Any thoughts on this?

Cheers, Josh

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: [image: Inline image 1]

*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 ?

[ _cmsCMYK is a bitfield [ gboolean _cmsCMYK : 1 ] added to the sp-icc-color-selector.h file or Color Selector class as a flag to keep track of only CMYK color spaces.]

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-se...

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 ?
