Hi all,
I try to progammatically set values of widgets like sliders or checkboxes.
When I use "WIDGET_CONTROL,myWidget,SET_VALUE=myValue", only the widget
gets changed, but the appropriate event is not generated.
What I am looking for is a technique taht allows me to change the value of
a widget _and_ generates the event that would have been generated if I
had changed the widget using the mouse or keyboard.
Thanks for all tips,
Sebastian

Or, if you know you are looking for the "SEND_EVENTS" keyword,
I expect you can find it. Good luck otherwise.
But IDL documentation is changing. I expect to find this under
"Widgets, sending events to" and sure enough in IDL 5.6 on-line
help (but nothing earlier) I find exactly that. Hooray!
Cheers,
David

I'd re-define what I meant by "replay mode". What would
you do? :-)
Cheers,
David
P.S. Many of my objects are already written to be
optionally executed in a "No Dialog" mode. This is handy,
for example, when you have added functionality to a program
and you want to update old data files, etc. You don't
have to ask the user what file name they want, etc. You just do
it. I presume something similar could be invoked here, although
I admit knowing something might be recorded up front gives
you more design flexibility than learning about it at the end
of the project. :-)

Now chew on this: How would you get your customer's program (in replay
mode) to get past a call to e.g. DIALOG_PICKFILE 8-)
By the way, if you want to peek at how e.g. the cursor was animated,
the original xrecorder.pro is at
http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/widgets/xre corder.pro

Check out DEMO, /RECORD and DEMO_TOUR. They make and play editable macros.

I think such a thing could be built in a couple of
minutes with the object widget library Dave and I
are developing. In our system, all widget object
events are handled by the same event handler. All
that would be required is to pass the event structures
on to the "recorder" object (probably my linked list
object, since it is already written). It would be
easy enough, I think, to be able to record and store
"macros" since interaction is with objects, not widgets.
Ah, good, something for me to fool around with once the
presents are opened Christmas morning! :-)
Happy Holidays!
David
P.S. Let's just say if I wanted a real life, I'd probably
get a real job. :-)
