Scalar properties should take input from Int32

[Daniel Scott Matthews]

I just noticed that I can't directly connect an int32 to the rotation
value properties of Orientation (X,Y,Z). In this case I wanted the
angles to change by set amounts over a range, not continuously.

Given that there is no loss of data in the int32 to Scalar conversion,
is there any reason why I can't make such a connection?

I can easily script around it, I just wondered if there was a reason
behind the restriction.

Also the Text property of Annotation nodes should be smart enough to
take input from any type of property without the user having to do the
conversion.

And the bounds and sensitivity of the position values (X,Y) for
Annotation2D are inappropriate too, can they be constrained to +-1
with a step of 0.1 on the up/down arrows?

Could the bounds and stepping be user/script editable or is it fixed
at compile time by how GTK does GUI controls?

I don't say it that often, but in this case it just wasn't designed to
work that way.

Same answer.

Yes, see the latest in the main repo.

Thanks, just grabbed those changes.

If I am using a StringSourceScript for the Text property of
Annotation2D and I have a user property added to Annotation2D how do I
reference the name of the connected node? So that I can set the string
to Var Name: Value  e.g. "Position.X 3.86"

like this:
Annotation2D.text --> StringSourceScript.userprop1 --> Position.X -->
myobjectnode.

Where I am doing a simple str(userprop1) in the script at the moment
but want a reusable script that is smart enough to list var name and
value.

I want to feed a string containing dynamic to the Text property of Annotation2D,
that data may be a floating point value.

I want to also display the Name of the property as well as the value,
the text string need to contain both.

I wish to do this with a scripted node StringSourceScript and I wish
to be able to reuse the script so it needs to know what it is
connected too. i.e I don' t want to have Output = "Rotation Z" +
str(mydata) I want Output = mylabel + str(mydata)

see attached example, that needs the label code, but has the var code.

What you want is something along the lines of:

#python

p = Node.get_property("mydata")
s = Document.get_dependency(p)

if s:
        Output = s.name() + ": " + str(p.pipeline_value())
else:
        Output = str(p.pipeline_value())

Tim
