hey EraserX,
i did some more digging and found a possible workaround. thanks to Flash Builder i was able to snoop around the Picker class via extending it with a custom class. turns out the button is a protected value therefore totally accessible via extending the class. to summarize i basically took the setButtonSkin method and overrode it and then modified the __buttonBackground (turns out its a button so its skinnable via its own setSkin method).
CustomPicker.as:
package
{
import qnx.ui.picker.Picker;
public class CustomPicker extends Picker
{
public function CustomPicker()
{
super();
}
override public function setButtonSkin(skin:Object):void
{
this.__backgroundButton.setSkin(skin);
}
}
}
so from now on instead of creating a Picker() object, you can create a CustomPicker() object.
// A short example of a picker component that displays
// day, month and year.
package
{
import flash.display.Sprite;
import flash.events.Event;
import qnx.ui.data.DataProvider;
import qnx.ui.picker.Picker;
import qnx.ui.skins.picker.PickerButtonSkinBlack;
import qnx.ui.skins.picker.PickerListBackgroundBlack;
import qnx.ui.skins.picker.PickerSelectionBlack;
import qnx.ui.text.Label;
[SWF(height="600", width="1024", frameRate="30", backgroundColor="#BBBBBB")]
public class PickerSample extends Sprite
{
public function PickerSample()
{
// Create three arrays to handle days, months, years.
var arrDay:Array=[];
var arrMonth:Array=[];
var arrYear:Array=[];
// Populate the month array and create the
// day DataProvider
for (var i:int=1; i<32; i++) {
arrDay.push({label: i.toString()});
}
var dayDP:DataProvider=new DataProvider(arrDay);
// Populate and month array and create the month
// DataProvider
arrMonth.push({label: "January"});
arrMonth.push({label: "February"});
arrMonth.push({label: "March"});
arrMonth.push({label: "April"});
arrMonth.push({label: "May"});
arrMonth.push({label: "June"});
arrMonth.push({label: "July"});
arrMonth.push({label: "August"});
arrMonth.push({label: "September"});
arrMonth.push({label: "October"});
arrMonth.push({label: "November"});
arrMonth.push({label: "December"});
var monthDP:DataProvider=new DataProvider(arrMonth);
// Create the year DataProvider
for (var l:int=1900; l<2015; l++) {
arrYear.push({label: l.toString()});
}
var yearDP:DataProvider=new DataProvider(arrYear);
// Add the day, month and year DataProviders to the main
// array
var dpp:Array = new Array();
dpp.push(dayDP);
dpp.push(monthDP);
dpp.push(yearDP);
// Create the picker and add the main DataProvider
var picker:CustomPicker = new CustomPicker();
picker.setListBackgroundSkin(PickerListBackgroundBlack);
picker.setSelectionSkin(PickerSelectionBlack);
picker.setButtonSkin(PickerButtonSkinBlack);
picker.width=400;
picker.height=50;
picker.x=picker.y=300;
picker.dataProvider=new DataProvider(dpp);
addChild(picker);
// To customize column widths,
// all widths are added up and then used for
// a ratio against the component set width
picker.setListWidth(0,100);
picker.setListWidth(1,300);
picker.setListWidth(2,200);
// Set to Jan 1, 2010
picker.selectedIndices=[0,6,111];
// Add listeners for open, close and select events
picker.addEventListener(Event.OPEN,handleOpen);
picker.addEventListener(Event.CLOSE,handleClose);
picker.addEventListener(Event.SELECT,handleSelect);
// A simple function that displays currently selected
// item information in the console.
traceItems();
function traceItems():void
{
for (var j:int = 0; j <picker.selectedItems.length; j++) {
trace("Picker.selectedItems " +picker.selectedItems[j].label);
}
trace("Picker.selectedIndices "+picker.selectedIndices);
trace("Picker.data "+picker.data);
}
function handleSelect(e:Event):void {
traceItems();
}
function handleOpen(e:Event):void {
trace("Picker.open event captured");
}
function handleClose(e:Event):void {
trace("Picker.close event captured");
}
}
}
}
it should ahve the same functionality of the original class just with a modified setButtonSkin() method. i also want to add because this was a total guess i have no idea if we are losing extra functionality. example being if something else was also done within that method i dont know about. but it gets the job done hah hope this helps till they clear up the bug. good luck!
