how connect in qt4....

[otortos]

Hi,
I was working with qt3 and it was so easy to me ( i am not a c++ programmer ) to write the code. I have one main screen, and a secondary. To call the second screen from the main in designer, i just press the menu "edit", "slots", "new function" and then write the code. I don't know how is in the new qt4, could somebody explain me a little?

Thanks.

Try reading FAQ

or Qt Designer documentation.

Well, i saw Qt Designer documentation....even i try the example with this erros:
ain.cpp: In function ‘int main(int, char**)’:
main.cpp:8: error: ‘imagedialog’ is not a member of ‘Ui’
main.cpp:8: error: expected `;' before ‘ui’
main.cpp:9: error: ‘ui’ was not declared in this scope
make: *** [main.o] Error 1

I did copy exactly the first example......

That's the reason i am posting this question.

Thanks

main.cpp:8: error: ‘imagedialog’ is not a member of ‘Ui’

Shouldn't it be "ImageDialog"? In C++ identifiers are case sensitive.

[otortos]

I did in both ways, ImageDialog and imagedialog....same error

[jacek]

Then check what is the value of your form's objectName property.

[otortos]

the name is the same: imagedialog

my files: imagedialog.ui, main.cpp

then i use qmake -project....then qmake and make.

the code of main.cpp is a copy of documentation.

[jacek]

Do you have #include "ui_imagedialog.h" at the top of main.cpp?

[otortos]

Yes, i repeat...is a copy of the documentation....the first two lines are:

#include "ui_imagedialog.h"
#include <QApplication>

[jacek]

Could you post the sources and .ui file as an attachment?

[otortos]

Yes, thanks for your help.....

[jacek]

I've fixed the main.cpp file --- class name must match the one from .ui file. If you create a template based on QMainWindow, you must use QMainWindow in your code.

I've also attached a simple example how to use .ui files in your code.
