I'm trying to practise by making a Pokedex. I'm trying to dynamically create a list of buttons inside of an OVBoxLayout based on the response from an API call. The list of buttons is generated correctly however, none of the buttons work, code below:
from PySide2.QtWidgets import *
from PySide2.QtCore import *
from PySide2.QtGui import *
from app.pokeapi_client import PokeApiClient
class MainWindow(QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setup_styles()
self.pokemon_list_data = PokeApiClient().get_pokemon_list(limit=9)
self.setWindowTitle("Pokemon")
self.resize(1000, 800)
# create main layout
main_layout = QHBoxLayout()
# build list layout and populate with labels
self.pokemon_list_layout = QVBoxLayout()
self.populate_pokemon_list_layout()
# add list layout to main layout
main_layout.addLayout(self.pokemon_list_layout, 1)
self.setLayout(main_layout)
def populate_pokemon_list_layout(self):
for pokemon in self.pokemon_list_data['results']:
button = QPushButton(pokemon['name'])
button.clicked.connect(self.print_this)
self.pokemon_list_layout.addWidget(button)
def print_this(self):
print("hello world!")
def setup_styles(self):
self.setStyleSheet("""
QWidget {
background: red;
}
QPushButton {
color: white;
background: blue;
border: 1px solid white;
}
""")
The button.clicked.connect() doesn't appear to be assigning the function to each button, anyone know why this might be happening?
Here is a MRE with your code :
from PySide2 import QtWidgets
from PySide2 import QtCore
from PySide2 import QtGui
DATA = {'results':[{'name':'pikka'}, {'name': 'dracofeu'}, {'name': 'mewtwo'}]}
class MainWindow(QtWidgets.QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.pokemon_list_data = DATA #Emulation data
self.setWindowTitle("Pokemon")
# self.resize(1000, 800)
# create main layout
main_layout = QtWidgets.QHBoxLayout()
# build list layout and populate with labels
self.pokemon_list_layout = QtWidgets.QVBoxLayout()
self.populate_pokemon_list_layout()
# add list layout to main layout
main_layout.addLayout(self.pokemon_list_layout, 1)
self.setLayout(main_layout)
def populate_pokemon_list_layout(self):
for pokemon in self.pokemon_list_data['results']:
button = QtWidgets.QPushButton(pokemon['name'])
button.clicked.connect(self.print_this)
self.pokemon_list_layout.addWidget(button)
def print_this(self):
sender = self.sender()
print(sender.text())
app = QtWidgets.QApplication([])
test = MainWindow()
test.show()
app.exec_()
Here is the result : As you can see I didn't change anything (except imports and the sender in the print_this method) but it works. I think you have a problem somewhere in your code.
