Form support Display

i have a class extens from Form.

I wanna display something from this class like the following: Display.getDisplay(this).setCurrent(.....);

so i am getting the following error : getDisplay(javax.microedition.midlet.MIDlet) in javax.microedition.lcdui.Display cannot be applied to ( "the class that i am using").

So Form support Display or not.
