Solved How to pass command line arguments from main.cpp to mainwindow.cpp
-
Hi All,
I am passing two arguments when running my project from terminal in linux like
./project_exe <arg1> <arg2>
These two values comes in main.cpp . Now i want to pass the values of these two arguments into a function defined in mainwindow.cpp.How this can be achieved?
Kindly suggest...

Hi,
QCommandLineParser for the first part and then just call your MainWindow object function with the corresponding parameters.

Hi
what part is causing you an issue ?for only 2 arguments u can use plain c++
int main(int argc, char* argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); // dump them :) for (int i = 1; i < argc; i++) { qDebug() << "param" << i << " is " << argv[i]; } if (argc > 2 ) { QString name(argv[1]); int id = atoi(argv[2]); qDebug() << "call func with" << id << " and " << name; w.MyLovelyFunction(id, name); // call some function in w mainwinow }
in this test i call it like
app.exe NAME 40
so string and int. -
Thanks for reply... it worked for me...
