J2ME, why can't register CommandListener () from Canvas?

[Boki]

Hi All,

Why can't register CommandListener () from Canvas?

MyGUI extends Canvas
{
....
myMIDlet.myForm.setCommandListener(myMIDlet.myForm);
....
}


Error output:
setCommandListener in javax.microedition.lcdui.Displayable cannot be applied
to javax.microedition.lcdui.From


----------
How can I change my CommandListener from MyGUI.java to myMIDlet.java

Thank you very much for your help.

Best regards,
Boki.

Your Form object obviously does not implement the CommandListener interface.

Well, honestly, it's hard to tell since you're not cutting and pasting
the real text but typing it in.

Post the real text and we can help you.
