What determines the default title for a QMessageBox?

Question

I want to change the default QMessageBox title to something else, so that I don't have to call setWindowTitle for every individual message box.

How is the default window title chosen?

Answer 1

Best way to do this is to subclass QMessageBox, e.g.:

class MyMessageBox : public QMessageBox
{
   MyMessageBox()  //<-- default constructor 
   {
    setWindowTitle("Default title goes here"); //QMessageBox function
   }
};

Use MyMessageBox everywhere in the code.

Answer 2

You could instead add a TARGET in the .pro file. e.g. add this line to the .pro file:

TARGET = MyApp

Thus "MyApp" will be applied both as the executable file name and also as default value for windowTitle of all QMessageBoxes in the entire project.
