FUNCTION

You supply an array of MUI_Palette_Structures here, each entry defining one color:

struct MUI_Palette_Entry
{
   LONG  mpe_ID;
   ULONG mpe_Red;
   ULONG mpe_Green;
   ULONG mpe_Blue;
   LONG  mpe_Group;
};

mpe_ID

This entry is not used by palette class, you can put in whatever you want, except the value MUIV_Palette_Entry_End (==-1), which terminates the array.

mpe_Red

32-bit red component of the current color. This field will be changed by palette class whenever the user edits the color.

mpe_Green

32-bit green component of the current color. This field will be changed by palette class whenever the user edits the color.

mpe_Blue

32-bit blue component of the current color. This field will be changed by palette class whenever the user edits the color.

mpe_Group

Entries with the same mpe_Group value are concatenated. Whenever a new color in the listview is selected, all other colors with the same mpe_Group get selected as well and get adjusted all at once. Entry concatenation can be changed by the user, as long as you don't disable this feature with the MUIA_Palette_Groupable attribute.
