If not... could anybody tell me how can I do a good looking menu or form?? Or just some advice. Please I need help!! Thank you very much!

hi,

list is a set of items,
so if you has an array of items you could show them on view by drawing,
with canvas that is just all "draw" methods from graphics object,
e.g. "menu list' is also a list:

not easy,
I've don't remember if source files are posted here at all,
You can however find examples of such custom low-level List implementation by looking into Nokia sample source files that comes with Nokia SNAP SDK:
http://www.forum.nokia.com/info/sw.n...lient_SDK.html
Nokia has customized List drawn on Canvas build upon custom graphics-items (using images and drawn strings), but that's rather hard to start with,

Thanks a lot Peter,

Let me see if I understood... So if I want to make a good looking list, I could build the list as a normal List and then draw each element with Canvas, right?
Ok, another question: If I want to select each Item of my List. Should I handle key events like going up and down on the list and then redraw my Canvas to simulate a selected or focused item?? If not could you help me again. Sorry if my english is not the best but I´m from Spain I hope you can understand me. Thank you again for your help

regards

hi,
yes, exactly, you need to handle key events to reflect element being focused on canvas and in your "model" (could be as simple as array and current index reference) - so when for example FIRE is pressed you know exactly which item is currently selected on screen, when DOWN/UP is pressed you advance menu item selector,

Hi!

Thank you very much again Peter, you helped me a lot! But now I have another doubt, each time I move the cursor over the screen, should I repaint the whole canvas, or is it possible just to redraw the selector cursor? So the drawing would be faster. Thanks again for your time

hi,

look into Canvas and Graphics objects methods/properties,
you can draw only single item on canvas that way updating only part of screen, or limit clip rectangle to force redrawing only on part of the screen, etc,
thanks,
