Cursor and screen coordinates - ImageItem

[soofika]

I have added an imageItem to a form and displayed an image. Now I want to overlay a cursor and be able to move around and capture coordinates where the cursor is.

All my reading indicate that this is not possible directly with the imageItem or it's superclass. It seems like I have to create a custom Canvas item, with these capabilities. Before I go that route, I thought I might check with the experts here to see, to see if there is a better way.

Appreciate any help here....

Hi Soofi,

if you want to implement a cursor that can freely move around the device screen, then Canvas is the right option. Using it, you'll get total control on cursor movement and on its coordinates (since you have to implement them all by your own ).

Thanks Pit, Do you have any good code examples as a back drop. There is enough on the net on this, but if you know of some good example, it will be much appreciated....

Hi Soofi,

you could try to take a look at Apime, a Java ME UI framework that uses an approach similar to yours: so, it uses a mouse pointer to manage user interactions.

Apart from this, I'm not currently aware of any other related source code or examples, but I'll check around!

Hey Pit,

Thanks for the tip...

I downloaded Apime and was able to compile and run all the examples. It is very functional and seems to have all the components I need for my project. I like the fact that you can grab the entire screen for display. The controls however are clunky, but I don't plan to use many of them.

Are you aware of any one here who may haved used Apime for a real project, just to see if there are any shortcomings that I should be aware of.

Hi Soofi,

happy to know it helped. About real projects no, I'm not aware of any of them using Apime.
Anyway, if you want some feedbacks about single Java ME UI frameworks, you can look at this article:
