Table of contents

1. Run interface framework

2. Basic controls

Goal 1: Add button

Goal 2: Added text:

Goal 3: Set the location


1. Run interface framework

import sys

from PyQt5.QtWidgets import QApplication,QWidget



if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()

    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 展示窗口
    w.show()

    # 程序进入循环等待
    app.exec_()



2. Basic controls

Goal 1: Add button

Required module: QPushButton

 # 按钮
    btn = QPushButton('按钮')
    # 将按钮放置在窗口中
    btn.setParent(w)

code:

import sys
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton

if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()
    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 按钮
    btn = QPushButton('按钮')
    # 将按钮放置在窗口中
    btn.setParent(w)

    # 展示窗口
    w.show()
    # 程序进入循环等待
    app.exec_()


Method Two:

    # 按钮(并将按钮放置在窗口w中)
    btn = QPushButton('按钮',w)

code:

import sys
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton

if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()
    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 按钮(并将按钮放置在窗口w中)
    btn = QPushButton('按钮',w)

    # 展示窗口
    w.show()
    # 程序进入循环等待
    app.exec_()


Goal 2: Added text:

Module required: QLabel

# 文本(并将文本放置在窗口w中)
    label = QPushButton('账号:', w)

code:

import sys
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton, QLabel

if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()
    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 按钮(并将按钮放置在窗口w中)
    btn = QPushButton('按钮',w)

    # 文本(并将文本放置在窗口w中)
    label = QLabel('账号:', w)

    # 展示窗口
    w.show()
    # 程序进入循环等待
    app.exec_()

As you can see from the illustration, the components are stacked together (then you need to set his position)


Goal 3: Set the location

label.setGeometry(60,60,60,30)

code:

import sys
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton, QLabel

if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()
    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 按钮(并将按钮放置在窗口w中)
    btn = QPushButton('按钮',w)

    # 文本(并将文本放置在窗口w中)
    label = QLabel('账号:', w)
    # 设置坐标+大小(x,y,w,h)
    label.setGeometry(60,60,60,30)

    # 展示窗口
    w.show()
    # 程序进入循环等待
    app.exec_()

The final beautified code

import sys
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton, QLabel

if __name__ == '__main__':
    # 接收参数(仅有一个)
    app = QApplication(sys.argv)

    # 创建一个窗口
    w = QWidget()
    # 窗口标题
    w.setWindowTitle("pyqt5程序")

    # 按钮(并将按钮放置在窗口w中)
    btn = QPushButton('确认',w)
    # 设置坐标+大小(x,y,w,h)
    btn.setGeometry(300, 50, 60, 30)

    # 文本(并将文本放置在窗口w中)
    label = QLabel('账号:', w)
    # 设置坐标+大小(x,y,w,h)
    label.setGeometry(50,50,60,30)

    # 展示窗口
    w.show()
    # 程序进入循环等待
    app.exec_()
