Sorry, I've probably confused you by windows, they're not actually windows but rather QStackedWidget \
pages. Here's my example:

I'm writing an application to convert video, audio and image files. So in its basic form I want to have a \
main general class with a StackedWidget and separate classes which will draw different gui widgets on \
different StackedWidget pages. So

1. I have a MainWindow class - main class with QStackedWidget
2. class StartWindow - start page with 3 button: Video, Audio, Image
3. class VideoWindow - video converter page
3. class AudioWindow - audio converter page
3. class ImageWindow - image converter page

But I don't want to draw 4 pages (because only one will be displayed at a time and also to minimise the \
code). So I only create the start page and a second page based on what button has been pressed on the \
start page. And then just switch between the two by changing the StackedWidget page index. And when you \
return to the start page, the other page is destroyed. Confused? Well, what I can't figure out is, for \
example, 

1. How can I add a Video page to the StackedWidget from StartWindow if the StackedWidget itself is \
declared in MainWindow? How do you pass the page reference in the signal/slot which will do the page \
switch? 2. Or even simpler, how can I change text in the status bar from another page if the status bar \
is declared in MainWindow? How do you pass a reference to the main window status bar in a signal \
declaration? How can you pass that variable if it only takes types? \
