"Including pro-files into pro-files":http://developer.qt.nokia.com/wiki/IncludingProFiles . Is this helpful?

imrrk

,hey i read it,but suppose i have a push button in say 4.pro and the fuction on click has been written in 3.pro so whether your link provides me the solution for this..

thanks

Normally you won't have a button in one project and its onClick in another ... they should be in one class which will be in one project.

giesbert

The only option to have classes in one project and the slots in another would be to have a class in project 1 which is exportet and then used inside the other. but members inside one project should never be used in others...

Most likely you don't need all of this.

Honestly it seems like a bad architecture to me. Why don't you split them into "several libraries and include them at your new project":http://doc.qt.nokia.com/qtcreator-snapshot/creator-project-qmake-libraries.html ?

Hi imrrk,

Unfortunately I am not Qt Creator expert and I cannot advise you. But whatever Qt Creator is doing it can be done manually but you will have to read the documentation carefully. Some useful links:
"qmake Manual":http://doc.qt.nokia.com/4.7/qmake-manual.html
"INCLUDEPATH":http://doc.qt.nokia.com/4.7/qmake-variable-reference.html#includepath
"LIBS":http://doc.qt.nokia.com/4.7/qmake-variable-reference.html#libs

LIBS and INCLUDEPATH are important keywords that you should use to point out which libraries do you want to include and what is the path to the header files.

Best regards,
Leon

hi gerolf,I will explain it in detail,now i have already created a application,and now i want to add few more dialogs at the beginning of my application,so for that i have created a diffrent project and know i want just to integrate these two projects..so please help me out..

Actually i hv one pushButton in different project file and on the click of push button it should refer to a Mainwindow which is present in another project file..i created the lib file of one project say test.pro in the below way..
@
TEMPLATE=lib
CONFIG+=dll
@
After writing this code in test.pro file and when i build it..i get two files test.a and test.dll in test-buildsimulator folder..

Now i added this path of the lib file in my test1.pro file in the following way....

@
win32:
{
LIBS += -L../test-build-simulator/debug
}
LIBS += -ltest
}
@
wether i am proceeding correctly....

Then your push button should be connected to a signal of your dialog. your dialog is exported so you can connect to it from outside the lib. The push button is not accessible from outside.

This is a normal C++ issue, hide members from being used from outside of the class.

I think you are on the right way as you have already started to rework the project. For hints regarding dynamic library you can also check "this thread":http://developer.qt.nokia.com/forums/viewthread/5204/

I am just wondering which is your target platform because here I see win32 and the thread is in Mobile and Embedded section?

hi leon ,i am working for symbian device..only and whether we should include these lines ?
and hey please help me about the pushbutton issue

imrrk

hey gerolf,i am not getting you..........

leon.anavi

Hi imrrk,

For Symbian specific things use symbian at the .pro file.

In this case it is highly recommended to a look at this article at Forum Nokia about "shared libraries on Qt for Symbian":http://wiki.forum.nokia.com/index.php/Shared_Library_DLLs_on_Qt_for_Symbian

If you are planning to develop commercial software please note the remarks about UID and Symbian Signed - you might need to sign your DLL too!

P.S.
Please try to avoid spam and combine your message in a single post or edit existing post when it is possible.

Hi imrrk,

you should design a clean dialog.

So your dialog might have custom signals-. How they are emitted does not matter to the user of the dialog, also not which widgets are placed on it. The signal can be emitted when the push butrton is pressed.

@
MyDialog::MyxDialog()
{
UI = new ...
ui->setupUI(this);

connect(ui->button, SIGNAL(clicked()), this, SIGNAL(myClickedSignal()))

}
@

This is pseudo code, not build, not tested

Note that this topic has been explained more than once already. Like in "this":http://developer.qt.nokia.com/forums/viewthread/5144/ thread. Your case is not so different, so learn from the answers that are already there first.

hi Gerolf

Actually my dialog where i have a pushbutton is in one project file and the dialog which i want to connect it through this pushbutton is in another project file and both project files are in seperated folder,i.e i have created one project file and my friend has created another project file,so i want to integrate these two diffrent projects
