I have two lists, one list is for all of the data frames the user added (listOfOriginalDataFrames), and another one is a list of all the data frames the user wishes to display (listOfDisplayedDataFrames). I’m using a QCheckBox, and I’m trying to make my code so that when the user checks the box, that selected data frame will be appended to the listOfDisplayedDataFrames, and when its unchecked, it will be removed. The checkboxes .setChecked are based on if the data frame is in the listOfDisplayedDataFrames.
