Summary: Allows locking
Version: 0.2
Last Updated: Fri Jun 22 00:59:06 EDT 2007
--]]
-- Usage:
-- F11 toggles the lock of keyboard close and resize on the currently active
-- frame.
-- META-F11 will save the name of the frame and lock it again in subsequent
-- sessions of ion.
--
-- You will need to rebind your close and kill bindings to use the
-- check_before_close and check_before_kill functions for this script to do
-- anything.
--
-- Adding
-- de.substyle("*-*-*-locked", {
-- background_colour = "yellow",
-- }),
--
-- de.substyle("*-*-*-*-locked_saved", {
-- background_colour = "white",
-- }),
-- to your theme's de.defstyle("tab-frame", {...}) style will cause locked and
-- locked+saved frames to be highlighted.
local locks = setmetatable({}, {__mode="k"})
local saved = {}

local name = frame:name()
if locks[frame] then
locks[frame] = nil
frame:set_grattr("locked", "unset")
if save and name then
frame:set_grattr("locked_saved", "unset")
saved[name] = nil
end
else
locks[frame] = true
frame:set_grattr("locked", "set")
if save and name then
frame:set_grattr("locked_saved", "set")
saved[name] = true
end
end
end
function check_before_kill(reg)
if not locks[reg] then
WClientWin.kill(reg)
end
end
function check_before_close(reg, sub)
if (not locks[reg]) and (not locks[sub]) then
WRegion.rqclose_propagate(reg, sub)
end
end
