QT program

[leardfazliu]

I made a chashier program and now i want to do it with qt program.
1.How can i make dynamic folders(buttons) which i can open them just if there is saved data(made a payment), and for example if there isnt a folder(button) of the year that the payment has been done to create one, if there isnt create a folder of month to create one and if there isnt created a folder of day to create and the titles of these folders should be for example for year just "2016" for month just "January" for folder day to be just "13".
