Accessing objects in different forms

[jacek]

How do I create signal in designer? Just adding it in Object Explorer doesn't generate anything really.

You don't implement signals --- it's enough to declare them within class definition (the rest will be handled by moc).

Then just write:

emit someSignal( someParameter );

emit someSignal( someParameter );

To copy to clipboard, switch view to plain text mode 

And adding it to .h file in ".ui/" folder won't work cause all changes there are being ignored.

Then try the subclassing approach: http://doc.trolltech.com/3.3/designer-manual-6.html
