I've been working with friends for some time on a mind map program. Generally, the whole program is already set up, but we still lack a module that will save the map project in jpg or in a format for reopening the edition, etc. Does anyone have any suggestions on how to go about it and what is the best way to use it? We use the latest version of QT Qmake/C++
In general, I watched a few videos related to saving programs and there was nothing insightful in them. More like a lack of sense
