Python学习笔记之PyQt5布局 - BoxLayout & GridLayout

1.BOX布局

import sys
from PyQt5.QtWidgets import (QWidget, QPushButton,
    QHBoxLayout, QVBoxLayout, QApplication)


class BoxLayout(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()


    def initUI(self):

        okButton = QPushButton("OK")
        cancelButton = QPushButton("Cancel")

        hbox = QHBoxLayout()
        hbox.addStretch(1)
        hbox.addWidget(okButton)
        hbox.addWidget(cancelButton)

        vbox = QVBoxLayout()
        vbox.addStretch(1)
        vbox.addLayout(hbox)

        self.setLayout(vbox)

        self.setGeometry(300, 300, 300, 150)
        self.setWindowTitle('Buttons')
        self.show()


if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = BoxLayout()
    sys.exit(app.exec_())

2. 网格布局

import sys
from PyQt5.QtWidgets import (QWidget, QLabel, QLineEdit,
    QTextEdit, QGridLayout, QApplication)

class GridLayout(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()


    def initUI(self):

        title = QLabel('Title')
        author = QLabel('Author')
        review = QLabel('Review')

        titleEdit = QLineEdit()
        authorEdit = QLineEdit()
        reviewEdit = QTextEdit()

        grid = QGridLayout()
        grid.setSpacing(10)

        grid.addWidget(title, 1, 0)
        grid.addWidget(titleEdit, 1, 1)

        grid.addWidget(author, 2, 0)
        grid.addWidget(authorEdit, 2, 1)

        grid.addWidget(review, 3, 0)
        grid.addWidget(reviewEdit, 3, 1, 5, 1)

        self.setLayout(grid)

        self.setGeometry(300, 300, 350, 300)
        self.setWindowTitle('PyQt5 - GridLayout')
        self.show()


if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = GridLayout()
    sys.exit(app.exec_())
