@Hbomb_79 you just need to have the buttons action set as a function.

button = gui.createButotn( "Button", function() doSomething() end )
button:trigger()

Just found another bug: If you use multiple dialogboxes in one program, after clicking "ok" in one dBox, in each following box you can click whereever you want and it will still continue.

Looking at the code I noticed that ret is not local, so everytime you call box:draw(), ret will have the value of the last dBox.

I didn't test it with y/n-boxes, but there will be the same problem. I solved it with declaring ret as local at the start of the draw-function, so it will be deleted after the function finished:

function Boxs:draw( x,y,width,color,bcolor,tcolor )
  local ret = nil
  ... --all the other stuff here
end

Can you explain that button:trigger() i want it so i can have a menu that displays several buttons, when i click on one it clears the screen and loads a function ive already made... the function is called bulkHead() how would i do this?

WOW, this is VERY useful! Thanks, I suck at GUIs!

[hbomb79]

Can someone help me out, this is what im having issues with, i have NO idea how to use this api...

this is the code.... It crashes and turns red without even clicking the button as well....???

os.loadAPI("/api")
function hi()
  print "Hi"
end
button = api.createButton ("button", fucntion() hi() end)
button:draw(1,1 5, colors.green, colors.white)
button:toggle(colors.red,4)
button:trigger()

It then gives me this error "api:70: attempt to index ? (a nil value)"

@Hbomb_79

Change:
os.loadAPI("/api")

To:
os.loadAPI("api")

That wouldn't make a difference. The error occurs in the API, which means it's been loaded.

[newcat]

There is a spell mistake. It needs to be

function() hi() end

You have written fucntion().

[hbomb79]

Oh wow, what a silly mistake... Thanks

I just tried buttons (first & last thing I tried), and I got this error:
Just downloaded the API so latest version.
[string "gui"]:70: attempt to index a nil value after running the following code

os.loadAPI("gui")
button = gui.createButton(  "button", function() print("Hello World!") end ) --#This creates a new button with a function that when triggered will print "Hello World!"

button:draw( 1,1, 5, colors.green, colors.white ) -- #This draws the button at (1,1) with a width of 5. The first color is what the buttons color will be and the second color is the text color

button:toggle( colors.red,4) --#This toggles the buttons color to red for 4 seconds (If you leave the second argument as nil it will just toggle the button)

button:trigger() --#This triggers the buttons function

gui.detect( 1,3,true ) --#this checks an array of all the buttons you've defined and returns the name of the button. If you also set the third argument to true it will trigger that buttons action

It errors on button:trigger()

I started to work on my old GUI project again and fixed the problems with the textboxes I mentioned in one of my older posts. Here is the new version:

Spoiler

function newTextBox(x,y,length,bcolor,tcolor)
  typed = {}
  alphabet = "abcdefghijklmnopqrstuvwxyz"
  local shift = false
  ... --all the display stuff here
  typing = true
  term.setCursorPos(x,y)
  while typing do
    event,key = os.pullEvent()
    if event == "key" then
	  if key >= 2 and key <= 10 then
	    table.insert(typed,tonumber(key)-1)
	  elseif key == "10" then
	    table.insert(typed, "0")
	  elseif keys.getName(key) == "enter" then
	    typing = false
	    return string.gsub(table.concat(typed,""),"space"," ")
	  elseif keys.getName(key) == "space" then
	    table.insert(typed,keys.getName(key))
	  elseif keys.getName(key) == "period" then
	    table.insert(typed,".")
	  elseif keys.getName(key) == "comma" then
	    table.insert(typed,",")
	  elseif keys.getName(key) == "backspace" then
	    table.remove(typed,#typed)
	  elseif keys.getName(key) == "leftShift" or keys.getName(key) == "rightShift" then
	    if shift == true then shift = false else shift = true end
	  else
	    key = keys.getName(key)
	    if string.find(alphabet,key) ~= nil then
		  if shift == false then
		    table.insert(typed,key)
		  else
		    table.insert(typed, string.char(string.byte(key) - 32))
		  end
	  end
    end
   
    ... --all the other stuff here
  end
end

I found no way to pull an event like "key_up" therefore you can just toggle shift at the moment. Maybe that will be implemented in a later version of CC...
I hope you update your API so all the people who want to work with that awesome API have that fix without having to manually paste it into their version.

What data do you get from the sensor? Some example values would be cool

Looks, really good, I'm going to use this with my OS. Am I allowed to upload this to github and redistrubute it with the download of my OS if I give full credit of it to you ?
