Is it just me, or
are custom control (actionscript) components really really difficult to get your
head around?
I am struggling with
just about every aspect of creating custom controls, from deciding what to
extend, through sizing/layout, right down to event
handling.
I have created some
custom controls but they have never turned out to be what I really
wanted.
There is a real lack
of documentation about this subject. I've read the Flex Components PDF,
and I've read the relevant parts of Developing Flex Apps, but none of these
really covers creating components in actionscript from scratch through to more
advanced components at reasonable steps. Some of the more basic examples that
are given require you to draw a circle in Flash first - I don't want to (and I
know I shouldn't) have to use Flash to create a basic custom
component.
I would like a more
in-depth discussion of what the various sizes are - _measuredXXX, preferredXXX,
defaultXXX properties etc
A clearer
explanation of the instantiation and display order/process.
Perhaps a breakdown
of some existing components that have both been built from scratch and has
extended other components.
Anyone else finding this topic hard going like
me?
Kind Regards,
Simon
