Add Custom Widget to listWidget on pyqt5

Question

I used Qt Designer to make two .ui files, one is the Main Window of my application, and the second is a custom widget I made. My idea was to fill a listWidget on my Main application with this custom Widget to display data.

I made this code, which compiles without problem but it does not show the customWidget on the List when it runs

import sys 
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget,QVBoxLayout,QDialog
from PyQt5 import QtCore, QtGui, QtWidgets
from mainwindowReclamo import Ui_MainWindow
from widgetReclamos import Ui_Form
#Custom Widget*
class WidgetReclamo(QWidget, Ui_Form):
 """docstring for ClassName"""
 def __init__(self,*args,**kwargs):
 QWidget.__init__(self,*args,**kwargs)
 self.setupUi(self)
 print("I am Alive")
 
#My Main Program*
class ProgramaReclamos(QMainWindow, Ui_MainWindow): 
 def __init__(self,*args,**kwargs):
 QMainWindow.__init__(self,*args,**kwargs)
 self.setupUi(self)
 #I create an Item*
 Item = QtWidgets.QListWidgetItem(self.listWidget)
 #I create a custom widget*
 Item_Widget = WidgetReclamo()
 #I set the Size from the Item to the same of the widget*
 Item.setSizeHint(Item_Widget.sizeHint())
 #I add it to the list*
 self.listWidget.addItem(Item)
 self.listWidget.setItemWidget(Item, Item_Widget)
 
if __name__ == '__main__':
 app = QApplication(sys.argv)
 prog = ProgramaReclamos()
 prog.show()
 sys.exit(app.exec_())

I saw some questions online which their answer were for PyQt4 and they said something about using a Layout for the Widget, but I don ́t understand if I have to make one because the widget was made in the .ui file

• eyllanesc: Execute this: print(Item_Widget.sizeHint())
• eyllanesc: Change Item.setSizeHint(Item_Widget.sizeHint()) to Item.setSizeHint(Item_Widget.size())
• Nahuel Varela: My god, it worked. Man, thank you so much! you have helped me two times in a row!

Answer 1

As EYLLANESC said on the comment:

Change Item.setSizeHint(Item_Widget.sizeHint()) to Item.setSizeHint(Item_Widget.size()) – eyllanesc

Thank you !
