Hi, I'm fairly new to Flex and I'd appreciate your help. I'm trying the
following:
I have a DataGrid with 28 columns representing a calendar of some sort with
"dropEnabled" set to "true" and all the drop events defined (dragEnter,
dragExit, dragDrop). This part works very well.
The leftmost column, which is locked ("lockedColumnCount=1"), represents
resources and the other columns have a count of defects associated to each
resource at a specific date.
I also have a List with "dragEnabled" set to "true". This list contains a list
of defect objects which are different than what is displayed in the DataGrid.
When the user clicks on a number of defects displayed in the DataGrid for a
resource, the list of defects is displayed in the list.
My goal is to be able to drag a defect displayed in the list to a new resource
/ date location in the DataGrid and update the counts displayed.
So far, I'm able to get the row (through "calculateDropIndex") but I am unable
to figure out the column.
I tried calculating the column from the mouse position (x) by adding the
columns widths as I iterate through the columns this way:
===========================================================
private function calculateDropColumn(event:DragEvent):int {
var colWidth:int = 0;
var mouseXpos:int = event.localX;
var dropTarget:DataGrid = DataGrid(event.currentTarget);
for (var i:int = 0; i < dropTarget.columns.length; i++) {
if (mouseXpos >= colWidth && mouseXpos <= (colWidth +
dropTarget.columns[i].width)) {
return i;
}
colWidth += dropTarget.columns[i].width;
}
return -1;
}
===========================================================
It works fine until I start scrolling the columns to the right...
I saw that the DataGrid maintains an Array of "visibleColumns" and
"visibleLockedColumns" internally through the debugger, but they are not
exposed (mx_internal namespace).
Anybody has a better way? Am I using the correct component for this kind of
thing? Is there a way to determine the "visibleColumns" another way?
Thanks for your help as I am at a lost...
Marc
