Re: [macroid] How to show/hide a list of generated buttons

[Nick Stanchenko]

Hi,

My guess is that “buttonSlots.toList <~ hide” already returns a UI action, which you then wrap into another Ui. Removing the outer Ui should do the trick.

Hello,

I am generating a series of buttons using a function like this:

val buttonSlots = ListBuffer[Option[ImageButton]]()

def createButton() = {
    var buttonSlot = slot[ImageButton]
    val button = w[ImageButton] <~ wire(buttonSlot) <~  res(R.drawable.crosshair) <~ On.click {Ui { buttonSlots.toList <~ hide } }
    buttonSlots += buttonSlot
    button
}

Hiding the buttons as a list, as is done in the click handler, does not work.  Would you know why?  There is no exception; just nothing happens.  I have tried many variations, to no avail.  Thanks!
