PyQt5布局大全

今天我们一起来看下 PyQt5的布局，我之前是做Android开发的在android里面也有布局这一说简单的来说，主要是

1，线性布局

2，相对布局

3，表格布局

4，帧布局

5，绝对布局

其实在PyQt5中，这些都是类似的

1，PyQt5的绝对布局

import sys
from PyQt5.QtWidgets import QWidget, QLabel, QApplication
calss Example(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        lbl1 = QLabel("你好", self)
        lbl1.move(15, 10)

        lbl2 = QLabel("python", self)
        lbl2.move(35,40)

        lbl3 = QLable("world", self)
        lbl3.move(55, 70)

        self.setGeometry(300, 300, 320, 120)
        self.setWindowTitle("绝对布局")
if __name__ == '__main__':  
    app = QApplication(sys.argv)
    demo = Example()
    demo.show()
    sys.exet(app.exec_())

2，PyQt5的线性布局之水平布局

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QPushButton
from PyQt5.QtCore import Qt
class WInform(QWidget):
    def __init__(self, parent=None):
        super(Windform, self).__init__(parent)

        hlayout = QHBoxLayout()
        hlayout.addWidget(QPushButton(str(1)))
        hlayout.addWidget(QPushButton(str(2)))
        hlayout.addWidget(QPushButton(str(3)))
        hlayout.addWidget(QpushButton(str(4)))
        hlayout.addWidget(QPushButton(str(5)))
        # 设置控件的间距
        hlayout.setSpaceing(0)
        self.setLayout(hlayout)
if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Winform()
    form.show()
    sys.exit(app.exec_())

3，PyQt5的线性布局之水平布局(二)

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QPushButton
from PyQt5.QtCore import Qt
class Winform(QWidget):
    def __init__(self, parent=None):
        super(Winform,self).__init__(parent)
        self.setWindowTitle("水平布局管理")
        self.resize(800,200)

        hlayout = QHbobLayout()
        #按钮水平居左，垂直居上
        hlayout.addWidget(QPushButton(str(1)),0, Qt.AlignLeft|Qt.AlignTop)
        hlayout.addWidget(QPushButton(str(2)),0, Qt.AlignLeft|Qt.AlignTop)
        hlayout.addWidget(QPushButton(str(3),5))#这里5表示的是权重
        #水平居左，垂直居下
        hlayout.addWidget(QPushButton(str(4)),0,Qt.AlignLeft|Qt.AlignBottom)
        hlayout.addWidget(QpushButton(str(5)),0, Qt.ALignLeft|Qt.AlignBottom)
        self.setLayout(hlayout)
if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Winform()
    form.show()
    sys.exit(app.exec_())

4，PyQt5的线性布局之垂直布局

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QFormLayout, QLineEdit, QLabel
class Winform(QWidget):
    def __init__(self, parent=None):
        super(Winform, self).__init__(parent)
        self.setWindowTitle("垂直布局")
        self.resize(400, 100)

        formLayout = QFormLayout()
        lab1 = QLable("标签1")
        lineEdit1 = QLineEdit()
        lab2 = QLable("标签2")
        lineEdit2 = QLineEdit()
        lab3 = QLable("标签3")
        lineEdit3 = QLineEdit()
        #向布局中添加这几个控件
        formLayout.addRow(labl1, lineEdit1)
        # 一行两个控件，水平摆放
        formLayout.addRow(labl2, lineEdit2)
        formLayout.addRow(lab3, lineEdit3)

        self.setLayout(fromLayout)
if  __name__ =="__main__":
    app = QApplication(sys.argv)
    form = Winform()
    form.show()
    sys.exit(app.exec_())

5，PyQt5的网格布局

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QPushButton
class Winform(QWidget):
    def __init__(self, parent=None):
        super(Winform, self).__init__(parent)
        self.initUI()

    def initUI(self):
        grid = QGridLayout()
        self.setLayout(grid)

        names = ['Cls', 'Back', '', 'Close',
                 '7', '8', '9', '/',
                 '4', '5', '6', '*',
                 '1', '2', '3', '-',
                 '0', '.', '=', '+']
        #使用生成器生成具体位置 5 列 4行
        positions = [(i,j) for i in range(5) for j in range(4)]
        for position, name in zip(position, names):
            if name = "":
                continue
             button - QPushButton(name)
             #Python允许你在list或tuple前面加一个*号，把list或tuple的元素变成可变参数传进去
             grid.addwidget(button, *position)
        self.move(300, 150)
        self.setWindowTitle("网格布局管理")
if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Winform()
    form.show()
    sys.exit(app.exec_())

5，PyQt5的网格布局(二)

class Winform(QWidget):
    def __init__(self, parent=None):
        super(Winform, self).__init__(parent)
        self.initUI()

    def initUI(self):
        titleLable = QLable("标题")
        authorLabel = QLabel('提交人')
        contentLabel = QLabel('申告内容')

        titleEdit = QLineEdit()
        authorEdit = QLineEdit()
        contentEdit = QTextEdit()
        grid = QGridLayout()
        grid.setSpacing(10)

        # 第一个参数表示控件,后面的两个参数表示的是控件所在的位置
        grid.addWidget(titleLable, 1, 0)
        grid.addWidget(titleEdit, 1, 1)

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

        grid.addWidget(contentLable, 3,0)
        # 最后两个参数表示的是 所占的行和所占的列，开发者自己去体会吧
        grid.addWidget(gcontentEdit,3, 1, 5,1)
        self.setLayout(grid)
        self.setGeometry(300, 300, 350, 300)
        self.setWindowTitle("申请")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Winform()
    form.show()
    sys.exit(app.exec_())

不要复制,手动敲的，要理解其中的思想就行
