I dont' know about an actual "context" sensative menu (I have actually built any), but if you use the makeMenu(Menu menu, int instance) event of your screen, then when it is called, in there you can check to see if your listfield has focus, and if so, get text from the current line, and build a menu item on the fly.
Example of the MenuItem class and the makeMenu event ...
Code:
private class DynamicMenuItem extends MenuItem
{
private String menuName;
public DynamicMenuItem()
{
super("(na)",100,10); //don't call the constructor
}
public DynamicMenuItem(String menuText)
{
super(menuText,100,10);
menuName = menuText;
}
public void run()
{
foo(menuName);
}
}
protected void makeMenu(Menu menu, int instance)
{
menu.addSeparator();
//dynamically add menu items
DynamicMenuItem newMenu = new DynamicMenuItem(listField.getCurrentText());
menu.add(newMenu);
menu.addSeparator();
super.makeMenu(menu, instance);
}
This should get you going.
Cheers,
