    grassyTile is of type Tile that is inheriting QLabel

    Not sure what you tried to define here ?
    i dont know how to list intialize an array on constructor so i decided to do it in side a class definition

      and "tile.h" is included ?
      in mainwindow.h

      do you mean like ?
      std::array<std::string, 2> strings = {{ "a", "b" }};

        yes i got all i need included.

        do you mean like ?
        std::array<std::string, 2> strings = {{ "a", "b" }};

        yes, in the mainwindow.cpp i can freely use ui->grassyTile; without error.

          Ok so it must be the tile_list statement.

          Would it like
          std::array<Tile,1> tile_list {{ui->grassyTile }};

              Ok, and you are 100% it knows the tile type here?
              you can declare one over the tile_list and it will like it ?
              Tile *Test;

              One thing I wonder, you say
              std::array<Tile> and not std::array<Tile *) or & so it must make a copy of
              it (the tile). Is that the effect you want?

                    @mrjj
                    ahh, Ui::MainWindow is defined in
                    #include "ui_main_window.h"
                    which is included in the CPP file so the type is not fully defined so you cannot say
                    ui->Somename
                    as Ui::MainWindow is not defined yet.

                    moving
                    #include "ui_main_window.h"
                    to the minwin.h file allows it but not sure if it will confuse Qt Creator.

                    Also it will complain about not being able to convert Tile to Tile * as list is not pointers and ui->grassyTile will be.

                        Yeah, it tries to construct a new Tile to go into the list.

                        Can I ask if you want a list of pointers to tiles you have on screen or
                        a list with new Tiles that has nothing to do with those on screen?

                          sorry for the late reply.

                          i just want a list of tiles to choose from.

                          but QT disabled the copying of QLabel,
                          so i really need to have a pointer of tiles?

                            heh 9 mins is not considered late ;)

                            then the list must be pointer type or it will be new ones and not the ones on screen.

                            so
                            std::array<Tile> should be std::array<Tile *> or std::array<Tile &>
                            so its the ones on screen and not new ones
                            Yes you must at least use & as it must "point" to the real one.

                              yea, i edited my last reply

                              it will be new ones and not the ones on screen.

                              it is the ones on the screen, there will be a list of tiles on the screen and the user will choose what tiles they want to render

                              *so
                              std::array<Tile> should be std::array<Tile > or std::array<Tile &>
                              so its the ones on screen and not new ones
                              Yes you must at least use & as it must "point" to the real one.

                              thanks!!!!!!!!

                              all my problem is fixed :) I have not coded for weeks and C++ is already kicking me damit

                                        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 ?

                                        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.
