Error Field Info Has Incomplete Type

down vote favorite Can't compile my class. Getting error: error: field 'filename' has incomplete type If I change QString filename to QString *filename, error goes off.. but I need to have QString filename. process.h: #ifndef PROCESS_H #define PROCESS_H #include class Process { public: int pid; QString filename; Process(int pid, QString filename); }; #endif // PROCESS_H process.cpp: #include "process.h" Process::Process(int pid, QString filename) { this->pid = pid; field has incomplete type array this->filename = filename; } What's wrong? c++ qt share|improve this question edited Jul 8 '14 at 6:38 Korchkidu 1,70732648 asked Jun 14 '13 at 11:26 Denis Kildishev 330412 2 That code looks fine, I think the problem must lie somewhere else. Are you sure you can reproduce the problem with this exact code? –hmn Jun 14 '13 at 11:31 1 Is that the whole header? If not make sure you don't have a forward declaration for QString class between the QString header include and the Process class declaration. –Zlatomir Jun 14 '13 at 11:32 It's the whole header. If I create empy project everything works fine. –Denis Kildishev Jun 14 '13 at 11:56 But in my project there are lots of file, that use #include "process.h" and #include . –Denis Kildishev Jun 14 '13 at 11:57 In this case Zlatomir is right. Something forward declares your class and does so before including your header. Search your code for "class QString" and see if you can avoid this. –user2471020 Jun 14 '13 at 20:16 | show 1 more comment 2 Answers 2 active oldest votes up vote 3 down vote In my expe

It seems you are mixing two forms in one, and the UIC compiler gets lost somewhere. If I'm not wrong, in your project you only have one form .ui, whose name is ListDialog. Look inside ui_dialog.h and you may find something like @namespace Ui { class ListDialog: public Ui_Dialog {}; } // namespace Ui QT_END_NAMESPACE@ So when pressing CTRL and clicking over your ListDialog in @namespace Ui { class ListDialog; //click this one class EditDialog; }@ Qt must jump to that part of the code. If you repeat this operation with your EditDialog, Qt will remain in the same file. That means there is no .ui file for your EditDialog. This should be the reason why you get that message. So, go on, create a new form and be sure to specify its name correctly. Then include the autogenerated header ui_whateverNameYouUsed.h it in your .cpp and re-compile. If you have any doubts, just ask. Good luck! Reply Quote 0 joergpauly last edited by What I see: You instantiate an object of a class in it's own declaration. I may be wrong, bu

I've been having a problem while trying to insert a struct inside of a struct! The initial idea was to have a single struct with many int and char fields, but I decided to put those fields on a separate struct and insert this new struct on the first one. Here's how it ended: typedef struct aviao { struct informacao info; struct aviao *prox; }Aviao; typedef struct informacao { int combustivel; int estado; int tempovoo; char compania[2]; char rota[3]; }Informacao; Example: If I declare Aviao a, b; I can copy their properties just by doing a.info = b.info I mean, it would be so if the compiler wouldn't give me the following error: "field `info' has incomplete type " wich shows up on the 3rd line of the code that I posted here. I googled this error and it seems to be the same thing that happens when you declare an array without stating it's size. But hell, I can't seem to relate this kind of error with anything that happens on my code I would be glad if anyone could give me a hand at this one. Cheers! TaviO!

With pointers, you don't have to define things before using them, but you still have to declare them.
