Object Oriented Programing: Include a rollout as a member?

[Anonymous]

Try this one:

struct trafficLine
    (
    name = "the name of the type",
    info = "some describ",
    image = "a preview image path",
    width = 0.15,
    length = 4.0,
    spacing = 2.0,
    guideLine = #(),
    Poly = #(),
    fn makePoly =
        (
        if isValidNode poly and poly != undefined do delete poly
        tempPart = plane width:width length:length
        Poly = MakeStripPoly guideLine tempPart  spacing  0.5 off --To make the test work, this line may be replaced by "poly = plane( )".
            
        delete TempPart

        poly
        ),
    
    fn resetGuideline = 
        (
        guideLine = undefined
        ),
    
    fn resetPoly = 
        (
        poly = undefined
        ),
        
    panel = rollout panel name
        (
        button apply "apply"
        on apply pressed do makePoly()
        ),
        
    fn makePanel =
        (
        try destroyDialog panel catch()
        createdialog panel
        )
    )

a = trafficLine ()
a.guideline = circle()
a.makePanel()

well, it's all fine till you press the botton "apply".

I"m trying to make the UI defination as part of the object, is that possible?


(In fact, I've already solved this case in another way: I create a rollout outside the struct defination and a initiallizePanel( ) inside.)

Did you try passing in the instance of a trafficLine to the makePanel function? The following 'create, then initialize' worked for me

struct trafficLine
(
    -- <same original stuff>

    panel = rollout panel name
    (
        button apply "apply"
        local makePolyFn = undefined
        on apply pressed do if (classof makePolyFn == MAXscriptFunction) then makePolyFn()
    ),
         
    fn makePanel owner =
    (
        try destroyDialog owner.panel catch()
        createdialog panel
        panel.makePolyFn = owner.makePoly    -- initialize the panel
     )

)

a = trafficLine()
a.guideline = circle()
a.makePanel(a)      -- Pass in the owner, sorta like a 'this" argument...

Nice! I hadn't tried assigning it to a member. Thanks for that.
