It doesn't make bad .h files to store a pointer to each object you create. If 
you really have a good reason to do that, you can ask the parent object for 
its children using this->child( "name1" ) and casting it into a QPushButton 
but this is of course much slower than using secondButton->blah().

Best regards,
Harry
