Graph display in QT/Embedded

[hvreddy1110]

Hi,
I am new to Qt.
Can any one tell me what is the difference between Qt .Qtopia and Qt embedded.
Because in my LTIB for ARM11 processor has an option to select Qt/Embedded or Qtopia.
I want to develop an application which will display some graphs (Like ECG) using ARM11 processor.
If i want to display graphs do i need to use Xlib in my target or no need .
As per i know QT/Embedded does n't require Xserver/Xlib .But using QT/Embedded is it possible to display
ECG type of graphs.If yes how?
Kindly help me in this regard.

Thanks in advance
Regards,
Harsha

In Qt3 Qtopia was a desktop environment for PDAs build on top of Qt/Embedded. With Qt 4 the modules are bundled in different way, where the name Qtopia has been reused for both (and new) packages.

For displaying graphs you could try Qwt (http://qwt.sf.net).

It is reported to be working with Qtopia Core ( formerly known as Qt3/Embedded ), but has not been optimized for embedded systems. I recommend that you build the Qwt examples first and check them on your target system.

HTH,
Uwe
