Multi-page application and QStackedWidget

[jamie721]

I think the object orientated process would help you alot. go into google and search about object oriantated programming. This will help you understand how you can break stuff up into smaller chunks and also re use code so that you dont have repetative code in your application.

I know object-oriented programming, probably I don't know so well, but I followed your advise and I searched in google but I didn't find nothing new.
This multi-page application is not like a wizard-style sequence.
At the moment I have two ideas/solution:

Idea/solution n°1:
-) One Form "MyForm" created using Designer where I put the QStackedWidget and create the GUI (so put in each pages the custom widget using Designer)
-) One class "MainWindow" inherit from QMainWindow and from Ui::MyForm that deal the interaction between the QStackedWidget pages
-) Thirty or more classes that deal the content of each page

In this way I have only improved the legibility

Idea/solution n°2:
-)One Form "MyForm" created using Designer where I put the QStackedWidget
-)One class "MainWindow" inherit from QMainWindow and from Ui::MyForm that deal the interaction between the QStackedWidget pages
-)Thirty Form "PageXXXForm"one for each Page
-)Thirty or more classes inherit from QWidget and Ui::PageXXXForm that deal the content of each page

At the beginning the class "MainWindow" could create all the PageXXX object or only the 5-6 normally used and then create the other when necessary.
But in this way I create a lot of classes one for each page.

Probably solution n°2 is a good solution, but it is possible to do better?

If someone has an idea or tell me where I made a mistake please tell me

Thanks

Frankly, 30 separate pages - each crammed with customized widgets - sounds hideously complex. I doubt I would bother trying to learn such a complicated interface unless there were some exceptionally good reason to do so.

What, exactly, is this program supposed to do?

[Mek82]

I think that is the structure to create a lot of different GUI application.
The start screen is full of custom push button (like the Iphone) pushing on them you could go to a specific page where you could go to another page/pages pushing other push button.
So it is easy to have 30 pages.
Obviously only 5-6 pages are often used and the other pages less.
Every page has a lot of custom widget to create a personalized GUI application.
I think that is important to understand the best way to do.

I know object-oriented programming.

Good, then you will understand that the multiple inheritance approach you have chosen:

-)One Form "MyForm" created using Designer where I put the QStackedWidget
-)One class "MainWindow" inherit from QMainWindow and from Ui::MyForm that deal the interaction between the QStackedWidget pages
-)Thirty Form "PageXXXForm"one for each Page
-)Thirty or more classes inherit from QWidget and Ui::PageXXXForm that deal the content of each page

is only one of several ways to incorporate Designer generated code into your application. You could equally chose the single inheritance approach and save some files. See "Using a Designer UI File in Your Application" in the Designer manual for more information. If you are using Qt Creator then you have options related to the method to use when creating a new UI class.
