## gtkColorSelectionSetChangePaletteHook

### Description

This function should save the new palette contents, and update the GtkSettings property "gtk-color-palette" so all GtkColorSelection widgets will be modified. WARNING: `gtk_color_selection_set_change_palette_hook` has been deprecated since version 2.4 and should not be used in newly-written code. This function does not work in multihead environments. Use `gtkColorSelectionSetChangePaletteWithScreenHook` instead.

### Usage

    gtkColorSelectionSetChangePaletteHook(func)

### Arguments

``func`` | a function to call when the custom palette needs saving.
