Add custom widget to a mainwindow

[aguleo]

Supose i have a QWidget ...

#-------------------------------------------------
#
# Project created by QtCreator 2013-05-06T14:58:35
#
#-------------------------------------------------
 
QT       += core gui
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
TARGET = widget
TEMPLATE = app
 
 
SOURCES += main.cpp\
        widget.cpp
 
HEADERS  += widget.h
 
FORMS    += widget.ui

#-------------------------------------------------
#
# Project created by QtCreator 2013-05-06T14:58:35
#
#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = widget
TEMPLATE = app


SOURCES += main.cpp\
        widget.cpp

HEADERS  += widget.h

FORMS    += widget.ui

To copy to clipboard, switch view to plain text mode 

... and a QMainWindow ...

TARGET = mainwindow
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

Both were created separately.

Now i want to use the Widget as the centralWidget of the mainwindow.
If i copy the widget folder to the mainwindow folder, what is the next step to integrate them?

No, You have two project files. Why ? Just create one project file integrating all cpp, h and ui files.The rest is a simple C++.

I was thinking of renaming the .pro to .pri, in the widget, and then make the necessary changings.
After that, i should try to promote the widget and set it a central widget.
The idea was to keep them separated as mush as possible!

Add the windget files to the mainwindow project

Add the windget files to the mainwindow project

But this can be done via a pri file...right?

Added after 1 4 minutes:

It works by doing:
1 - placing the widget folder inside the mainwindows folder;
2 - adding include(widget/widget.pri) to mainwindow.pro
3 - renamming the widget.pro to widget.pri and changing it's content to:

SOURCES += widget/widget.cpp
 
HEADERS  += widget/widget.h
 
FORMS    += widget/widget.ui

SOURCES += widget/widget.cpp

HEADERS  += widget/widget.h

FORMS    += widget/widget.ui

To copy to clipboard, switch view to plain text mode 

It gives me a good organization in QtCreator but, after making all this changes, it might be better to simply add everything to the mainwindow.pro
