Question

我有这个非常简单的GUI，但我无法按下按钮。我尝试在clicked.connect命令中使用部分和 lambda ，但没有运气。我知道我只能按下按钮一次，因为我没有循环来改变每个新输入框的位置，但我只想让它先工作。

感谢您的任何建议

for file in $(find . -name '*.mp3') ; do
   base="${file%%.mp3}"
   cp "$base.jpg" "$base-poster.jpg"
   cp "$base.jpg" "$(dirname $base)/poster.jpg"
done

试试这个：

import sys
from PyQt5.QtWidgets import (QApplication, QWidget, QPushButton, QSizePolicy,
                         QDoubleSpinBox, QLabel, QCheckBox, QMainWindow,
QGridLayout)
from PyQt5.QtCore import QCoreApplication
import matplotlib
from matplotlib.figure import Figure
import numpy as np
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar



class MainWindow(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):

        # Geometry of main window:
        self.setGeometry(200, 200, 1000, 1000)
        self.setWindowTitle('Simulation')

        #---------------------------------------
                # Button for adding blades
        blade_button = QPushButton('Add', self)
        blade_button.clicked.connect(self.add_Bladebox)
        blade_button.move(800, 600)


        #---------------------------------------

        self.show()

    # Method for input box:
    def inputBox(self, left, top, maxvalue, step, default,decimals):
        box = QDoubleSpinBox(self)
        box.move(left,top)
        box.setDecimals(decimals)
        box.setMaximum(maxvalue)
        box.setSingleStep(step)
        box.setProperty("value", default)
        box.resize(box.sizeHint())
        box.show()

    # Method for adding blade boxes
    def add_Bladebox(self):

        print('This is Ok')

        left = 900
        top = 500
        maxvalue = 3
        step = 1
        default = 0
        decimals = 1
        self.inputBox(left, top, maxvalue, step, default, decimals)


if __name__ == '__main__':

    app = QCoreApplication.instance()
    if app is None:
        app = QApplication(sys.argv)
    ex = MainWindow()
    sys.exit(app.exec_())

pyqt5 QPushButton（）（使用clicked.connect（））不起作用
