    welcome on board to Qt. its a nice frame work.

    Yes my first choice is wxwidget and windows form application, but signals and slots mechanism of qt makes me decide to choose qt

    Oh so its some sort of game editor your are making ?
    yes exatcly, like the rpg maker vx ace of steam

      Well IMHO Qt is more feature rich than wxwidget even I did like that also.

      Oh. Wow. thats a huge project. !
      So its an editor and and tile engine for making tile games. Pretty cool.

          IMHO = In my humble opinion
          Well I tested both and choose Qt.

          Would also be huge for me to make as single person if we are talking full
          game editor and engine :)

          I would have a good look at http://doc.qt.io/qt-5/qtscript-index.html
          Should be fast enough and quite easy to mix c++ and script.

              ok. to make it a full product? To sell or make games and sell ?

              -- We have group on skype do you want to join?
              Oh thanks for the offer but I only use skype at work as I sit in the living room and
              taking in mics drives the others crazy :)
              So no Team Speak for me either :)

              So you are a group of people making this?

                I want to sell the whole project. i dont want wasting time doing things that is unrelated to programming so i dont want to make games and sell.

                okay i see np.

                So you are a group of people making this?
                No im the only one making this. the skype group is a group of programmers experts and newbies. just for teaching things

                  Ok, a game maker product.
                  You should also consider how to handle support.
                  Takes more time than one realizes.

                  Ah, that way. Did not know skype has such forums/groups.

                  Really good luck with it.

                    oh no, im really bad at explaining things. i mean
                    you can create a conversation group in skype and invite people as many as you can. so i just found this group and then i joined

                    okay thanks again :)

                      my friends,i had a similar case and found this happens when you mix different versions of Qt to compile the project
                      they simply change the ui_*.h files or sometimes they empty it and thus this happens. Occured at least with me ..

                        @Lorence said:

                        grassyTile

                        What type is that ?

                        "use of incomplete type" often means a include file is missing
                        or you forwarded a class
                        like
                        class SomeClass;

                        And try to use it in a context where it needs to be fully defined.
                        Like adding to some template lists.

                        Not sure what you tried to define here ?

                        std::array<Tile,1> tile_list <---- ; missing here?
                        {
                        ui->grassyTile // heres where error coming from
                        };

                        @mrjj Thanks, you are right for saying that some header files might be missing.
