I'm trying to implement ALT + TAB behaviour.
I want to know when a user is holding the ALT key.
Why does this release function not work?
awful.key(
{},
'Alt_L',
function()
altHold = true
end,
function()
altHold = false
end
),
IMPRACTICAL SOLUTION:
awful.key(
{},
'Alt_L',
function()
altHold = true
end
),
awful.key(
{'Mod1'},
'Alt_L',
nil,
function()
altHold = false
end
)
This works, but any other hotkeys with ALT no longer work.
OTHER SOLUTION:
keygrabber.run(
function (mod, key, event)
-- Stop alt-tabbing when the alt-key is released
if gears.table.hasitem(mod, "Mod1") then
if (key == "Alt_L" or key == "Escape") and event == "release" then
-- Make it visible
if key == "Escape" then
-- Cancel client selection
end
else
-- Raise clients in order to restore history
-- raise chosen client on top of all
-- restore minimized clients
end
end
keygrabber.stop()
-- Pressed tab
elseif key == "Tab" and event == "press" then
if gears.table.hasitem(mod, "Shift") then
-- Move to previous client on Shift-Tab
cyclePreview(-1)
else
-- Move to next client on each Tab-press
cyclePreview( 1)
end
end
end
end
)
This is a slightly modified version from Troglobit:
https://github.com/troglobit/awesome-switcher/blob/master/init.lua#L470-L525\
This gets called when ALT + TAB is pressed.
While holding ALT, the next TAB press calls previewCycle()
function.
If ALT is released it selects the chosen client.
ESCAPE cancels the selection.
Random guess: When the key is released, the "alt" modifier is active, so you need a keybinding with Mod1
as modifier (is Alt
Mod1
? I'm not entirely sure). But of course, that key binding would then not react to key presses, so you need two.
