"Best practice" for creating a custom control

[Jérôme Rosat]

Hello everybody,

I'm looking for a kind of "best practice" for creating custom controls. For example, how to access the data of the custom control ? Do we have to use custom properties or a setProp or getProp handlers  or both ? Is it preferable to use a prefix for naming a command ? And for custom properties, do we have to use a set of properties ? With a "standard name" ? Etc.

Thank you for you help.

Jerome
