i would achieve this thus:
// calculate the total space required to render the string (string here contains no spaces):string_width_in_pixels = string_width(string_to_render); // string_width() function is implementation specific
// leaving us with how much white space is required to be inserted:total_white_space_in_pixels = label_widget_width_in_pixels - string_width_in_pixels;
// compute the pixels for a space (' '):space_pixels = string_width(" ");
// total white space required between each characterspace_fill_in_pixels = total_white_space_in_pixels / (total_characters_in_display_string - 1)
spaces_required = space_fill_in_pixels / space_pixels;
and now we have enough information to make our string by hand, one character at a time, evenly distributing the displayed characters:
for(i=0;i<strlen(string_to_render);i++){ sprintf(output_str, "%s%c\0", output_str, string_to_render[i]); for(j=0;j<spaces_required;j++) { sprintf(output_str, "%s%c\0", output_str, ' '); }}
et voila, our evenly spaced output string. (though in practice i would write the above using glib string functions and not implement it strictly as i have written here.)
no? ja?
