将按下的按钮的名称存储在变量中

  • 772

我想在按下按钮后跟踪按下了哪个按钮。
将此值保存在变量中，并将变量的值输出到方法click()。

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import *

class Ui_Window1(object):
    def setupUi(self, Window1):
        Window1.setObjectName('Window1')
        Window1.resize(450, 800)

    您的任务应如下所示：

    from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.Qt import *


class MainWindow(QtWidgets.QMainWindow):
    HEX1, HEX2, HEX3 = '#4c5359', '#363940', '#ffffff'
    d, r = 2, 30
    
    def __init__(self):
        super().__init__()

        self.centralWidget = QtWidgets.QWidget()
        self.centralWidget.setObjectName("centralWidget")
        self.setCentralWidget(self.centralWidget)        
        
        self.label = QtWidgets.QLabel(alignment=Qt.AlignCenter)
        self.label.setWordWrap(True)
        
        self.layout = QVBoxLayout(self.centralWidget)
        self.layout.setSpacing(7)
        self.layout.addWidget(self.label, 1)
        
        for i in range(4):
            button = QtWidgets.QPushButton()
            button.setMinimumHeight(60)
            button.setStyleSheet(f'''
                QPushButton {{
                    background-color: {self.HEX1};
                    border: {self.d}px solid {self.HEX2};
                    border-radius: {self.r};
                    color: {self.HEX3};
                    width: 390;
                    height: 60;
                }}
            ''')
            button.setText(f'button {i+1}')
            button.clicked.connect(lambda ch, btn=button: self.clicked_button(btn))
            self.layout.addWidget(button)

        self.layout.addStretch(1)
        
    def clicked_button(self, button):
        text_button = button.text()
        #print(f'{text_button}')
        self.label.setText(f'Последняя нажатая кнопка: `{text_button}`')
        
      

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    app.setFont(QtGui.QFont("Bahnschrift SemiBold", 12, QtGui.QFont.Bold))
    app.setStyleSheet('''
        #centralWidget {
            background-image: url(first.jpg);
        }
        QLabel {
            font-size: 18pt;
            color: white;
        }
    ''')
    w = MainWindow()
    w.resize(450, 600)
    w.show()
    sys.exit(app.exec_())
