『PyQt5-Qt Designer篇』｜ 08 Qt Designer中容器布局和绝对布局的使用

(08 Qt Designer中容器布局和绝对布局的使用)

1 容器布局

1.1 设计容器布局

• 先拖入一个容器Frame容器，然后拖入几个控件：
• 把拖入的控件拖入容器中：
• 选中容器，右键-布局-栅格布局：

1.2 保存文件并执行

• 保存为test007_ConFra.ui，并生成test007_ConFra.py：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'test007_ConFra.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.


from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(794, 584)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.frame = QtWidgets.QFrame(self.centralwidget)
        self.frame.setGeometry(QtCore.QRect(90, 100, 389, 74))
        self.frame.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame.setObjectName("frame")
        self.gridLayout = QtWidgets.QGridLayout(self.frame)
        self.gridLayout.setObjectName("gridLayout")
        self.pushButton = QtWidgets.QPushButton(self.frame)
        self.pushButton.setObjectName("pushButton")
        self.gridLayout.addWidget(self.pushButton, 0, 0, 1, 1)
        self.pushButton_2 = QtWidgets.QPushButton(self.frame)
        self.pushButton_2.setObjectName("pushButton_2")
        self.gridLayout.addWidget(self.pushButton_2, 0, 1, 1, 1)
        self.lineEdit = QtWidgets.QLineEdit(self.frame)
        self.lineEdit.setObjectName("lineEdit")
        self.gridLayout.addWidget(self.lineEdit, 0, 2, 1, 1)
        self.lineEdit_2 = QtWidgets.QLineEdit(self.frame)
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.gridLayout.addWidget(self.lineEdit_2, 1, 0, 1, 2)
        self.lineEdit_3 = QtWidgets.QLineEdit(self.frame)
        self.lineEdit_3.setObjectName("lineEdit_3")
        self.gridLayout.addWidget(self.lineEdit_3, 1, 2, 1, 1)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 794, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "PushButton"))
        self.pushButton_2.setText(_translate("MainWindow", "PushButton"))

• 创建main.py，并执行：

import sys
from test_case.test007_ConFra import Ui_MainWindow
from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow


if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(window)
    window.show()

    sys.exit(app.exec_())

2 绝对布局

2.1 设计绝对布局

• 直接把控件放到窗口或者容器中，默认就是绝对布局；
• 拖入如下的控件：

2.2 保存文件并执行

• 保存为test008_AbsLay.ui，生成test008_AbsLay.py：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'test008_AbsLay.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.
