@cristian-adam Thanks for this ,
Ok i have foud how to add a folder to a project and yes , we need to edit the pro by hand ,
but what ? qt creator support sub folder project on project view and we can't simply use this basic feature ?
to add a subfolder, i pass to file view , i create a folder.
on the file system i copy paste the .h and .cpp in the new folder
and on the pro file i wrote :
SOURCES += [back slash]
... few lines ... [back slash]
foldername/files.cpp
an same things for headers
and my personal list to the minimum feture that must be already there :
add a multi selection feature
add a create / delete folder on project view
add drag and drop from file or list of file into subfolders
and drag and drop from external file explorer
add a hide Forms Group, like sources and headers
and update automatically
1- the pro to folow the changes mades on the tree views
2- the local #includes to make the project compiling
honestly i d'ont understant the utility of the file view, if the project view is corectly made we d'ont need a file view
