__NOTOC__
This function allows you to bind a function to a DxElement's render handler.

==Syntax==
<syntaxhighlight lang="lua">
bool dxAddRenderFunction ( DxElement dxElement, function handlerFunction )
</syntaxhighlight>
{{OOP||DxElement:addRenderFunction}}

===Required Arguments===
*'''dxElement:''' element you wish to bind a render function to
*'''handlerFunction:''' the handler function you wish to bind

===Returns===
Returns true if the function was bound successfully, false otherwise.

==Example==
This example sets a DxWindow to a random position every time it is hovered over, using a render function.
<syntaxhighlight lang="lua">
local screenWidth, screenHeight = guiGetScreenSize()
local window = DxWindow:new(0, 0, 100, 35, "My Window")

function myRenderFunction()
if(isMouseOverDxElement(window)) then
dxSetPosition(window, math.random(screenWidth), math.random(screenHeight))
end
end

dxAddRenderFunction(window, myRenderFunction)
</syntaxhighlight>

'''Note:''' inside a bound render function, you can also use the predefined variable "self" (instead of "window", in this instance).
