Alright. Thanks. That sounded like a lot of work so I scanned through the application's many features and found "Run Settings" has something called "Main QML file" that seems to operate the way I expect.
Hello @JKSH thanks for your response, I already solved the issue, the problem was in qml.qrc file, i just have to edit and update the file list with new icon images, then rebuild the project again.
Because the qml files you have are compiled in your application when using qrc. That's why you have to build your application before you can see the changes.
