Program is for linux distributions.
I am trying to notify user when something is wrong with the item in the list when it is double clicked.
I used setStyleSheet, only to find out that it does not work on unity and cinnamon, while it works on KDE and i3.

I am not all that savvy with qbrushes or some other stuff I am googling out.
So whats the best way to solve this, so that it works everywhere? Thanks.

Heres a gif of my solution in action on i3wm.

  7. class My_Model_table(QAbstractTableModel):

  10.         self.table_data = table_data
  11.  
  12.     def rowCount(self, parent):
  13.         return len(self.table_data)
  14.  
  15.     def columnCount(self, parent):
  16.         return 1
  17.  
  18.     def data(self, index, role):
  19.         if role == Qt.DisplayRole:
  20.             value = self.table_data[index.row()]
  21.             return value
  22.         if role == Qt.TextAlignmentRole:
  23.             return Qt.AlignCenter
  24.

  26. class My_table(QTableView):
  27.     def __init__(self, parent=None):
  28.         super().__init__()
  29.         self.activated.connect(self.double_click_enter)

  46. if __name__ == '__main__':
  47.     app = QApplication(sys.argv)
  48.     data = ['1', '2', '3', '4', '5']
  49.     main_table = My_table()
  50.     main_table.setModel(My_Model_table(data))
  51.  
  52.     main_table.show()
  53.     sys.exit(app.exec_())
