Adding lib files and their paths in .pro file [Closed]
-
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....[edit: code highlighted with @ tags / Denis Kormalev]

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.

[quote author="imrrk" date="1303796480"]thanks leon ,but i want to know how to create a lib file of my project[/quote]
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/

[/quote]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.

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

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.

hey gerolf,I am sorry but if you r with me,we will go from first,
now I have created freshly two projects and named as test1 and test2.which contains nothing.now tell me what is my first step and whether i have to create lib file?I will go as per your instructions,
regards

hey andre i have created a .pri file as per your instructions,my test11.pri looks like below
@SOURCES *= dialog.cpp
HEADERS *= dialog.h
FORMS *= dialog.ui@
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 -
- ../common/ is the directory where all my .pri files are. You need this to have qmake find your source files.
- ../common/src is the directory where all the source and header files for my components are. You need that to be able to #include them.
- the include statement actually pulls in the contents of the .pri file into the .pro file.
So, what you put where, depends on where your components are in your file structure. In my case, I have something like this as my root structure:
@
common
common/src
common/ui
common/resources
project1
project1/src
project2
project2/src
project2/ui
project2/resources
@
etc. The .pri files are in the directory common, while the .pro files are in the different project directories (project1 and project2). -
ok andre i got your point and i have included in my main project i.e test2.pro file the below lines
@INCLUDEPATH += ../test11
include(../test11.pri)@and in my main project ie test2,i have dialog1.cpp and i have include this code
@#include "dialog1.h"
#include "ui_dialog1.h"#include "dialog.h"//this is from my previous project test11
Dialog1::Dialog1(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog1)
{
ui->setupUi(this);
}Dialog1::~Dialog1()
{
delete ui;
}void Dialog1::on_pushButton_clicked()
{
Dialog a(this);
a.show();
a.exec();
}@
now only one error i am getting
bq. :: error: collect2: ld returned 1 exit statuswhether i am on the right track?
