QT Design 의 ui 파일을 py으로 불러오기

(버튼을 눌렀을 때 라벨의 텍스트 변경)

1. Designer에서 작성했던 버튼과 라벨의 변수명이 같아야한다.

실행시키면 윈도우창이 그대로 가져와진다.

숫자 증가시키기

<main02.py>

import sys
from PyQt5.QtWidgets import *
from PyQt5 import uic
from numpy import integer

#.ui 파일 이름이 main02.ui 일때
form_class = uic.loadUiType("main02.ui")[0]


class MyWindow(QMainWindow, form_class):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.pb.clicked.connect(self.myclick)
        
    def myclick(self):
        a = self.le.text()
        aa = int(a)
        aa += 1
        self.le.setText(str(aa))
##내용 추가
if __name__ == "__main__":
    app = QApplication(sys.argv)
    myWindow = MyWindow()
    myWindow.show()
    app.exec_()

pyqt에서는 getText()가 아니라 text()를 써줘야지 텍스트가 가져와진다.

__init__ : 생성자 , 보통 이벤트는 생성자에 많이 걸어준다

self.le_Mine.returnPressed.connect(self.myclick) : 내가 설정해준 le_Mine에서 엔터를 눌렀을 때 가위바위보 게임이 계속 진행되게 이벤트를 주는 것!
