Basalt/docs/events/otherEvents.md

There are also other useful events you can listen to:

onChange

onChange(self)
This is a custom event which gets triggered as soon as the method :setValue() gets called. Not only you can call :setValue(), also input, checkbox, textfield, ... objects call them internally.

Here is a example on how to add a onChange event to your input, and also another example for your checkbox:

local basalt = dofile("basalt.lua")

local mainFrame = basalt.createFrame("myMainFrame"):show()
local aInput = mainFrame:addInput("specialInput"):setPosition(3,3):show()
local aCheckbox = mainFrame:addCheckbox("specialCheckbox"):setPosition(3,5):show()

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 us do something!")
    end
end

aInput:onChange(checkInput)
aCheckbox:onChange(checkCheckbox)

onResize

onResize(self)
This is a custom event which gets triggered as soon as the parent frame gets resized.

Here is a example on how to add a onResize event to your button:

local basalt = dofile("basalt.lua")

local mainFrame = basalt.createFrame("myMainFrame"):show()
local aButton = mainFrame:addButton("myButton"):setPosition(3,3):show()

local function onButtonResize(button)
    local width = mainFrame:getWidth()
    button:setSize()
end

aButton:onResize(onButtonResize)
