How can I make invisible close ,maximized and minimized buttons of ui form

[mcosta]

I don't think is possible to set WindowFlags in Designer.
I think because the UI file can be used as stand alone form or can be embedded in existing forms

Thank but I can not do

Try Setting the Maximum , Minimum Width and Height to same value.
but still the close button will be visible.

Why you can't use QWidget::setWindowFlags()?
