Button to +1 in text box everytime it's clicked

[martyloo]

Hello I have the following code that I want it to start counting from 0 adding 1 every time "pushbutton" is pressed and the value to be shown in "textBrowser", is this possible as I am having some trouble?:

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(656, 383)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(230, 50, 51, 41))
        self.pushButton.setObjectName("pushButton")

self.textBrowser = QtWidgets.QTextBrowser(self.centralwidget)
        self.textBrowser.setGeometry(QtCore.QRect(80, 180, 61, 41))
        self.textBrowser.setObjectName("textBrowser")

You must create a window and connect the button to a function.

from PyQt5 import QtWidgets
 
class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent = None):
        super(MainWindow, self).__init__(parent)
        self.setup_ui()
    
    def setup_ui(self):
        toolbar = self.addToolBar("Tools")
        self.count_button = QtWidgets.QPushButton("+")
        self.count_button.clicked.connect(self.on_btn_clicked)
        toolbar.addWidget(self.count_button)
 
        self.text_browser = QtWidgets.QTextBrowser()      
        self.text_browser.setText("0")
        self.setCentralWidget(self.text_browser)
        
        self.counter = 1
                
        self.resize(656, 383)
        
    def on_btn_clicked(self):
        self.text_browser.setText(f"{self.counter}")
        self.counter += 1

        
if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    win = MainWindow()
    win.setWindowTitle("MainWindow")
    win.show()
    sys.exit(app.exec_())

or use a Spinbox

from PyQt5 import QtWidgets
 
class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent = None):
        super(MainWindow, self).__init__(parent)
        self.setup_ui()
    
    def setup_ui(self):
        toolbar = self.addToolBar("Tools")
        
        self.spin_box = QtWidgets.QSpinBox()
        self.spin_box.valueChanged.connect(self.on_spin_box)
        toolbar.addWidget(self.spin_box)
 
        self.text_browser = QtWidgets.QTextBrowser()      
        self.text_browser.setText("0")
        self.setCentralWidget(self.text_browser)
                
        self.resize(656, 383)
        
    def on_spin_box(self):
        self.text_browser.setText(f"{self.spin_box.value()}")

        
if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    win = MainWindow()
    win.setWindowTitle("MainWindow")
    win.show()
    sys.exit(app.exec_())
