Generate .h and .cpp from .ui file

Question

Suppose I have the file about.ui. How can I make the "about.h" and the "about.cpp" from my .ui file? I have to create a .moc file too? How can I compile this after the creaton to see if all ocurred correctly?

Answer 1

You don't.
The about.ui generates a ui_about.h which you include in your own about.h

You then create you own class deriving from this class

class about :   public QDialog, public Ui::about
{
    Q_OBJECT;
....
}

Answer 2

Short answer:

In QtCreator there are two ways of create a form from windows assistant: - Qt Designer Form Class - QtDesigner Form

you must create a new "Qt Designer Form Class" instead of "Qt Designer Form", because you choose "Qt Designer Form" qt creator doesn't create the .h and .cpp from .ui file:

Long Answer:

When you create "QTCreator Form" only create .ui file this is useful if you already have an existing class for the UI business logic and you want rebuilt user interface but keep business logic, you can call buttom or components with same name and interchange ui.

Answer 3

If automatic generation does not work (like in my case) you can use uic to generate the header file manually. uic file.ui > file.h
