I need a cell, which is able to diplay an icon and an editable text  
together, for example in a browser or in matrix. Unfortunately the  
ButtonCell class supports icons with non-editable text. Is it right or I  
am missing something ?
How is it possible to overcome this limitation ?

I have been writing a Cell for the text object, to implement a Next
Mail like lip services, thinggy.

So far everything works execept saving and retrieving the file (and
also copying and pasting the lips)

The problem is in my (read/write)RichText: methods in my custom Cell,
here is the code:

- readRichText:(NXStream *)stream forView:view
{
/******
    printf("readRichText\n");
    lipsImage = [NXImage findImageNamed:"lips"];
    sound = [[Sound allocFromZone:[self zone]] init];
    [sound readSoundFromStream:stream];
    return self;
}

- writeRichText:(NXStream *)stream forView:view
{
    if ([sound duration] <= 0.0){
        printf("writing Empty Sound\n");
        [[Sound findSoundFor:"sound.snd"] writeSoundToStream:stream];
    }else{
        [sound writeSoundToStream:streamtream];
    }
    return self;
}

The problem seems to be the Sound object isn't writing the Sound file
to the stream, so when the program attempts to read the sound file
from the stream it hangs.

I know that the above method, doesn't result in a text file being
produced, this isn't a problem in my case.

Does anyone have any suggestions???
