defining a widget from the ui file

[anda_skoa]

if you want your own QTextEdit subclass to be instantiated, you'll need to use the "promote widget" functionality.

Make a proper header/source implementation of your text edit class and then specify that class and its header in designer when using the promote feature.

Thanks. I can't seem to figure it out. I keep getting:

         textEdit = new textEdit(centralWidget);
                        ^

To copy to clipboard, switch view to plain text mode

    ~textEdit();

    Ui::textEdit *ui;

You called your class "textEdit" and you seem to have used the very same character combination as the variable/object name in designer.

Rename either the class or the object.

I thought it needed to be the same.
I got it working. Thank you!
