is the *ui Creator specific? Can it be avoided?

Hi, as said in other thread I am completely new to Qt and UI programming as well.

I've seen some examples and mostly the widgets are put directly in the window class inherited from QMainWindow.
e.g.: window.lineEdit ...

I played around with the creator and it seems like it uses a additional *ui which points to ui_window and accessing those basic widgets is done by window.ui->lineEdit.

Is this *ui specific to applications created with the Creator? Is this some recent concept change? Can the Creator add the widgets directly in the window?

You can decide which of the three standard approaches Creator takes when autogenerating widget implementation in Designer group of Creator's settings.

The use of ui member pointer can be avoided,
but it's the most recommended way to "integrate" the auto-generated (by uic) class into your code, by that i mean:
1) it's easier to understand then multiple inheritance
2) it needs a few lines of code to write for keeping the pointer a private member (separate the UI and the code) and this means that you ensure that the UI can be changed without changing the code using it.
