[Qt-interest] Basic non modal dialog question

[Phil]

Again, thank you for reading this.

My application's main window class causes a non modal dialog to be 
displayed that looks to the user (me) to be a secondary main window. This 
dialog is always shown and displays data that are periodically sent from the 
application class. Like all classes in my application the display dialog class 
can receive data from the application class and return data, but only if it is 
interrogated. None of the slave classes have knowledge of each other or are 
able to initiate contact with the application class.

So, how is the application class made aware that the user has entered data 
into the dialog class? Should the dialog class not be a separate class itself 
but instead belong (if that's the correct term) to the application class? That 
way the normal signal / slot mechanism can be used and that seems to be 
the only answer. I don't think signals and slots work across classes.
