Qt and high dpi screens

I've read several articles on this. So I have a Dell XPS 13 and changed the size of text, apps and other items to 200%

enter image description here

But I guess my question is the following. When I launch the application through Qt Designer everything looks good:

enter image description here

enter image description here

But when I run the application outside of the Designer( meaning just double clicking the application to run it), the size is different:

enter image description here

enter image description here This toolbar is actually smaller than what the screenshot shows. So my question is there a setting I can set my application so when I launch it outside of the Designer it will look like when it was launched from the Designer?

For certain widget classes you can try to provide size measures relative to its font size with the stylesheet:

pMyWidget->setStyleSheet(
   "MyWidget {"            // What type is it? 
       "min-width: 80em;"  // If the dimension
       "min-height: 40em;" // attribute is
       "width: 160em;"     // applicable
       "height: 80em;"     // to this type.
       // margin:          // See the list
       // padding:         // of related
       // spacing:         // attributes
"}");

That "em" refers to capital "M" font size AFAIR. The tricky part here is what actual MyWidget type is and if you can apply a stylesheet like that. You can probably omit the widget type in style MyWidget {} but leave the contents yet it supposed to modify all the widgets that that one is parenting.
