There should be a UIComponentDescriptor in a .descriptor property on any UIComponent instantiated by MXML.
I would probably subclass ComboBox, and have it assign itself to the dropdownFactory. However, if you don't want to do that and know what properties you want to steal, I would subclass DG and steal it in commitProperties from its .owner property and not bother with the UIComponentDescriptor Some things like labelField are passed down for you. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of reflexactions Sent: Tuesday, December 04, 2007 9:40 PM To: [email protected] Subject: [flexcomponents] Re: ComboBox with a dropdown DataGrid Ah yes, I can create a custom ClassFactory. I "could" pass a reference to the Combo into the custom ClassFactory so it could read custom properties off the Combo at run time, and also fire an event to allow the devs to customise the Grid before it is passed in to the Combo in getDropDown. In theory I would think (though I dont know how) it is possible to have it read a descriptor from the Combo and instantiate a grid based on the descriptor. The descriptor being some tags set in the mxml? --- In [email protected] <mailto:flexcomponents%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > You would use a custom factory or the properties bag in ClassFactory to > customize the grid.
