Re: [flexcoders] DataGrid Renderer and referencing back

[JesterXL]

Here's the basic steps for Flex 1.5: - put a button in your cellrenderer - if ActionScript, register for the click event, and provide a click function delegate in the cell renderer - if MXML, point click event to a event handler function in the cellrenderer - in your event handler for the button's click, have it dispatch an event   - in your DataGrid container, register for the custom click event; can only do this via code since you made up the event name, and DataGrid.as won't have your event in the metadata   So, some psuedo code for your cellrenderer:   var ref:Button = Button(createChild(Button)); ref.addEventListener("click", Delegate.create(this, onClick));   function onClick(event:Object):Void {     listOwner.dispatchEvent({type: "makeNameForThisEventMeaningful", target: listOwner, bubbles: true}); }   And, some code for your container:   function onCreationComplete() {     yourDataGrid.addEventListener("makeNameForThisEventMeaningful", Delegate.create(this, onClicked)); }   function onClicked(event:Object):Void {     // button was clicked in datagrid, do HTTPService.send stuff }   Make sense?       ----- Original Message ----- From: Jonathan Miranda To: flexcoders@yahoogroups.com Sent: Tuesday, January 31, 2006 1:13 PM Subject: RE: [flexcoders] DataGrid Renderer and referencing back Hey jester, thanks for the reply but could give a real basic example of this? I’m having issues with “bubbling” .I found a semi-example on CFlex and working with that so far using this.dispatchEvent(someEventObject);   So would I need someEventObject in both the application mxml and the renderer mxml so that it would call both?   _________________________________________ Jonathan Miranda Flexible Master of the Web "In the game of chess, it's important to never let your opponent see your pieces."   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of JesterXL Sent: Tuesday, January 31, 2006 10:50 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] DataGrid Renderer and referencing back   You can dispatch an event that bubbles in your cellrenderer, and your main app can catch this event, and then resend the HTTPService.  Since the event is not internal to DataGrid's metadata, you can only subscribe via code.   ----- Original Message ----- From: Jonathan Miranda To: flexcoders@yahoogroups.com Sent: Tuesday, January 31, 2006 12:29 PM Subject: [flexcoders] DataGrid Renderer and referencing back   I have a custom cellRenderer which has a button in it and when that button is pressed, I want to force the datagrid to resend it’s HTTPService to get an update. How can I reference my HTTPService in the main app, when my custom cellRenderer is in a separate mxml file?   _________________________________________ Jonathan Miranda Flexible Master of the Web -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com YAHOO!
