Question

当我放大GUI窗口时，我希望所有小部件的长度（水平）都改变。现在，当我放大窗口时，只有行编辑会更改大小。最重要的是，我希望按钮和组合框更长。

import sys
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QGridLayout, QWidget, QListWidget, QLineEdit, QHBoxLayout, QPushButton


class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        centralWidget = QWidget()
        self.setCentralWidget(centralWidget)
        self.Search_Bar = QLineEdit(placeholderText="Search")
        self.Button = QPushButton('button')
        layout = QHBoxLayout(centralWidget)
        layout.addWidget(self.Button)
        layout.addWidget(self.Search_Bar)



if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())
