With Qt Designer you can add items to a combo box (double-click on the combobox to show up the editor). But if your folder list will vary, you'll have to do it by code.
I think you have to do it in code. You can fill the combo box in the designer as soon as you are using static values. It is something you are doing dynamically like obtaining the bookmarks folders then you have to do it in your business logic code.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
