Get ID of dynamically created button when clicked - python-3.x

Question

I have a program that dynamically creates tabs with buttons on them, when the user clicks button, I want it to give me the button_id (number that corresponds to the tab index).
I understand that you can do something like tabwidget.currentIndex() to get index of tab being used, but I don't want that as I will eventually have a method that iterates through the number of tabs and access each button without selecting the tabs as shown below.
for i in range(1,self.tabWidget.count()):
self.tabWidget.widget(i).stagematch.click()
For example:
If user clicks 'Clear Text' button on 'Tab 2' then I want it to give me the number 2 back.
How can I accomplish this without using the currentIndex() method for the tabs
Test code:
import sys
from PyQt5 import QtCore, QtWidgets
class TabPage(QtWidgets.QWidget):
def __init__(self, parent=None):
super().__init__(parent)
group = QtWidgets.QGroupBox('Monty Python')
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(group)
grid = QtWidgets.QGridLayout(group)
testbutton = QtWidgets.QPushButton('Clear Text')
grid.addWidget(testbutton, 2, 2)
testbutton.clicked.connect(self.tab_match)
#testbutton.clicked.connect(self.button_id)
def button_id(self):
sender = self.sender()
print(sender.text()) # Gives text of button, i'd like a number that corresponds to the tab# that called it
def tab_match(self,button_id):
#Do something with button ID here
pass
class Window(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.tabs = QtWidgets.QTabWidget()
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
button = QtWidgets.QToolButton()
button.setToolTip('Add New Tab')
button.clicked.connect(self.addNewTab)
button.setIcon(self.style().standardIcon(
QtWidgets.QStyle.SP_DialogYesButton))
self.tabs.setCornerWidget(button, QtCore.Qt.TopRightCorner)
self.addNewTab()
def addNewTab(self):
text = 'Tab %d' % (self.tabs.count() + 1)
self.tabs.addTab(TabPage(self.tabs), text)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = Window()
window.setGeometry(600, 100, 300, 200)
window.show()
sys.exit(app.exec_())

Try it:
import sys
from PyQt5 import QtCore, QtWidgets
class TabPage(QtWidgets.QWidget):
def __init__(self, parent=None):
super().__init__(parent)
self.parent = parent # +
self.button_id = 0 # +
group = QtWidgets.QGroupBox('Monty Python')
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(group)
grid = QtWidgets.QGridLayout(group)
testbutton = QtWidgets.QPushButton('Clear Text')
grid.addWidget(testbutton, 2, 2)
testbutton.clicked.connect(self.tab_match)
self.parent.currentChanged.connect(self.qtabwidget_currentchanged) # +
def tab_match(self):
#Do something with button ID here
print("\ndef tab_match: button_id-> {}".format(self.button_id)) # +
#QtCore.pyqtSlot(int)
def qtabwidget_currentchanged(self, index): # +
self.button_id = index
class Window(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.tabs = QtWidgets.QTabWidget()
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
button = QtWidgets.QToolButton()
button.setToolTip('Add New Tab')
button.clicked.connect(self.addNewTab)
button.setIcon(self.style().standardIcon(
QtWidgets.QStyle.SP_DialogYesButton))
self.tabs.setCornerWidget(button, QtCore.Qt.TopRightCorner)
self.button_id = 0
self.addNewTab()
def addNewTab(self):
text = 'Tab %d' % (self.tabs.count() + 1)
self.tabs.addTab(TabPage(self.tabs), text)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = Window()
window.setGeometry(600, 100, 300, 200)
window.show()
sys.exit(app.exec_())
