Passing variables between forms.

[squidge]

There isn't a single way of solving this (like most problems)

Have a public method on your main window which accepts a username and password?

Or perhaps the login form could be given a structure which it fills in and returns.

Or you could use a singleton which contains such information and everyone accesses.

Hi squidge... could you show me an example of how to do this? If not, could your direct me to an article of how to do this.

I don't care if the code is messy, etc... i just want to get this to work. I'll tidy it up later

Thanks so much

What bit are you struggling with?

I assume you already know how to create a public method, thats basic C++.
The contents of that method - assigning parameters to class member variables, is also basic C++.

So the only part left is the actual call, and so you simply instantiate a copy of the login form from within your main window (either allocate it on the stack and call a function which doesn't return until the login dialog is closed, or use the 'new' operator to allocate from the heap)

This is not a Qt problem, its a C++ problem. How do you pass data around classes?

Ok I have successfully managed to do this now. Thanks so much for all your help. It really is appreciated

Edit:

Here is a link:

I found which helped explain things in a fair amount of detail. I decided to use the first approach as it was the easiest and involved changing less of my code. In future I think i will plan a bit more before starting a project

Thanks once again.
