Hi

A very simple question , but I don't understand how to do it.

I'm using QTCREATOR. I created a form with designer.

Now I need to do some operation to this form by a new external *.ccp file.

I put Ui::Main *ui; public

Main::Ui->object->setText("mmmm" is visible but I get an error " Invalid use of non-static member"

How to do it??
