Hello. I'm writing a program to interface with a drawing library and output its results to screen using Qt (you might have noticed my previous post with a minimal example of input/output/error tabs). Upon clicking a push button "Execute", the app will send the input field contents to the library and write its output and error messages into the respective fields. If it successfully processes the instructions, the drawing output by the library in SVG format to a separate stream will be drawn using a QSVGWidget on screen.
Now the drawing library needs initiation before using it and cleanup while closing down the application. And since I have to connect the clicked() signal of the execute pushbutton to a executeCommands custom slot, I am subclassing MainWindow from QWidget, so I have included the library initiation into the constructor of MainWindow. My question: I am assuming that I have to include the library cleanup call in the destructor of MainWindow, but if I write a custom destructor, do I have to do any other delete calls to remove objects that are created on the heap in the constructor using new QTabWidget etc? If I don't have to call the library cleanup manually, could I simply leave out the destructor and the compiler will create the appropriate instructions itself? Thanks. -- Shriramana Sharma _______________________________________________ Interest mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/interest
