[flexcoders] Re: Accessing a custom cellrenderer
Look at the code below and try in similar lines in your cellRenderer file:
var rowIndex : Number;var columnIndex : Number;var getCellIndex : Function; // the function we receive from the listvargetDataLabel : Function; // the function we receive from the listfunction setValue( str:String, item:Object, sel:Boolean ) {//Dumper.info("@@This cell belongs to:" + str);if(rowIndex == undefined || columnIndex == undefined){rowIndex = getCellIndex().itemIndex;columnIndex = getCellIndex().columnIndex;}var projectMemberVO : ProjectMemberVO = ProjectMemberVO(item);var projectMemberWeekArray : Array = projectMemberVO.projectMemberWeekArray;if(!isNaN(Number(projectMemberWeekArray[columnIndex].forecastHours)) Number(projectMemberWeekArray[columnIndex].forecastHours) != 0) {//Dumper.info("projectMemberWeekArray[columnIndex].forecastHours setting to weekHoursForecast.text");weekHoursForecast.text = projectMemberWeekArray[columnIndex].forecastHours;} else{weekHoursForecast.text = "";}}function updateWeekHoursDataProvider(){if (!isNaN(weekHoursForecast.text)){ModelLocator.currentProject.projectTeamVO.projectMembersArray[rowIndex].projectMemberWeekArray[columnIndex].forecastHours = weekHoursForecast.text;}}

[flexcoders] Re: Accessing a custom cellrenderer
Plenty of ways to accomplish this; one way is to provide a click
handler for your checkbox, and then set a property of the
corresponding dataprovider item that you can then examine from
another function. Cell renderers automatically get passed
references to some handy objects and functions that you can use.
var listOwner: MovieClip; // the reference to the list
var getCellIndex: Function; // the function we receive
function onCheckboxClicked(event) {
listOwner.dataProvider.getItemAt(
getCellIndex().itemIndex).isCheckboxSelected =
event.target.selected;
}
Just add click=onCheckboxClicked(event) to your mx:CheckBox, and
any function can then loop through your dataprovider's items
examining the isCheckboxSelected property to determine the state of
the checkbox.

RE: [flexcoders] Re: Accessing a custom cellrenderer
To summarize, dont try to access
the rendered controls directly. Instead, have the cell renderer update the dataProvider,
then loop over the dataProvider to make your selected array.
