Use QScrollBar and QLayout to display product catalog?

[Kevin Hoang]

I have 15000 products in database; my program will connect to this database and display a list of products. Each product is a Tool Button. Program layout is fluid layout, so I use QGridLayout to make fluid layout in this case.

Somebody help me a way to make a product list with scroll bar for above case?

Thanks!

Why do you want to have 15000 toolbuttons?
Isn't there a better way to do this? Like a listview or treeview?
You can add buttons to views though.

Do you mean I can use a Tree View, and change Tree Item to button? What are methods I have to override? How to handle when use click on item to see product details?

Well, QGridLayout != fluid layout! Where is your problem after all? Use QSrollArea if you want srollbars, but as tbscope said: 15000 tool buttons is ... Leonidas would say: "This is madness!" :D
Better use - also as suggested - QListView with a proper model and delegate.

Thank you...

Can you help me what model is support for this case? I try to use setIndexWidget method, but I don't know how does it works.

If you have a database in the background holding your data, I would go for a QSqlTableModel.

:) I have a product table with struct like this:

id
langid
catid
fullname
shortname
image
...
description

So I want to display each product (each record) as a card on a category widget . Like this
_____________________________
|
|
| Product image
|
|
|____________________________
|
| Short name (Full Name)
|____________________________

With QSqlTableModel, I seen it not help me do like this.

Ehm, I will not code it for you. Have a look at the model view classes in the documentation. Also read about delegates in that content. Qt does much out of the box, but some things you must do yourself!

[Kevin Hoang]

I do not ask you code for me. I just want to ask a fast way for my case.

[tbscope]

When you want to do complex specific things, there's no fast way.

Check out this example. It will explain almost everything you need:
