[flexcoders] Using ContextMenu with DataGrid
What is the proper way to get the rowIndex into my dataProvider when using a context menu? Here's a few things that I tried and why they didn't work: 1) Cast event.mouseTarget to the DataGridItemRenderer and used listData.rowIndex property. This doesn't work because rowIndex is really the index of the row currently being displayed and is, therefore, wrong once you've scrolled down. 2) Cast event.mouseTarget to the DataGridItemRender and then used it's data property to access the item directly. This (and #1 above) doesn't work because I also use other or custom item renderers. 3) Use the DataGrid's contextMenuY property, the height property and the size of my list in order to calculate the position. I believe I can get this to work ... IF I assume that the row height distribution is normal AND that there are no margins, borders, etc. This seems very brittle. 4) [Untested] I suppose I could use the contextMenuY as above, but then use the ListRowInfo array to make sure to include margins, etc. but I'm still not positive if the contextMenuY does or does not include any special margins, styles, etc. So, I still haven't found a good way to do it. Suggestions very welcome. Thanks. --Kaleb
[flexcoders] Using ContextMenu
Hi All,
I want to display right-click context menu only in the canves area.
Can someone please tell me how to do this?.
My code displays context menu in the whole application. Not only
canves area.
Thanks,
Prasad

Re: [flexcoders] Using ContextMenu
Can't do it in the current version of the flash player... possibly in a few months when the next version comes out?
Not something I'd code against though.
Search the group for double click as the only alternative I found to offer a second mouse action.

RE: [flexcoders] Using ContextMenu
Hi,
Right, you can not attach context menu on nested object.
This is a known issue which has been fixed in Macromedia Flash Player
8.
But you can use some workarounds to attach/de-attach
context menu. When mouse is over Canvas attach the context menu and when mouse
is out of Canvas remove the context menu(by clearing customItems
array).
Does it make sense?
