hi friends,
i am new to qt. iam trying to develop real time data display app under qt-4. the application will receive data (some x,y,z etc) from on ethernet and display it with 1 sec update. my problem is, which qt class can i use for flicker free, flexible display. i also need to draw pixels of data on display with zoom facility.

can anybody suggest to do this in qt-4. code snippets, or sample applications will help me a lot to learn and develop my new application.

thank u very much in advance..bye

You can use Qwt (http://qwt.sf.net), QGraphicsView with a custom graphics item that represents a group of points, QGLWidget or plain QWidget (with this one you will have to do the zooming yourself).
