Re: [Dynapi-Widgetdev] Select list widget

[Ben E. <ben...@ea...>]

Hmm, I tried what you said, but got the error 'label.css is null or not an
object'. I don't understand! The line that throws the error is
'o.label.css.padding="3px"'.

function selectList(title) {
 this.superClass=DynLayer
 this.superClass()
 this.id="selectList"+(selectList.Count++)

 this.moveTo(100,100)
 this.setSize(500,350)
 //this.setBgColor('black')

 var l=new EventListener(this)
 l.oncreate=function(e) {
  var o=e.getTarget()

  o.label = new Label('')
  o.label.moveTo(0,0)
  o.label.setBgColor('#eeeeee')
  o.label.setWidth(233)
  o.label.setHeight(25)
  o.label.setHTML('<b>Click to expand list</b>')

  o.label.css.padding="3px"
  o.label.css.borderWidth="2px"
  o.label.css.borderColor="black"
  o.label.css.borderStyle="solid"

  o.list = new List()
  o.list.moveTo(0,-75)
  o.list.setWidth(250)
  o.list.setBgColor('#000000')
  o.list.boldOnSelect(true)
  o.list.add("Item One",10)
  o.list.add("Item Two",20)
  o.list.add("Item Three",30)
  o.list.add("Item Four",'test')

  o.button = new DynLayer(null,233,0,17,25)
  o.button.imgUp = new Image()
  o.button.imgUp.src =
'../dynapi2_51/dynapi/src/lib/dynapi/images/scrollpane/arrowdn0.gif'
  o.button.imgDn = new Image()
  o.button.imgDn.src =
'../dynapi2_51/dynapi/src/lib/dynapi/images/scrollpane/arrowdn1.gif'
  o.button.setBgImage(o.button.imgUp.src)

  o.addChild(o.list)
  o.addChild(o.label)
  o.addChild(o.button)

  o.button.events = new EventListener(o.button)
   o.button.events.onmousedown=function(e){
    o.button.setBgImage(o.button.imgDn.src)
   }

   o.button.events.onmouseup=function(e){
    if (!o.list.open) {
     o.list.slideTo(0,25,20,5)
     o.list.open=true
    } else {
     o.list.slideTo(0,-75,20,5)
     o.list.open=false
    }
    o.button.setBgImage(o.button.imgUp.src)
   }
  o.button.addEventListener(o.button.events)

  o.list.events = new EventListener(o.list)
   o.list.events.onselect=function(e){
    o.label.setHTML(o.list.getSelectedItem().getHTML())
    o.list.slideTo(0,-75,20,5)
    o.list.open=false
   }
  o.list.addEventListener(o.list.events)

 }
 this.addEventListener(l)

 return this
}
selectList.Count=0
selectList.prototype=new DynLayer()
selectList.prototype.getSubClass=function() { return button }
