-- x.neo.pub.window @ sys-everest --
This API is the reference definition
of how the windowing system works in
KittenOS NEO.
Implementing this API, by definition,
makes your process the controller of
windowing on the system, which means
you control Icecap security dialogs.
...and that's why r.neo.* access is
heavily restricted unless the user
uses the Advanced Settings panel.
The API gives you a function:
(w, h, title) -> window
This function creates a window.
Window fields:
id: Window ID.
setSize(w, h): Changes the size of
the window, and sends the line
events (even if the size doesn't
change)
getDepth(): Returns the depth of the
screen the window is on.
span(x, y, text, bg, fg): Draws a
span onto the screen.
This function will error if the
Everest instance is dead.
(Others won't.)
recommendPalette(pal): If the window
is focused, sets the first #pal
palette entries to the given RGB
values.
This is meant only as a hint to
Everest, and may be ignored.
Returns 0.
close(): Close the window.
Events:
api, id, "key", ka, kc, down
api, id, "touch"/"drag"/"drop",
lx, ly, ix, iy, button
api, id, "scroll",
lx, ly, ix, iy, amount
api, id, "clipboard", text
api, id, "close"
api, id, "focus", hasFocus
api, id, "line", lineIndex
