[SOLVED] Qt - Auto detection of a file in application folder

Qt - Auto detection of a file in application folder

I have a sqlite database of my Qt C++ application. Suppose I located it on my default build/release folder and I also placed the database file on that same folder. I have login.h and login.cpp. I want that the application may auto detect the database and open it. I will only provide the name of database (Ex: mydb.sqlite).

Database.addDatabase("QSQLITE");
Database.setDatabaseName("I will only provide database file name here.like: mydb.sqlite");

I want that the rest of the directory should automatically detected and the database connection works perfectly. Suppose, I have the sqlite file in: C:/Qt/build-myapp-mingw-32/mydb.sqlite. I am taking a string variable called path. And I want that, the application automatically detect the whole path. And open the database connection.

Solution

You do not have to give the complete path to database to make it works. You can refer to the path from your build dir or maybe use :

QCoreApplication::applicationDirPath();

To get the path of your app and then navigate through your directories with .. ?
