Dear Josh,
I have been working on the bug #1060837:
https://bugs.launchpad.net/inkscape/+bug/1060837

(Please go through the link to know about the bug)

The bug involves depicting the CMS values of a CMYK using Color Space on a scale of [0,100] rather than the default [0,1]. 

I have up till now setup un-editable GtkEntry Values which shall depict the values that the artist wants ( on the 0 to 100 scale ).
Here is a screen-shot:

I am facing to problems:
1) How to distinguish that a CMYK based color-space is selected ?
I am accessing the Colorspace through the ColorProfile object like this-

if( asICColorSpaceSig(newProf->getColorSpace() ) == cmsSigCmykData ) {
_cmsCMYK = TRUE ;
}
else {
_cmsCMYK = FALSE ;
}

I have placed this snippet in appropriate places (_setProfile function, _profileChanged function etc ). But nothing seems to really work . Am I using the correct equality condition ? Can you help in this ?

2) How to setup a GtkEntryBuffer for the GtkEntries I have drwan for the artist ?

I wrote a small function:

char* getAdjustmentVal (GtkAdjustment *_adj)
{
gdouble _val=gtk_adjustment_get_value (_adj);
_val=100.00*_val;
guint _corrVal= _val;
char* arr;
itoa( _corrVal, arr, 10 );
return arr;
}

then I used:

gtk_entry_buffer_set_text( ....) 
https://developer.gnome.org/gtk3/3.4/GtkEntryBuffer.html#gtk-entry-buffer-set-text

but I end of getting runtime errors. 
The sequence of loading the data before drawing the widget to screen is correct. But I get runtime errors. Maybe because the set text function requires a const array. Any suggestions on that ? What changes are required in the function ?
