Created page with " local oref = Obj.Create (str) Create a gui object of the given type as specified by the string str. e.g. local form = Obj.Create ("TForm") instantiates a TForm object and as..."

New page

local oref = Obj.Create (str)

Create a gui object of the given type as specified by the string str. e.g.

local form = Obj.Create ("TForm")

instantiates a TForm object and assigns form a pointer to this object. Access members, methods, and event handlers of an object using dot notation:

form.Caption = "Test"
form.OnClose = function (pSender) Obj.Exit() return
form.Show()

An object's set event handlers won't be active until the script enters an Obj.Loop call. See objects.txt in the openeuo distribution for available objects, their inheritance hierarchies, and associated members.
