PQYT使QGridLayout可滾動-有解無憂

我想知道是否可以將 QScrollArea 添加到 QGridLayout？以下是我的嘗試，但是它總是因錯誤而失敗。

TypeError: setWidget(self, QWidget): argument 1 has unexpected type 'QGridLayout'

這種方法是否僅適用于組合框和串列框？我基本上是將 QPixmap 影像傳遞到需要滾動的 QGridLayout 中。非常感謝您的任何幫助。

import sys

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class PicClip(QWidget):

    def __init__(self):
        super().__init__()
        # Load image
        self.im = QPixmap("1.jpg")
        self.im1 = QPixmap("1.jpg")
        # Label 1
        self.label = QLabel()
        self.label.setPixmap(self.im)
        # Label 2
        self.label1 = QLabel()
        self.label1.setPixmap(self.im1)
        # Make Grid
        self.grid = QGridLayout()
        # Create widgets to grid
        self.grid.addWidget(self.label, 0, 1, alignment=Qt.AlignCenter)
        self.grid.addWidget(self.label1, 1, 1, alignment=Qt.AlignCenter)
        # Set layout of Grid
        self.setLayout(self.grid)
        # Scroll 
        scroll = QScrollArea()
        scroll.setWidget(self.grid)
        scroll.setWidgetResizable(True)
        # Show 
        self.show()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = PicClip()
    sys.exit(app.exec_())

uj5u.com熱心網友回復：

self.grid是布局，您正在嘗試使用setWidget函式添加布局。setWidget函式只得到QWidget

簡單的技巧是添加包裝器QWidget并設定self.grid為其布局

import sys

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class PicClip(QMainWindow): # I modified this line to show window properly

    def __init__(self):
        super().__init__()
        # Load image
        self.im = QPixmap("1.jpg")
        self.im1 = QPixmap("1.jpg")
        # Label 1
        self.label = QLabel()
        self.label.setPixmap(self.im)
        # Label 2
        self.label1 = QLabel()
        self.label1.setPixmap(self.im1)
        # Make Grid
        self.grid = QGridLayout()
        # Create widgets to grid
        self.grid.addWidget(self.label, 0, 1, alignment=Qt.AlignCenter)
        self.grid.addWidget(self.label1, 1, 1, alignment=Qt.AlignCenter)
        # Set layout of Grid
        self.setLayout(self.grid)
        # Scroll
        scroll = QScrollArea()
        # add wrapper widget and set its layout
        wrapper_widget = QWidget()
        wrapper_widget.setLayout(self.grid)
        scroll.setWidget(wrapper_widget)
        scroll.setWidgetResizable(True)
        # Show
        self.setCentralWidget(scroll)  # I modified this line to show window properly
        self.show()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = PicClip()
    sys.exit(app.exec_())
