Dear Sir,

My Project is a simple one.
I have to build the interface using canvas.
and almost all the interface is done, except when an menu item is clicked , it should display a textfield where a client can enter some inputs.

I have almost done it.

I did as you said in the earlier post.
Can i fill some color on the form so that the UI is inconsistency.

Please help me.
If you give me ure email id i would like to share my project with you.

Thanking you,

Robin Thapa

if (c == backCommand) {
CanvasListMidlet.quitApp();
} else if (c == selectCommand) {
if (selectedIndex == 0) {
/// here i wish to call another canvas which consists of another List as in the examples class as:MessagesMenuScreen
// i tried calling another canvas class but i am not able to get it done.

Dear Sir,

I am really thankful to you for your help and Support.

Peter Miklosko wrote:When you start screen make one of the option highlighted-selected by default (draw rectangle with perhaps different colour then background and change style of text, bolder, different colour or font), have variable that holds a data on currently selected option. Create method for traverse and rest should be easy to finish once you know which option is selected.

PS: there is small difference on returned button press between emulator and real device. One return for example UP and the other Up. So watch out for these...

Could you please just help me with my codes just to select the image? i mean can you help me to make a button kind of over those three......
