Can you look at Assistant for "Creating Custom Widgets for Designer". This will surely help you. I know you don't want to code.

Designer creates the *.h file called ui_<yourname>.h file. You can take this file and split the file as .h and .cpp.

Now you can tweak the process of doing the same.

I generated the header file from Qt Designer but it has this #include "qframe.h" that Creator is unable to find. WHat to do about this?

Are able to create the project with designer form and run your program ? If yes, you should find out the path in which this file exist and give the appropriate include dir path for the project.

I used Qt 5.2.x and I designed form with QFrame etc. I did not see the any qframe.h included. May be it is specific to your design.

What I want is a custom widget with some lables, line edits and few other components in it. This component will be used as a UI element in another Qt project. So I create a Frame in designer and included all components I want in this widget. Now I want this Frame with all the widgets it contain to be available as a separate file so that I can simply promote a Widget to this frame (containing other components) in the main project.

Shouldn't I be creating a frame in designer is this task to be done in some other way?

No it is right. QFrame is derived from QWidget. It should be fine. I tried to create very similar UI using the designer. My *.h files did not had any qfame.h file. Can you check with small example first ? Which version of Qt you are using ?

I'm using Qt 5.3.1

I tried creating a small sample in this way-

Start Designer -> New -> Widgets -> QFrame -> create
Added a few components like sliders etc.
Form -> view code -> save the header file (ui_sadsad.h)
Created a new Qt Widgets project in Creator and added the header file obtained from Designer to this project.
In the auto-created ui file, added a Widget and promoted it to Ui_Sadsad.
Built and got error in ui_mainwondow.h-

@/********************************************************************************

        MainWindow->setObjectName(QStringLiteral("MainWindow"));
    MainWindow->resize(400, 300);
    centralWidget = new QWidget(MainWindow);
    centralWidget->setObjectName(QStringLiteral("centralWidget"));
    widget = new Ui_Frame(centralWidget);
    widget->setObjectName(QStringLiteral("widget"));
    widget->setGeometry(QRect(60, 50, 120, 80));

    MainWindow->addToolBar(Qt::TopToolBarArea, mainToolBar);
    statusBar = new QStatusBar(MainWindow);
    statusBar->setObjectName(QStringLiteral("statusBar"));
    MainWindow->setStatusBar(statusBar);

    retranslateUi(MainWindow);

    QMetaObject::connectSlotsByName(MainWindow);
} // setupUi

void retranslateUi(QMainWindow *MainWindow)
{
    MainWindow->setWindowTitle(QApplication::translate("MainWindow", "MainWindow", 0));
} // retranslateUi

};

namespace Ui {
class MainWindow: public Ui_MainWindow {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_MAINWINDOW_H

I think stem 5 onwards I'm doinf it wrong.

Anyways, can you point me to the correct steps?

oh!!!. ui_frame.h file generated file. Your designer class name frame. Hence it is generating ui_frame.h file. You can remove this and do what split you want to for .h and .cpp files.

But then you have error in every line that refers to Ui_Frame like line 30 and 42. It's really irritating me.
