Hi all,
I have defined custom data grid with checkbox. I am not able to
disable the checkbox coming as a part of header field of the data grid.
Custom component is defined as follows.
public class CheckBoxDataGrid extends DataGrid
{
override protected function selectItem(item:IListItemRenderer,
shiftKey:Boolean,
ctrlKey:Boolean,
transition:Boolean =
true):Boolean
{
// only run selection code if a checkbox was hit and always
// pretend we're using ctrl selection
if (item is CheckBox)
return super.selectItem(item, false, true, transition);
return false;
}
// turn off selection indicator
override protected function drawSelectionIndicator(
indicator:Sprite, x:Number, y:Number,
width:Number, height:Number, color:uint,
itemRenderer:IListItemRenderer):void
{
}
// whenever we draw the renderer, make sure we re-eval the checked
state
override protected function drawItem(item:IListItemRenderer,
selected:Boolean = false,
highlighted:Boolean = false,
caret:Boolean = false,
transition:Boolean =
false):void
{
if (item is CheckBox)
CheckBox(item).invalidateProperties();
super.drawItem(item, selected, highlighted, caret, transition);
}
// fake all keyboard interaction as if it had the ctrl key down
override protected function keyDownHandler(event:KeyboardEvent):void
{
// this is technically illegal, but works
event.ctrlKey = true;
event.shiftKey = false;
super.keyDownHandler(event);
}
}
Thanks & Regards,
Namrata
