/**
|
|
|
The main class used to get an KMultiFormListBox widget.
|
|
|
|
|
|
The KMultiFormListBox widget consist of a sub-widget which is repeated a
|
|
|
number of times, it is up to the end user to determine the number of times
|
|
|
the sub widget is repeated, and he may require an additional copy simply
|
|
|
by pressing a ``Add'' or ``More Entries'' button. The KMultiFormListBox
|
|
|
widget has two different faces (i.e. two different end user
|
|
|
interfaces). One (Windowed) will show a listbox from which the end user
|
|
|
can access each subwidget containing data by pressing the LMB on a name
|
|
|
for the element. The other face (MultiVisible) shows all the subwidgets in
|
|
|
one huge ``Listbox''.
|
|
|
|
|
|
To use the KMultiFormListBox widget you must create a class which is inherited
|
|
|
from the @ref KMultiFormListBoxFactory class. This new class must override the
|
|
|
function `create'. This function must return a freshly made instance of
|
|
|
the class @ref KMultiFormListBoxEntry (or a subclass of this). The KMultiFormListBoxEntry
|
|
|
instance is the one inserted into the KMultiFormListBox widget (one instance for
|
|
|
each sub widget in the KMultiFormListBox widget).
