Question

In general, is the order in which I add my widgets into each other, the same order I access them back?

Example:

If I have a bunch of QPushButton in a QHBoxLayout, and this layout in a Window::ui,
can I access those button by simply ui->button_name? or Do I must do ui->layout->itemAt(idx)?

EDIT: My question aims to find an easy way to access elements that are deep into the hierarchy, like a label in a frame, inside a layout, inside a frame, inside the window etc…

PS: Also, I would really appreciate any documentations about good practices of GUI architecture!

Answer 1

Use ui->object_name you don;t need to worry about the layout!
It’s possible to redesign the layout, eg. for different platforms, without changing any of the C++ code.

There are a couple of good books on Qt and the sample code is very good.
