "D
for i in range(val):
labelLis.append(QLabel("Label"))
comboList.append(QPushButton("Click Me").clicked.connect(print("hello")))
formLayout.addRow(labelLis[i], comboList[i])
groupBox.setLayout(formLayout)
이 코드는 작동하지 않습니다.
comboList.append(QPushButton("Click Me").clicked.connect(print("hello")))

comboList.append(QPushButton("Click Me").clicked.connect(self.hello)
오류가 발생하는 이유를 모르겠습니다.
하지만 나는 할 것이다
qbutton = QPushButton("Click Me")
qbutton.clicked.connect(self.hello)
결과
