Implemented Interfaces

GtkToolPalette implements AtkImplementorIface, GtkBuildable, GtkOrientable and GtkScrollable.

Includes

#include <gtk/gtk.h>

Description

A GtkToolPalette allows you to add GtkToolItems to a palette-like container with different categories and drag and drop support.

A GtkToolPalette is created with a call to gtk_tool_palette_new().

GtkToolItems cannot be added directly to a GtkToolPalette - instead they are added to a GtkToolItemGroup which can than be added to a GtkToolPalette. To add a GtkToolItemGroup to a GtkToolPalette, use gtk_container_add().

GtkWidget *palette, *group;
GtkToolItem *item;

palette = gtk_tool_palette_new ();
group = gtk_tool_item_group_new (_("Test Category"));
gtk_container_add (GTK_CONTAINER (palette), group);

item = gtk_tool_button_new (NULL, _("_Open"));
gtk_tool_button_set_icon_name (GTK_TOOL_BUTTON (item), "document-open");
gtk_tool_item_group_insert (GTK_TOOL_ITEM_GROUP (group), item, -1);

The easiest way to use drag and drop with GtkToolPalette is to call gtk_tool_palette_add_drag_dest() with the desired drag source palette and the desired drag target widget . Then gtk_tool_palette_get_drag_item() can be used to get the dragged item in the “drag-data-received” signal handler of the drag target.
