* Creates a frame and a button and prints the button's absolute position to the debug console
```lua
local mainFrame = basalt.createFrame():setPosition(3,3)
local aButton = mainFrame:addButton():setSize(8,1):setPosition(4,2)
basalt.debug(aButton:getAbsolutePosition()) -- returns 7,5 (frame coords + own coords) instead of 4,2

# onChange
`onChange(self)`<br>
This is a custom event which gets triggered as soon as the function :setValue() is called. This function is also called by basalt, for example if you change the input, textfield or checkbox (or all the different types of lists) objects.
Here is a example on how to add a onChange event to your input, and also another example for your checkbox:
```lua
local basalt = require("basalt")
local main = basalt.createFrame()
local aInput = main:addInput():setPosition(3,3)
local aCheckbox = main:addCheckbox():setPosition(3,5)
local function checkInput(input)
if(string.lower(input:getValue())=="hello")then
basalt.debug("Hello back!")
end
end
local function checkCheckbox(checkbox)
if(checkbox:getValue()==true)then -- or if(checkbox:getValue())then
basalt.debug("Checkbox is active, let's do something!")
end
end
aInput:onChange(checkInput)
aCheckbox:onChange(checkCheckbox)
