Project hierarchy with subfolders

[YoniBE]

hello!
when I create new project, I don't have subfolders such as header, source and form folders for my project files. all my files are located at one folder (project folder).
How can I change the organization of project files?

this is part of my .pro file

SOURCES += \
        album.cpp \
    pictures.cpp \
    databasemanager.cpp \
    albumdao.cpp

HEADERS += \
        album.h \
        gallery-core_global.h \ 
    pictures.h \
    databasemanager.h \
    albumdao.h

and this is screen shot of the project hierarchy:

thanks for help! :)

@YoniBE You can put your files in subdirectories and edit the pro file to reflect these changes:

SOURCES += \
        somedir/album.cpp \
    somedir/pictures.cpp \
    somedir/databasemanager.cpp \
    somedir/albumdao.cpp

HEADERS += \
        someotherdir/album.h \
        someotherdir/gallery-core_global.h \ 
    someotherdir/pictures.h \
    someotherdir/databasemanager.h \
    someotherdir/albumdao.h

to add to @jsulm

if you include files from an other directory you'll have to adjust the include statement:

#include "someotherdir/pictures.h"

or add the directory to your Includepath in your *pro file

INCLUDEPATH +=$$PWD/someotherdir

@jsulm @J-Hilk
Dosen't work..
I create new folder at the project folder named "sources", then I added to pro file

SOURCES += \
        sources/album.cpp \
    sources/pictures.cpp \
    sources/databasemanager.cpp \
    sources/albumdao.cpp

But I don't see any difference at the project hierarchy. I tried to create a new project and do the same but still I don't see any difference.
I remember that once it was automatically... like in visual studio

@YoniBE You should run qmake after editing pro file

@jsulm
still, I don't see any differences.
this is the output of the qmake

11:35:33: Running steps for project untitled...

slove it.
I changed the hierarchy view to file system view instead of project view and it worked.
Thanks!!
