Hi and welcome to devnet,

Since you are using widgets in your project, did you add

@QT += widgets@

in your pro file ?

jugnu

Yes sir, I have added

SGaist

Then, can you show the content of your pro file ?

Just add the Kit for Desktop and remove the one from Desktop5 in the Project panel

Can anybody please tell me how to convert my project of Qt 5.3 to .exe file in windows.

jugnu

I got the .exe file in build option . But when I run .exe file it gives the error Qt5core.dll missing. How to resolve it?

IamSumit

Hi.
if you want to run your exe then just copy and paste from -C:\Qt\4.8.4\bin- ..../Qt/5.x/bin folder Qt5core.dll file.
hope this helps.

Edited@IamSumit :)

[quote author="IamSumit" date="1414649854"]copy and paste from C:\Qt\4.8.4\bin folder Qt5core.dll file.[/quote]You'll need other DLLs too, not just Qt5Core.dll. The link above describes one way of finding all the correct DLLs.

Also, you won't find Qt 5 DLLs in a Qt 4.8 folder ;)

I don't know in which version it started, but Qt has a windows deployment tool. I recently wrote up a "blog entry on it":http://bit.ly/qt5deploy. I found it worked quite well at gathering up all the .dlls needed to deploy an application.

I am writing output to a file using :

(*out) << variable_name ;

But i want to print it with 6 digit precision .How to do that?

jugnu

I got the answer
Thanx!!!1

I have three methods implemented in my project with tables.. I want that if user gives input to the table of first methods. Same inputs are copied to the
table of second and third methods. How to do that?

Check this web:

Anyway, I think you should post the question in other forum.
