How to know which key is pressed?

[TEPA6ANT]

KeyDown and KeyHit is good. But they return boolean variable. 
Is it possible to find out the current button pressed?

This used to not be possible without coding it yourself but I wonder how Leadwerks handles GUI edit boxes.  Maybe there's Lua code you can look at.

I think I earned the title of "bad programmer" )))

		local index
		for index=1, 255 do
			if window:KeyHit(index) then
				System:Print(index)
			end
		end

i used to do something like this...

this will only add keyinfo to the Keys table when a key is actually used.
to make it work you would need to add a call to PreUpdate() in your main loop.
to check a key's state you would call eg: IsKeyUp(Key.W) or IsKeyDown(Key.W).

function SetKeyboardInfoPack()
	local pack = {
		Keys = {},
		--
		FlushKeyInfo = function (self, resetHit, key)
			if key ~= nil then
				local nHit = 0
				if self.Keys[key] ~= nil and resetHit == false then
					nHit = self.Keys[key].hit
				end
				self.Keys[key] = {down = false, up = false, hit = nHit}
			else 
				local nHit = 0
				for key,value in pairs(self.Keys) do 
					if resetHit == false then
						nHit = self.Keys[key].hit
					end
					self.Keys[key] = {down = false, up = false, hit = nHit}
				end
			end
		end,
		--
		PreUpdate = function (self)
			self:RefreshKeyStates()
		end,
		--
		IsKeyDown = function (self, key)
			--create a key record if not already exists and check the keystate
			if self.Keys[key] == nil then
				self.Keys[key] = {down = false, up = false, hit = 0}
				self:RefreshKey(key)
			end
			--return keystate
			return self.Keys[key].down
		end,
		--
		IsKeyUp = function (self, key)
			--create a key record if not already exists and check the keystate
			if self.Keys[key] == nil then
				self.Keys[key] = {down = false, up = false, hit = 0}
				self:RefreshKey(key)
			end
			--return keystate
			return self.Keys[key].up
		end,
		Keyhits = function (self, key)
			--create a key record if not already exists and check the keystate
			if self.Keys[key] == nil then
				self.Keys[key] = {down = false, up = false, hit = 0}
				self:RefreshKey(key)
			end
			--return keystate
			return self.Keys[key].hit
		end,
		--
		RefreshKeyStates = function (self)
			for key,value in pairs(self.Keys) do 
				self:RefreshKey(key)
			end
		end,
		RefreshKey = function (self, key)
			if key ~= nil then
				if self.Keys[key] ~= nil then
					if window:KeyDown(key) then
						self.Keys[key].down = true
						self.Keys[key].up = false
					elseif self.Keys[key].down == true then		--last state down
						self.Keys[key].down = false
						self.Keys[key].up = true
						self.Keys[key].hit = self.Keys[key].hit + 1
					elseif self.Keys[key].up == true then		--last state up
						self.Keys[key].down = false
						self.Keys[key].up = false
					end
				end
			end
		end
	}
	--
	return pack
end
