Hi the past few days I've been trying to make a simple gui using Qt4 to send a msg when pressing a button and to receive an int value from a topic and display it on a label or something.

I have successfully built the qt gui using rosmake as a standalone program but i dont know exactly which steps to take to integrate a ros node in the gui.

I looked through all the tutorials(eros qt and wiki) you have here and most questions. The eros examples do provide an idea but no luck with making it work.

Does anyone have any ideas, sample code or steps needed to combine a qt app along with ros node.

Thanks in advance!

To answer my own question. I overlooked one of the tutorials.

I just typed: " rosrun qt_create roscreate-qt-pkg qfoo "

That finally gives a clean working node with a gui!!

  1. $ sudo apt-get install qt-sdk - to install QT
  2. $ sudo apt-get install python-qt4 pyqt4-dev-tools - to install Python bindings for Qt cross-platform

After 1 and 2, Create required UI using QtCreater.

  1. $ pyuic4 -x filename.ui -o filename.py

  2. In filename.py integrate ROS code to interact with respect to UI Clicks

Please don't post link-only answers, this leaves the answer to be not self-contained (also seems a little spammy too tbh as you've post the exact same answer to multiple questions). Please update your answer with the all of the relevant information to answer the question.
