and also ui_Dialog.h, ui_ConvertDialog.h and main.cpp which contents are obvious. Here are those problems:
Dialog.cpp:18:error: expected ) before * token
Dialog.cpp:18:error: expected , or ; before * token
In bool convertDialog.h:
beaufortBox undeclared (and the same with others e.g. knotBox)
Dialog.cpp:99:error: expected primary expression before -> token (im reporting about it only once, I've got much errors like this)
Dialog.cpp:94:error cannot call member function void Dialog::displayConvertDialog() without object

When I try to solve the undeclared e.g. knotBox by calling Dialog::knotBox I reach error that undefined reference to Ui:ialog or something like this because I didn't call the same to ui part of this class. How to solve all this problems? Regards
p.s. I had to split the text between 2 posts
