hi all,
i'm trying to compile my project, that i have made under linux, in windows
graphForm::graphForm(QWidget *parent) :
QMdiSubWindow(parent),
ui(new Ui::graphForm)
in the code with red color i get the following error, although i have no problems in liunx
Fehler:C2512: 'Ui::graphForm' : no appropriate default constructor available
does onybody know what could that be
any help will be apreciated

I think wysota meant the automatically generated class code, created by uic from the form .ui file ( form.ui should give you ui_form.h ).

i have shortened the code

no there is no constructor.
should not qt be portable. as i have seen one must change his code to get it compiled in win (in my case). i have solved another problem, witch i didn't have in linux.

Are you using the same version of Qt/Creator on both systems?
Are you attempting to use automatically generated files created on Linux under Windows?
Have you done a complete 'make clean' of your project and regenerated everything from scratch?
Are you sure this code compiled under Linux? 'cause it doesn't look like it should; there's no constructor corresponding to the object you're trying to construct in the initialization routine.
To answer the question you've repeated several times now: yes, Qt code is, for the most part, portable without change between Linux and Windows. The only exceptions are sections of code that are clearly platform-dependent such as calls to Windows or Linux OS routines or similar resources. I've ported several large programs between the two systems and have never once had to rewrite code.

But I think there is a default, auto-generated no-argument constructor like for any other C++ class without other constructors, so new Ui::graphForm should be ok.
I agree with SixDegrees, you should rebuild everything from scratch.
