Qt as only Gui Module (QMainWindow Params)

**radex99** · 29th August 2010, 08:32

Hello all!

This my first thread, I`ve just started my adventure with qt but i have problem I cannot not find the solutions.

Ok, I want to send parameter into qmainwindow, Beacuse I dont want to put my application Logic there. I will use not one, but three or four windows. I would like to have myApp manager which will call mywindows with parameter ( an object wchich holds data gathered and filled by window) to another module which will use this data and eventualy fill it and then this data will be set in Window. Is there any way to do this a i was trying to add my constructor to MainWindow but i`ve failed, Maybe to override QApplication in some way? And another thing is that i don`t want to use a singleton for my Data class.

Regards

Create a constructor with more parameters.

You have to create a constructor in the code of the MainWindow class. There already is one taking a QWidget pointer as a parameter. Add another (or extend the one that is already there) that takes the parameters you want. This is basic C++!
