Hi
There is funny workaround for this problem:
n = nuke.createNode("EdgeBlur")
a = n['quality']
knob = (n.name() + '.' + a.name())
print nuke.tcl('knob', '-t', knob)
Above code returns the knob's ID (in this case 3) defined as enum in Knobs.h:
enum {
OBSOLETE_KNOB = 0, // ignored when read from scripts
STRING_KNOB, // char* pointer
FILE_KNOB, // char* pointer, has file chooser
INT_KNOB, // int
ENUMERATION_KNOB, // popup list, sets int to index
BITMASK_KNOB, // int, one button for each bit
BOOL_KNOB, // checkbox
DOUBLE_KNOB, // double
FLOAT_KNOB, // float
ARRAY_KNOB, // 2Darray of floats for Convolve
CHANNEL_MASK_KNOB, // ChannelSet
CHANNEL_KNOB, // 1-4 Channel numbers
XY_KNOB, // 2 numbers for x,y position, draws crosshair
XYZ_KNOB, // 3 numbers for x,y,z position - not proxy scaled
WH_KNOB, // 1 or 2 numbers for width and height
BBOX_KNOB, // 4 numbers for x,y,r,t of a rectangle
SIZE_KNOB, // obsolete, same as FLOAT_KNOB
FORMAT_KNOB, // Store formats into the info_
COLOR_KNOB, // r,g,b
ACOLOR_KNOB, // r,g,b,a
TAB_KNOB, // start a new tab
CUSTOM_KNOB, // you called constructor yourself
PYSCRIPT_KNOB, // Button that runs a python script
TEXT_EDITOR_KNOB, // same as MULTILINE_STRING_KNOB
TRANSFORM2D_KNOB, // A 4x4 transformation matrix with a 2-d affine xform
SPACER_KNOB,
TEXT_KNOB, // helpful text caption
HELP_KNOB, // [?] button with helpful text
MULTILINE_STRING_KNOB, // multi-line text editor
AXIS_KNOB, // 3D 6-DOF transformation
UV_KNOB, // 2 numbers
BOX3_KNOB, // 2 3D points describing a 3D volume
SCRIPT_KNOB, // Button that runs a tcl script

CP_KNOB, // rappresent a roto curve control points
TOOLBAR_KNOB,
TABGROUP_KNOB,
PLUGIN_PYTHON_KNOB, // A user-created knob, with user-provided
python bindings.
EXOGROUP_KNOB,
MENU_KNOB, // A knob which provides a button that opens a menu.
PASSWORD_KNOB, // string_knob with password field
TOOLBOX_KNOB,

Cheers Josh,
My hacky solution to this, as I know I'll only be doing this on gizmos, is
to call makeGroup() on it, and then call
writeKnobs(nuke.WRITE_USER_KNOB_DEFS) on it
, and parse the output, which includes the integer for the knob type...

Hi Hugh,
It looks to me that they've done away wit the Int and Double knob
subclasses in 6.3. I believe the only way to know would be to query
the flags for the knob but i don't see a way to do that. If you test
the type of the values of both of the knobs they both return floats so
that's no indication either. So no I don't think there is currently a
way to decipher between an int and float knob in Nuke at the present
time.

Hi,
I'm trying to interrogate a node to find out more details of what its knobs
are... However, I'm currently finding that, for a number of different knob
types, I'm just getting Array_Knob as the class...
For example, try the following:
n = nuke.createNode("EdgeBlur")
print n['quality'].Class() # Should be Int_Knob, actually gives Array_Knob
print n['edge_mult'].Class() # Should be Double_Knob, actually gives
Array_Knob
Is this a bug? And does anyone know how I can get at the actual type of
these knobs...?
Cheers
