Declaration [src]
void
gtk_color_chooser_add_palette (
GtkColorChooser* chooser,
GtkOrientation orientation,
int colors_per_line,
int n_colors,
GdkRGBA* colors
)
Description [src]
Adds a palette to the color chooser.
If orientation is horizontal, the colors are grouped in rows,
with colors_per_line colors in each row. If horizontal is FALSE,
the colors are grouped in columns instead.
The default color palette of GtkColorChooserWidget has
45 colors, organized in columns of 5 colors (this includes some grays).
The layout of the color chooser widget works best when the palettes have 9-10 columns.
Calling this function for the first time has the side effect of removing the default color palette from the color chooser.
If colors is NULL, removes all previously added palettes.
