[solved]how can i include a class in a dialog?
in my program what shoudl i do if i want to include an object class(User class in here) that i myself define it ,
and then use that class in one of functions (on_cmdOk_clicked() )of my dialog(Signup in here)?
i try these code:
Users users; users.insert(UserName,PassWord,FirstName,LastName,int id=-1);
but i recieve below error:
..\signup.cpp:3:21: error: ../User.h: No such file or directory
..\signup.cpp: In member function 'void Signup::on_cmdOk_clicked()':
..\signup.cpp:36: error: 'Users' was not declared in this scope
..\signup.cpp:36: error: expected ';' before 'users'
..\signup.cpp:37: error: 'users' was not declared in this scope
..\signup.cpp:37: error: expected primary-expression before 'int'
and this is my .pro file:
TARGET = NoteBook
TEMPLATE = app
SOURCES += dialog.cpp
HEADERS += dialog.h
FORMS += dialog.ui
INCLUDEPATH += ../@
if someone knows the answer please help me.
It looks like your include path is wrong. The compiler complains that the include file "../Users.h" is not found.

This include section would look a bit more logical based on the information of your .pro file.
yeah .you're right.
it works now properly.
thank you to reply and help me.
in my User class there is a file that save information of users.
if i want to insert a new user in (on_cmdOk_clicked()) function,can i get an object from User class in main.cpp and use that object and it's functions (like insert) in the above function of Signup.cpp(Signup is a dialog in my program)?
because if i want to get an object of User class in that function (on_cmdOk_clicked()) ,whenever that ok button be pushed ,an object of User class and then a file iwill be create and it's not true.
can you help me in this topic too?
I just want to make you aware of on option to store such information user names and related information into a file. "QSettings ":http://doc.qt.nokia.com/4.7/qsettings.html Typically QSettins facilitates that quite nicely for different applications and platforms. On windows you have the option to store in ini-files and also for linux the data are more easily maintained compared to hand-knitted files. You may use the file structure behind the scenes and open it from any place in your program. Maybe that would be of help.
I cannot answer your quite detailed question above. main.cpp is just a name of a file which presumably holds most or all information of your code. It all depends on what you are trying to achieve and how your program is setup. I guess it is somehow possible, but there is no way to provide details without knowing more. Anyhow, I think it would be good if you have a look to the possibilities of QSettings.
