After designing a form you should preview the final layout. To display a preview of your form select the Form menu from the main menu bar and then choose Preview. You can also press Ctrl+R.

The preview shows exactly what the final layout will look like in an application. You can also preview a form with various themes. Select the Form menu, choose Preview in and then select a style.

To simulate the effect of calling QApplication::setStyleSheet() in your application, change the Preview Configuration and specify a stylesheet. Select Settings and then choose Preferences. Next, select the Forms tab and enable the check box for Print/Preview Configuration.
