[SOLVED] Invalid use of incomplete type 'class UI::MainWindow'

[mrjj]

@Lorence
Ok so it must be the tile_list statement.

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

[Lorence]

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

thanks for the help but i still get the same error

[mrjj]

@Lorence
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?

this is the error im getting

[mrjj]

@Lorence
Hmm it seems its "ui" it do not like.
Let me test.

[mrjj]

@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.

[Lorence]

ahh, Ui::MainWindow is defined in
#include "ui_main_window.h"

didnt think of that, thanks! but new error comes

@Lorence

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?

[Lorence]

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?

[mrjj]

@Lorence
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.

[Lorence]

then the list must be pointer type
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

[mrjj]

@mrjj said:
ok. Super :)

and tile_list is the ones to choose from ?

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

[Lorence]

and tile_list is the ones to choose from ?

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 !^_^

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

Oh so its some sort of game editor your are making ?

[Lorence]

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

[mrjj]

@Lorence
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.

[Lorence]

Well IMHO Qt is more feature rich than wxwidget even I did like that also.
yea, in other forum's debation, QT always win, whats IMHO?

Oh. Wow. thats a huge project. !
yes this is a huge project for me XD,
and i still got no idea about integrating script language into this project

[mrjj]

@Lorence
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.

[Lorence]

I see

Im planning to finish this as in 100%

thanks!

We have group on skype do you want to join?

[mrjj]

@Lorence
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?
