[gphoto-devel] Another issue regarding widgets readonly implementation....

[Henrik A. <hen...@gm...>]

... i noticed this is a fairly new implementation (anyway to the library
user...) dont know how it works behind the curtains..

I have a problem, my application does get notified when readonly changes on
a widget and it seems to work good, but
there are not all widgets that does update this as it seems.. for an
example..
My D60 when i turn camera into manual mode i got notified that widget
shuttertime and f-number has changed it's readonly flag to false,
when i turn down to Exp. Program "Auto" i suspect that both shuttertime and
f-number should be readonly, but this is not the case
and when my application not get this notify i can make changes to widgets
which result in onError() telling im trying to change
a readonly widget...

Im not telling it might be a problem in gphoto library, it might ofcourse be
the case that my CameraConfiguration class implementation
might not work 100% and some changes got dropped between the chairs..

I just want to know that this does work 100% in gphoto implementation and
there is no misses regarding the readonly flag.
so i could spent some time on right thing...


heres some background on my cameraconfiguration class

CameraConfiguration holds an local copy CameraWidget ** of root
configration, initialized in constructor..
then on a thread i wait for events and on prop change event
CameraConfiguration is reading a temp copy of widgets
and "merges" change into the class local copy, when widgets A widget and B
widget differs in readonly flag A is updated
with B readonly status and a observer callback is signaled to push the
accessibility change further to my application...
