The objects in a form are drawn in the order in which they are added.
Sometimes this is undesirable. For example, you might decide at a
later stage to put a box around some buttons. Because you add this box
later it will be drawn over the buttons, thus hiding the buttons (if
you put a framebox over a button, the button will be visible but
appears to be inactive!). This is definitely not what you want. The
Form Designer makes it possible to raise objects (bring them to the
top) or lower them (put them at the bottom). So you can lower e.g., a
box to move it under some buttons. Raising or lowering objects is very
simple. First select the objects and next press the function key
<F2>
to lower the selection or <F3>
to raise it.
Another use of raising and lowering is to change the order in which
input field receive focus via the <Tab>
key. Input fields focus
order is the same as the order in which they were added to the form.
This can become a problem if another input field is needed after the
form is designed because this extra input field will always be the
last among all input field on the form. Raising the objects becomes
handy to solve this problem. What really happens when a object is
raised is that the raised object becomes the last object added to the
form. This means you can re-arrange the focus order by raising all
input fields one by one in the exact order you want the focus order to
be, and they will be added to the form in the order you raised them,
thus the input focus order is what you intended.
