There are 4 tabs. In each on the list. Depending on the selected list item on the right, the content on the right (forms, buttons) should change.
1) I understand that each application header should have one application window? Each list contains about 10 items. Total 40 items in main.cpp?
2) What is necessary to contain the form? Each item in the 2.5 form list has an average of a total of 100 forms.
3) Is it possible to split each tab by classes or something like that and how will it look like? Can this be implemented on the QtQuick toolkit?
