How to split a Form in two window

hi Friends,
WE a going to create a new form and want to show this form in two interrelated windows, like the following form

on the basis of the header the line level information will update,
so for get this type of design in your form you have to write three methods in from design.
1.
int mouseDown(int x, int y, int button, boolean ctrl, boolean shift)
{
    int ret;
    ret = super(x, y, button, ctrl, shift);
    return _formSplitterVertical.mouseDown(x, y, button, ctrl, shift);
}

2.
int mouseMove(int x, int y, int button, boolean ctrl, boolean shift)
{
    int ret;
    ret = super(x, y, button, ctrl, shift);
    return _formSplitterVertical.mouseMove(x,y,button,ctrl,shift);
}

3.
int mouseUp(int x, int y, int button, boolean ctrl, boolean shift)
{
    int ret;
    ret = super(x, y, button, ctrl, shift);
    return _formSplitterVertical.mouseUp(x, y, button, ctrl, shift);
}

after adding these three methods in your form design it will spilt  into two windows, now write your code for validation what ever is your requirement.
