[Solved] Problem with .ui file

Swinetha

hi...

I am coming with silly problem but it is irritated me from 2hours.

In Qt creator, I am open the project which is already exist one or new one it's fine but when I click on .ui file total QT creator is closed. what is the problem am not getting?

sierdzio

Which version of Qt Creator are you running? What operating system are you on? Have you tried running Qt Creator from terminal to catch any error messages?

Swinetha

I am running QT4.8.1 version in Ubuntu 12.04 version.

I am run any qt project From QT creator it does not gives any error but if I want to open ui file it close the qt
and now I run the project from terminal also it does not catch any errors It is run as usual

uninstall the qt creator and re- installed but even It is same

sierdzio

I've asked about Qt Creator version, not Qt version. Try installing the newest Qt Creator from Downloads pane.

Swinetha

I am installed this from Ubuntu software centre QT4 It showing v2.4.1(default).

sierdzio

Yeah, that is very old. Try a newer one, installing precompiled QtC is very easy (compiling it yourself is also very straightforward, to be honest) and it will not break your current setup (you can have numerous QtC installations running in parallel, although usually there is no need for that).

Swinetha

can you give the information about newer one

sierdzio

See the big "Downloads" link at the top of this page? Ok here's a "direct link":http://qt-project.org/downloads#qt-creator for you.

Swinetha

am asking about version name

sierdzio

There is only one version listed on the downloads page (2.7.1). If you wish 2.8 is in beta currently, for me it is stable.

Swinetha

Is there any Installation procedure?

sierdzio

Yes, standard unix one: make the file executable, then run it.
@
chmod +x downloadedFile.run
./downloadedFile.run
@

This can also be done from the GUI, of course.

Swinetha

thank you for giving your valuable time.

Did you know the reason for this one? If it is, then let me know the problem

Swinetha

Swinetha

Completed the installation of qt. but in my qt it is not showing qwt widgets. which already installed in my system how can I include qwt widgets in Qt (not libraries )

For installing a programm you should have be a root or handle like a root. Write sudo bash in the shell and entry the root password. Like this:
me@me-laptop:/$sudo bash
[sudo] password for ashegh:
root@me-laptop:/#

after this you can write th top commands:
root@me-laptop:/#chmod +x downloadedFile.run
root@me-laptop:/# ./downloadedFile.run

Qt does not require root permissions.
