        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 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.

                          hello andre,I have two different prjects and am trying to integrate these projects,such has on click of pushbutton in my one project it should open a dialog which is present in another project so that it can be solved in a modular way..

                            Imrrk,

                            did you read the posts?

                            Create a signal in the exported dialog, which is triggered by the button.

                            use this signal for your actions.

                            Anything unclear with this statement?

                              There are several ways to do this. Do you want a full-fledged library, or just use different .pro files for your components? I use the second way frequently.

                              Instead of using a .pro file, I use a .pri file. They are the same format, but a .pri file is semantically different. It does not describe a complete project, it only describes what is needed for a single component that I may use in several projects. A typical .pri file might look like this for me:

                              @
                              SOURCES *= src/fileselector.cpp
                              HEADERS *= src/fileselector.h
                              FORMS *= ui/fileSelectorUI.ui
                              @

                              Then, in the project where I want to use this component, I have this in the .pro file (along with everything else that needs to be in the .pro file to make it a complete project, of course):

                              @
                              VPATH = ../common/
                              INCLUDEPATH += ../common/src/

                              include(../common/fileselector.pri)
                              @

                              In my source, where I use this component, I then only need to do this:
                              @
                              #include "fileselector.h"
                              @

                              and I can access everything I need from the FileSelector component. I am currently using this pattern for about 30 components that I use across 10 or so applications, so I can vouch for this method working.

                              A downside to this method is that if you change something in a component, you need to re-compile all the applications that use that component. Also, each component is re-compiled for every application. If you put the component in a real library, you only need to compile it once when it changes. Also, if you have several of these different applications sharing the same components open at the same time, you can share the memory needed for them.

                                    Exactly the same way you would construct a .pro file. In your editor. It is just a text file after all.

                                      now in your above post u said to add these in my main project ie. test2.pro file..so how shall i include it according to you
