Dear Experts,

Regarding blackberry UI api's i have some Questions.

1-i see that the MainScreen extends FullScreen.

is that mean i can't make it not full screen and if so that mean i should extend screen direct if i want my application UI not full screen ?

2- i have a list added to my screen , can i have small icons beside each item in this list...i try to add it but there is no public funciotn i saw on the list give me the ability to do that.

and if there is work around please specify.

Iam using ObjectListField and adding String object on it.

3- i see in the mainscreen that i can specify background, that mean is there ability to fill colors in the background , like overrid the paint function and draw the background color, and the same issue with the list like specify the text color and the selection color.

Thanks very much for help.

You can add icons to your list elements using drawListRow() method. Use graphics.drawBitmap() to draw image in each row.

Yes you can specify background color of objectListfield.

Use MainScreen or FullScreen as your requirement. MainScreen will handle all the events which are not handeled by app like navigation, scrolling and touch events.

You can do this in version 4.6.  Have a look at the "Working with indicators for an application" in the 4.6 JDE Development Guide. You can use this link

You can also refer to the JavaDocs for net.rim.blackberry.api.messagelist.ApplicationIndicator.

you have to extend screen, there is no such flag on the mainscreen.
