    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?

          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

                      and tile_list is the ones to choose from ?

                      Dont worry. I programmed c++ for 20 years and it still kicks me ;)

                        yes, it is a list of Tile which is inheriting QLabel

                        Dont worry. I programmed c++ for 20 years and it still kicks me ;)

                        woaaaaa, me is about a year, and started this QT last week, i choose this for my tile engine's interface from SFML, i still have more ways to go !^_^

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

                            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.

                                  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.

                                      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.
