e-mail addresses from the pkg-descr file that could reasonably be mistaken for maintainer contact information in order to avoid confusion on the part of users looking for support. As a pleasant side effect this also avoids confusion and/or frustration for people who are no longer maintaining those ports.

JComboBox is a composite widget that contains a text Label or Entry, a
|
|
Button, and a popup Listbox. It performs the same sort of tasks that can be
|
|
accomplished by several other Composite widgets. Some such as BrowseEntry
|
|
and Optionmenu are part of the standard Tk distribution, and there are many
|
|
others available in CPAN.
|
|
|
|
JComboBox borrows features from the Java Swing component bearing the same
|
|
name, but falls short of being a true clone. Many of the methods and the
|
|
general look and feel should be familiar to java developers. JComboBox also
|
|
combines several features offered by many of the other "Combo Box"
|
|
implementations, and works in two modes: editable and readonly.
|
|
|
|
In readonly mode, JComboBox offers similar functionality to Optionmenu. It
|
|
is basically a labeled button that activates a popup list. An item from the
|
|
list is displayed on the Button when selected.
|
|
|
|
When editable, JComboBox somewhat resembles BrowseEntry. That is, the
|
|
widget is composed of an Entry widget with a Button to the right of it. As
|
|
in the editable mode, the Button activates a popup Listbox from which a
|
|
single item can be selected.
