Hi
Ok, that is pretty strange.
i assume normally around the green area, there would be
some buttons or similar.
I have this strange feeling it might be related to unity.
Would it be possible to try to run the exe on other linux ?

@mrjj Thank you .. Yes I have try..but i dont get any solution for this.. any another solution for display widget on gui after run?.I cant understand why this issue is generated..

@vaibs
Hi
Try to run some of the samples that come with Qt or
a new blank GUI project to see if that shows.
I have not seen anything like this before.

Hello,
AS I read you want to install qt 4.8.1 First you have to download qt4.8.1 and place it on desktop.
Then you have to open the terminal in your Ubuntu and enter your path of the desktop.
Then you have to install some required dependencies
sudo apt-get install build-essential check install
After that, You have to extract that qt4.8.1 file using commands
ar -xvzf qt-everywhere-opensource-src-4.8.1.tar.gz
Then go to the extracted folder using
cd qt-everywhere-opensource-src-4.8.1
And then run Via follow these

• ./configure
  make
  sudo check install
  Then you can install it via apt
  sudo dpkg -i path/to/output.deb
  Change path/to/output.deb to the path of the created .deb file.

Hope this will help you.
Thanks

Hi
so what was wrong first ?
Since there was nothing on the sceen ?
and what did you do to make it work ?

[vaibs]

@mrjj Wrong with environment ..
go in etc/environment
then add QT_X11_NO_MITSHM=1.
then screen show all widget
Thank you for your support..
