New API doc - typos and questions

The enableVCB? method is used to tell SketchUp whether to allow the user to enter text into the VCB (value control box, aka the "measurements" panel). If you do not implement this method, then the vcb is disabled by default.

I've never used this method for my Tools. But the VCB has still worked.

Image.size=

It appears that the second argument is optional.

Entity.entityID
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/entity.html#entityID

@unknownuser said:

The entityID method is used to retrieve a unique ID assigned to an entity.

The entityID is not persistent between sessions.

Is it persistent within a session? Can it be relied on for the length of one session?

ComponentDefinition.guid
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/componentdefinition.html#guid

Is this value persistent between sessions?

Sketchup::Color.new

new can accept a hex value (not string) as the parameter: for example 0xFF0000 (undocumented)

But, it reverses the red and blue values. Here is a Console session. (bug)


Sketchup;;Color.new 0xFF0000
Color(  0,   0, 255, 255)
Sketchup;;Color.new 0x0000FF
Color(255,   0,   0, 255)

I've got some catching up to do. Thanks for all of the details, guys!

ModelObserver.onDeleteModel vs ModelObserver.onEraseAll
http://code.google.com/apis/sketchup/docs/ourdoc/modelobserver.html#onDeleteModel

When does the onDeleteModel event trigger? I don't think I've ever seen it trigger. When I open an existing model or create a new model onEraseAll is triggered.

UI.start_timer

This post on the API blog is showing start_timer with a fraction of a second resolution. In my experience, UI.start_timer has a whole second resolution and rounds partial seconds down to the nearest second.


    t1=Time.now; UI.start_timer(0.1) {p Time.now-t1} ==> 0.01
    t1=Time.now; UI.start_timer(0.999) {p Time.now-t1} ==> 0.01
    t1=Time.now; UI.start_timer(1) {p Time.now-t1} ==> 1.001
    t1=Time.now; UI.start_timer(1.9) {p Time.now-t1} ==> 1.002

Point3d.linear_combination

Uses example from Geom.linear_combination.

I would guess the Point3d.linear_combination would only take 2 arguments - the weight, and other point since the first point is the receiver of the method.

MaterialsObserver
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/materialsobserver.html

Observer events that doesn't trigger:
Sketchup 6
onMaterialChange*
onMaterialRefChange

Sketchup 7
onMaterialChange*
onMaterialRefChange
onMaterialSetCurrent

Only triggers when the name changes. Not when any of the other properties changes.

Group.move!

@unknownuser said:

This method is the same as the transform! method except that it does not record the move in an undo operation. This method is useful for transparently moving things during an animation.

.move! resets the rotational and scaling components of the receiver's transformation, and does not result in the same final translation as using .transform!

Layer.page_behavior vs Layer.page_behavior=
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/layer.html#page_behavior

The flag values seems to contradict between descriptions of the two methods.

Pages.add_frame_change_observer
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/pages.html#add_frame_change_observer

I don't find any more info on this FrameChange observer. Missing documentation?

@unknownuser said:

The argument is an object that implements a method frameChange with the following form:

But then there's no example. And no FrameChange observer is listed in the Observer list.

Transformation.to_a
http://code.google.com/apis/sketchup/docs/ourdoc/transformation.html#to_a
It would be every helpful if this listed the many items in this array and explained which each of them represents
e.g. tra[14]= Z value
...
