Subject: [PATCH] Fix hotkey functionality. Make spaces between horizontal
options the default attribute. Rename uber-function to lightbar_func. Add
object support. Create a new Lightbar object with: var lb=new Lightbar(); Or
optionally specify items like so: var lb=new
Lightbar([{text:"Option1",retval:"1"},{text:"Option2",retval:"2"}]); Add a
new option to the end of the items like this: lb.add(text, retval [, width]);
Clear the items array using: lb.clear(); Execute the lightbar with:
lb.getval([currentindex]); // Returns the retval for the selected item
Properties are:
xpos: Horizontal position of lightbar menu (1-based)
xpos: Vertical position of lightbar menu (1-based)
items: an array of objects each having the following properties:
text - The displayed text. A | prefixes a hotkey
retval - The value to return if this is selected
OPTIONAL Properties:
width - The width of this item. If not specified, is the width of
the text. Otherwise, the text is truncated or padded with
spaces to fit the width.
direction: 0 for vertical, 1 for horizontal.
Horizontal menus always have one space of padding added between
items.
fg: Foreground colour of a non-current item
bg: Background colour of a non-current item
hfg: Foreground colour of a current item
hbg: Background colour of a current item
kfg: Hotkey forground colour for non-current item
khfg: Hotkey foreground colour for current item
current: Index of currently highlighted item (ToDo: This should be passed by reference (how?)!)
align: If width is greater than the text length, a zero indicates the text
should be left-aligned, a 1 indicates it should be right-aligned, and
a 2 indicates it should be centered.
The Lightbar object will display a list of options and prompt the user for
a selection if lightbar_func() returns NULL.
Still todo... make the current value stay at the last selected one.
