    Commandlistener / eventhandler

    Hi,
    i'm trying to solve some aplication and want to siplyfize its layout
    it has some form transitions based on choice elements selected and commands append to forms

    on some forms i have only 2 choice elements.
    is there any solution, that user will go to choicegroup (by clicking arrows) and than with joystickpush (ok button) when he chooses the option i will set some eventhandler/commandlistener and directly switch to another form based on selected index?

    or any other solution for easy one-click element choice and transfer to other form?

    <<something like on web pages, click on link > goes to this page>>

    i have also basic commands on context buttons(under display) for going to Help form, setting form, exit aplication and so, that's why i cant add here other commands for next and prevoius page, because user will have to push out the menu with all this options

    also i want to use basic forms with text, string items and choicegroups, donet need any graphical content.
    mayby some methods from gamecanvas for using button_fire

    any solutions?, help?, or source codes using this? I haven't found

    thanx in advance

    (basic midp 2.0/cldc1.1 application)

    Lightbulb Re: Commandlistener / eventhandler

    Hello

    Give a check to:

    1. The interface ItemStateListener
    2. The method of the class Form
    Code:
    public void setItemStateListener(ItemStateListener iListener)
    That interface will provide you a means to detect any change of the state of a form item.

    Here is a link to the MIDP 2.0 API if you don't have it locally
