The easiest way (using Designer) is to open your main window, drag a
QWidgetinto it, and position/name theQWidgetlike you would your custom widget. Once that is done, right-click on theQWidget, and select Promote to…. A dialog will show up with the widgets it can be promoted to. At the bottom of that dialog, you can add a new widget for promotion. Type in the class name and include file information, and add that widget. Then select the entry in the list, and click the Promote button.At the end of this process, you should be able to recompile, and your custom widget will be where you placed it in the main window.
