Hi there everyone, I'm new here and I'm new to blackberry development.

For a student project I'm working on, I have a 2D array of ButtonFields, (which I may change to LabelFields if its easier) which I am using to create a Sudoku grid.

I understand it's really basic but I want to the user to be able to just scroll through the 2D array to a particular cell and be able to type in a number using the keypad to instantly change the label of the ButtonField or LabelField, ie their guess of the Sudoku.

I'm really having trouble as I'm not familiar with how the blackberry accepts user input and how this can be used with the setText method.

So essentially i'd like some sort of way of determining which cell is currently selected (without it being clicked) and then for this currently selected cell to have the setText() method applied to it

Can anybody help me? I can post up code if it helps but I'm not sure it will as you'll al understand how basic it is.

Thank you in advance and I hope I can return the favour soon

You should take a look at GridFieldManager here:

In your MainScreen class override the method keyUp(int arg0, int rg1)and inside it you can call the method getFieldWithFocus(); and set the text.

I'm already using gridfieldmanager to create the grid, but thanks for your suggestion

Thanks for your help, I'm doing something along those lines now

OK, then what is your question exactly?

Sorry if I didn't make myself clear, there was a lot of preamble to my actual question hehe

maybe you could help me with my other problem? I can't post the link up but its in the same forum. Thanks for your help

Your manager should tell you which field has the focus, right?

Field field = Manager.getFieldWithFocus()

Or, if you have nested managers, you may need to call

Field field = Manager.getLeafWithFocus()
