Hi all!!
I've designed an extension of AdvancedDataGrid for incorporating a set
of customer's commitments about tabular data. All works fine but a
single thing: I've the need to (optionally) display the total number of
elements in data provider just above the datagrid, such as:
Rows: 10/87
----------------------------------
| header 1 | header 2 | header 3 |
----------------------------------
| | | |
| | | |
| | | |
----------------------------------
I've tried to implement that by adding a "Label child" just above the
datagrid:
override protected function createChildren() : void {
this._lblNumberOfRows = new Label();
this._lblNumberOfRows.text = "I'm a try!";
this.addChild(this._lblNumberOfRows);
super.createChildren();
}
override protected function measure() : void {
super.measure();
this.measuredWidth = Math.max(this.measuredWidth,
this._lblNumberOfRows.measuredWidth);
this.measuredHeight += this._lblNumberOfRows.measuredHeight;
}
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void {
this._lblNumberOfRows.invalidateDisplayList();
super.updateDisplayList(unscaledWidth, unscaledHeight);
}
But it seems it doesn't works at all... The label don't get displayed
just as I haven't overridden above methods.
How can I achieve such task?
I have to keep the inheritance from AdvancedDataGrid because I have to
rewrite all the other functionalities otherwise... A lot of work :S So I
would prefer avoiding to resort to composition of label and datagrid
while inheriting from VBox.
Thank you very much in advance!
