I wanted to use the app in a different theme so i cloned it in qt creator 5.12.10 (5.12 MSVC2017 64 bit) and i opened the pingviewer.pro file and clicked the green run button , the app didn’t run . there was few errors like syntax and path errors. And also i tried opening the qml files in the designer , there also no luck . what i want is open the app and edit its font , color, theme etc. is there any way to do or since it has .dll is it only possible to view and install it? i’m a noob in qt . any suggestions and help would be grateful.
